　　showModalDialog() (IE 4+ 支持)
　　showModelessDialog() (IE 5+ 支持)


window.showModalDialog()Ҏ用来创徏一个显CHTML内容的模态对话框Q由于是对话框，因此它ƈ没有一般用window.open()打开的窗口的所有属性?
window.showModelessDialog()Ҏ用来创徏一个显CHTML内容的非模态对话框?

当我们用showModelessDialog()打开H口Ӟ不必用window.close()d闭它Q当以非模态方式EIE5Q打开Ӟ 打开对话框的H口仍可以进行其他的操作Q即对话框不L最上面的焦点，当打开它的H口QＲQ改变时Q它自动关闭。而模态EQIQ］方式的对话框始终有焦点（焦点不可U走Q直到它关闭Q。模态对话框和打开它的H口相联p，因此我们打开另外的窗口时Q他们的链接关系依然保存Qƈ且隐藏在zdH口的下面?

使用Ҏ如下Q?
vReturnvalue = window.showModalDialog(sURL [, vArguments] [, sFeatures])
vReturnvalue = window.showModelessDialog(sURL [, vArguments] [, sFeatures])
参数说明Q?
sURL
必选参敎ͼcdQ字W串。用来指定对话框要显C的文档的URL?
vArguments
可选参敎ͼcdQ变体。用来向对话框传递参数。传递的参数cd不限Q包括数l等。对话框通过window.dialogArguments来取得传递进来的参数?
sFeatures
可选参敎ͼcdQ字W串。用来描q对话框的外观等信息Q可以用以下的一个或几个Q用分号?”隔开?
  dialogHeight 对话框高度，不小于１Q０pxQﾃQ４中dialogHeight ?dialogWidth 默认的单位是emQ而ﾃQ５中是pxQؓ方便其见Q在定义modal方式的对话框Ӟ用px做单位?
　　dialogWidth: 对话框宽度?
　　dialogLeft: 距离桌面左的距离?
　　dialogTop: L面上的距R?
　　center: {yes | no | 1 | 0 }Q窗口是否居中，默认yesQ但仍可以指定高度和宽度?
　　help: {yes | no | 1 | 0 }Q是否显C帮助按钮，默认yes?
　　resizable: {yes | no | 1 | 0 } QﾃQ５Q］Q是否可被改变大。默认no?
　　status: {yes | no | 1 | 0 } QIE5+Q：是否昄状态栏。默认ؓyes[ Modeless]或no[Modal]?
  scroll:{ yes | no | 1 | 0 | on | off }Q指明对话框是否昄滚动条。默认ؓyes?

  q有几个属性是用在HTA中的Q在一般的|页中一般不使用?
  dialogHide:{ yes | no | 1 | 0 | on | off }Q在打印或者打印预览时对话框是否隐藏。默认ؓno?
  edge:{ sunken | raised }Q指明对话框的边框样式。默认ؓraised?
  unadorned:{ yes | no | 1 | 0 | on | off }Q默认ؓno?

传入参数Q?
要想对话框传递参敎ͼ是通过vArguments来进行传递的。类型不限制Q对于字W串cdQ最大ؓ4096个字W。也可以传递对象，例如Q?

test1.htm
====================
<script>
  var mxh1 = new Array("mxh","net_lover","孟子E?)
  var mxh2 = window.open("about:blank","window_mxh")
  // 向对话框传递数l?
  window.showModalDialog("test2.htm",mxh1)
  // 向对话框传递window对象
  window.showModalDialog("test3.htm",mxh2)
</script>

test2.htm
====================
<script>
  var a = window.dialogArguments
  alert("您传递的参数为：" + a)
</script>

test3.htm
====================
<script>
  var a = window.dialogArguments
  alert("您传递的参数为window对象Q名Uͼ" + a.name)
</script>

可以通过window.returnvalue向打开对话框的H口q回信息Q当然也可以是对象。例如：

test4.htm
===================
<script>
  var a = window.showModalDialog("test5.htm")
  for(i=0;i<a.length;i++) alert(a[i])
</script>

test5.htm
===================
<script>
function sendTo()
{
  var a=new Array("a","b")
  window.returnvalue = a
  window.close()
}
</script>
<body>
<form>
  <input value="q回" type=button onclick="sendTo()">
</form>

