Doing a german site, and have a JS alert to say you havn’t completed

  • 0

Doing a german site, and have a JS alert to say you havn’t completed all the required fields.

So want to get the langage of the HTMLpage

Here’s the HTML;

<html xml:lang="de" xmlns="http://www.w3.org/1999/xhtml">
  ...
</html>

This is my JS…. it seems to error and not alert at all with the lang bits…

How do it get the xml:lang attribute?

var lang = document.getElementByTagname("html").attributes.getNamedItem("xml:lang").value;
                alert("You must complete all the required information");
                alert(lang);

    Since you have an xml:lang attribute and not a lang attribute, you aren’t writing HTML Compatible XHTML, therefore:

    var htmls = document.getElementsByTagNameNS('http://www.w3.org/1999/xhtml', 'html');
var html = htmls[0];
var lang = html.getAttributeNS('http://www.w3.org/XML/1998/namespace', 'lang');.

    (OK, this is slightly tongue in cheek. You should probably fix your markup to conform to the compatibility guidelines instead. Then just

    document.getElementsByTagName('html')[0].lang

    )
