调试易

先学学怎么用 jquery 或者 .net 自带的ajax控件吧

<script type="text/javascript">
      $(document).ready(
        function() {
        alert("123");
           $("#Button2").click(
           function (){
            alert("456");
        var code='<%=code%>'; 
             alert(code);
    var  txtemail= $("#txtemail").val();
        var  txtemail=document.getElementById('txtemail').value; 
             alert(txtemail);               $.ajax({
                 type:"POST",
                contentType:"application/json; charset=utf-8",
                 url:"advisory.aspx/Send",
                  data:"{from:'[email protected]',to:"+txtemail+",cc:'{}',body:"+code+",subject:'邮件标题',mailServer:'smtp.qq.com',port:'25',user:'12345678',password:'123456'}",  
                    dataType:'json',
                success:function(data) {
                   if(data==1)
                  {
                      alert("发送成功"); 
                       var email=txtemail.Substring(txtemail.IndexOf('@') + 1);
                    window.location.href="http://mail.{0}"+email; 
                    }
                    
                  },
                  error: function()
                    {
                    alert("发生错误"); 
                   }
                     
               });
            return false;  
           }
            });
        });
</script>   <input id="Button2" type="button" value="验证"   class="btn"/>
我执行到     $("#Button2").click(
           function (){就没法执行了是哪里出错了，链接跳转也不对

  刚刚多了这个  var  txtemail=document.getElementById('txtemail').value;
