BackboneJS - Router issues - how to get clean URL's

问题

ok I have

{{#each mainmenu}}
<li>
    <a href="#pages/{{this.url}}"><h2>{{this.name}}</h2></a>
</li>
{{/each}}

and in my router

routes: {
    '': 'index',
    'pages/firstpage' : 'firstpage',
    'pages/secondpage' : 'secondpage',
    'pages/thirdpage' : 'thirdpage'
},
initialize: function () {
   Backbone.history.start({pushState: false});
}

and my json file is:

{
    "name":"First page",
    "id":"1",
    "url":"firstpage"
},
{
    "name":"Second page",
    "id":"2",
    "url":"secondpage"
},
{
    "name":"Third page",
    "id":"3",
    "url":"thirdpage"
}

the way it is right now my URL is "#pages/secondpage" - how can i get the URL to display "pages/secondpage" - i tried "pushState:true" which didnt work... then in my mainmenu.js view I added an event:

events: {
     'click a.second': 'secondpage'
},

secondpage: function() {
    var secondpageRouter = new Backbone.Router();
    var route = 'pages/secondpage';
    secondpageRouter.navigate(route, {trigger: true});
  }

but that didnt work either... when I remove the "#pages/" from the anchor above, I almost get the URL I want "pages/secondpage" - but it says "URL could not be found" after clicking the link. So what's going on here???

Please help anyone?

Understand that you need to be able to serve these urls from the server if necessary, read the docs here: http://backbonejs.org/#History

Then you need to do at least three things.

First, after you have defined your routers, call Backbone.history and make sure pushState is true:

Backbone.history.start({ pushState: true })

Second, get rid of all the # in your links, like this:

<a href="pages/{{this.url}}"><h2>{{this.name}}</h2></a>

Third, and this is important, you need to intercept all clicks on local links and prevent their default behavior, which would be to route you to a new page. This is easy with jQuery:

$(document).on("click", "a[href^='/']", function(event){
  event.preventDefault();
  RouterNameGoesHere.navigate($(event.target).attr("href"), {trigger: true});
});

If you aren't using jQuery, listen to link click events in your views deal with the url in your event handlers. I modified your code to add the event argument and event.preventDefault():

events: {
  'click a.second': 'secondpage'
},

secondpage: function(event) {
  event.preventDefault();
  var secondpageRouter = new Backbone.Router();
  var route = 'pages/secondpage';
  secondpageRouter.navigate(route, {trigger: true});
}
