老实说，这里的答案都不适合我的具体情况。Jquery是出了问题，所以所有这些答案都未经测试。我会说我从上面的@mnishiguchi的回答中建立了这个答案，但这是唯一一件实际上最终有效的事情。

// select the element by finding the id of mytest1
const el = document.querySelector('#mytest1');

// pass the element to the simulateClick function
simulateClick( el );

function simulateClick(element){
    trigger( element, 'mousedown' );
    trigger( element, 'click' );
    trigger( element, 'mouseup' );

    function trigger( elem, event ) {
      elem.dispatchEvent( new MouseEvent( event ) );
    }
}

这没有很好的记录，但我们可以非常简单地触发任何类型的事件。

这个例子将触发50双击按钮:

let theclick = new Event（“dblclick”） for （let i = 0;i < 50;i++）{ action.dispatchEvent（theclick） } <button id=“action” ondblclick=“out.innerHTML+='Wtf '”>TEST</button> <div id=“out”></div>

The Event interface represents an event which takes place in the DOM. An event can be triggered by the user action e.g. clicking the mouse button or tapping keyboard, or generated by APIs to represent the progress of an asynchronous task. It can also be triggered programmatically, such as by calling the HTMLElement.click() method of an element, or by defining the event, then sending it to a specified target using EventTarget.dispatchEvent(). https://developer.mozilla.org/en-US/docs/Web/API/Event

[编辑2022]这个答案真的过时了。现代化。原始答案在底部。

使用元素。dispatchEvent使用新创建的所需类型的Event。

下面是一个使用事件委托的例子。

Fork这个stackblitz项目来玩它。

// Note: {bubbles: true} because of the event delegation ... document.addEventListener(`click`, handle); document.addEventListener(`virtualhover`, handle); // the actual 'trigger' function const trigger = (el, etype, custom) => { const evt = custom ?? new Event( etype, { bubbles: true } ); el.dispatchEvent( evt ); }; // a custom event ;) const vHover = new CustomEvent(`virtualhover`, { bubbles: true, detail: `red` }); setTimeout( _ => trigger( document.querySelector(`#testMe`), `click` ), 1000 ); function handle(evt) { if (evt.target.id === `clickTrigger`) { trigger(document.querySelector(`#testMe`), `click`); } if (evt.type === `virtualhover`) { evt.target.style.color = evt.detail; return setTimeout( _ => evt.target.style.color = ``, 1000 ); } if (evt.target.id === `testMe`) { document.querySelector(`#testMeResult`) .insertAdjacentHTML(`beforeend`, `<p>One of us clicked #testMe. It was <i>${evt.isTrusted ? `<b>you</b>` : `me`}</i>.</p>`); trigger( document.querySelector(`#testMeResult p:last-child`), `virtualhover`, vHover ); } } body { font: 1.2rem/1.5rem verdana, arial; margin: 2rem; } #testMe { cursor: pointer; } p { margin: 0.2rem 0; } <div id="testMe"> Test me can be clicked </div> <p><button id='clickTrigger'>Click #testMe</button></p> <div id="testMeResult"></div>

老答案是:

这是我做的。这很简单，但很有效: 函数eventFire(el, etype){ if (el.fireEvent) { 埃尔。fireEvent('on' + etype); }其他{ var evObj = document.createEvent('Events'); evObj。initEvent(etype, true, false); el.dispatchEvent (evObj); ｝ ｝

document.getElementById("element").click()

只需从DOM中选择元素。该节点具有单击函数，您可以调用该函数。

Or

document.querySelector("#element").click()

对我有效的解决方案.... 点击事件可以在点击按钮或从JavaScript文件中调用。 在这段代码中，要么单击按钮显示警报，要么在某些条件下或无条件地调用它

函数ss () { alert (' dddddddddddddddddddddddd '); ｝ var mybtn = . getelementbyid (btn); mybtn.click (); <！DOCTYPE html > < html > < >头 <标题>页面标题< /名称> < / >头 身体< > <h1>这是一个标题</h1> <p>这是一个段落 <button id="btn" onclick="ss()">点击查看</按钮> . < /身体> < / html >
