"你可以主觀地討厭它，但你永遠(yuǎn)不能忽略它。" -- aw
作為一個技術(shù)人員,你可以因?yàn)闈嶑?
而去討厭M$的霸權(quán)行徑,QQ的抄襲主義,
但是你卻絕對不能無視它的存在.
--- 這是現(xiàn)在自己的想法,以前曾經(jīng)很bs qq的抄襲,
但是你不能否認(rèn)它抄的很好,idea雖然是你的,但是你發(fā)揮的沒有它發(fā)揮的好.
以前我也是google的fan,但是現(xiàn)在我用的google的很多服務(wù)都慢慢被QQ侵蝕了.
GOOGLE是一個很偉大的公司,但是他的本地化..實(shí)在是太慢了..

官方的extjs3.0包里面沒有提供ext.jsb文件.
于是去官方論壇問了下, 3.0他們提供的是jsb2,基于json的.
現(xiàn)在spket還不支持。
有人重新做了個臨時的3.0的jsb文件,如附件。
用法:
1.下載后放到3.0的src目錄下 (一定要切記...我就是一時糊涂放錯了...在官方那鬧了笑話 -.-!!)
2.然后在skpet中如下圖設(shè)置:
3.設(shè)置為默認(rèn)profile
4.設(shè)置完后,關(guān)閉所有標(biāo)簽頁 ,重啟skpet就ok了.
5.提示效果如下圖:
關(guān)于spket和extjs的ide,請參考:http://www.javaeye.com/topic/161161
09.07.23更新:
skpet出新版本了,支持extjs的jsb2.官方下載:
Spket IDE 1.6.17 released - 22 July 2009
http://spket.com/
09.08.11更新
spket1.6.16的破解包,覆蓋即可.
下載地址見http://atian25.javaeye.com/blog/426824文末
09.08.12更新:
ext.jsb2已經(jīng)包含在官方的壓縮包里面了.
或者你可以從我另一篇blog中下載:http://atian25.javaeye.com/admin/blogs/445480
注意:
1.該jsb2文件需要spket1.6.17
2.放置目錄為根目錄而不是src目錄 (跟前面的jsb文件不同)

很實(shí)在的一個需求,就是我們只需要extjs的一部分功能,不想把整個類庫都包含進(jìn)來.
所以讓我們來定制extjs吧~
1. ExtJS 1.1.1或2.3.0
可以用官方的在線工具來定制:http://extjs.com/products/extjs/build/
使用教程:
e文:http://extjs.com/learn/Tutorial:Building_Ext_From_Source
中文:http://extjs.org.cn/node/364
2. EXTJS 3.0
現(xiàn)在還沒有在線版,可以通過以下方法來自己定制:
1. 下載Ext 3.0.0 SDK. http://extjs.com/products/extjs/download.php?dl=extjs3
2. 下載JSBuilder2. http://extjs.com/products/jsbuilder/ (或者看文末的附件)
3. 下載Ext 3.0.0的ext.jsb2文件 http://extjs.com/forum/showthread.php?p=354473 (或者看文末的附件)
4. 把JSBuilder2解壓jar到extjs根目錄下,ext.jsb2也放到根目錄下
5. 用你的文本編輯器編輯ext.jsb2文件,僅保留你需要的模塊
6. jsb2文件中的deployDir: 'ext-3.0.0-build'表示相對輸出目錄
7. cmd,切換到ext根目錄下,執(zhí)行:
G:\Learning\Web\Javascript\ExtJS\ext-3.0.0> java -jar "JSBuilder2.jar" -p ./ext.jsb2 -d ./
8.等待刷屏完畢后去你在jsb2中指定的目錄下找輸出吧.
