javascript - Why is my code fully compatible in Chrome/Safari, somewhat in FireFox, but hardly at all in Internet Explorer 8? -

i wrote jquery code works in chrome/safari, in firefox, , hardly @ in ie8.

why , how can fix it?

here's code in case you're curious see might cause problems in ie or firefox (you can see code in action on @ http://keepskatinbro.com/):

jquery(".wrap").append("<img src='" + base + "/wp-content/themes/shaken-grid/images/ajax-loader.gif' id='ajax-loader' style='position: fixed; margin-left: 50%; left:-154px; top: 30%; display: none;' />", function() {     jquery("#ajax-loader").hide();

also, pasted above code in jslint , got following, i'm not sure results. of results bogus results don't encompass of javascript on page in it's entirety. results:

i understand things wanting me add {} around callback, why want !== instead of != in cases, etc?

i solved 2 of 3 problems:

when animating entire page (like scrolling content), must target both html , body tags so: $('html, body'). had $('body') code didn't work in ie. chrome needs 'body' while ie needs 'html' in total need include both.

also, comments stripped ajax calls flash embed, uses special conditiontionals html comments ie, comes wrong tags ie. why no video played in ie.

the last problem still persists: firefox fails re-organize boxes on site after opening box. knows why!
