ExtJS 3.0 在skpet里面的代码提示 (含破解jar)

天猪 — Thu, 13 Aug 2009 13:50:00 GMT

原文地址:http://atian25.javaeye.com/blog/426824

官方的extjs3.0包里面没有提供ext.jsb文件.

于是去官方论坛问了下, 3.0他们提供的是jsb2,基于json的.

现在spket还不支持。

有人重新做了个临时的3.0的jsb文件,如附件。

用法:

1.下载后放到3.0的src目录下 (一定要切记...我就是一时糊涂放错了...在官方那闹了笑话 -.-!!)

2.然后在skpet中如下图设置:

3.设置为默认profile

4.设置完后,关闭所有标签页 ,重启skpet就ok了.

5.提示效果如下图:

关于spket和extjs的ide,请参考:http://www.javaeye.com/topic/161161

09.07.23更新:

skpet出新版本了,支持extjs的jsb2.官方下载:

Spket IDE 1.6.17 released - 22 July 2009

http://spket.com/

09.08.11更新

spket1.6.16的破解包,覆盖即可.

下载地址见http://atian25.javaeye.com/blog/426824文末

09.08.12更新:

ext.jsb2已经包含在官方的压缩包里面了.

或者你可以从我另一篇blog中下载:http://atian25.javaeye.com/admin/blogs/445480

注意:

1.该jsb2文件需要spket1.6.17

2.放置目录为根目录而不是src目录 (跟前面的jsb文件不同)

附件地址见原文地址文末

很实在的一个需求,就是我们只需要extjs的一部分功能,不想把整个类库都包含进来.

所以让我们来定制extjs吧~

1. ExtJS 1.1.1或2.3.0

可以用官方的在线工具来定制: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

现在还没有在线版,可以通过以下方法来自己定制:

1. 下载Ext 3.0.0 SDK. http://extjs.com/products/extjs/download.php?dl=extjs3
2. 下载JSBuilder2. http://extjs.com/products/jsbuilder/ (或者看文末的附件)
3. 下载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解压jar到extjs根目录下,ext.jsb2也放到根目录下

5. 用你的文本编辑器编辑ext.jsb2文件,仅保留你需要的模块

6. jsb2文件中的deployDir: 'ext-3.0.0-build'表示相对输出目录

7. cmd,切换到ext根目录下,执行:

G:\Learning\Web\Javascript\ExtJS\ext-3.0.0> java -jar "JSBuilder2.jar" -p ./ext.jsb2 -d ./

8.等待刷屏完毕后去你在jsb2中指定的目录下找输出吧.

3.试验

一个试验的例子,仅包含Tree组件,如附件

1) resource部分未作过滤

2) 注意依赖关系,如

        name: 'Trees',
        file: 'pkgs/pkg-tree.js',
        isDebug: true,
        pkgs: ['pkgs/cmp-foundation.js']

3)输出的文件树如下:

郁闷...本来都写完的了...结果插入一个表格...JE编辑器就出问题了...内容不见了一半...格式也全乱了...得重来...

翻译的不好,请多见谅。其中有些地方觉得太拗口了,就直接给出原文了,如果你有更好的翻译,请跟帖,谢谢。

Changes, Additions (roughly organized alphabetically)

1.Ext

新增:
- iterate 方法 - 遍历一个数组或对象,对每个元素都执行指定的函数
- isNumber 方法 - 判断传递的参数对象是否是数字
- isString 方法 - 判断传递的参数对象是否是字符串
- isBoolean 方法 - 判断传递的参数对象是否是布尔值
- isDefined 方法 - 判断传递的参数对象是否已经定义