3.試驗(yàn)
一個試驗(yàn)的例子,僅包含Tree組件,如附件
1) resource部分未作過濾
2) 注意依賴關(guān)系,如
name: 'Trees',
file: 'pkgs/pkg-tree.js',
isDebug: true,
pkgs: ['pkgs/cmp-foundation.js']
3)輸出的文件樹如下:
adapter\
|--ext\
|----ext-base.js
|----ext-base-debug.js
pkgs\
|--cmp-foundation.js
|--ext-foundation.js
|--pkg-tree.js
|--cmp-foundation-debug.js
|--ext-foundation-debug.js
|--pkg-tree-debug.js
resources\

Changes, Additions (roughly organized alphabetically)
1.Ext
- 新增:
- iterate 方法 - 遍歷一個數(shù)組或?qū)ο?對每個元素都執(zhí)行指定的函數(shù)
- isNumber 方法 - 判斷傳遞的參數(shù)對象是否是數(shù)字
- isString 方法 - 判斷傳遞的參數(shù)對象是否是字符串
- isBoolean 方法 - 判斷傳遞的參數(shù)對象是否是布爾值
- isDefined 方法 - 判斷傳遞的參數(shù)對象是否已經(jīng)定義
2.Ext.lib.Ajax
-
變更: Ajax responses. The
core adapter file in the Ext.lib.Ajax class has been changed in line
with the W3 XMLHttpRequest specification. The response object which emulates the XHR now has getResponseHeader and getAllResponseHeaders
as f unctions rather than Arrays to keep inline with the real XHR
object. So, anyone who was currenltly examining headers using an Array
(as inherited from YUI via yui-ext) will need to change to use a
function.
3.Ext.Componet
-
新增:
- A Component's Observable events may now be set to bubble up the Component-ownerCt axis.
4.Ext.BoxComponent
-
新增:
- getWidth()
- getHeight()
- getOuterSize()
5.Ext.Button
-
新增:
- Rather than being limited to only positioning buttons in a buttons
configuration, they can now be placed anywhere you please.
你的按鈕現(xiàn)在可以放在任意地方,而不僅限于buttons配置項(xiàng)
- Button現(xiàn)在可以縮放為任意高寬,并且有高級的文字布局。 (Buttons can now scale to any height or width and have advanced text positioning.)
- 新的配置:scale: 'small' , iconAlign : 'left' , arrowAlign : 'right'
-
變更:
- Button現(xiàn)在是一個有效的BoxComponent,可以被布局管理器管理。 (Button is now a valid BoxComponent and can partake in layout management. )
- Button的實(shí)現(xiàn)已經(jīng)完全重寫,所以舊版本時候?qū)懙淖远x樣式/主題需要相應(yīng)的修改。(The markup for buttons is
completely different and will require changes if you had implemented a
custom theme. )
6.Ext.Component
-
新增:
- afterrender事件
-
ref 配置項(xiàng) - establish a named reference for an object an ancestor Container (mitigate dependency on 'id' and Ext.getCmp).
- ptypes - ComponentMgr manages plugins similar to xtypes (use Ext.preg similar to Ext.reg)
- nextSibling
- previousSibling
- getDomPositionEl
7.Ext.ComponentMgr
-
新增:
- isRegistered 方法 - 檢查一個xtype是否已經(jīng)被注冊
8.Ext.Container
9.Ext.data.Reader
-
已過時:
- 推薦使用id, 請用 propertyId 和 idIndex
10.Ext.data.Store
-
新增:
- store xtypes
-
autoDestroy 配置項(xiàng) - 當(dāng)store綁定的component被銷毀的時候,銷毀該Store
- setBaseParam()
-
變更:
- baseParams可以被load方法傳遞的同名參數(shù)所覆蓋。( baseParams may be overwritten by params of same name passed to load() )
-
已過時:
- 不推薦使用 id ,請用 storeId 代替它
- 不推薦使用 loadexception 事件,請用 exception 事件
- SimpleStore 更名為 ArrayStore
11.Ext.Element
-
新增:
- mouseenter事件
- mouseleave事件
-
變更/已過時:
- getAttributeNS() - 已過時,用getAttribute()代替
- autoHeight() - 移除
- alignTo() - 變更參數(shù)"position"
- query() - 新增參數(shù)"unique"
- focus() - 新增參數(shù)"defer"
12.Ext.EventManager
-
變更:
- within() - can now also check if the passed element is the target or related target
13.Ext.form
-
新增:
- 當(dāng)動態(tài)添加Container到FormPanel時,Fields會被添加到BasicForm's的集合中。所以BasicForm's setValues 方法現(xiàn)在可以始終對動態(tài)添加的Fields有效。(When dynamically adding Containers anywhere in a FormPanel, any Fields are now found and added to the BasicForm's Collection. So BasicForm's setValues method will now work consistently with dynamically added Fields.)
