摘要: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

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>
/**************************** FormPanel *****************************************************/
var myWindowForm = Ext.extend(Ext.form.FormPanel,{
constructor:function()
{
myWindowForm.superclass.constructor.call
(
this,
{
labelWidth:45,
defaultType:"textfield",
defaults:{anchor:"93%"},
style:"padding:5px",
baseCls:"x-plain",
items:
[
{
fieldLabel:"姓名",
name:"name",
allowBlank:false,
blankText:"姓名不能够为空!"
},
{
fieldLabel:"年龄",
name:"age",
allowBlank:false,
vtype:"age",
blankText:"年龄不能够为空!"
},
{
fieldLabel:"性别",
name:"sex",
allowBlank:false,
blankText:"性别不能够为空!"
},
{
fieldLabel:"住址",
name:"addr",
allowBlank:false,
blankText:"住址不能够为空!"
}
]
}
) ;
},
getValues:function()
{
if(this.getForm().isValid())
{
return new Ext.data.Record(this.getForm().getValues()) ;
}
else
{
throw error("表单验证没通过哦!") ;
}
},
setValues:function(record)
{
this.getForm().loadRecord(record) ;
},
reset:function()
{
this.getForm().reset() ;
}
}) ;
/******************************** Window ***********************************/
var myWindow = Ext.extend(Ext.Window,{
form:new myWindowForm(),
constructor:function()
{
myWindow.superclass.constructor.call
(
this,
{
title:"myWindow(绝不裸奔)",
width:300,
height:185,
frame:true,
plain:true,
modal:true,
items:this.form,
closable:false,//禁止关闭
collapsible:true,//可折叠
buttons:
[
{
text:"确定",
handler:this.onSubmitClick,
scope:this
},
{
text:"取消",
handler:this.onCancelClick,
scope:this
}
]
}
) ;
this.addEvents("submit") ;
},
close:function()
{
this.hide() ;
},
onSubmitClick:function()
{
/*
try
{
this.fireEvent("submit",this,this.form.getValues()) ;
}
catch (error)
{
Ext.Msg.alert("警告","请将需要填写的信息填写完整!") ;
}
*/
this.fireEvent("submit",this,this.form.getValues()) ;
this.close() ;
},
onCancelClick:function()
{
//上面不加scope属性则提示this.form为空
this.form.reset() ;
this.close() ;
}
}) ;

没有html代码,只有JS代码,小练习内容如下:(从陈治文老师的课程中学到)
<script>
Ext.onReady(function(){
// Ext.Msg.alert("系统提示(thtwinj2ee)","环境配置正确!") ;
var myPosition = Ext.data.Record.create(
[{name:"position"}]
) ;//返回一个function
new Ext.Window({
title:"测试用窗口(绝不裸奔)",
width:550,
height:370,
labelWidth:70,
plain:true ,
layout:"form",
defaults:{anchor:"95%"},
// buttonAlign:"center",
items:
[
{
layout:"column",
baseCls:"x-plain",
style:"padding:8px",
items:
[
{
columnWidth:.5,
layout:"form",
baseCls:"x-plain",
labelWidth:70,
defaults:{width:150},
defaultType:"textfield",
items:
[
{
fieldLabel:"姓名"
},
{
fieldLabel:"年龄",
value:23,
readOnly:true
},
{
xtype:"datefield",
format:"Y-m-d",
value:"1986-11-16",
readOnly:true,
fieldLabel:"出生日期",
listeners:
{
"blur":function(_df)
{
var _age = _df.ownerCt.findByType("textfield")[1] ;
_age.setValue(new Date().getFullYear() - _df.getValue().getFullYear()