常见问题Q?
1Q如何在模态对话框中进行提交而不新开H口Q?
如果??览器是IE5.5+,可以在对话框中用带name属性的iframeQ提交时可以制定targetiframe的name。对于IE4+Q你可以用高度ؓ0的frame来作Q例子，

test6.htm
===================
<script>
  window.showModalDialog("test7.htm")
</script>

test7.htm
===================
if(window.location.search) alert(window.location.search)
<frameset rows="0,*">
  <frame src="about:blank">
  <frame src="test8.htm">
</frameset>

test8.htm
===================
<form target="_self" method="get">
<input name=txt value="test">
<input type=submit>
</form>
<script>
if(window.location.search) alert(window.location.search)
</script>
2,可以通过http://servername/virtualdirname/test.htm?name=mxh方式直接向对话框传递参数吗Q?
{案是不能。但在frame里是可以的?

Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q?
另外Q?
http://www.csdn.net/
本h整理

问：
1.模态窗口的打开
2.模态窗口的关闭
3.模态窗口的传递参数?
4.其他。。。?

hgknight(江雨.net){：
1.window.showModalDialog("DialogPage.aspx","newwin","dialogHeight: 200px; dialogWidth: 150px; dialogTop: 458px; dialogLeft: 166px; edge: Raised; center: Yes; help: Yes; resizable: Yes; status: Yes;");

2.window.close();

3.传?
ParentPage.aspx:
window.showModalDialog("DialogPage.aspx?para1=aaa¶2=bbb");

DialogPage.aspx:
string str1=Request.QueryString["para1"].toString();
string str2=Request.QueryString["para2"].toString();

q回?
DialogPage.aspx:
window.returnvalue="aaa";

ParentPage.aspx:
var str=window.showModalDialog("DialogPage.aspx");

4.
aspx面在showmodeldialog情况下ؓ什么一提交重新打开一个页?
showmodaldialog打开的页面中?lt;head></head>之间加入一行：<base target="_self">
Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－Q－
snowjin78(方圆)
以前Q我也问q此c问题，现把收获贴如下（当然好多东西都是别h告诉我的Q：
最好不要用Response.Write(  "  <script....  </script  >  ")q样的方法注册客L脚本Q而应该用Page.RegisterStartupScript或Page.RegisterClientScriptBlockҎ来注?
Page.RegisterClientScriptBlockQ ?
在  Page  对象的   ?lt;form  runat=  server  >  元素的开始标记后立即发出客户端脚本 ?
Page.RegisterStartupScript:  
该方法在  Page  对象的   ?lt;form  runat=  server  >  元素的结束标C前发脚本

客户端代码有两个问题Q第一是把window写成了WindowQjavascript是严格区分大写的，用Window是肯定会出错的；W二个问题是讄对话框的宽度用dialogWidthQ高度用dialogHeightQ而不是height和width。！

q里分三部分来介l?jFreeChart 。第一部分介绍jFreeChart产生
囑Ş的流E及相关的重要的c；W二部分介绍四种常用的报表图Q饼图、柱状图、折U图、时间序列图Q；W三部分
介绍在图形中增加Item Lable ?
jFreeChart 的版本是jfreechart-1.0.0-pre2(1)

