警告 : Removed in Firefox 65.

addNextPaintListener() 方法在 HTMLIFrameElement is used to define a handler to listen for the next MozAfterPaint event coming from the browser <iframe> .

This event provides information about what has been repainted. It is mainly used to investigate performance optimization.

注意： The handler will receive the event once and then be thrown away.

句法

instanceOfHTMLIframeElement.addNextPaintListener(listener);
					

返回

Void.

参数

listener

A function handler to listen for a MozAfterPaint 事件。

范例

var browser = document.querySelector('iframe');
function onNextPaint() {
  console.log("Paint has occured");
}
browser.addNextPaintListener(onNextPaint);
					

规范

Not part of any specification.

浏览器兼容性

Supported since Firefox 47, in chrome code only. Removed completely in Firefox 65.

Unlikely ever to be supported in other browsers.
