弃用
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the 兼容性表格 at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

MouseEvent.initMouseEvent() method initializes the value of a mouse event once it's been created (normally using the Document.createEvent() 方法)。

Events initialized in this way must have been created with the Document.createEvent() method. This method must be called to set the event before it is dispatched, using EventTarget.dispatchEvent() . Once dispatched, it doesn't do anything anymore.

Do not use this method anymore as it is deprecated.

Instead use specific event constructors, like MouseEvent() . The page on 创建和触发事件 gives more information about the way to use these.

句法

event.initMouseEvent(type, canBubble, cancelable, view,
                     detail, screenX, screenY, clientX, clientY,
                     ctrlKey, altKey, shiftKey, metaKey,
                     button, relatedTarget);
					

参数

type

the string to set the event's type to. Possible types for mouse events include: click , mousedown , mouseup , mouseover , mousemove , mouseout .

canBubble

whether or not the event can bubble. Sets the value of Event.bubbles .

cancelable

whether or not the event's default action can be prevented. Sets the value of Event.cancelable .

view

the event's AbstractView. You should pass the window object here. Sets the value of UIEvent.view .

detail

the event's mouse click count. Sets the value of UIEvent.detail .

screenX

the event's screen x coordinate. Sets the value of MouseEvent.screenX .

screenY

the event's screen y coordinate. Sets the value of MouseEvent.screenY .

clientX

the event's client x coordinate. Sets the value of MouseEvent.clientX .

clientY

the event's client y coordinate. Sets the value of MouseEvent.clientY .

ctrlKey

whether or not 控制 key was depressed during the Event. Sets the value of MouseEvent.ctrlKey .

altKey

whether or not alt key was depressed during the Event. Sets the value of MouseEvent.altKey .

shiftKey

whether or not shift key was depressed during the Event. Sets the value of MouseEvent.shiftKey .

metaKey

whether or not meta key was depressed during the Event. Sets the value of MouseEvent.metaKey .

button

the event's mouse button .

relatedTarget

the event's related EventTarget . Only used with some event types (e.g., mouseover and mouseout ). In other cases, pass null .

范例

HTML

<div style="background:red; width:180px; padding:10px;">
  <div id="out"></div>
  <input type="text">
</div>
					

JavaScript

document.body.onclick = function(){
  e = arguments[0];
  var dt = e.target,stag = dt.tagName.toLowerCase();
  document.getElementById("out").innerHTML = stag;
};
var simulateClick = function(){
  var evt = document.createEvent("MouseEvents");
  evt.initMouseEvent("click", true, true, window, 0, 0, 0, 80, 20, false, false, false, false, 0, null);
  document.body.dispatchEvent(evt);
}
simulateClick();

• Event.initEvent() is a simpler method serving a similar purpose. It is also obsolete and shouldn't be used any more.
