Backbone.js路由器混乱（pushState：true，斜杠结尾）

Question

I am using Backbone's router with pushState:true to handle my site's urls. Examples of URLs include:

• http://domain.com/John
• http://domain.com/John/
• http://domain.com/John/photos
• http://domain.com/John/my-latest-photos-2012

Problem : When the user goes to http://domain.com/John/ , the expected function photos is executed. However when the user goes to http://domain.com/John without the trailing slash, nothing happens; my guess is that the trailing backslash defined in root prevented this.

Router

var AppRouter = Backbone.Router.extend({

    routes: {
        '': 'photos',
        'photos': 'photos'
    },

    viewing_username: $('#viewing_username').val(),  // eg: 'John'

    photos: function() {
        console.log('photos');
    }
});

var app = new AppRouter();
Backbone.history.start({
    pushState: true,
    root: '/' + app.viewing_username + '/'
});

jQuery

$('a[data-toggle="tab"]').on('click', function(e) {
    app.navigate(e.target.getAttribute('href'), true);
});

2nd Attempt

Problem:: This time I removed the trailing backslash in root and http://domain.com/John now triggers the route. The problem this time comes when the user is at http://domain.com/John (which I believe is treated by the browser as a page named John ), so when the link (with attribute data-toggle="tab" ) is clicked, the url is changed to http://domain.com/Johnphotos without the seperating / .

How should I solve this problem?

Answer 1

I think your 2nd attempt should work if you update backbone to the latest version. See this discussion:

The changes above were merged 8 days ago.

Answer 2

While @shioyama's answer is correct, I often bypass this strangeness by using wildcard routes, where possible.

For example:

routes:
  'dashboard(/*subroute)': 'index'

Of course, this is not a possibility for many apps, however, it's saved time for me in the past.