2.Ext.lib.Ajax

变更: 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. 你的按钮现在可以放在任意地方,而不仅限于buttons配置项
- Button现在可以缩放为任意高宽,并且有高级的文字布局。 (Buttons can now scale to any height or width and have advanced text positioning.)
- 新的配置:scale: 'small' , iconAlign : 'left' , arrowAlign : 'right'
变更:
- Button现在是一个有效的BoxComponent,可以被布局管理器管理。 (Button is now a valid BoxComponent and can partake in layout management. )
- Button的实现已经完全重写,所以旧版本时候写的自定义样式/主题需要相应的修改。(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 配置项 - 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 - 检查一个xtype是否已经被注册

8.Ext.Container

新增:
- get()

9.Ext.data.Reader

已过时:
- 推荐使用id, 请用 propertyId 和 idIndex

10.Ext.data.Store

新增:
- store xtypes
- autoDestroy 配置项 - 当store绑定的component被销毁的时候,销毁该Store
- setBaseParam()
变更:
- baseParams可以被load方法传递的同名参数所覆盖。( baseParams may be overwritten by params of same name passed to load() )
已过时:
- 不推荐使用 id ,请用 storeId 代替它
- 不推荐使用 loadexception 事件,请用 exception 事件
- SimpleStore 更名为 ArrayStore

11.Ext.Element

新增:
- mouseenter事件
- mouseleave事件
变更/已过时:
- getAttributeNS() - 已过时,用getAttribute()代替
- autoHeight() - 移除
- alignTo() - 变更参数"position"
- query() - 新增参数"unique"
- focus() - 新增参数"defer"

12.Ext.EventManager

变更:
- within() - can now also check if the passed element is the target or related target

13.Ext.form

新增:
- 当动态添加Container到FormPanel时,Fields会被添加到BasicForm's的集合中。所以BasicForm's setValues 方法现在可以始终对动态添加的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.)
变更:
- Ext.form.Radio/Checkbox - 样式/主题已经被改变,详见http://www.extjs.com/forum/showthread.php?p=312770#post312770.
- Ext.form.TextField - allowBlank的验证行为已经被改变,请参见文档
- Ext.form.FormPanel - buttonAlign does not override the default center for Ext.Panel ('right')

14.Ext.grid.GridPanel

新增:
- columnLines 配置项 (boolean) - adds class ' x-grid-with-col-lines'
- Ext.grid.Column
  - 用来作为columns参数传递给ColumnModel (Instances of this class are used as columns passed to ColumnModel)
  - xtypes可以用来指定一些预先配置好的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 (译注:就是一个用DataView+XTemplate来模拟的Grid,轻量)
- Grid BufferedView Class. Buffered GridView enhances performance by waiting to render rows until they are visible.(译注:对大数据量的Grid有明显的性能提升,实际上就是只渲染用户可见的列,拖动的时候再渲染其他.官方还有其他的一个扩展 Ext.ux.LiveGrid,详见:http://extjs.com/forum/showthread.php?t=17791)

15.Layouts:

新增:
- hbox布局和vbox布局
  - 译注:很有用的两个布局。但区域见不能split,不过官方论坛有扩展。详见官方示例
  - http://extjs.com/deploy/dev/examples/layout-browser/layout-browser.html
  - http://extjs.com/deploy/dev/examples/layout/hbox.html
  - http://extjs.com/deploy/dev/examples/layout/vbox.html
- 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).

16.Ext.Menu

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.(译注:简单的说就是Menu溢出后的滚动效果,默认是开启该效果,可以通过enableScrolling来配置,详见官方示例)
变更/已过时:
- Toolbar and Menu are now proper Containers (formerly extended from BoxComponent). 现在Toolbar和Menu都继承Container
- Breaking change: MenuItem的ids现在已经不是局部变量了,所以你不能在多个menu里面用一个id.建议:用唯一的id或者用itemIds来替代它。(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.(译注:简单的说就是由于menu的继承改变,现在你可以设置Menu为浮动的,或者像平常的组件那样使用它)
- DateItem和ColorItem已经被移出,因为没有必要了,现在你可以把任意组件放入menu的items中
- autoWidth() - 变更为autoSize()

