jquery - Unable to retrieve JSON data from url in html page using javascript -


i have created sample wcf service retrieving data database , display json data in browser.this task completed successfully.

the json data received url is:

{"shipmentdetails":[{"name":"aaa","number":"123"},{"name":"bbb","number":"321"}]}

after creating above service task view same data in html page when button clicked. using javascript/jquery receiving data url, when clicked button no action performed.

following html javascript:

<html> <head> <title>json</title> <script language="javascript" type="text/javascript" src="http://code.jquery.com /jquery-1.5.min.js"> </script>   <script language="javascript" type="text/javascript" >  $(document).ready(function(){      $("testbutton").click(function() {         $.ajax({            type: "get",            datatype: 'jsonp',            contenttype: "application/jsonp; charset=utf-8",            url: "http://localhost:4148/eis.svc/getshipment/arun/arun",            success: function (data) {                obj = eval('(' + data + ')');                alert(obj);                var innerhtml = "";                document.getelementbyid('test').innerhtml=obj;                       //'test' id of <label1>                document.getelementbyid('testlab').innerhtml=obj.shipmentdetails[0].name;                      //'testlab' id of <label2>                $("#test").html(innerhtml);                alert("json data");                alert(obj.shipmentdetails[0].number);                },                error: function (xmlhttprequest, textstatus, errorthrown) {                  alert("error while retrieval – " + xmlhttprequest.responsetext+":"+textstatus+":"+errorthrown);                  }               });          });       });   </head> <body> <input type="button" id="testbutton" value="get json"/> <label id="test"></label> <label id="testlab"></label> </body> </html>

have url string instead of variable name!

 type: 'get', url: serviceurl /* instead of 'serviceurl'*/,

here complete code

  $('#testbutton').click(function() {           //'testbutton' id of button input type in html     alert("button clicked");         var serviceurl="http://localhost:4148/eis.svc/getshipment/json/data";      $.ajax({          type: 'get',      url: serviceurl,      data:$('#serviceurl').serialize(),      processdata: false,      datatype: 'jsonp',      contenttype: "application/jsonp; charset=utf-8",      //if call succeeds      success:function (data) {          alert(data);      },       //if call fails       error: function (xmlhttprequest, textstatus, errorthrown) {       alert("error while retrieval – " +         xmlhttprequest.responsetext+":"+textstatus+":"+errorthrown);       }       });         return false;      });
