取消绑定骨干查看事件 [英] Unbind Backbone View Events

问题描述

我有下降的事件哈希 -

I have the falling events hash -

events:
  'click #someButton : 'someFunction'

要关闭我尝试过的视图

close:
  $("#someButton").unbind("click")

和

   `close:

       $("#someButton").remove()`

但someFunction仍然被触发了不止一次。如何从按钮中取消绑定此事件？

But someFunction is still being fired more than once. How do I unbind this event from the button?

我也尝试过

$(@el).find("#someButton").unbind("click") as well 

推荐答案

Backbone.js视图事件被委派给视图的 el （所以没有事件绑定到你的 #someButton 元素，而当点击事件冒泡到 el 时，它会检查事件是否来自与该选择符匹配的元素），删除您需要将其从 el 中删除​​的事件，例如

Backbone.js view events are delegated to the view's el (so there is no event bound to your #someButton element but rather when a click event bubbles up to the el it checks to see if the event came from an element matching that selector), that being the case to remove the event you need to remove it from the el, for example

  $(this.el).off('click', '#someButton');

如果要删除所有委派的事件，您只需使用视图的 undelegate 方法

If you want to remove all delegated events you can just use the view's undelegate method
