一、创建jvalidate.js工具类：
$.extend($.fn.validatebox.defaults.rules, {
equals: {
validator: function(value,param){
return value == $(param[0]).val();
},
message: '密码不一致！'
}
});二、在页面引入：
<script language="javascript" src="${pageContext.request.contextPath}/script/jquery-1.9.1.js" charset="utf-8"></script>
<script language="javascript" src="${pageContext.request.contextPath}/script/easyUI/jquery.easyui.min.js" charset="utf-8"></script>
<script language="javascript" src="${pageContext.request.contextPath}/script/easyUI/locale/easyui-lang-zh_CN.js" charset="utf-8"></script>
<script language="javascript" src="${pageContext.request.contextPath}/script/jvalidate.js" charset="utf-8"></script>
<link rel="stylesheet" href="${pageContext.request.contextPath}/script/easyUI/themes/default/easyui.css">
<link rel="stylesheet" href="${pageContext.request.contextPath}/script/easyUI/themes/icon.css">三、表单代码：
<div id="easyui_regDialog" class="easyui-dialog" data-options="title:'注册', modal:true,
closable:true,
closed:true,
buttons:[{
text:'注册',
handler:function(){
$('#easyui_regForm').submit();
}
},{
text:'取消',
handler:function(){alert('注册')}
}]" >
<form id="easyui_regForm" method="post">
<table>
<tr>
<td>登陆名称：</td>
<td><input type="text" name="loginName" class="easyui-validatebox" data-options="required:true,missingMessage:'用户名称不能为空'"/></td>
</tr>
<tr>
<td>登陆密码：</td>
<td><input id="reg_pwd" type="password" name="password" class="easyui-validatebox" data-options="required:true,missingMessage:'用户密码不能为空'"/></td>
</tr>
<tr>
<td>确定密码：</td>
<td><input type="password" name="repassword" class="easyui-validatebox" data-options="required:true,missingMessage:'确认密码不能为空',validType:'equals[\'#reg_pwd\']'" /></td>
</tr>
</table>
</form>
</div>
四、脚本代码：
<script type="text/javascript">
$(function(){
$('#easyui_regForm').form({
url:'${pageContext.request.contextPath}/user_login.action',
onSubmit:function(){
},
success:function(data){
alert(data);
}
});
});
</script>
