在DOMContentLoaded上的document.readyState？ [英] document.readyState on DOMContentLoaded?

问题描述

在支持事件 DOMContentLoaded 和属性 document.readyState 的浏览器中：

In browsers that support the event DOMContentLoaded and the property document.readyState:

当 DOMContentLoaded 触发时，我可以假设 document.readyState 将永远是完成或interactive / 加载 ？

When DOMContentLoaded fires, can I assume that the value of document.readyState will always be either "complete" or "interactive"/"loaded"?

（或者可能是 document.readyState 有时仍然有值加载？）

(Or could it be that document.readyState sometimes still has the value "loading"?)

在您的答案中，请提供对权威来源的引用。

In your answer please provide a reference to an authoritative source.

您可能会想：为什么不只是听 readystatechange ？这是因为Android 2.3.5标准浏览器是一个目标平台，它没有实现 readystatechange 事件。

You may wonder: Why not just listen to readystatechange? It is because the Android 2.3.5 standard browser is a target platform, and it does not implement the readystatechange event.

推荐答案

readyState 属性的值始终为interactive DOMContentLoaded 已触发。事实证明，MDN 文档声称： / p>

The value of the readyState property is always "interactive" when DOMContentLoaded has fired. This is evidenced by the fact that the MDN documentation claims:

document.onreadystatechange = function () {
  if (document.readyState == "interactive") {
    initApplication();
  }
}

可与 DOMContentLoaded 处理程序。您还可以查看规范这里，其中重申了这一点。

is interchangeable with a DOMContentLoaded handler. You can also have a look at the spec here, which reiterates this.
