javascript表单认证如如何结合NET进行写入数据库？
按钮点击就执行JS 认证，认证不通过就不提交，通过就提交，但是下面的代码写好一JS论证，但是如果结合NET？提交就执行NET写入数据库的操作？或者有其他的方法？

<div class="content">
<div class="cont1" style=" width:500px;margin-top:25px; background:#ffffff; padding:10px 50px">
<table align="center" width="978" style="margin:0px auto">
<form name="theForm" id="demo" action="" method="get" onSubmit="return Validator.Validate(this,3)">
<tr>
<td>姓名：</td><td><input name="Name" dataType="Chinese" msg="只允许中文"></td>

<tr>
<td>地址</td><td><input name="Name" dataType="Chinese" msg="只允许中文"></td>

[解决办法]
form 标签 action 设置一下url路径,一般使用.ashx，提交到后台，后台获取表单信息，再插入数据库。
[解决办法]
用ajax吧，利用js调用服务器执行文件。
$(function(){
$.post('submit.ashx',{'action':'submit',...},function(data){ if(data>0) alert('save successfuly!');});});
这里用的是jquery封装好的方法，如果没接触过可以自己写的ajax方法进行调用。