-
變更:
14.Ext.grid.GridPanel
-
新增:
-
- columnLines 配置項(xiàng) (boolean) - adds class ' x-grid-with-col-lines'
- Ext.grid.Column
- 用來作為columns參數(shù)傳遞給ColumnModel (Instances of this class are used as columns passed to ColumnModel)
- xtypes可以用來指定一些預(yù)先配置好的renderer(xtypes can be used to specify a preconfigured renderer)
- renderer may be specified in additional ways
- Grid RowEditor Class
- Grid like ListView and ListView.Sorter Classes (譯注:就是一個用DataView+XTemplate來模擬的Grid,輕量)
- Grid BufferedView Class. Buffered GridView enhances performance by
waiting to render rows until they are
visible.(譯注:對大數(shù)據(jù)量的Grid有明顯的性能提升,實(shí)際上就是只渲染用戶可見的列,拖動的時候再渲染其他.官方還有其他的一個擴(kuò)展
Ext.ux.LiveGrid,詳見:http://extjs.com/forum/showthread.php?t=17791)
15.Layouts:
-
新增:
- hbox布局和vbox布局
- 譯注:很有用的兩個布局。但區(qū)域見不能split,不過官方論壇有擴(kuò)展。詳見官方示例
- ToolbarLayout and MenuLayout (internally used by respective classes)
- Layout managers now defer layout of hidden or collapsed child
Components until such time as the child Component becomes visible or
expanded. This avoids size calculation problems in hidden/collapsed
Containers, and removes the need to use hideMode: 'offsets' (may even require that it be removed).
-
新增:
- Menu Overflow. Whenever a menu gets so long that the items won’t
fit the viewable area, it provides the user with an easy UI to scroll
the menu. This feature is turned on by default and can be disabled by
the configuration option
enableScrolling.(譯注:簡單的說就是Menu溢出后的滾動效果,默認(rèn)是開啟該效果,可以通過enableScrolling來配置,詳
見官方示例)
-
變更/已過時:
- Toolbar and Menu are now proper Containers (formerly extended from BoxComponent). 現(xiàn)在Toolbar和Menu都繼承Container
- Breaking change:
MenuItem的ids現(xiàn)在已經(jīng)不是局部變量了,所以你不能在多個menu里面用一個id.建議:用唯一的id或者用itemIds來替代
它。(MenuItem ids are no longer local to their menu but global component
ids. This means that you can't use the same id in multiple menus.
Suggested fix: Use unique ids or switch to using itemIds.)
- As well as Menu being a Container, this also means Menu can be a
regular Component. Menu did not extend BoxComponent before, but was out
on its own. Now, it can behave either as a regular floating Menu, or,
if configured floating: false, it can be used as a usual inline
Component of a
Container.(譯注:簡單的說就是由于menu的繼承改變,現(xiàn)在你可以設(shè)置Menu為浮動的,或者像平常的組件那樣使用它)
- DateItem和ColorItem已經(jīng)被移出,因?yàn)闆]有必要了,現(xiàn)在你可以把任意組件放入menu的items中
- autoWidth() - 變更為autoSize()
17.Ext.MenuButton - 該類已經(jīng)被移除,用SplitButton代替它
18.Ext.StatusBar - 該類已經(jīng)被移出core庫,在3.0final版會有個Ext.ux.StatusBar
19.Ext.Toolbar
-
新增:
- Toolbar Overflow. A menu for items that don’t fit the visible
toolbar area will be created by default and can be disabled with the
configuration option enableOverflow. Items in the menu react with the
same handlers as the toolbar items.(譯注:簡單的說就是Toolbar溢出后的滾動效果詳見官方示例)
-
變更:
- Toolbar and Menu are now proper Containers (formerly extended from BoxComponent).現(xiàn)在Toolbar和Menu都繼承Container
20.Ext.Tooltip
-
新增:
-
delegate option added so one Tooltip can handle multiple child elements of its target based on selection using the delegate config.(譯注:新增的這個屬性很有用,就是通過設(shè)置的selector對某個元素的子對象設(shè)置Tip,在2.0的時候我們經(jīng)常需要的Gird RowTip,CellTip都可以實(shí)現(xiàn)了,不需要實(shí)例化很多Tip對象)
- AnchorTips - Tooltips now support an anchor configuration which
will allow you to bring attention to a particular element or component
with a small callout arrow.(譯注:簡單的說就是箭頭Tip,詳見:http://extjs.com/deploy/dev/examples/simple-widgets/qtips.html)
21.Ext.util.Format
-
新增/變更:
- ellipsis() - "word" parameter added
- focus() - "defer" parameter added
- number() - added
- numberRenderer() - added
- plural() - added
22.Ext.util.Observable
-
新增:
- Ext.util.Observable.observeClass() - Class level observability 類級別的觀察/通知
23.ux's that worked prior to 3.x may need some
tweaking (especially if the ux used private properties). ux's should be
checked they are utilizing the latest preferred techniques and
properties. More notes here. 舊的擴(kuò)展需要相應(yīng)的進(jìn)行修改,詳見:
http://extjs.com/forum/showthread.php?p=338913#post338913
24.CSS. general updates, as well as refactoring to split css into visual and structural files to simplify theming.