17.Ext.MenuButton - 该类已经被移除,用SplitButton代替它

18.Ext.StatusBar - 该类已经被移出core库,在3.0final版会有个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.(译注:简单的说就是Toolbar溢出后的滚动效果详见官方示例)
变更:
- Toolbar and Menu are now proper Containers (formerly extended from BoxComponent).现在Toolbar和Menu都继承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.(译注:新增的这个属性很有用,就是通过设置的selector对某个元素的子对象设置Tip,在2.0的时候我们经常需要的Gird RowTip,CellTip都可以实现了,不需要实例化很多Tip对象)
- 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.(译注:简单的说就是箭头Tip,详见:http://extjs.com/deploy/dev/examples/simple-widgets/qtips.html)

21.Ext.util.Format

新增/变更:
- 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 类级别的观察/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. 旧的扩展需要相应的进行修改,详见: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.

25.新增:图表Charting (Chart, PieChart, CartesianChart, LineChart, BarChart - numeric, time, category axis) -- (译注:其实就是YUI Chart,可以看:http://developer.yahoo.com/yui/charts/ , 或者可以看下我的blog:ExtJS 3.0 Chart 小用一下 http://atian25.javaeye.com/blog/413947)

26.新增:Ext.FlashComponent (译注:似乎是用了swfobject,管理swf方便多了,不用adobe那又长又臭的代码)

27.新增:Direct (Direct, Ext.data.DirectStore, Ext.data.DirectProxy) - 官方3.0极力推出的东西,详见:http://extjs.com/blog/2009/05/13/introducing-ext-direct/

28.新增:Writer

29.新增:Ext.Spacer - xtype 'spacer' (for empty box component)

30.新增:ButtonGroup (xtype: 'buttongroup') (译注:按钮组,仿office2007风格,详见:http://extjs.com/deploy/dev/examples/button/buttons.html)

31.新增:GroupTabs - (译注:详见http://extjs.com/deploy/dev/examples/grouptabs/grouptabs.html)

32.增强:Debug Console (译注:还是firebug好用,不过它可以看到store等,详见:http://extjs.com/deploy/dev/examples/debug/debug-console.html)

33.新增:Ext.Error

[原创]ExtJS Grid 自定义排序规则

天猪 — Wed, 01 Jul 2009 02:20:00 GMT

有一些需求如:

1.一个文件管理的Grid,要求排序的时候,文件夹永远在顶部

2.一个显示成功率的Grid,要求成功数+失败数=0的数据,不参与排序,永远在底部

ExtJs本身并没有暴露这个接口,所以我们只能自己重写,如下代码:

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   //排序规则
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     //关键地方,重写排序排序规则
19     var fn = function(r1, r2){
20       if(!r1.get('isValidateTest')||!r2.get('isValidateTest')){
21         //无效数据永远在下面
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 });

[原创]ExtJS Grid tooltip的几种实现方式

天猪 — Wed, 01 Jul 2009 02:14:00 GMT

http://atian25.javaeye.com/blog/417361

1.表头提示

在2.2里面是设置ColumnModel.tooltip ,3.0则是Column. tooltip 如下:

1 var grid = new Ext.grid.GridPanel({
2   columns:[
3     {header:'名称',dataIndex:'name',tooltip:'对象名称'},
4     {header:'开始时间 - 结束时间 <br/>成功/失败/成功率', dataIndex:'sucRate',tooltip:'成功/失败/成功率'}
5   ]
6 });

2.单元格提示

1)使用Ext.QuickTips

在开始的时候就执行Ext.QuickTips.init();

然后对需要提示的单元格,重写renderer函数,添加ext:qtitle , ext:qtip这2个属性即可。

这个在官方的FAQ上有详细描述: http://extjs.com/learn/Ext_FAQ_Grid#Add_ToolTip_or_Qtip

代码:

