How Do I Detect the Adobe Acrobat Version Installed in Firefox via JavaScript

问题

I know this can be done in IE by creating an ActiveX object, but how do I do it in FF. The navigator.plugins['Adobe Acrobat'] object lets me know if it's installed or not, but it doesn't contain the version number. Any ideas?

回答1:

navigator.plugins[n].name where n is the index of the Acrobat plugin is supposed have the version number in it. Unfortunately, starting with Adobe Reader 8, they changed the name to "Adobe PDF Plug-In for Firefox and Netscape", with no version information. So, if this is the name you've detected at least Reader 8, but can't tell versions 8 from 9.

Also, make sure you take into account that Macs don't need Acrobat Reader to render PDF files. (I booted my Windows partition just to test this.)

It should be possible to do this like swfobject detects flash version:

回答4:

var p = document.getElementById('Pdf1');
//p.GetVersions()
if(p.GetVersions().indexOf("7.0") != -1)
    alert("Acrobat 7 Found")

This script detects the reader in all browsers - even detects Chrome's PDF Reader...

var browser_info = {
    name: null,
    acrobat : null,
    acrobat_ver : null
  };


if(navigator.plugins != null)
  {      
   var acrobat = navigator.plugins['Adobe Acrobat'];
   if(acrobat == null)
   {           
    browser_info.acrobat = null;
    return browser_info;
   }
   browser_info.acrobat = "installed";
   browser_info.acrobat_ver = parseInt(acrobat.version[0]);                   
  }


where navigator is the property of Window
