How do I verifying if site has javascript enabled and if user's browser is IE 8

Question

How do I verify if a site has Javascript enabled and if user's browser is IE 8?

Answer 1

Use conditional comments and some javascript code (it will work only if it's enabled, right? :))

<!--[if IE 8]>
<script type="text/javascript"> /*do something in JS - it's enabled!*/ </script>
<[endif]-->

Or you may want to look at conditional compilation in JS

Answer 2

If for whatever reason you need to know that you are dealing with IE8,

you have to watch for the IE9 preview, which smells like IE8, but has some new objects:

<!--[if IE 8]>
<script type="text/javascript">
if(document.addEventListener) alert('IE9');
if(document.documentMode) alert('IE8'+ running as '+document.documentMode);

</script>
<[endif]-->
