Question

I am using backbone to build my web app.

Currently I am facing an issue whereby if I am on the home page, I am unable to refresh the same page by just clicking on the ‘home’ button again.

I believe that this is the limitation provided by backbone (does not reload the page if the same URL is called)

Is there any way around this? So that I can trigger a page reload when I click on the home button again i.e. call the same URL again?

Looking at the backbone.js source, it seems as though this is not possible by default, since it only responds to a url change. And since clicking the same link, you would not trigger a change event.

Code in Backbone.History:

$(window).bind('hashchange', this.checkUrl);

You’ll need to handle a non-change yourself. Here’s what I did:

$('.nav-links').click(function(e) {
    var newFragment = Backbone.history.getFragment($(this).attr('href'));
    if (Backbone.history.fragment == newFragment) {
        // need to null out Backbone.history.fragement because 
        // navigate method will ignore when it is the same as newFragment
        Backbone.history.fragment = null;
        Backbone.history.navigate(newFragment, true);
    }
});
