How to call webservice using javascript

Question

I am using below code to call webservice using javascript:

<head>
    <title>Untitled Page</title>
       <script type="text/javascript" language="JavaScript">
      service = document.getElementById("ViewLink");

     function InitializeService(){
      service.useService('http://myURL/cloudtalk/cloudservice.asmx?wsdl',"CloudService");
     }
     var regtype, regvalue;
     function registerUser(){
      regtype = document.getElementById("Text1").value;
      regvalue =document.getElementById("Text2").value;

      service.CloudService.callService("register", regtype, regvalue);
     }
     function ShowResult(){
    alert(event.result.value);
      }
     </script>
</head>
<body  onload="InitializeService()" id="service" >
<a id="ViewLink"   href="http://"  onclick="registerUser()"  style="behavior:url(webservice.htc);" onresult="onmyresult();"> <font color=maroon>Call</font></a>
  <input id="Text1" type="text" />
        <input id="Text2" type="text" />
        <input id="Button1" type="button" value="Save" onclick="registerUser();" />     
</body>

But i am getting error:"The url is not valid and cannot be loaded"

Does http://myURL/cloudtalk/cloudservice.asmx?wsdl in your browser? — deiga

If the web service URL has a different host (by domain name or port) than the one from which the HTML page is served then your JavaScript is violating the same origin policy and any browser will prevent the web service request from loading.
