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.
UIEvent.initUIEvent()
method initializes a UI event once it's been created.
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
UIEvent()
. The page on
创建和触发事件
gives more information about the way to use these.
event.initUIEvent(type, canBubble, cancelable, view, detail)
type
DOMString
defining the type of event.
canBubble
布尔
deciding whether the event should bubble up through the event chain or not. Once set, the read-only property
Event.bubbles
will give its value.
cancelable
布尔
defining whether the event can be canceled. Once set, the read-only property
Event.cancelable
will give its value.
view
WindowProxy
与事件关联。
detail
unsigned long
specifying some detail information about the event, depending on the type of event. For mouse events, it indicates how many times the mouse has been clicked on a given screen location.
var e = document.createEvent("UIEvent");
// creates a click event that bubbles, can be cancelled,
// and with its view and detail property initialized to window and 1,
// respectively
e.initUIEvent("click", true, true, window, 1);
