Cancel onbeforeunload event handler?

Question

I have an onbeforeunload event handler attached to the page which executes every time the page reloads / gets redirected.

window.onbeforeunload = function()          


        

Answer 1

Not immediately related to this question, but may help someone nevertheless. This is what I use in Angular 1.x and TypeScript:

this.$window.onbeforeunload = () => undefined;
