Ah IE, its been a while since you and I have danced, but alas, I find you stepping on my feet again.
I’ve been doing some work using jQuery .load() to pull in various .asp includes on a web page. Found out today that this doesn’t work at all in IE7 and IE8. This was confirmed by the following article: Switch’s Blog: IE7/IE8 Strikes Again jQuery Append Workaround. Suckage. So much for keeping my content somewhat separated. I’ll be using .append(), .text() and .hide()/.show() to work around this.
ps: It’s worth stating that I probably would have caught this sooner had I not been using IE9 with its Developer Tools. The Developer Tools are great, but I do find that it doesn’t offer a “true” version of IE8 and IE7 that one would find with an actual install of those browsers.
