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!

经过一个简单的传值原理传值后,一个表单就可以把数据存储到数据库中去了!
//注意几点
1.绑定验证的两个参数 monitorValid:true,formBind:true
2.精确布局要注意的参数为和width有关的:width:500,labelWidth:55,columnWidth:.5,anchor:"90%",isFormField:true等
3.radio和checkbox通过inputValue获取值,页面传值
4.多列多组件布局为form和column和form布局组合使用,请参考源码分析!

至此,formpanel的简单使用就告一段落,但是formpanel的应用还远远没有讲到,有机会我们再在高级篇里讨论!
