if(top.document.frames["mainIframe"].document && window.document.body.scrollHeight=="0"){
parent.document.getElementById("mainIframe").style.height=500;
}
}
function page(page){
document.getElementById("mainIframe").src=page;
}
造成IE,FireFox,Opera中Iframe顯示差異原因在于
1.iframe在FireFox中取法為parent.document.getElementById("mainIframe").contentDocument,而在ie,opera中為parent.document.getElementById("mainIframe").document
2.當頁面無滾動時，window.document.body.scrollHeight在IE中能取到，fireFox和Opera中取不到。

主要通過javascript實現，理解IE的DOM結構，并調用元素的固定方法，可以實現表單元素的動態增刪。
下面是部分代碼。
<html>
<head>
<script language="javascript">
function add(){
//取得表格
var table = document.getElementById("table1");
//取得行數;
var num = table.rows.length;
//增加一行
var newrow1 = table.insertRow(num-1);
var cell1 = newrow1.insertCell();
var cell2 = newrow1.insertCell();
var cell3 = newrow1.insertCell();
var cell4 = newrow1.insertCell();
//增加行元素
var inputcell2 = document.createElement("<input size='32' name=''>");
cell2.appendChild(inputcell2);
var inputcell4_1 = document.createElement("<input size='32' name=''>");
var inputcell4_2 = document.createElement("<input type='button' value='刪除元素'onClick='del(this);'/>");
cell4.appendChild(inputcell4_1);
cell4.appendChild(inputcell4_2);
//刷新標簽顯示
frash();
}
function del(obj){
//取得按鈕所在行
var i = obj.parentNode.parentNode.rowIndex;
var tab = document.getElementById("table1");
//刪除按鈕所在行
tab.deleteRow(i-1);
frash();
}
function frash(){
var table = document.getElementById("table1");
var num = table.rows.length;
//計算動態元素個數
var n = num-2;
for(i=1;i<=n;i++){
//設置標簽值
table.rows[i].cells[0].innerText="元素"+i+"屬性A";
//設置屬性值
table.rows[i].cells[1].childNodes[0].setAttribute("name","ysa"+i);
table.rows[i].cells[2].innerText="元素"+i+"屬性B";
table.rows[i].cells[3].childNodes[0].setAttribute("name","ysb"+i);

頁面打印通常直接調用IE中打印命令，并通過class控制打印范圍。當頁面文件內容過多，無法完整打印時，可以通過javascript控制縮放實現完整打印。
下面是部分代碼。

思路是把表單類型設置為enctype="multipart/form-data"，其他表單中文本數據通過javascript處理，附加在action后面，后臺通過request.getParameter()取得。上傳文件調用commons-fileupload.jar中方法。
下面是部分代碼。
<form name="ajform" action="/da.do" method="post" enctype="multipart/form-data">
<tr><td><input name="a" value=""></td></tr>
<tr><td><input name="b" type="file"></td></tr>
<tr><td><a href="#" onclick="checksubmit();">提交</a></td></tr>
</form>
<script language="javascript">
function checksubmit(){
var value = "/da.do?formAction=save";
value = value+"&a="+ window.document.getElementById("a").value;
window.document.ajform.action=value;
window.document.ajform.submit();
}
</script>
String a = request.getParameter("a");
try {
//文件上傳目錄“/file/wj”
String filepath= request.getSession().getServletContext().getRealPath("/")+"file"+File.separator+"wj";
//文件上傳臨時目錄“/file/temp”
String tempPath = request.getSession().getServletContext().getRealPath("/")+"file"+File.separator+"temp";
File dir = new File(filepath);
//建立目錄
if(!dir.exists()){
dir.mkdirs();
}
File dir1 = new File(tempPath);
if(!dir1.exists()){
dir1.mkdirs();
}
DiskFileUpload fu = new DiskFileUpload();
//設置最大文件尺寸，這里是10MB
fu.setSizeMax(10485760);
//設置緩沖區大小，這里是4kb
fu.setSizeThreshold(4096);
//設置臨時目錄：
fu.setRepositoryPath(tempPath);
List fileItems = fu.parseRequest(request);
Iterator iter = fileItems.iterator();
while (iter.hasNext()) {
FileItem item = (FileItem) iter.next();
String fileName = item.getName();
//判斷是否為文件
if(fileName!=null){
//取文件名
String name = fileName.substring(fileName.lastIndexOf(File.separator)+1);
if(fileName!=null&& !fileName.equals("")) {
File file = new File(filepath+File.separator+name);
//上傳文件
item.write(file);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}

