ExtJS—window组件Listeners的使用
捕捉window窗口关闭事件时遇到的问题记录。
使用场景：关闭window的时候增加监听事件。
正确的使用方式：
Code1 Ext.onReady(function(){
2 var win;
3 var button = Ext.get('show-btn');
4
5 button.on('click', function(){
6 // create the window on the first click and reuse on subsequent clicks
7 if(!win){
8 win = new Ext.Window({
9 applyTo : 'hello-win',
10 layout : 'fit',
11 width : 500,
12 height : 300,
13 closeAction :'hide',
14 plain : true,
15 listeners : {'hide':{fn: makesure}},
16 modal:true,
17 items : new Ext.TabPanel({
18 applyTo : 'hello-tabs',
19 autoTabs : true,
20 activeTab : 0,
21 deferredRender : false,
22 border : false
23 }),
24
25 buttons: [{
26 text : 'Submit',
27 disabled : true
28 },{
29 text : 'Close',
30 handler : function(){
31 win.hide();
32 }
33 }]
34 });
35 }
36 win.show(button);
37 });
38 function makesure(){
39 alert('close success');
40 }
41
42 });

<h1>Hello World Window</h1>30
<p>This example shows how to create a very simple modal Window with "autoTabs" from existing markup.</p>31
<input type="button" id="show-btn" value="Hello World" /><br /><br />32
<p>Note that the js is not minified so it is readable. See <a href="hello.js">hellos.js</a> for the full source code.</p>33
34
<div id="hello-win" class="x-hidden">35
<div class="x-window-header">Hello Dialog</div>36
<div id="hello-tabs">37
<!-- Auto create tab 1 -->38
<div class="x-tab" title="Hello World 1">39
<p>Hello</p>40
</div>41
<!-- Auto create tab 2 -->42
<div class="x-tab" title="Hello World 2">43
<p> World!</p>44
</div>45
</div>46
</div>47
</body>48
</html>49
注意：关闭窗口使用hide方法。过使用close方法，在第二次通过button创建window的时候会报错。
