  • 0

the following code works perfectly in FireFox 7, but when pulling up the same page in IE 9, the jQuery functions (hide and show) don’t work. However if you open debugger in IE and refresh, everything works fine. It’s like the jQuery code won’t work unless debugger is running and you refresh the page (or start IE with debugger on), which makes it difficult to debug obviously.

all the CSS and scripting are included for this sample. If I need to include any other information please let me know.

    console.log is a problem. Remove it or define it like this in case of absence before calling:

    console = console || {};
console.log = console.log || function(){};
