Question

I try to enable a brwoserback button for my tabs. But the problem is that in some cases the the hash dissapears.

function showTab1(){
    window.location.hash = 'tab1';
    oldHash = window.location.hash;
    //showTab1
}
function showTab2(){
    window.location.hash = 'tab2';
    oldHash = window.location.hash;
    //showTab2
}
function checkBrowserBackButtonInHome(){

    setInterval(function(){
        if(window.location.hash != oldHash) {
            //Do something
        }
    }, 50);
} 
showTab1();

and than I click on showTab2. And when I click on the browser back button the hash dissapears. index.php instead of index.php#tab1

EDIT:

It seems like this only happens in chrome web browser

Answer 1

try using this instead of the interval:

$(window).bind('hashchange', function() {
  //Do something
});