26.新增:Ext.FlashComponent (譯注:似乎是用了swfobject,管理swf方便多了,不用adobe那又長又臭的代碼)
28.新增:Writer
29.新增:Ext.Spacer - xtype 'spacer' (for empty box component)
33.新增:Ext.Error
Changes to some example classes: 示例類的修改
(不敢用javaeye編輯器的表格了..自己將就著看吧...)

摘要: http://atian25.javaeye.com/blog/413947
實(shí)際上就是YUI CHART, 具體的文檔可以看: http://developer.yahoo.com/yui/charts/
先上個圖:
代碼如下:
1.定義store
Code highlighting produced by Actipro CodeHighlighter (fr...
閱讀全文
1 var tabs = new Ext.TabPanel({
2 renderTo: 'tabs1',
3 width:450,
4 activeTab: 0,
5 frame:true,
6 defaults:{autoHeight: true},
7 items:[
8 {contentEl:'script', title: 'Short Text'},
9 {contentEl:'markup', title: 'Long Text'}
10 ],
11 initEvents : function(){
12 Ext.TabPanel.superclass.initEvents.call(this);
13 this.on('add', this.onAdd, this, {target: this});
14 this.on('remove', this.onRemove, this, {target: this});
15 this.mon(this.strip, 'mousedown', this.onStripMouseDown, this);
16 this.mon(this.strip, 'contextmenu', this.onStripContextMenu, this);
17 if(this.enableTabScroll){
18 this.mon(this.strip, 'mousewheel', this.onWheel, this);
19 }
20 //ADD:monitor title dbclick
21 this.mon(this.strip,'dblclick',this.onTitleDbClick,this);
22 },
23 //ADD: handler
24 onTitleDbClick:function(e,target,o){
25 var t = this.findTargets(e);
26 if (t.item.fireEvent('beforeclose', t.item) !== false) {
27 t.item.fireEvent('close', t.item);
28 this.remove(t.item);
29 }
30 }
31 });
有一些需求如:
1.一個文件管理的Grid,要求排序的時候,文件夾永遠(yuǎn)在頂部
2.一個顯示成功率的Grid,要求成功數(shù)+失敗數(shù)=0的數(shù)據(jù),不參與排序,永遠(yuǎn)在底部
ExtJs本身并沒有暴露這個接口,所以我們只能自己重寫,如下代碼:
1 var store = new Ext.data.JsonStore({
2 root:'data',
3 fields:[
4 'name',
5 {name:'sucCount',type:'int'},
6 {name:'failCount',type:'int'},
7 {name:'sucRate',type:'float'},
8 {name:'isValidateTest',type:'boolean'},
9 {name:'statType',type:'int'},
10 'testLogIds','bsc','msc','sgsn'
11 ],
12 sortInfo:{field: 'sucRate', direction: 'ASC'},
13 //排序規(guī)則
14 sortData:function(f, direction){
15 direction = direction || 'ASC';
16 var dir = direction == 'ASC' ? 1 : -1;
17 var st = this.fields.get(f).sortType;
18 //關(guān)鍵地方,重寫排序排序規(guī)則
19 var fn = function(r1, r2){
20 if(!r1.get('isValidateTest')||!r2.get('isValidateTest')){
21 //無效數(shù)據(jù)永遠(yuǎn)在下面
22 return !r1.get('isValidateTest') ? dir : -dir;
23 }else{
24 var v1 = st(r1.data[f]), v2 = st(r2.data[f]);
25 return v1 > v2 ? 1 : (v1 < v2 ? -1 : 0);
26 }
27 };
28 this.data.sort(direction, fn);
29 if(this.snapshot && this.snapshot != this.data){
30 this.snapshot.sort(direction, fn);
31 }
32 }
33 });
http://atian25.javaeye.com/blog/417361
1.表頭提示
在2.2里面是設(shè)置ColumnModel.tooltip
,3.0則是Column.
