Stop ie 9 using compat mode because of js injection

Hi All Hope you can help,

I am manipulating a cms using server side php (phpQuery Library) which is injecting some minimised js into the header of a HTML page.

My problem is that I want to add meta tags to force ie9 to use standards mode. However when I inject the meta tags with php, the javascript injected after is forcing my meta tags downs and setting ie9 into compat mode.

I have have no control of the injection javascript, but can add my own scripts if this would work.

On looking at view source and inspect element when debugging I can see the js loaded on the page is forcing the meta tags down.

Could I use my own js to get them back up? I was under impression that meta tags need to be set before page load ie server.

Solution

To create a webpage that is displayed in standards mode when viewed with Internet Explorer, use the HTML5 document type directive, as shown in the following code example:

<!DOCTYPE html>
<html>
<head>
  <title>Enabling Standards Support</title>
</head>
<body>
  <p>
     Because this webpage uses the HTML5 document 
     type, it is displayed in IE9 Standards mode.
  </p>

</body>

So your JS should only be added after the

<!DOCTYPE html>

is declared.

If your webpage does not include a !DOCTYPE directive or if it specifies a non-standards mode document type, Internet Explorer displays your webpage in IE5 (Quirks) mode. When this happens, Internet Explorer ignores features in your webpage that require standards mode.
