how to tell version gsap

[jimeast]

If I download gsap and I didn't write down the version/release number  how can I tell what it is?

Hey jimeast 

 

Just open the file and there will be comments at the top with the version and date.

 

Happy tweening.

Of course! Why didn't I think of that.   Thanks!

You didn't think of it because it's Saturday and you should be out having fun instead of working.

And by the way, you can type this into the console to find out on any live page: 

TweenLite.version

I didn't know that. That's quite handy.

 

Several months ago (at Blake's recommendation) I installed Chrysto's GSAP sniffer. That's been a nice little extension too.  For anyone not familiar with it - it's a Chrome extension that lights up green with the GS version number when you're on a site using GSAP.  More often than not when I see something awesome, that little icon is glowing green so GS is being used quite a lot out there.

 

If anyone wants to install the extension, here's the link:

TweenLite is global, so this is the same thing...

window.TweenLite.version

That's all the GSAP sniffer is checking. It appends the following code to the body, which triggers a custom event.

(function () {

    'use strict';
    
    var haveGSAP = false,
        GSAPVersion = null;

    if (typeof window.TweenLite == 'function') {
        haveGSAP = true;
        GSAPVersion = String(window.TweenLite.version);
    }

    var eventDetail = {
        "haveGSAP": haveGSAP,
        "GSAPVersion": GSAPVersion
    };

    var gsapEvent = new CustomEvent('gsapcheck', {
        'detail': eventDetail
    });
    document.dispatchEvent(gsapEvent);

})();

The reason the sniffer doesn't work on CodePen is because it's only checking the window for TweenLite. On CodePen, everything is loaded in an iframe so GSAP wouldn't be on the window. The only exception to this would be opening up a CodePen in debug mode.
