使用带有jquery 3.1.1的stellar.js的未捕获的TypeError

Question

In a single page I'm including only jQuery 3.1.1 and stellar.js for a parallax scrolling effects, but when I try tu use it as $(window).stellar(); I get this error in console:

Uncaught TypeError: f.getClientRects is not a function (jquery-3.1.1.min.js:4)

I tried using the migrate plugin as suggested in many answer, but doesn't solve my problem.

The snippet is just to show you the error.

 $(function(){ $('.main').stellar(); }); 

 <div class="main"> <div class="slide"></div> <div class="slide"></div> <div class="slide"></div> </div> <script src="https://code.jquery.com/jquery-3.1.1.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/stellar.js/0.6.2/jquery.stellar.min.js"></script>

stellar.js is failing because of this piece of code:

$(window).load(function() {
                var oldLeft = self._getScrollLeft(),
                    oldTop = self._getScrollTop();

                self._setScrollLeft(oldLeft + 1);
                self._setScrollTop(oldTop + 1);

                self._setScrollLeft(oldLeft);
                self._setScrollTop(oldTop);
            });

In jquery 3.0 the load event is removed. You can change to on('load', function{});

 $(window).on('load', function() {
                    var oldLeft = self._getScrollLeft(),
                        oldTop = self._getScrollTop();

                    self._setScrollLeft(oldLeft + 1);
                    self._setScrollTop(oldTop + 1);

                    self._setScrollLeft(oldLeft);
                    self._setScrollTop(oldTop);
                });

Here is a "working" fiddle: https://jsfiddle.net/y19x160g/1/ and by working i just say that isn't throwing an error anymore.

PS: I don't know exactly what this library is used for.

In that js fiddle i just copied the not-minified script from current GitHub project: https://github.com/markdalgleish/stellar.js/blob/master/src/jquery.stellar.js and modified the load event.

If you don't wan't to change the code in the actual plugin, you can also just add jQuery migrate to the project, I encountered this same issue with the following setup...

jQuery v3.3.1

Stellar.js v0.6.2

Adding jquery-migrate/3.0.1 to the project fixed the issue.
