Recently I had to be able to detect the Adobe Reader Plugin in Javascript. I have included the code I used to flag if the Adobe Reader Plugin is installed, as well as get the version of the current adobe reader plugin. This code will detect:
To call it in javascript:
- Adobe Reader Plugin for Firefox
- Adobe Reader Plugin for IE ( <5 and 5+)
- Adobe Reader Plugin for Chrome and
- WebKit PDF Reader for Safari
- The PDF Reader for Chrome (Chrome's default alternative to the Adobe Reader Plugin)
- Adobe Reader Plugin for most other browsers
To call it in javascript:
var info = getAcrobatInfo(); alert(info.browser+ " " + info.acrobat + " " + info.acrobatVersion);
