JS to determine whether the browser installed Flash plug-in simple method _javascript tips

1. Directly determine whether there is a flash plugin

var Myflash = (function () {
  if (typeof window). ActiveXObject!= "undefined") {return
    new ActiveXObject ("Shockwaveflash.shockwaveflash");
  } else{return
    navigator.plugins[' Shockwave Flash ']
();

Chrome:

Edge browser to cancel the Window.activexobject, using the Navigator.plugins

Use Window.activexobject in other versions of IE, but will complain:

Automation server cannot create object

This problem arises because the script contained in the page does not create the object correctly

Workaround: Install the "MSXML 4.0 Service Pack 2 (Microsoft XML Core Services)" Patch to download (Install File: Msxmlchs.msi) on Microsoft's Web site, and fix the problem after installation.

Note: script debugging errors may also be related to IE security level, you can reduce the security level of IE to solve this problem, may also need to "scrrun.dll" support, the specific way is: Start-> run-> run the following command "regsvr32 scrrun.dll."

2. Get the version number of Flash

<script>
      (function () { 
        var getflashversion = function () { 
        try { 
            if typeof window. ActiveXObject!= ' undefined ') {return
               parseint (new ActiveXObject (' Shockwaveflash.shockwaveflash ')). GetVariable ("$version"). Split ("") [1].split (",") [0], ten); 
             } else{return
              parseint (navigator.plugins["Shockwave Flash"].description.split (") [2],") "
          catch ( e) {return
            0;
          }
        };
        Console.log (Getflashversion ());
      } ();

 </script>