[b]一、jFreeChart产生囑Ş的流E[/b]
   创徏一个数据源QdatasetQ来包含要在图形中昄的数?创徏一?JFreeChart 对象来代表要昄的图?br />   把图形输?br />   重要的类和接口：
   org.jfree.data.general.Dataset  所有数据源c都要实现的接口
   org.jfree.chart.ChartFactory    由它来?JFreeChart 对象
   org.jfree.chart.JFreeChart    所有对囑Ş的调整都是通过它噢Q！
   org.jfree.chart.plot.Plot    通过JFreeChart 对象获得它，然后再通过它对囑Ş外部部分Q例Q坐标uQ调?br />                                注意Q它有很多子c，一般都下嗍造型到它的子c！
   org.jfree.chart.renderer.AbstractRenderer     通过JFreeChart 对象获得它，然后再通过它对囑Ş内部部分
                                                Q例Q折U的cdQ调整。同P针对不同cd的报表图Q它?br />                                                着不同的子cd玎ͼ在下面我们简U它?Renderer
   下面我们l合不同cd的图形来具体分析q个程?br />  
[b]二、饼图[/b]
   饼图的dataset 一般是用PieDataset 接口Q具体实现类?DefaultPieDataset
   1、创Z个数据源QdatasetQ：
    private static PieDataset createDataset()
    {
        DefaultPieDataset defaultpiedataset = new DefaultPieDataset(); //注意是DefaultPieDatasetQ！
        defaultpiedataset.setValue("One", new Double(43.200000000000003D));
        defaultpiedataset.setValue("Two", new Double(10D));
        defaultpiedataset.setValue("Three", new Double(27.5D));
        defaultpiedataset.setValue("Four", new Double(17.5D));
        return defaultpiedataset;
    }
   2、由ChartFactory  产生 JFreeChart 对象
    private static JFreeChart createChart(PieDataset piedataset)
    {
        JFreeChart jfreechart = ChartFactory.createPieChart("Pie Chart Demo 1",  //囑Ş标题名称
                                                              piedataset,   // dataset
                                                              true,      // legend?
                                                              true,     // tooltips?
                                                              false);  //URLs?
        PiePlot pieplot = (PiePlot)jfreechart.getPlot();  //通过JFreeChart 对象获得 plotQPiePlotQ！
        pieplot.setNoDataMessage("No data available");    // 没有数据的时候显C的内容
        return jfreechart;
    }
    一些重要的ҎQ?br />    pieplot.setExplodePercent(0,0.3D) //把Lable ?One" 的那一块”挖“出?0%   
   3、输出略 
  
[b]三、柱状图[/b]
   q囄dataset 一般是用CatagoryDataset接口(具体实现cLDefaultCategoryDataset),也会?IntervalXYDataset
   接口
   1、创Z个数据源QdatasetQ：
    private static CategoryDataset createDataset()
    {
        String series1 = "First";
        String series2 = "Second";
        String series3 = "Third";
        String category1 = "Category 1";
        String category2 = "Category 2";
        String category3 = "Category 3";
        String category4 = "Category 4";
        String category5 = "Category 5";
        DefaultCategoryDataset defaultcategorydataset = new DefaultCategoryDataset();
        defaultcategorydataset.addValue(1.0D, series1, category1);
        defaultcategorydataset.addValue(4D, series1, category2);
        defaultcategorydataset.addValue(3D, series1, category3);
        defaultcategorydataset.addValue(5D, series1, category4);
        defaultcategorydataset.addValue(5D, series1, category5);
       
        defaultcategorydataset.addValue(5D, series2, category1);
        defaultcategorydataset.addValue(7D, series2, category2);
        defaultcategorydataset.addValue(6D, series2, category3);
        defaultcategorydataset.addValue(8D, series2, category4);
        defaultcategorydataset.addValue(4D, series2, category5);
       
        defaultcategorydataset.addValue(4D, series3, category1);
        defaultcategorydataset.addValue(3D, series3, category2);
        defaultcategorydataset.addValue(2D, series3, category3);
        defaultcategorydataset.addValue(3D, series3, category4);
        defaultcategorydataset.addValue(6D, series3, category5);
        return defaultcategorydataset;
    }
   2、由ChartFactory  产生 JFreeChart 对象   
    private static JFreeChart createChart(CategoryDataset categorydataset)
    {
        JFreeChart jfreechart = ChartFactory.createBarChart("Bar Chart Demo", //囑Ş标题名称

