Evo jedne kratke skriptice koja proverava da li je određeni plugin kao što su recimo Flash ili Java instalirani u browseru. Važi samo za Firefox i ostale "non-IE" browsere. Usput skripta izlistava sve instalirane pluginove u browseru.

Malo sam se poigrao da detekcija plugina radi i u Internet Exploreru i evo konačnog rezultata. Da bi skripta funkcionisala potrebno je da uz nju bude prikačen i fajl BrowserDetect.class.js čisto zarad identifikacije browsera. BrowserDetect klasa nije moje delo već je preuzeta u celosti sa Quirksmode.com (http://www.quirksmode.org/js/detect.html) pošto se radi o veoma kvalitetnoj skripti.

Ovde se konkretno radi o proveri da li je u okviru browsera instaliran Flash. Za Internet Explorer je u okviru promenjljive IEPluginName porebno unesti puno kvalifikovano ime ActiveX komponente kao što je to u slučaju Flasha ShockwaveFlash.ShockwaveFlash.
