jQuery – test jQuery is running
1. Check for the
jQuery or $ object:- Open your browser’s developer tools (usually by pressing F12 or Ctrl+Shift+I/Cmd+Option+I).
- Navigate to the “Console” tab.
- Type
jQueryand press Enter. - Type
$and press Enter.
If jQuery is loaded, these commands will return the jQuery function or object. If jQuery is not loaded, you will likely receive an “Uncaught ReferenceError: jQuery is not defined” or similar error.
2. Check the jQuery version:
- In the console, type
jQuery.fn.jqueryand press Enter. - Alternatively, type
$.fn.jqueryand press Enter.
This will return the version number of the loaded jQuery library (e.g., “3.6.0”). If jQuery is not loaded, you will encounter an error.
3. Use a conditional check:
- In the console, type
if (typeof jQuery != 'undefined') { console.log("jQuery is loaded!");} else { console.log("jQuery is NOT loaded.");}and press Enter.
This snippet will explicitly tell you whether jQuery is present on the page.
