JS小练习代码之二_

JS练习代码

相关的源代码如下:
1.beginFormPanel.js(作用:外层html文件中表单的展现)

<script> 
var beginFormPanel = Ext.extend(Ext.form.FormPanel,{ 
constructor:function() 
{ 
beginFormPanel.superclass.constructor.call 
( 
this, 
{ 
title:"myForm(绝不裸奔)", 
width:418, 
height:180, 
frame:true, 
labelWidth:45, 
style:"margin-left:250px", 
defaultType:"textfield", 
defaults:{anchor:"95%"}, 
items: 
[ 
{ 
fieldLabel:"姓名", 
name:"name" 
}, 
{ 
fieldLabel:"年龄", 
name:"age" 
}, 
{ 
fieldLabel:"性别", 
name:"sex" 
}, 
{ 
fieldLabel:"住址", 
name:"addr" 
} 
], 
buttons: 
[ 
{ 
text:"添加" 
}, 
{ 
text:"修改" 
}, 
{ 
text:"删除" 
} 
], 
renderTo:Ext.getBody() 
} 
) ; 
} 
}) ; 
</script>

2.beginPanel.js(作用:GridPanel与窗口以及窗口中FormPanel的实现)

<script>

//上面不加scope属性则提示this.form为空 
this.form.reset() ; 
this.close() ;

/************************** GridPanel **************************************/ 
var beginMyPanel = Ext.extend(Ext.grid.GridPanel,{

3.静态html页面的表现

<html> 
<head> 
<title></title> 
<link rel="stylesheet" type="text/css" href="../AllRes/resources/css/ext-all.css"/> 
<script type="text/javascript" src="../AllRes/adapter/ext/ext-base.js"></script>

<script type="text/javascript" src="beginPanel.js"></script> 
<script type="text/javascript" src="beginFormPanel.js"></script> 
<script> 
Ext.onReady(function(){ 
Ext.QuickTips.init() ; 
Ext.form.Field.prototype.msgTarget="side" ; 
Ext.apply(Ext.form.VTypes,{ 
"age":function(value) 
{ 
//此处用正则表达式要使 
if(/^\d+$/.test(value)) 
{ 
return true ; 
} 
return false ; 
}, 
"ageText":"请输入正确的年龄!" 
} 
) ; 
/* var newnewMyWindowForm = new myWindowForm() ; 
newMyWindowForm.render(Ext.getBody()) ; 
*/ 
// var newnewMyWindow = new myWindow() ; 
// newMyWindow.show() ; 
var myGridPanel = new beginMyPanel() ; 
var myForm = new beginFormPanel() ; 
//注意下面这句与***** 1 ****** 和 ***** 2 ******的关系 
myGridPanel.on 
( 
"rowselect", 
function(selectedRow) 
{ 
this.getForm().loadRecord(selectedRow) ; 
}, 
myForm 
) ; 
}) ; 
</script> 
</head> 
<body>