        //下面两行使纵坐标的最单位格为整?br />        NumberAxis numberaxis = (NumberAxis)categoryplot.getRangeAxis();
        numberaxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());
        BarRenderer barrenderer = (BarRenderer)categoryplot.getRenderer(); //获得renderer 注意q里是下嗍造型
                                                                             到BarRendererQ！
        barrenderer.setDrawBarOutline(false); // Bar的外轮廓U不?br />        GradientPaint gradientpaint = new GradientPaint(0.0F, 0.0F, Color.blue,
        0.0F, 0.0F, new Color(0, 0, 64));   //讑֮特定颜色
        GradientPaint gradientpaint1 = new GradientPaint(0.0F, 0.0F, Color.green,
        0.0F, 0.0F, new Color(0, 64, 0));
        GradientPaint gradientpaint2 = new GradientPaint(0.0F, 0.0F, Color.red,
        0.0F, 0.0F, new Color(64, 0, 0));
        barrenderer.setSeriesPaint(0, gradientpaint); //lseries1 Bar讑֮上面定义的颜?br />        barrenderer.setSeriesPaint(1, gradientpaint1); //lseries2 Bar 讑֮上面定义的颜?br />        barrenderer.setSeriesPaint(2, gradientpaint2); //lseries3 Bar 讑֮上面定义的颜?br />        CategoryAxis categoryaxis = categoryplot.getDomainAxis();  //横u上的 Lable 45度倾斜
        categoryaxis.setCategoryLabelPositions(CategoryLabelPositions.UP_45);       
        return jfreechart;
    } 
    一些重要的ҎQ（增加一块标讎ͼ
        IntervalMarker intervalmarker = new IntervalMarker(4.5D, 7.5D);
        intervalmarker.setLabel("Target Range");
        intervalmarker.setLabelFont(new Font("SansSerif", 2, 11));
        intervalmarker.setLabelAnchor(RectangleAnchor.LEFT);
        intervalmarker.setLabelTextAnchor(TextAnchor.CENTER_LEFT);
        intervalmarker.setPaint(new Color(222, 222, 255, 128));
        categoryplot.addRangeMarker(intervalmarker, Layer.BACKGROUND);   
       
[b]四、折U图[/b]
   折线囄dataset 两种CatagoryDataset接口(具体实现cLDefaultCategoryDataset),XYDataset 接口
   1、CatagoryDataset接口Q       ?
   A、创Z个数据源QdatasetQ：
    private static CategoryDataset createDataset()
    {

        timeseriescollection.setDomainIsPointsInTime(true); //domain轴上的刻度点代表的是旉点而不是时间段
        return timeseriescollection;
    }
   2、由ChartFactory  产生 JFreeChart 对象
    private static JFreeChart createChart(XYDataset xydataset)
    {
        JFreeChart jfreechart = ChartFactory.createTimeSeriesChart("Legal & General Unit Trust Prices",
                                                                   "Date",

        DateAxis dateaxis = (DateAxis)xyplot.getDomainAxis(); //对domain 轴上日期昄格式定义
        dateaxis.setDateFormatOverride(new SimpleDateFormat("MMM-yyyy"));
        return jfreechart;
    } 
       一些重要的ҎQ?br />     A、增加标记线Q?
        xyplot.addRangeMarker(new ValueMarker(550D)); //数Du
        Quarter quarter = new Quarter(2, 2002);
        xyplot.addDomainMarker(new ValueMarker(quarter.getMiddleMillisecond()));  //旉?br />     B、数据点的调?br />        XYLineAndShapeRenderer xylineandshaperenderer = (XYLineAndShapeRenderer)xyplot.getRenderer();
        xylineandshaperenderer.setDefaultShapesVisible(true);  //数据点可?br />        xylineandshaperenderer.setSeriesFillPaint(0, Color.red);  //数据点填充ؓU色
        xylineandshaperenderer.setSeriesFillPaint(1, Color.white);  //数据点填充ؓ白色
        xylineandshaperenderer.setUseFillPaint(true);    //应用
     C、^均值曲U?
       q个曲线有什么用呢？很简单的例子Q这里有一个以半年每天为单位的数据l制的曲U，我们想看看以月ؓ单位数据
       的变化，q时可以用到它了?
        TimeSeries timeseries = createEURTimeSeries();  //是以半q每天ؓ单位的数?br />        TimeSeries timeseries1 = MovingAverage.createMovingAverage(timeseries,
                                                                   "30 day moving average",
                                                                   30, //30天ؓ一个周?br />                                                                   30); //最开始的30天蟩q?br />        TimeSeriesCollection timeseriescollection = new TimeSeriesCollection();
        timeseriescollection.addSeries(timeseries);
        timeseriescollection.addSeries(timeseries1);
        return timeseriescollection;
    
