I have written a wcf service and Iam calling that from javascript.But I couldnt view any response
My code is ..
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript"                   src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js">

function invokeService() {
$(document).ready(function(){
$.ajax({
type:"GET",
async:false,
url:"http://localhost:8732/IServices/RoleService/json/name/doctor",
contentType:"application/json; charset=utf-8",
dataType:"json",
processData:true,
success:function(result){
AjaxSucceeded(result);
},
eror:AjaxFailed
});
function AjaxSucceeded(result)
{
alert(result);
}
function AjaxFailed(result){
alert(result.status+''+result.statusText);
}
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="button" onclick="javascript:invokeService();" value="Call WCF Service" />
</div>
</form>
</body>

Calling WCF comes later.
First check, this javascript function is getting called or not.
Couple of points:
1. Syntax Fix:
Option 1. $(document).ready(function(){...} should be loaded when the form/body of the page loads. Not at the point when you click on any button. The syntax does not look proper here. Fix this first.
Option 2. Completely remove $(document).ready(function(){ line. This is no longer needed.
Option1 needs slightly more modification than Option2. So better you fix the syntax using Option2.
2. WCF Service/Binding:
To call WCF Service, check the type of the service. It should be AjaxEnabledWCF service. Also check the binding. It should be webHttpBinding.
3. Service Return type:
You are expecting the response as 'json'. Check the service response type. It should be 'JSon'.

you have to write the <system.servicemodel>.. in web.config file.The <script> tag should be in your asp page only.
