Google Closure事件委托a'la jQuery live / on [英] Google Closure event delegation a'la jQuery live/on

问题描述

我需要将事件委托给新创建的元素，我需要为其创建事件附加处理程序。类似的东西：onCreate

I need to delegate event to newly created elements, I need to attach handler to their creation event. Something similar to: onCreate

我不想在创建后通过处理将事件绑定到元素：
jQuery：

I do not want to bind the event to the element after the creation by addressing it: jQuery:

$(element).click(function(){});

我喜欢

$.on('document','spawn', '.item', function(e) {
    if (e.target == this.target) {
        alert('element created: '+this);
    }
});

在google闭包中有办法吗？目标是将事件附加到创建，而不是调用函数附加它。

Is there a way to do so in google closure? the goal is to attach the event on creating and not calling function to attach it.

任何人都可以建议？

感谢

推荐答案

在jQuery类似的东西，但方法是不同的。例如：

So we have something similar in jQuery but the method is different. Here is the example:

$(document).on('spawn', '.item', function(e) {
    if (e.target == this.target) {
        alert('element created: '+this);
    }
});

因此， $（document） ，你可以有元素必须呈现的上下文， .on（）中有三个参数：

So, here under $(document), you can have the context where the element has to present and .on() has three params in it:

• 事件名称/类型


• 事件必须绑定的元素
