+---
+<p>本文演示了如何创建和分派DOM事件。这些事件通常称为<strong>合成事件</strong>,而不是浏览器本身触发的事件。</p>
+
+<h2 id="创建自定义事件">创建自定义事件</h2>
+
+<p>Events 可以使用 <a href="/zh/docs/Web/API/Event"><code>Event</code></a> 构造函数创建如下:</p>
+
+<pre class="brush: js">var event = new Event('build');
+
+// Listen for the event.
+elem.addEventListener('build', function (e) { ... }, false);
+
+// Dispatch the event.
+elem.dispatchEvent(event);</pre>
+
+<p>上述代码使用了 <a href="https://wiki.developer.mozilla.org/en-US/docs/Web/API/EventTarget/dispatchEvent">EventTarget.dispatchEvent()</a> 方法。</p>
+
+<p><span style="line-height: 1.5;">绝大多数现代浏览器中都会支持这个构造函数(Internet Explorer 例外)。 要了解更为复杂的方法,可参考下面的 </span><a href="#The_old-fashioned_way" style="line-height: 1.5;" title="#过时的方式">过时的方式</a><span style="line-height: 1.5;">  一节。</span></p>
+
+<h3 id="添加自定义数据_–_CustomEvent">添加自定义数据 – CustomEvent()</h3>
+
+<p>要向事件对象添加更多数据,可以使用 <a href="/zh-CN/docs/Web/API/CustomEvent">CustomEvent</a> 接口,detail 属性可用于传递自定义数据。<br>
+ 例如,event 可以创建如下:</p>
+
+<pre class="brush: js">var event = new CustomEvent('build', { 'detail': elem.dataset.time });</pre>
+
+<p><span style="line-height: 1.5;">下面的代码允许你在事件监听器中访问更多的数据:</span></p>
+
+<pre class="brush: js">function eventHandler(e) {
+ log('The time is: ' + e.detail);
+}
+</pre>
+
+<h3 id="过时的方式">过时的方式</h3>
+
+<p>早期的创建事件的方法使用了受Java启发的API。下面展示了一个示例:</p>
+
+<pre class="brush: js">// Create the event.
+var event = document.createEvent('Event');
+
+// Define that the event name is 'build'.
+event.initEvent('build', true, true);
+
+// Listen for the event.
+document.addEventListener('build', function (e) {
+ // e.target matches document from above
+}, false);
+
+// target can be any Element or other EventTarget.
+document.dispatchEvent(event);
+</pre>
+
+<h3 id="事件冒泡">事件冒泡</h3>
+
+<p>通常需要从子元素触发事件,并让祖先捕获它:</p>
+
+<pre class="brush: html">&lt;form&gt;
+ &lt;textarea&gt;&lt;/textarea&gt;
+&lt;/form&gt;</pre>
+
+<pre class="brush: js">const form = document.querySelector('form');
+const textarea = document.querySelector('textarea');
+
+// Create a new event, allow bubbling, and provide any data you want to pass to the "details" property
+const eventAwesome = new CustomEvent('awesome', {
+ bubbles: true,
+ detail: { text: () =&gt; textarea.value }
+});
+
+// The form element listens for the custom "awesome" event and then consoles the output of the passed text() method
+form.addEventListener('awesome', e =&gt; console.log(e.detail.text()));
+
+// As the user types, the textarea inside the form dispatches/triggers the event to fire, and uses itself as the starting point
+textarea.addEventListener('input', e =&gt; e.target.dispatchEvent(eventAwesome));</pre>
+
+<h3 id="动态创建和派发事件">动态创建和派发事件</h3>
+
+<p>元素可以侦听尚未创建的事件:</p>
+
+<pre class="brush: html"><code>&lt;form&gt;
+ &lt;textarea&gt;&lt;/textarea&gt;
+&lt;/form&gt;</code></pre>
+
+<pre class="brush: js">const form = document.querySelector('form');
+const textarea = document.querySelector('textarea');
+
+form.addEventListener('awesome', e =&gt; console.log(e.detail.text()));
+
+textarea.addEventListener('input', function() {
+ // Create and dispatch/trigger an event on the fly
+ // Note: Optionally, we've also leveraged the "function expression" (instead of the "arrow function expression") so "this" will represent the element
+ this.dispatchEvent(new CustomEvent('awesome', { bubbles: true, detail: { text: () =&gt; textarea.value } }))
+});</pre>
+
+
+
+<h2 id="触发内置事件">触发内置事件</h2>
+
+<p>下面的例子演示了一个在复选框上点击(click)的模拟(就是说在程序里生成一个click事件),这个模拟点击使用了DOM方法。<a href="http://developer.mozilla.org/samples/domref/dispatchEvent.html">参见这个动态示例</a></p>
+
+<pre class="brush: js">function simulateClick() {
+ var event = new MouseEvent('click', {
+ 'view': window,
+ 'bubbles': true,
+ 'cancelable': true
+ });
+ var cb = document.getElementById('checkbox');
+ var cancelled = !cb.dispatchEvent(event);
+ if (cancelled) {
+ // A handler called preventDefault.
+ alert("cancelled");
+ } else {
+ // None of the handlers called preventDefault.
+ alert("not cancelled");
+ }
+}
+</pre>
