    Is there a way to cancel the javascript event onbeforeunload, and just have it execute a function and return to the page?

    window.onbeforeunload = function(){
    //execute some logic
    return false;
}

    • 6 Sure. You can write your own web browser that has this feature. – Mike Christensen Commented Sep 23, 2013 at 21:01

    Reset to default 13

    No. You cannot cancel this event. All you can do is have it return a string. That will make the browser ask the user if they want to leave.

    Just imagine if you could block this event! You could make a site that the user could never close! Just imagine all the popups you could make. There's no way browsers are going to allow this.

    No. You can't stop people leaving a page if they want to.

    Yes. You can do this by making it null.

    window.onbeforeunload = null;
