Using the jquery plugin's removeResize function on "$(window)" throws an exception.

[JoolsCaesar]

I have some code that calls
$(container).resize(myFunc);
and then later
$(container).removeResize(myFunc);

Sometimes the container is an element, other times it is the window object. The resize function has check for when this == window and forwards to the default jquery resize handler. There is no such check in the removeResize function so it goes about trying to splice __resizeListeners__ which don't exist and throws an exception.

Uncaught TypeError: Cannot read property 'splice' of undefined

For those reaching this page when upgrading to jQuery 3.2.1, the same exception gets thrown because __resizeListeners__ is not set on the element if you use jQuery's recommended .on('resize' instead of .resize. This plugin creates a wrapper around $.fn.resize, as per @JoolsCaesar's comment