1。EJB打包
<?xml version="1.0"?>
<project name="jartest" default="jar" basedir=".">
<property name="build.dir" value="${basedir}/build" />
<property name="build.classes.dir" value="${build.dir}/classes" />
<target name="jar" description="打包成Jar">
<jar jarfile="${basedir}/ejbfile.jar">
<fileset dir="${build.classes.dir}">
<include name="**/*.class" />
</fileset>
<metainf dir="${basedir}/META-INF ">
<include name="**" />
</metainf>
</jar>
</target>
</project>
2。web應用打包
<?xml version="1.0"?>
<project name="wartest" default="war" basedir=".">
<target name="war" description="創建WEB發布包">
<war warfile="${basedir}/EJBTest.war" webxml="${basedir}/WEB-INF/web.xml">
<fileset dir="${basedir}">
<include name="**"/>
<exclude name="build.xml" />
<exclude name="/WEB-INF/web.xml" />
</fileset>
</war>
</target>
</project>
1.web.xml中配置Spring的servlet和servlet-mapping
???<servlet>
??????? <servlet-name>example</servlet-name>
??????? <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
????????<init-param>?
????????????<param-name>contextConfigLocation</param-name>?
????????????<param-value>/WEB-INF/application-servlet.xml</param-value>?
????????</init-param>?
????????<load-on-startup>1</load-on-startup>
??? </servlet>
??? <servlet-mapping>
??????? <servlet-name>example</servlet-name>
??????? <url-pattern>*.do</url-pattern>
??? </servlet-mapping>
2.配置spring配置文件application-servlet.xml
???<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
?????<property name="prefix">
?????????<value>/page/</value>
?????</property>
?????<property name="suffix">
?????????<value>.jsp</value>
?????</property>
???</bean>
???<bean id="urlMapping"?class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
????????<property name="mappings">
????????????<props>
????????????????<prop key="/login.do">loginAction</prop>
????????????</props>
????????</property>
???</bean>
???<bean id="loginAction" class="loginAction">
????????<property name="commandClass">
????????????<value>?LoginActionVo??</value>
????????</property>
????????<property name="formView">
????????????<value>login</value>
????????</property>
????????<property name="sessionForm">
????????????<value>true</value>
????????</property>
????????<property name="serviceLocator">
????????????<ref bean="servicelocator" />
????????</property>
?</bean>
3.新建類繼承SimpleFormController﹐並複寫protected Object formBackingObject(HttpServletRequest request)?和?protected ModelAndView onSubmit(HttpServletRequest request,?HttpServletResponse response,
?Object cmd, BindException ex)。常用結構為
???protected Object formBackingObject(HttpServletRequest request){
??????LoginActionVo??loginActionVo?? = new LoginActionVo?();
??????request.setAttribute("?loginActionVo",?loginActionVo);
??????return loginActionVo;
???}
???protected ModelAndView onSubmit(HttpServletRequest request,?HttpServletResponse response,
???????Object cmd, BindException ex){
??????LoginActionVo??loginActionVo =(LoginActionVo)cmd;
??????Map map = new HashMap();
?????map.put("?loginActionVo",?loginActionVo);
?????request.getSession().setAttribute(this.getFormSessionAttributeName(),?loginActionVo);
?????return new ModelAndView("login",map);
? }
4.將jsp頁面參數和VO進行綁定。綁定的方法為頁面元素name和VO對象對應﹐當進行深層次的綁定時﹐要注意﹐在變量的get方法中進行初始化。在servlet2.4容器中可以不用c:out標籤
輸入框綁定﹕<input name="user.name"? value = "<c:out value="${loginActionVo.user.name}"/>" type="text" disabled="disabled"? size="14" maxlength="14" /></td>
VO為﹕
?public class loginActionVo{
????private User user;
????public?User getUser(User user){
??????if( user == null){
?????????user = new User();
??????}
??????return user;
???}
?}
???
以SimpleFormController為例
1。spring 接收一個請求後首先會判斷"get"還是"post"方法
2。1 "get"方法時
?????????2。1。1 首先創建一個command對象﹐通過調用AbstractFormController的formBackingObject方法得到﹐通常是一個pojo﹐根據name用來和提交的數據綁定。
????????? 2。1。2 然後會創建一個BindException對象﹐裡面包括command對象﹐和其他一些屬性。
???????????2。1。3 判斷sessionForm 屬性﹐默認為false。如果為true﹐就會把command對象對象保存在session裡???? 面。session中key為類名+".FORM." + command對象名。可以通過request.getSession().getAttribute(this.getFormSessionAttributeName(request));得到command對象。
??????
???2。1。4 調用AbstractFormController的referenceData方法。這個方法默認為空﹐可以復寫來初始化頁面參數。
2。1。5 返回ModelAndView對象﹐返回formview頁面。
2 。2 “post”方法時
???2。2。1 首先得到command對象,如果SessionForm = false﹐調用formBackingObjectde創建
?????????????????????如果SessionForm = true,從request.getSession中得到原command對象﹐然後將command對象從
?????????????????????Session中刪除。
? 2。2。2? 然後會創建一個ServletRequestDataBinder對象﹐裡面包括command對象﹐和其他一些屬性。
???????????????????這個過程將調用initBinder()﹔可以複寫這個方法初始化數據。
?2。2。3 調用processFormSubmission(HttpServletRequest request, HttpServletResponse response, Object command,? BindException errors)。有錯誤時返回formview頁面﹐否則進入successview頁面。這個過程將調用onSubmit(Object command)﹐必須複寫這個方法放入業務邏輯。
