DOM - Ready event (Readiness|readyState)

1 - About

A page in a ready state, all images are not finished downloading, including banner ads.

3 - State

The readyNess can be read in the readyState property of the document



The document.readyState property returns:

  • loading while the Document is loading, (ie if the document is associated with an HTML parser, an XML parser, or an XSLT processor)
  • interactive once it is finished parsing but still loading sub-resources,
  • and complete once it has loaded.

The readystatechange event fires on the Document object when this value changes.
