Error with AJAX in JavaScript for Cross Domain ASMX Web Service JSONP Call -


i have locally running web service believe meets required criteria cross-domain javascript calls accessing external data within dynamics crm, , running errors creating javascript ajax code access external web service.

and can cause results shown in screen shot 1 below appear accessing web service @ http://aloyegeneraltest1/returnjson.asmx/getpricejson

screen shot 1

my problem unable figure out how write javascript code serialized items shown in web service above.

when run page below, , click "test" button, error stating 0x800a1391 - javascript runtime error: 'getjsonp' undefined.

<%@ page language="c#" autoeventwireup="true" codebehind="default.aspx.cs" inherits="clientsidegeneraltest._default" %>  <!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "www.w3.org/.../xhtml1-transitional.dtd">   <html xmlns="http://www.w3.org/1999/xhtml">           <script language="javascript" type="text/javascript" src="scripts/jquery-3.1.1.min.js">  function getjsonp() {   debugger;  $.ajax({     url: "aloyegeneraltest1/.../getpricejson",     type: "post",     contenttype: "application/json; charset=utf-8",     data: '{"name":' + json.stringify(getdata()) + '}'   }).done(function(result) {     alert(result.d);   }).fail(function(result) {     alert(result.d);   });             }  }   </script>  <head runat="server">       <title></title> </head> <body>    <form id="form1" runat="server">  <div>  <input id="button1" type="button"    value="test" onclick="getjsonp()" /><br />   </div>  </form>       &nbsp; </body> </html>

if remove jquery reference entirely, eliminates undefined function error above, doing causes new unhandled exception error shown - 0x800a1391 - javascript runtime error: '$' undefined

the modified code produces new error looks this:

<%@ page language="c#" autoeventwireup="true" codebehind="default.aspx.cs" inherits="clientsidegeneraltest._default" %>  <!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "www.w3.org/.../xhtml1-transitional.dtd">   <html xmlns="http://www.w3.org/1999/xhtml">           <script language="javascript" type="text/javascript">  function getjsonp() {   debugger;  $.ajax({     url: "aloyegeneraltest1/.../getpricejson",     type: "post",     contenttype: "application/json; charset=utf-8",     data: '{"name":' + json.stringify(getdata()) + '}'   }).done(function(result) {     alert(result.d);   }).fail(function(result) {     alert(result.d);   });  }   </script>  <head runat="server">       <title></title> </head> <body>    <form id="form1" runat="server">  <div>  <input id="button1" type="button"    value="test" onclick="getjsonp()" /><br />   </div>  </form>       &nbsp; </body> </html>

it appears having kind of issue $ @ start of ajax code.

i new ajax , new development in general or advise may able provide appreciated.

may these lines of code solve problem

          var jsondata = [your json parameter];              $.ajax({                 async: false,                 type: "post",                 url: [your web service url],                 contenttype: "application/json; charset=utf-8",                                   data: json.stringify({ json: jsondata }),                 datatype: "json",                                 success: onsuccess,                 failure: function(err) {                     alert("error : " + err.d);                 }               });               function onsuccess(data) {                 alert("success:" + data.d);                                    }

you can 1 thing need set access-control-allow-origin & access-control-allow-headers in customeheaders web service web.config file.

 <add name="access-control-allow-origin" value="*" />  <add name="access-control-allow-headers" value="content-type" />

if want allow specific domain , can specific value of domain instead of * value
