单线JavaScript检测是否安装了flash

Question

I know there are a bunch of posts asking this question, but all of the answers point to either swfobject or the flash detection kit.

Is there a simple one or two liner in JavaScript just to check if Flash is installed or not? I don't want to have to include a whole js library if there's an simple way to do this.

Answer 1

As a summary of the above comments as requested:

The following SO answer is applicable: How can I detect if Flash is installed and if not, display a hidden div that informs the user?

Especially the comments / discussion of the above question are useful. I only remember that when we have used a Flash check we had combined two checks for some reasons I cannot recall. This was prior the iPad age, nowadays I'd check against the common [x]Pads if these are among the target audience. Maybe you combine the Flash and Browser check, eg once you know the browser is SAFARI/iPad you know it is not supporting Flash.

Try to encapsulate the check so you can change / extend it if required (that was useful for us).

I know you've seen it before; that's because it works.
