$(window).height() and $(window).width() returning 0 in IE9

[law@…]

From jquery version 1.8.0 and above $(window).height() and $(window).width() returns 0 in IE9. It works in Firefox however.

Please see these examples: ​https://www.defgo.net/demo/201301/1.7.0jquery.min.html (works correctly)

​https://www.defgo.net/demo/201301/1.7.2jquery.min.html (works correctly)

You're in quirks mode. jQuery doesn't support quirks mode. Never has supported quirks mode. The jQuery Migrate plugin would tell you you're in quirks mode, you could use that.

You are right about me being in quirks mode. (it works if I change it to e.g. IE9 Standards).

But you did previously (in 1.7.2 and earlier) support quirks mode (or at least the $(window).height() and $(window).width() worked correctly in quircks mode under those versions).

There is a big difference between supporting something and it happening to work.
