i think you have to be a little bit more specific, with exactly what it is that you're looking for, before we can help you. maybe an example?

I'm not allowed to touch the cgi script which generates the page to begin with. so I need a javascript function that will look for the string "you are right" and replace it with an image <img src="right.gif"/>

perhaps using an array since their will be several questions on the page...

I hope that makes sense.

eww. that could be tricky. if the phrase you're looking for isn't stand alone, and inside of some sort of object with an id, like a DIV or SPAN, you're out of luck, with javascript. if it's inside of a DIV, though, i think i can help.

I'd try:

document.body.innerHTML = document.body.innerHTML.replace(RegExp('you are right','gi'), '<img src="right.gif"/>');

your solution is not cross browser - but thank you. I thinked I found the solution:

function replace_image(key) {
if(key == 'you are right'){
document.write('<img src="yes.gif" alt="<-- you are right!" \/>');
}else{
document.write('<img src="no.gif" alt="<-- you are wrong!" \/>');
}
}

</script>
</head>

<body>
<script language="JavaScript">
replace_image('%answer%')
</script>
</body>

It works in IE4+/NS6+.

Anyway, is %answer% some ASP variable or something? Otherwise what you just posted won't do anything in a purely client-side setting.

BTW, next time you have ASP support - let us know. ;)
Much better solutions are possible...
