現在我們要實現的效果是:點擊確定,把值傳到另一頁面!,如下:
原頁面js代碼爲:
Ext.onReady(function(){
Ext.QuickTips.init();
var form=new Ext.FormPanel({
frame:true,
width:300,
//monitorValid:true,//綁定驗證
layout:"form",
labelWidth:70,
title:"添加個人信息",
labelAlign:"left",
renderTo:Ext.getBody(),
submit: function(){
this.getEl().dom.action =
'GetForm.aspx',
this.getEl().dom.method='POST',
this.getEl().dom.submit();
},
items:[{
xtype:"textfield",
fieldLabel:"用戶名",
//id:"UserName",
allowBlank:false,
blankText:"不能爲空,請正確填寫",
name:"UserName",
anchor:"90%"
},{
xtype:"textfield",
fieldLabel:"暱稱",
//id:"SmallName",
name:"SmallName",
anchor:"90%"
},{
xtype:"datefield",
fieldLabel:"註冊日期",
//id:"RegDate",
name:"RegDate",
anchor:"90%"
}],
});
接受頁面GetForm.aspx的cs代碼爲:
protected
void Page_Load(object sender, EventArgs e)
{
string UserName = Request.Form["UserName"];
string SmallName = Request.Form["SmallName"];
string RegDate = Request.Form["RegDate"];
Response.Write(UserName +
"<br/>"
+ SmallName +
"<br/>"
+ RegDate);
}
因爲很簡單,我做個簡要說明: //幾點說明
1.首先定義submit參數的執行函數,即:
submit: function(){
this.getEl().dom.action =
'GetForm.aspx',//轉向頁面地址
this.getEl().dom.method='POST',//方式
this.getEl().dom.submit();//提交!
},
2.爲按鈕添加觸發相應的提交(取消)事件(這樣就不是默認的ajax提交):
buttons:[{text:"確定",handler:login,formBind:true},{text:"取消",handler:reset}]
});
function login(){
form.form.submit();//提交
}
function reset(){
form.form.reset();//取消
}
3.如果你想綁定驗證,在form表單添加參數monitorValid:true,然後在按鈕配置參數中添加formBind:true,如
buttons:[{text:"確定",handler:login,formBind:true},{text:"取消",handler:reset}]
則只有所有的填寫字段都滿足條件時,"確定"方可提交!如下圖,
好了,一個簡單的formpanel的提交的原理弄清楚啦!
有關form提交數據的方法有多種,大家可以參考http://www.17ext.com/showtopic-55.aspx(三種ext提交數據的方式),
以後有機會我們再討論!
下面我們來做個複雜點(只是樣子)的form,示例一下(還是上面的原理)!
效果圖:
傳到GetForm.aspx頁面後顯示:
不過在傳過來的頁面要記得ValidateRequest="false",安全編碼我就暫且不討論了!
js代碼:

Ext.QuickTips.init();