tooltip
如下:
1 var grid = new Ext.grid.GridPanel({
2 columns:[
3 {header:'名稱',dataIndex:'name',tooltip:'對象名稱'},
4 {header:'開始時間 - 結(jié)束時間 <br/>成功/失敗/成功率', dataIndex:'sucRate',tooltip:'成功/失敗/成功率'}
5 ]
6 });
2.單元格提示
1)使用Ext.QuickTips
在開始的時候就執(zhí)行Ext.QuickTips.init();
然后對需要提示的單元格,重寫renderer函數(shù),添加ext:qtitle , ext:qtip這2個屬性即可。
這個在官方的FAQ上有詳細(xì)描述: http://extjs.com/learn/Ext_FAQ_Grid#Add_ToolTip_or_Qtip
代碼:
1 //option 1
2 //========
3 renderer = function (data, metadata, record, rowIndex, columnIndex, store) {
4 //build the qtip:
5 var title = 'Details for ' + value + '-' + record.get('month') +
6 '-' + record.get('year');
7 var tip = record.get('sunday_events');
8
9 metadata.attr = 'ext:qtitle="' + title + '"' + ' ext:qtip="' + tip + '"';
10
11 //return the display text:
12 var displayText = '<span style="color: #000;">' + value + '</span><br />' +
13 record.get('sunday_events_short');
14 return displayText;
15 };
16
17 //option 2
18 //========
19 renderer = function (data, metadata, record, rowIndex, columnIndex, store) {
20 var qtip = '>';
21 if(data >= 0){
22 qtip = " qtip='yeah'/>";
23 return '<span style="color:green;"' + qtip + data + '%</span>';
24 }else if(data < 0){
25 qtip = " qtip='woops'/>";
26 return '<span style="color:red;"' + qtip + data + '%</span>';
27 }
28 return data;
29 };
30
31 //option 3
32 //========
33 var qtipTpl = new Ext.XTemplate(
34 '<h3>Phones:</h3>',
35 '<tpl for=".">',
36 '<div><i>{phoneType}:</i> {phoneNumber}</div>',
37 '</tpl>'
38 );
39
40 renderer = function (data, metadata, record, rowIndex, columnIndex, store) {
41
42 // get data
43 var data = record.data;
44
45 // convert phones to array (only once)
46 data.phones = Ext.isArray(data.phones) ?
47 data.phones :
48 this.getPhones(data.phones);
49
50 // create tooltip
51 var qtip = qtipTpl.apply(data.phones);
52
53 metadata.attr = 'ext:qtitle="' + title + '"' + ' ext:qtip="' + tip + '"';
54
55 //return the display text:
56 return data;
57 };
2)使用ToolTip
官方也已經(jīng)給出方法:
http://extjs.com/forum/showthread.php?p=112125#post112125
http://extjs.com/forum/showthread.php?t=55690
以上給出的方法是可以讓一個grid里面的元素共享一個tooltip對象。一般用來做rowtip
不過3.0有更好的方式,如下:
3.行提示 RowTip
ExtJS3.0新增的方法,設(shè)置tooltip的delegate
代碼:
1 var myGrid = new Ext.grid.gridPanel(gridConfig);
2 myGrid.on('render', function(grid) {
3 var store = grid.getStore(); // Capture the Store.
