它跟蹤歷史相匹配的合適的路由,觸發(fā)回調(diào)來(lái)處理事件并啟用在應(yīng)用程序中的路由。
這是可被用于操縱BackboneJS-歷史的唯一方法。它開(kāi)始監(jiān)聽(tīng)路由和管理歷史可標(biāo)記的URL。
Backbone.history.start(options)
<!DOCTYPE html> <head> <title>History Example</title> <script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.2/underscore-min.js" type="text/javascript"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/backbone.js/1.1.2/backbone-min.js" type="text/javascript"></script> </head> <script type="text/javascript"> //'Router' is a name of the router class var Router = Backbone.Router.extend({ //The 'routes' maps URLs with parameters to functions on your router routes: { "myroute" : "myFunc" }, //'The function 'myFunc' defines the links for the route on the browser myFunc: function (myroute) { document.write(myroute); } }); //'router' is an instance of the Router var router = new Router(); //Start listening to the routes and manages the history for bookmarkable URL's Backbone.history.start(); </script> <body> <a href="#route1">Route1 </a> <a href="#route2">Route2 </a> <a href="#route3">Route3 </a> </body> </html>
讓我們進(jìn)行以下步驟來(lái)看看上面的代碼工作:
保存上述代碼到文件start.html
在瀏覽器打開(kāi)這個(gè)HTML文件。
