Question

I use a function to check if jQuery exist or not in my website! Well, the first lines are :

if (typeof jQuery == 'undefined') {
    // it doesnt exist. I load it
} else {
    console.log($);
    $(document).ready(function() {
        startMyFunction();
    });
};

the problem is that, when I load the page, jQuery is not undefined, so it go directly to the else statment (I see the console.log message).

But, seems that I can’t use it. console.log($) print undefined, and I get $ is not a function when the $(document).ready is called.

How is possible?

If jQuery exists but not $, you have probably loaded jQuery in noconflicts mode.
