How to Detect Browser Back Button event - Cross Browser

Question

How do you definitively detect whether or not the user has pressed the back button in the browser?

How do you enforce the use of an in-page back button inside a sin

Answer 1

I solved it by keeping track of the original event that triggered the hashchange (be it a swipe, a click or a wheel), so that the event wouldn't be mistaken for a simple landing-on-page, and using an additional flag in each of my event bindings. The browser won't set the flag again to false when hitting the back button:

var evt = null,
canGoBackToThePast = true;

$('#next-slide').on('click touch', function(e) {
    evt = e;
    canGobackToThePast = false;
    // your logic (remember to set the 'canGoBackToThePast' flag back to 'true' at the end of it)
}