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

官方也已经给出方法:

http://extjs.com/forum/showthread.php?p=112125#post112125

http://extjs.com/forum/showthread.php?t=55690

以上给出的方法是可以让一个grid里面的元素共享一个tooltip对象。一般用来做rowtip

不过3.0有更好的方式,如下:

3.行提示 RowTip

ExtJS3.0新增的方法,设置tooltip的delegate

代码:

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

监听GridView或Store的事件,然后通过rowSelector或getRow方法来遍历,自己加tooltip... 这个方式请无视吧

IE7/FF3可用的获取异常发生所在的行数

天猪 — Fri, 26 Sep 2008 06:26:00 GMT

Error具有下面一些主要属性：

* description: 错误描述 (仅IE可用).
* fileName: 出错的文件名 (仅Mozilla可用).
* lineNumber: 出错的行数 (仅Mozilla可用).
* message: 错误信息 (在IE下同description)
* name: 错误类型.
* number: 错误代码 (仅IE可用).
* stack: 像Java中的Stack Trace一样的错误堆栈信息 (仅Mozilla可用).

在IE里面没有lineNumber. 但可用下面的方法找出:

http://forum.byr.edu.cn/wForum/disparticle.php?boardName=SoftDesign&ID=29948&pos=6&page=1

1 <script type="text/javascript">
2 window.onerror=testError;
3 function testError(){
4  arglen=arguments.length;
5  var errorMsg="参数个数："+arglen+"个";
6  for(var i=0;i<arglen;i++){
7   errorMsg+="\n参数"+(i+1)+"："+arguments[i];
8  }
9  alert(errorMsg);
10  window.onerror=null;
11  return true;
12 }
13
14 function test(){
15 error
16 }
17 test()
18 script>

[原创]导出Google Chrome 书签的办法

天猪 — Mon, 08 Sep 2008 02:36:00 GMT

试用了几天的Chrome了,感觉不错,期待插件接口的开放...
最新的Chrome的下载地址是:http://build.chromium.org/buildbot/snapshots/chromium-rel-xp/

今天无聊,顺便看了下Chrome的文件,路径在C:\Documents and Settings\你的用户名\Local Settings\Application Data\Google\Chrome\User Data\Default 下面,有个History文件.

用UE打开后发现是SQLITE文件,于是用SQLITE打开(下载地址:http://www.sqlite.org/sqlite-3_6_2.zip)
操作方法如下:
1)用sqlite3.exe打开History文件
2)用 .tables 命令可以看到有图中几个表,从名字我们可以看出有下载记录,书签,访问记录等等
3)用 .output starred.txt 把输出重定向到文件
4)用 .dump starred 把书签表导出
5)接着去找下starred.txt文件就OK了.

文件大致如下,熟悉sql的可以分析下结构(如type=2是文件夹,type=1/3是默认的,type=0是书签)
可以通过这个办法对书签进行分组管理等转换

1BEGIN 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,'书签栏',12864879599272250,0,0,12864903712413875);
6INSERT INTO "starred" VALUES(2,3,0,2,'其他书签',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;

导入的方法也差不多,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

示例图:

ps:囧...该文章用CHROME写的..发布按钮按了无效...复制到IE7去发布了..
ps2:最新的Chromium数据存在:Local Settings\Application Data\Chromium\User Data\Default 下,书签存在Bookmarks文件里面,不再存在History里面.
该文件格式如下:

1 {
2    "roots": {
3       "bookmark_bar": {
4          "children": [ {
5             "date_added": "12865419024859500",
6             "name": "Google",
7             "type": "url",
8             "url": "http://www.google.cn/"
9          } ],
10          "date_added": "0",
11          "date_modified": "12865419024859500",
12          "name": "\u4E66\u7B7E\u680F",
13          "type": "folder"
14       },
15       "other": {
16          "children": [  ],
17          "date_added": "0",
18          "date_modified": "0",
19          "name": "\u5176\u4ED6\u4E66\u7B7E",
20          "type": "folder"
21       }
22    },
23    "version": 1
24 }
25
