javascript调用wcf服务 [英] javascript call to a wcf service

问题描述

Hii，



我做了一个WCF REST服务，它以JSON格式返回响应，现在我想从javascript调用它。但是当我尝试打电话给我，我看不到任何回复。

要拨打javascript电话，我写了这个：

 <   script     src   =  Scripts / jquery-1.5.2.min.js   类型  =  text / javascript >  
 <   / script  >  
 <   script     language   =  javascript     type   = < span class =code-keyword> text / javascript >  
 function Greeting（）{
 
 $（＃btnWCFREST）。click（function（）{
 $ .ajax（{
 url：http：// localhost：8732 / Services / RoleService / json / Role / provider，
 
类型：GET，
 dataType：json，
 
 contentType：application / json; charset = utf-8，
成功：函数（msg）{
 alert（msg）; 
}，
错误：函数（msg）{
 alert（ 失败）; 
} 
} 
 
）; 
} 
} 
 
 
 <   / script  >  

如何得到回复。我哪里出错？



谢谢..

函数CallService（）{

Hii,

I have made a WCF REST service which returns the response in JSON format and now I want to call it from javascript.But when I try to call it I couldn''t view any response.
To make a javascript call I have written this:

<script src="Scripts/jquery-1.5.2.min.js" type="text/javascript">
   </script>
   <script language="javascript" type="text/javascript">
       function Greeting() {
          
           $("#btnWCFREST").click(function() {
           $.ajax({
           url:"http://localhost:8732/Services/RoleService/json/Role/provider",
          
           type:"GET",
           dataType:"json",
         
            contentType:"application/json; charset=utf-8",
            successs:function(msg){
            alert(msg);
            },
            Error:function(msg){
            alert("Failed");
            }
            }

            );
            }
            }


   </script>

How can I get the response.Where Am I going wrong?

Thanks..