[b]六、ȝ一下[/b]
                           dataset                          plot                    renderer                      
  饼图           PieDatasetQDefaultPieDatasetQ         ?PiePlot                    ------

  旉序列图   ?XYDataset QTimeSeriesCollectionQ       ?XYPlot                XYLineAndShapeRenderer
  q里只是一些常用的ҎQ具体还是看API ,主要的类ȝ如下Q?br />JFreeChart:生成图表的中间存攄?/p>

CategoryDataSet:图表的数据，主要包含行数据（String[] cdQ，列数?String[] cdQ和L据                  ?(double[][]cdQ。一般来说简单的图表L据都是double[1][]cd的?/div>
ChartFactory: 工厂c，提供多种Ҏ生成多达30多种图表Q用得比较多的是BarChart(q?,LineChart             Q折U图Q，PieChartQ饼状图Q。工厂方法看h比较l一QcreatXXXChart(图表标题Q            ?行标题，列标题，L据（CategoryDataSetQ?
ChartUtities: 公用c，提供各种持久保存图表数据的方法，比如saveChartAsJPEG(FileQ                           ?JFreeChart,width,height)
其他q有一些渲染类Q主要是用来化图表界面Q调整和优化昄风格{?/div>
ȝ来说q不错，比jasperReport要简单，上手很快Q图表效果也q不错，用来做普通数据图表够了



[b]七、Item Lable[/b]
   q里以柱状图Z说明Q具体来说就是在每个q上显C它的数据，具体有下面内容：
   A、 Item Lable 可见
   B、调?Item Lable 的颜艌Ӏ字体等
   C、调?Item Lable 的位|?br />   D、定?Item Lable 的内?br />   1、分配一?Lable Generator l?renderer
      BarRenderer barrenderer = (BarRenderer)categoryplot.getRenderer();
      GategoryLableGenerator generator =new StandardGategoryLableGenerator(
           "{2}", new DecimalFormat("0.00")    //调整昄的数字和字符格式
      );
      barrenderer.setLableGenerator(generator);
   2、 Item Lable 可见
      barrenderer.setItemLableVisible(true);
   3、调?Item Lable 的颜艌Ӏ字体等
      barrenderer.setItemLablePaint(Color.red);
      barrenderer.setItemLableFont(new Font("SansSerif",Font.PLAIN,10));
   4、调?Item Lable 的位|?br />      q里涉及C个新的对?ItemLablePosition , ItemLablePosition的构造函数有两个或四个参?br />      public ItemLabelPosition(ItemLabelAnchor itemLabelAnchor,
                         org.jfree.ui.TextAnchor textAnchor,
                         org.jfree.ui.TextAnchor rotationAnchor,
                         double angle)
      itemLabelAnchor - Item Lable 的位|?Q最重要的！Q）
      textAnchor - Item Lable里包含的正文相对于Item Lable 的位|?br />      rotationAnchor - Item Lable里包含的正文旋{的位|?br />      angle - 旋{的角?br />      ItemLabelPosition itemlabelposition = new ItemLabelPosition(ItemLabelAnchor.INSIDE12,
                                                      TextAnchor.CENTER_RIGHT,
                                                      TextAnchor.CENTER_RIGHT,
                                                      -1.57D);
      barrenderer.setPositiveItemLabelPosition(itemlabelposition);
   q样可以每个柱状上昄它的数据了，当然可以定制 Item Lable 的内容，比如 Item Lable text 过100的才
   昄Q这样就需要定制自qc，它要实现GategoryLableGenerator 接口Q实现generateItemLable()Ҏ?/p>

试用了一下FCKeditor,Ҏ|上的文章小l一下：
1.下蝲
FCKeditor.java 2.3 (FCKeditot for java)
FCKeditor 2.2 (FCKeditor基本文g)

2.建立目:tomcat/webapps/TestFCKeditor.

