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

I have a web service that I believe meets the required criteria for cross-domain JavaScript calls for accessing data from CRM that lives outside of CRM, and I am running into some errors creating the JavaScript AJAX Code to access that web service.

The web service runs at aloyegeneraltest1/ReturnJSON.asmx

and I can cause the results shown in the screen shot below to appear by accessing the web service at aloyegeneraltest1/.../GetPriceJSON

My problem is that I am unable to figure out how to properly write the JavaScript code that will actually get the serialized items shown in the web service above.

When I run the page below, and click the "test" button, I get an error stating 0x800a1391 - JavaScript runtime error: 'GetJSONP' is 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 I remove the JQuery reference entirely, that eliminates the undefined function error above, but doing so causes a new unhandled exception error as shown - 0x800a1391 - JavaScript runtime error: '$' is undefined

The modified code that produces the new error looks like 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 to be having some kind of issue with the $ at the start of the Ajax code.

I am completely new to AJAX and am fairly new to development in general so any help or advice that anyone may be able provide regarding how I might resolve this syntax/structure issue would be greatly appreciated.
