I get this message "Object [object Object] has no method 'on'

Question

I get this message:

"Object [object Object] has no method 'on' "

to the code:

$(window).on('resize', function () {
    self.setDimensions();
});

what can I do? I already have jQuery 1.9...

@JasonSperske - If he didn't include jQuery then the error would say `$ is not defined`. — Derek 朕會功夫, Apr 18 '13 at 20:00
@Derek朕會功夫 good point, I think all signs point to an outdated jQuery library — Jason Sperske, Apr 18 '13 at 20:02
Or that something is overwriting `$.fn.on`, though not likely. — , Apr 18 '13 at 20:03
@user: Need more info. All you've done is shown use that you're trying to use the `.on` method, and it doesn't work. Clearly the cause is elsewhere. — , Apr 18 '13 at 20:05

Make sure you use at least jQuery version 1.7

Prior to 1.7, you can replace .on() with .bind() (if you're not using event delegation).

The best would probably be for you to upgrade to the lastest jQuery version - 1.9 ATM.

If you have included the latest version of jQuery, and it still says there is no on, then that means some other library is overwriting $. To solve this issue, try this:

$.noConflict();
jQuery(document).ready(function($) {
    // Use $ here
    var self = mysterious();
    $(window).on("resize", function(){
        self.setDimensions();
    })
});