4
5 var view = grid.getView(); // Capture the GridView.
6
7 myGrid.tip = new Ext.ToolTip({
8 target: view.mainBody, // The overall target element.
9
10 delegate: '.x-grid3-row', // Each grid row causes its own seperate show and hide.
11
12 trackMouse: true, // Moving within the row should not hide the tip.
13
14 renderTo: document.body, // Render immediately so that tip.body can be referenced prior to the first show.
15
16 listeners: { // Change content dynamically depending on which element triggered the show.
17
18 beforeshow: function updateTipBody(tip) {
19 var rowIndex = view.findRowIndex(tip.triggerElement);
20 tip.body.dom.innerHTML = "Over Record ID " + store.getAt(rowIndex).id;
21 }
22 }
23 });
24 });
4.其他方法
監(jiān)聽GridView或Store的事件,然后通過rowSelector或getRow方法來遍歷,自己加tooltip... 這個方式請無視吧

試用了幾天的Chrome了,感覺不錯,期待插件接口的開放...
最新的Chrome的下載地址是:
http://build.chromium.org/buildbot/snapshots/chromium-rel-xp/
今天無聊,順便看了下Chrome的文件,路徑在C:\Documents and Settings\你的用戶名\Local Settings\Application Data\Google\Chrome\User Data\Default 下面,有個History文件.
用UE打開后發(fā)現(xiàn)是SQLITE文件,于是用SQLITE打開(下載地址:http://www.sqlite.org/sqlite-3_6_2.zip)
操作方法如下:
1)用sqlite3.exe打開History文件
2)用 .tables 命令可以看到有圖中幾個表,從名字我們可以看出有下載記錄,書簽,訪問記錄等等
3)用 .output starred.txt 把輸出重定向到文件
4)用 .dump starred 把書簽表導(dǎo)出
5)接著去找下starred.txt文件就OK了.
文件大致如下,熟悉sql的可以分析下結(jié)構(gòu)(如type=2是文件夾,type=1/3是默認(rèn)的,type=0是書簽)
可以通過這個辦法對書簽進(jìn)行分組管理等轉(zhuǎn)換
1
BEGIN TRANSACTION;
2
3CREATE TABLE starred (id INTEGER PRIMARY KEY,type INTEGER NOT NULL DEFAULT 0,url_id INTEGER NOT NULL DEFAULT 0,group_id INTEGER NOT NULL DEFAULT 0,title VARCHAR,date_added INTEGER NOT NULL,visual_order INTEGER DEFAULT 0,parent_id INTEGER DEFAULT 0,date_modified INTEGER DEFAULT 0 NOT NULL);
4
5INSERT INTO "starred" VALUES(1,1,0,1,'書簽欄',12864879599272250,0,0,12864903712413875);
6INSERT INTO "starred" VALUES(2,3,0,2,'其他書簽',12864879599273250,0,0,12864901410029375);
7INSERT INTO "starred" VALUES(29,0,3825,0,'Gmail',12864881762934500,1,5,0);
8INSERT INTO "starred" VALUES(30,0,438,0,'Google Reader',12864881840111125,3,5,0);
9INSERT INTO "starred" VALUES(31,0,3833,0,'Google Docs',12864881878751125,2,5,0);
10INSERT INTO "starred" VALUES(32,2,0,5,'Google',12864881893109125,0,1,12864898849435375);
11INSERT INTO "starred" VALUES(35,2,0,7,'Book',12864882141057000,3,1,12864891426123000);
12
13CREATE INDEX starred_index ON starred(id,url_id);
14COMMIT;
導(dǎo)入的方法也差不多,把用.import指令。熟悉sql命令的人都知道怎么弄了,用.help可以看到sqlite支持的命令

ps:囧...該文章用CHROME寫的..發(fā)布按鈕按了無效...復(fù)制到IE7去發(fā)布了..
ps2:最新的
Chromium數(shù)據(jù)存在:Local Settings\Application Data\Chromium\User Data\Default 下,書簽存在Bookmarks文件里面,不再存在History里面.
該文件格式如下:

4 "children": [ {
5 "date_added": "12865419024859500",