3.FCKeditor2.2解压~?整个目录FCKeditor复制到项目的根目录下Q?br />目录l构为：tomcat/webapps/TestFCKeditor/FCKeditor
然后FCKeditor-2.3.zipQjavaQ压~包中\web\WEB-INF\lib\目录下的两个jar文g拷到目的\WEB-INF\lib\目录下。把其中的src目录下的FCKeditor.tld文gcopy到TestFCKedit/FCKeitor/WEB-INF/?/p>

4.FCKeditor-2.3.zip压羃包中\web\WEB-INF\目录下的web.xml文g合ƈ到项目的\WEB-INF\目录下的web.xml文g中?/p>

5. 修改合ƈ后的web.xml文gQ将名ؓSimpleUploader的Servlet的enabled参数值改为trueQ?br />以允怸传功能，Connector Servlet的baseDir参数值用于设|上传文件存攄位置?br />d标签定义:

9.打开/FCKeditor/fckconfig.js
修改 FCKConfig.DefaultLanguage = 'zh-cn' ;
把FCKConfig.LinkBrowserURL{的值替换成以下内容Q?br />FCKConfig.LinkBrowserURL

q段旉较闲,研究了一番dwr.发现dwr实现的AJAX有些地方实很是先进.比如动态生成javascript代码;隐藏的http协议;javascript于java代码交互的是javascript对象(或字W串){?
以下是我临时译的一些东?本来惛_?发现dwr实在是简?随便写?英文居差,C?

1、DWR: Easy AJAX for JAVA

作ؓ一个java open source library,DWR可以帮助开发h员完成应用AJAX技术的webE序。它可以让浏览器上的javascriptҎ调用q行在web服务器上javaҎ?

DWR主要׃部门l成。javascript与web服务器通信q更新web；q行在web服务器的Servlet处理hq把响应发回览器?

DWR采用新颖的方法实CAJAX(本来也没有确切的定义)Q在java代码基础上动态的生成javascript代码。web开发者可以直接调用这些javascript代码Q然而真正的代码是运行在web服务器上的java code。出与安全考虑Q开发者必配|哪些java class暴露lDWR.(dwr.xml)

q种?java到javascript)调用机制l用户一U感觉，好象常规的RPC机制Q或RMI or SOAP.但是它运行在web上，不需要Q何浏览器插g?

DWR不认为浏览器和web服务器之间协议重要，把系l界面放在首位。最大挑战是java method call的同步特征与ajax异步Ҏ之间的矛盾。在异步模型里，l果只有在方法结束后才有效。DWR解决了这个问题，把回调函数当成参Cl方法，处理完成后，自动调用回调Ҏ?

q个图表昄了，通过javascript事gQDWR能改变select的内容，当然q些内容由java代码q回?javascript函数Data.getOptions(populateList)由DWR动态生成，q个函数会调用java class DatacȝҎ。DWR处理如何q程调用Q包括{换所有的参数和返回的l果Qjavascript\javaQ。javaҎ执行完后Q执行回调方法populateList。在整个q程中我们就惛_用本地的Ҏ一栗?

2、Getting Started

废话说Q试试就ok了?
web.xml

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app id="dwr">
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>dwr-invoker</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
</web-app>

dwr.xml 与web.xml同目?
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN" "http://www.getahead.ltd.uk/dwr/dwr10.dtd">
<dwr>
<allow>
<create creator="new" javascript="JDate">
<param name="class" value="/java.util.Date"/>
</create>
</allow>
</dwr>

index.html
<html>
<head>
<title>DWR - Test Home</title>
<script type='text/javascript' src="/dwr/interface/JDate.js"></script>
<script type='text/javascript' src="/dwr/engine.js"></script>
<script>
function init(){
JDate.getYear(load);
}
function load(data){
alert(data+1900+'q?)
}
</script>
</head>
<body onload="init()">
</body>
</html>

dwr.jar 下蝲放lib?

完了Q什么，够了Q就q些。访问ok!
3、Examples
http://www.aboutmyhealth.org/ q不是Google Suggest?ok.
4、源码浅?
dwr的设计很象webwork2的设?隐藏http协议,扩展性，兼容性及强?

