在和前面的介绍中,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:

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:
//
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(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:

传到GetForm.aspx页面后显示:

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!
js代码:
Ext.onReady(
function
(){

  Ext.QuickTips.init();
  
var
 form
=
new
 Ext.FormPanel({

     frame:
true
,
     width:
500
,
     monitorValid:
true
,
//
把有formBind:true的按钮和验证绑定

     layout:
"
form
"
,
     labelWidth:
55
,
     title:
"
添加个人信息
"
,
     labelAlign:
"
right
"
,
     renderTo:Ext.getBody(),
     submit: 
function
(){

                    
this
.getEl().dom.action 
=
 
'
GetForm.aspx
'
,
                    
this
.getEl().dom.method
=
'
POST
'
,
                    
this
.getEl().dom.submit();
              },
     items:[{

function
 login(){

         form.form.submit();
   }
   
function
 reset(){

         form.form.reset();
   }
});

接受cs页面的代码:

protected
 
void
 Page_Load(
object
 sender, EventArgs e)
    {

        
string
 UserName 
=
 Request.Form[
"
UserName
"
];
        
string
 Sex 
=
 Request.Form[
"
Sex
"
];
        
string
 BirthDate 
=
 Request.Form[
"
BirthDate
"
];
        
string
 Degree 
=
 Request.Form[
"
Degree
"
];
        
string
 SpringNet 
=
 Request.Form[
"
SpringNet
"
];
        
string
 NHibernate 
=
 Request.Form[
"
NHibernate
"
];
        
string
 Linq 
=
 Request.Form[
"
Linq
"
];
        
string
 Email
=
Request.Form[
"
Email
"
];
        
string
 OneWord 
=
 Request.Form[
"
OneWord
"
];
        
string
 WantToSay 
=
 Request.Form[
"
WantToSay
"
];

        Response.Write(
"
用户名:
"
 
+
 UserName 
+
 
"
<br/>
"
);
        Response.Write(
"
性别是:
"
 
+
 Sex 
+
 
"
<br/>
"
);
        Response.Write(
"
出生日期:
"
 
+
 BirthDate 
+
 
"
<br/>
"
);
        Response.Write(
"
学位:
"
 
+
 Degree 
+
 
"
<br/>
"
);
        Response.Write(
"
使用框架有:
"
);
        
if
 (SpringNet 
!=
 
null
)
        {

            Response.Write(SpringNet 
+
 
"
,
"
);
        }
        
if
 (NHibernate 
!=
 
null
)
        {

            Response.Write(NHibernate 
+
 
"
,
"
);
        }
        
if
 (Linq 
!=
 
null
)
        {

            Response.Write(Linq 
+
 
"
,
"
);
        }
        Response.Write(
"
<br/>
"
);
        Response.Write(
"
邮件地址:
"
 
+
 Email);
        Response.Write(
"
个性签名:
"
 
+
 OneWord 
+
 
"
<br/>
"
);
        Response.Write(
"
想说的话:
"
 
+
 WantToSay);
    }

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!
谢谢各位朋友的支持!
在下篇中我们接着诉说另外一个组件tabpanel,希望各位支持,拍砖,给我动力!
