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：
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：

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:[{
               xtype:"panel",
               layout:"column",
               fieldLabel:"用户名",
               isFormField:true,
               items:[{
                         columnWidth:.5,
                         xtype:"textfield",
                         allowBlank:false,
                         blankText:"不能为空，请填写",
                         name:"UserName",
                         anchor:"90%"
               },{
                         columnWidth:.20,
                         layout:"form",
                         labelWidth:40,
                         labelAlign:"right",
                         items:[{
                                   xtype:"radio",
                                   fieldLabel:"性别",
                                   boxLabel:"男",
                                   name:"Sex",
                                   checked:true,
                                   inputValue:"man",//这里如果用value，值是on，所以用inputValue（出现这种情况的是radio,checkbox）
                                   anchor:"95%"
                         }]
               },{
                         columnWidth:.30,
                         layout:"form",
                         labelWidth:1,//让标签宽度为很小的值（奇怪的是为0时反而不行）
                         items:[{
                                   xtype:"radio",
                                   boxLabel:"女",
                                   labelSeparator:"",//去除分隔符“：”
                                   name:"Sex",
                                   inputValue:"woman",
                                   anchor:"95%"
                         }]
               }]
     },{//上面是第一行
               xtype:"panel",
               layout:"column",
               fieldLabel:"出生日期",
               isFormField:true,
               items:[{
                         columnWidth:.5,
                         xtype:"datefield",
                         name:"BirthDate",
                         anchor:"90%"
               },{
                         columnWidth:.5,
                         layout:"form",
                         labelWidth:40,//注意，这个参数在这里可以调整简单fieldLabel的布局位置
                         items:[{
                                   xtype:"combo",
                                   name:"Degree",
                                   fieldLabel:"学位",
                                   store:["小学","初中","高中","专科","本科","硕士","博士"],
                                   emptyText:"请选择适合你的学历",
                                   anchor:"90%"
                         }]
               }]
     },{//上面是第二行
               xtype:"panel",
               layout:"column",
               isFormField:true,
               fieldLabel:"使用框架",
               items:[{

               },{
                         columnWidth:.2,
                         layout:"form",
                         labelWidth:1,
                         items:[{
                                   xtype:"checkbox",

                         }]
               },{
                         columnWidth:.6,
                         layout:"form",
                         labelWidth:1,
                         items:[{
                                   xtype:"checkbox",
                                   boxLabel:"Linq",
                                   labelSeparator:"",
                                   name:"Linq",
                                   inputValue:"linq",
                                   anchor:"95%"
                         }]
               }]
              
     },{//上面是第三行
               xtype:"textfield",
               fieldLabel:"Email",
               name:"Email",
               vtype:"email",//email验证,如果想自定义验证的话，请参见前面的文章
               vtypeText:"email格式错误！",
               anchor:"56%"//控制文本框的长度
              
     },{//上面是第四行
               xtype:"textarea",
               fieldLabel:"个性签名",
               name:"OneWord",
               height:50,
               anchor:"95%"
     },{//上面是第五行
               xtype:"htmleditor",
               fieldLabel:"想说的话",
               name:"WantToSay",
               anchor:"95%",
               enableAlignments:false,//去除左右对齐工具栏
               enableLists:false//去除列表工具栏
     }],
      buttons:[{text:"确定",handler:login,formBind:true},{text:"取消",handler:reset}]
  });
  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！
