Uncaught Error: History.js Adapter has already been loaded...

[mandrasch]

Hey Devs!

Very nice plugin/library! Is there a way to get rid of the "Uncaught Error: History.js Adapter has already been loaded... ". I tried with try/catch, but that doesn't work.

I'm using http://labjs.com/ and unfortunately I can't control/check right now if a script was loaded before, so double loading can happen and then historyjs breaks the application with this uncaught error.

Thanks in advance,
Matthias

well you can do this

// Check Existence
if ( typeof History.Adapter !== 'undefined' ) {
    //throw new Error('History.js Adapter has already been loaded...');
        return;
}

Still doesn't work in master, makes Router.js unuseable.

Unfortunately you're not able to catch this error since it's being thrown within the anonymous function that it's defined within.

Here's a workaround - simply unload History.js prior to loading it to ensure that it is able to setup. This has some side effects if you're planning on storing History between page reloads.

<script type="text/javascript">
    delete History
</script>

<script src="http://www.yourwebsite.com/history.js/scripts/bundled/html4+html5/jquery.history.js"></script>

Wonder why there is yet no fix by the dev(s). Why not simply substituting the anon function by ref to a regular function? It's that easy!

I'm gonna go with jclays proposed unload workaround, but it feels a bit stupid to unload everything when it obviously is a bug that should be fixed in this package instead. It is a 4 years old bug now? :-O
