The example in this article describes the method of using javascript to detect whether the flash plug-in is disabled. Share it with everyone for your reference, the details are as follows:
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="Generator" content="EditPlus®"> <meta name="Author" content=""> <meta name="Keywords" content=""> <meta name="Description" content=""> <title>Document</title> <script> function demo(){ var flag = false; if(window.ActiveXObject){ try{ var swf = new ActiveXObject("ShockwaveFlash.ShockwaveFlash"); if(swf){ flag = true; } }catch(e){ } }else{ try{ var swf = navigator.plugins['Shockwave Flash']; if(swf){ flag = true; } }catch(e){ } } if(flag){ console.log("running ok"); }else{ console.log("running error"); } } </script> </head> <body> <button onclick="demo();">click</button> </body> </html>
I hope this article will be helpful to everyone in JavaScript programming.
