Retrieving JSON information from an external API

Having trouble retrieving data from an API to populate the "output" div. The error message says that $ is undefined. Any ideas on what could be missing?

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<meta name="Content-Script-Type" content="text/javascript">
<meta name="Content-Style-Type" content="text/css">
</head>

<body style="margin: 0px; padding: 0px;">

<div id="fullscreen">
<div id="output">

</div>

</div>

</body>
<script>
$.ajax({
type: 'GET',
url: "https://apiurl.com",
dataType: "json",
crossDomain: true,
success: function( response ) {
        console.log( response ); // server response
        var id = response[0];       
        var vname = response[1];
        $('#output').html("<b>id: </b>"+id+"<b> name: </b>"+vname);
}
});
</script>
</html>

Answer №1

As noted by Sirko in the previous feedback, your attempt to utilize the JQuery JavaScript library is failing due to missing inclusion of the library itself.

To rectify this issue, you have two options: either download JQuery from the official website here and include it using the following code:

<script src="path_to_local_jquery.js"/>

Alternatively, you can opt for external inclusion as outlined in the CDN section of the provided link.

Furthermore, remember that script tags should be placed within either the head or body sections of your HTML document. For ensuring that your custom script runs after the page has loaded completely, consider utilizing JQuery's document ready method.

Answer №2

The symbol $ is not a native part of JavaScript; it is actually a shorthand for the popular third-party library jQuery ($ === jQuery).

In order to utilize jQuery, you must first include it as a dependency in your HTML file by adding a script tag with a src attribute pointing to the URI of the source file. Only then can you begin using its features.

<html>
  <head></head>
  <body>
    ...
    ...
    <script src="//code.jquery.com/jquery-3.1.1.js"></script>
    <script>
       $(function () {
         // Your code here
       });
    </script>
  </body>
</html>

Answer №3

Make sure to include jQuery in your project, either by using a CDN link or by downloading and referencing it locally. Ensure the DOM is fully loaded before making any calls. More information on this can be found here

<script src="local_jquery.js"/>
// OR
<script src="https://code.jquery.com/jquery-3.1.1.js"></script>


$(function() {
  $.ajax({
    type: 'GET',
    url: "https://apiurl.com",
    dataType: "json",
    crossDomain: true,
    success: function( response ) {
        console.log( response ); // server response
        var id = response[0];       
        var vname = response[1];
        $('#output').html("<b>id: </b>"+id+"<b> name: </b>"+vname);
    }
   });
});
