backbone.js - 在 Backbone.Router.navigate() 之后运行函数

Question

我想在backbone.navigate 调用之后运行一个函数（以呈现flash 消息）。是否可以？我目前连接到所有事件并检查事件名称是否以“路由：”开头。但这触发得太早了，在我的消息被添加之前......所以我正在考虑在路线完成后运行

# intercept all router navigate and render flash messages if any
renderFlashMessengesOnNavigate = (evt) =>
  if evt.indexOf("route:") is 0 
    console.log "rendering messages after route ..."
    @flashMessenger.render()
window.appRouter.bind "all", renderFlashMessengesOnNavigate
window.authRouter.bind "all", renderFlashMessengesOnNavigate
window.userRouter.bind "all", renderFlashMessengesOnNavigate

Answer 1

试试这个：

var originalNavigate = Backbone.history.navigate;
Backbone.history.navigate = function(fragment, options){
    originalNavigate.apply(this, arguments);

    //your code here
}
