How to check if JQuery library is loaded

Written by Ian Carnaghan · 9 sec read >

Use the following code withing your JavaScript tags 

if(jQuery){  
    alert('jQuery loaded');  
}else{
    alert('jQuery not loaded');
}

This method can be used to check if any other JavaScript variable or function exists or is set and thus is not limited to jQuery alone.
