extjs的css效果及与传统布局结合下的panel的使用及表单提交

一、美化表单：
ExtJS自带的CSS效果可以让表单非常漂亮，在使用前先将ext-all.css文件导入页面，然后加入以下代码

<div class="x-box-ml">
        <div class="x-box-mr">
            <div class="x-box-mc">
                <form id="regform">
                    <fieldset align="middle">
                        <legend><font class="btitle" color="#ff7300"><strong class="style7">帐号信息</strong></font></legend>
                        <table width="100%" align="center">
                            <tr>
                                <td style="text-align: right">
                                     会员Email：
                                </td>
                                <td style="text-align: left" width="300">
                                    <input type="text" id="UserEmail" name="UserEmail" />&nbsp;<span id="msg" style="display: none"></span>
                                </td>
                            </tr>
                            <tr>
                                <td style="text-align: right">
                                     登录密码：
                                </td>
                                <td style="text-align: left">
                                    <input id="UserPwd" name="UserPwd" type="password" />
                                </td>
                            </tr>
                            <tr>
                                <td style="text-align: right">
                                     密码确认：
                                </td>
                                <td style="text-align: left">
                                    <input id="UserPwd1" name="UserPwd1" type="password" />
                                </td>
                            </tr>
                        </table>
                    </fieldset>
                    <div id="regbutton">
                    </div>
                </form>
            </div>
        </div>
    </div>
    <div class="x-box-bl">
        <div class="x-box-br">
            <div class="x-box-bc">
            </div>
        </div>
    </div>

二、绑定及验证表单：
以上只是将表单显示出来了，如需对表单域操作，还需要在JS里写相关的代码进行绑定

var fm2 = new Ext.form.BasicForm('regform');    
                //加入验证框
                 fm2.add(new Ext.form.TextField({
                 allowBlank: false,//不能为空
                 blankText:'EMAIL不能为空，且请确保有效地址！',
                //regex:re,//正则验证
                 invalidText:'EMAIL格式不正确或此EMAIL已被注册！',
                 validator:checkEmail//自定义验证函数
                 }).applyTo(userEmail));  
              
                 fm2.add(new Ext.form.TextField({
                 allowBlank: false,//不能为空
                 blankText:'密码不能为空！'
                 }).applyTo(Ext.get('UserPwd')));
               
                 fm2.add(new Ext.form.TextField({
                 allowBlank: false,//不能为空
                 blankText:'密码不能为空！',
                 invalidText:'2次密码不相同！',
                 validator:vailda//自定义验证函数
                 }).applyTo(Ext.get('UserPwd1')));  
             
               fm2.add(new Ext.form.TextField({
                 allowBlank: false,//不能为空
                 blankText:'会员名称不能为空！'
                 }).applyTo('CustomerName'));

ExtJS能对表单进行非常灵活的验证，上面是将表单的字段绑定起来，同时添加了相应的验证，并且也支持自定义函数验证，以下是对比2个输入框密码是否相同的自定义函数

/**//**
                    * 验证密码是否相同
                   */
                  function vailda()
                  {
                    if(Ext.get('UserPwd').dom.value==Ext.get('UserPwd1').dom.value)
                        return true;
                    else
                        return false;   
                   }
