Javascript: change based on whether IE7 or not

Question

I would like to change a line of my javascript code based on whether the browser is IE7 or not. Here is the code for any other browser:

function showHint(myId) 
{
    document.getElementById(myId).style.display = "inline-block";
}

For IE7, I want display = "inline".

I've made an attempt at conditional compilation (this showed me how to detect the browser), but it didn't work:

function showHint(myId) 
        {
            document.getElementById(myId).style.display = "inline-block";
            /*@cc_on
                @if(navigator.appVersion.indexOf(“MSIE 7.”)!=-1)
                {
                    document.getElementById(myId).style.display = "inline";
                }
            @*/
        }

Any help is greatly appreciated!

EDIT: I'm not using JQuery.

Answer 1

Set a global determined by the behavior of IE's conditional comment parsing:

<!--[if IE 7]><script> var isIE7 = true; </script><![endif]-->

Answer 2

You need to check navigator.userAgent.

If you use jQuery, you can simply write

if ($.browser.msie && $.browser.version === 7)