通过研究uk.ltd.getahead.dwr.DWRServletq个servlet来研I下dwr到底是如何工作滴?

java代码:  

web.xml配置
<servlet>
    <servlet-name>dwr-invoker</servlet-name>
    <servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>dwr-invoker</servlet-name>
    <url-pattern>/dwr/*</url-pattern>
</servlet-mapping>


q样所有的/dwr/*所有请求都p个servlet来处理，它到底处理了些什么能。我们还以上面最单的例子来看?
1?web服务器启动，DWRServlet init()Ҏ调用Qinit主要做了以下工作?
讄日志U别、实例化DWR用到的单例类Q这些类在jvm中只有一个实例对象）、读去配|文Ӟ包括dwr.jar包中的dwr.xml,WEB-INF/dwr.xml. config*.xmlQ?
2、请求处?
DWRServlet.doGet, doPostҎ都调用processor.handle(req, resp)Ҏ处理。Processor对象在init()Ҏ中已l初始化了?
java代码:  

public void handle(HttpServletRequest req, HttpServletResponse resp)
        throws IOException
    {
        String pathinfo = req.getPathInfo();
        if(pathinfo == null || pathinfo.length() == 0 || pathinfo.equals("/"))
        {
            resp.sendRedirect(req.getContextPath() + req.getServletPath() + '/' + "index.html");
        } else
        if(pathinfo != null && pathinfo.equalsIgnoreCase("/index.html"))
        {
            doIndex(req, resp);
        } else
        if(pathinfo != null && pathinfo.startsWith("/test/"))
        {
            doTest(req, resp);
        } else
        if(pathinfo != null && pathinfo.equalsIgnoreCase("/engine.js"))
        {
            doFile(resp, "engine.js", "text/javascript");
        } else
        if(pathinfo != null && pathinfo.equalsIgnoreCase("/util.js"))
        {
            doFile(resp, "util.js", "text/javascript");
        } else
        if(pathinfo != null && pathinfo.equalsIgnoreCase("/deprecated.js"))
        {
            doFile(resp, "deprecated.js", "text/javascript");
        } else
        if(pathinfo != null && pathinfo.startsWith("/interface/"))
        {
            doInterface(req, resp);
        } else
        if(pathinfo != null && pathinfo.startsWith("/exec"))
        {
            doExec(req, resp);
        } else
        {
            log.warn("Page not found. In debug/test mode try viewing /[WEB-APP]/dwr/");
            resp.sendError(404);
        }
    }


哦。这些恍然大悟。dwr/*处理的请求也p几种?
Q?Qdwr/index.htmlQdwr/test/q种只能在debug模式下用，调试用?
dwr/engine.jsQdwr/util.jsQdwr/deprecated.js当这个请求到达，从dwr.jar包中d文g，响应回去。（重复h有缓存）
Q?Q当dwr/interface/q种h到来Q（例如我们在index.html中的 <script type='text/javascript' src="/dwr/interface/JDate.js"></script>QDWR做一件伟大的事。把我们在WEB-INF/dwr.xml中的
<create creator="new" javascript="JDate">
<param name="class" value="/java.util.Date"/>
</create>
java.util.Date转化为javascript函数?
http://localhost:port/simpledwr/dwr/interface/JDate.js看看吧?
l节也比较简单，通过java反射Q把Ҏ都写成javascript特定的方法。（我觉得这些{换可以放到缓存里Q下ơ调用没必要再生成一遍，不知道作者ؓ什么没q样做）?
Q?Qdwr/exec
javascript调用Ҏ时发送这U请求，可能是XMLHttpRequest或IFrame发送?
当然Qjavascript调用的方法签名与java代码一_包括参数Q还有javascript的回调方法也传到了服务器端，在服务器端很Ҏ实现。回调方法的java的执行结?q回cM <script>callMethod(l果)<script>的javascript字符?在浏览器执行。哈Q一切就q么单，巧妙?

dwr的设计构思很是y妙?
W一、把javac{化ؓjavascriptcȝdwr自动完成Q只需单的配置?
W二、应用v来极其简单。开发者不要该服务器代码就可以集成?
W三、容易测试。和webwork一P隐藏的http协议?
W四、及强扩展性。例如与spring集成Q只需修改一点代码?
W五、性能。就我与jason,{简单比较，dwr性能可能是最好的?/span>
