ExtJs2.0学习系列(8)--Ext.FormPanel之第五式(综合篇)
在上篇和前面的介绍中，我们基本上对form表单中常见组件有了简单的认识，今天我们做个综合点的例子，向服务器提交下！
其实这篇文章很简单，没有什么发光点，暂放首页半天,忘各位理解！
先来个简单的例子，以说明formpanel如何把数据传给其他页面。
效果图：
现在我们要实现的效果是：点击确定，把值传到另一页面！，如下：
原页面js代码为：
<!---->
Ext.onReady(
function
(){
Ext.QuickTips.init();
var form = new Ext.FormPanel({
frame: true ,
width: 300 ,
// monitorValid:true,//绑定验证
layout: " form " ,
labelWidth: 70 ,
title: " 添加个人信息 " ,
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: " 用户名 " ,
// id:"UserName",
allowBlank: false ,
blankText: " 不能为空，请正确填写 " ,
name: " UserName " ,
anchor: " 90% "
},{
xtype: " textfield " ,
fieldLabel: " 昵称 " ,
// id:"SmallName",
name: " SmallName " ,
anchor: " 90% "
},{
xtype: " datefield " ,
fieldLabel: " 注册日期 " ,
// id:"RegDate",
name: " RegDate " ,
anchor: " 90% "
}],
});
接受页面GetForm.aspx的cs代码为：
Ext.QuickTips.init();
var form = new Ext.FormPanel({
frame: true ,
width: 300 ,
// monitorValid:true,//绑定验证
layout: " form " ,
labelWidth: 70 ,
title: " 添加个人信息 " ,
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: " 用户名 " ,
// id:"UserName",
allowBlank: false ,
blankText: " 不能为空，请正确填写 " ,
name: " UserName " ,
anchor: " 90% "
},{
xtype: " textfield " ,
fieldLabel: " 昵称 " ,
// id:"SmallName",
name: " SmallName " ,
anchor: " 90% "
},{
xtype: " datefield " ,
fieldLabel: " 注册日期 " ,
// id:"RegDate",
name: " RegDate " ,
anchor: " 90% "
}],
});
<!---->
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);
}
因为很简单，我做个简要说明：
{
string UserName = Request.Form[ " UserName " ];
string SmallName = Request.Form[ " SmallName " ];
string RegDate = Request.Form[ " RegDate " ];
Response.Write(UserName + " <br/> " + SmallName + " <br/> " + RegDate);
}
<!---->

几点说明
1 .首先定义submit参数的执行函数，即：
submit: function (){
this .getEl().dom.action = ' GetForm.aspx ' , // 转向页面地址
this .getEl().dom.method = ' POST ' , // 方式
this .getEl().dom.submit(); // 提交！
},
2 .为按钮添加触发相应的提交（取消）事件（这样就不是默认的ajax提交）：
buttons:[{text: " 确定 " ,handler:login,formBind: true },{text: " 取消 " ,handler:reset}]
});
function login(){
form.form.submit(); // 提交
}
function reset(){
form.form.reset(); // 取消
}
3 .如果你想绑定验证，在form表单添加参数monitorValid: true ,然后在按钮配置参数中添加formBind： true ，如
buttons:[{text: " 确定 " ,handler:login,formBind: true },{text: " 取消 " ,handler:reset}]
则只有所有的填写字段都满足条件时， " 确定 " 方可提交！如下图，

好了，一个简单的formpanel的提交的原理弄清楚啦！
有关form提交数据的方法有多种，大家可以参考http://www.17ext.com/showtopic-55.aspx（三种ext提交数据的方式），
以后有机会我们再讨论！
下面我们来做个复杂点（只是样子）的form，示例一下（还是上面的原理）！
效果图：
不过在传过来的页面要记得ValidateRequest="false"，安全编码我就暂且不讨论了！
