Question

I’ve implemented pushState/onPopState in a small web app I’ve created. The app now throws javascript errors in IE because IE doesn’t support these methods. Is there any way I can do a check like

if (method_exists(history.pushState)) { 

    history.pushState(blah, blah, blah);
}

So that IE will ignore this part of the app and not throw an error? Thanks.

Try this:

if (typeof history.pushState != 'undefined') { 
    history.pushState(blah, blah, blah);
}
