Jquery引用和登录事件 代码
[u]复制代码[/u] 代码如下:
<script src="js/jquery-1.4.2.min.js" type="text/javascript"></script> <script type="text/javascript" language="javascript"> $(document).ready(function() {     $('#btnSignin').click     (function()     {       $.ajax       (       {         type: "POST",          contentType: "application/json",         url: serviceURL+"/UserLogin",         data: "{UserLoginID:'"+$('#txtLoginID').val()+"',UserLoginPW:'"+$('#txtLoginPW').val()+"'}",               dataType: 'json',         success: function(result)         {          var user = eval(result.d);           location.href = "Welcome.aspx?userID="+user.UserID         },         error: function(result, status)         {         if(status == 'timeout')         {         alert("The request timed out, please resubmit");         }         else         {         if(result.responseText !="")         {         eval("exception = "+result.responseText);              alert(exception.Message);             }           }         }       }       );     }     );   });     $(document).ready(function() {     $('#btnSignup').click     (function()     {       location.href = "Signup/Signup.aspx";     })      }); </script>
serviceURL类似:var serviceURL = "http://localhost:1742/SoldierServices.asmx"; WebService代码: 代码
[u]复制代码[/u] 代码如下:
/// <summary> /// Summary description for SoldierServices /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ToolboxItem(false)] // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. [System.Web.Script.Services.ScriptService] public class SoldierServices : System.Web.Services.WebService { [WebMethod] public User UserLogin(string UserLoginID, string UserLoginPW) { LoginBusiness lb = new LoginBusiness(); return lb.UserLogin(UserLoginID, UserLoginPW); } [WebMethod] public User GetUserInfo(string UserID) { LoginBusiness lb = new LoginBusiness(); return lb.GetUserInfo(UserID); } }
注意:[System.Web.Script.Services.ScriptService]默认是注释的,要把注释去掉
