关于javascript:JavaScript事件冒泡和捕获机制

个别的事件处理不须要思考这种状况。然而，这不仅是一个常见面试题，而且有其理论应用场景。

演示筹备

  1. 有父子两个元素

    <div id=”propagate”> <p> 源栈欢迎您 </p> </div>

    为了便于演示，加上一点 CSS 成果：

    <style> #propagate {padding: 30px; border: 1px solid;} #propagate > p {background-color: blue; border: 1px dashed;} </style>

  2. 都注册了事件

    var father = document.getElementById(‘propagate’), child = father.children[0]; father.addEventListener(‘click’, function (event) {console.log(‘event handler on father’); }); child.addEventListener(‘click’, function () {console.log(‘event handler on child’); });

  3. 用户点击在子元素上

@想一想 @：

  1. 这是不是也同时点在了父元素上？
  2. 所以，是不是一次事件就会调用两个 handler？
  3. 那么，先触发的是子元素，还是父元素呢？

演示：略

冒泡和捕捉

浏览器大战_（温习）_的年代，不同的浏览器应用了不同的机制来解决这种场景

  • 冒泡（bubble）：事件从外向外传递，先触发子元素事件，再触发父元素的
  • 捕捉（capture）：事件从外向内传递，先触发父元素事件，再触发子元素的

古代浏览器都按 W3C 规范进行了对立。

当事件行为产生时，有两个“流传”阶段：首先由内向内“捕捉”，而后再从外向外“冒泡”，如下图所示。

addEventListener()管制

那为什么上述演示的后果感觉是只有“冒泡”呢？

因为咱们在绑定事件时（默认）指明了：该事件处理程序只实用 / 响应于冒泡阶段。

addEventListener()还有第三个参数 useCapture，当其为

  • false：事件绑定在冒泡阶段（默认）
  • true：事件绑定在捕捉阶段

演示：

father.addEventListener(‘click’, function (event) {console.log(‘event handler on father’); }, true); child.addEventListener(‘click’, function () {console.log(‘event handler on child’); }, true);

以及：__父 true 子 false，父 false 子 true

了解：上述（由浏览器管制的）①②③④四个阶段始终是存在的，咱们能管制的是：事件处理程序（handler）在哪一个阶段（phase）予以响应。

两个 Target

当初咱们来看一个实在的实用场景：给一个父元素外面的所有子元素绑定 click 事件。

<div id=”propagate”> <p> 源栈欢迎您 </p> <p> 大神小班 </p> <p> 灵便学制 </p> </div>

要求显示_用户所点击 DOM 元素_（如何确定？能不能用 this？）的文本。

实际上，这外面能够应用的有三个对象：

  • event.currentTarget（等同于 this）：JavaScript 代码中绑定事件的 DOM 元素
  • event.target：(用户)点击的 DOM 元素

father.addEventListener(‘click’, function (event) {console.log(‘this === event.target:’ + (this === event.target)); console.log(‘event.target:’ + event.target.innerHTML); // 合乎题意需要 console.log(‘this === event.currentTarget:’ + (this === event.currentTarget)); console.log(‘event.currentTarget:’ + event.currentTarget.innerHTML); });

@试一试 @：当在父子元素上都绑定了事件之后，又各自应用冒泡 / 捕捉，会是一种什么情景？

stopPropagation()

能够设想，事件冒泡 / 捕捉机制极有可能会带来胡乱，所以有时候咱们须要：阻止事件（行为）持续向上传递，这就须要调用：

event.stopPropagation();

留神：propagation 蕴含冒泡和捕捉

演示：采纳冒泡 / 捕捉，在父子元素事件 handler 中增加__stopPropagation()

常见面试题

问 ：stopPropagation() 和 preventDefault()的区别？

  • 分割：都是 event 办法，都能阻止事件产生

  • 区别：

    • preventDefault()阻止的 DOM 元素默认的（不是咱们 JavaScript 开发人员绑定的）事件，如提交按钮的提交，超链接的跳转……
    • stopPropagation()阻止的不是事件自身，是事件的流传，通过阻止事件流传阻止 JavaScript 开发人员的绑定事件
