Js gets the description of the page, and js gets the description

This article describes how to obtain the page description by js. Share it with you for your reference. The specific implementation method is as follows:

Var meta = pt.doc ument. getElementsByTagName ('meta'); var comment _desc = ''; for (I in meta) {if (typeof meta [I]. name! = "Undefined" & meta [I]. name. toLowerCase () = "description") {pai_desc = meta [I]. content ;}}

I hope this article will help you design javascript programs.
