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.
CloseEvent.initCloseEvent()
method initializes the value of a close 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
CloseEvent()
. The page on
创建和触发事件
gives more information about the way to use these.
