使用jQuery可以节省大量空间。你只需要使用:

$('#myElement').trigger("click")

使用jQuery可以节省大量空间。你只需要使用:

$('#myElement').trigger("click")

比如一些简单的东西怎么样:

document.getElementById('elementID').click();

IE也支持。

var elem = document.getElementById('mytest1');

// Simulate clicking on the specified element.
triggerEvent( elem, 'click' );

/**
 * Trigger the specified event on the specified element.
 * @param  {Object} elem  the target element.
 * @param  {String} event the type of the event (e.g. 'click').
 */
function triggerEvent( elem, event ) {
  var clickEvent = new Event( event ); // Create the event.
  elem.dispatchEvent( clickEvent );    // Dispatch the event.
}

上面的答案是最好的!然而，当etype = 'click'时，它并没有为我在Firefox中触发鼠标事件。

所以，我修改了文档。createEvent到'MouseEvents'这就解决了这个问题。额外的代码是为了测试是否有其他代码干扰了事件，如果它被取消了，我会将其记录到控制台。

function eventFire(el, etype){
  if (el.fireEvent) {
    el.fireEvent('on' + etype);
  } else {
    var evObj = document.createEvent('MouseEvents');
    evObj.initEvent(etype, true, false);
    var canceled = !el.dispatchEvent(evObj);
    if (canceled) {
      // A handler called preventDefault.
      console.log("automatic click canceled");
    } else {
      // None of the handlers called preventDefault.
    } 
  }
}

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
