Show a message if the browser is not internet explorer 9 or greater

Question

I would like to show my users a bar that looks like this, if:

1. Browser is not IE; or
2. Browser is IE but is version 8 or earlier

Answer 1

You could use conditional compiling in conjunction with conditional comments

Here a short overview of how this could work.

1. Always show the bar
2. Set a flag in javascript. IEMinor=false
3. Set the flag to true if IE <= 9, by using a script tag and conditional comments
4. Use conditional compiling to hide the bar if @_jscript_version > 9 (actually not needed) and IEMinor===false

Not Supported

_{I was too lazy to add the script type...}

Here is an example on JSBin which doesn't show the bar in IE 10+ (untested). And shows it in other cases.

Note: I didn't make it look exactly like in the screenshot, you should get that part working

Edit: Using the browsermode of IE to test against IE<10 seems to work
Edit2: Whoops i thought from the picture IE9 is unsupported too, to allow IE9 change lte IE 9 to lt IE 9 and @_jscript_version > 9 to >= 9
