复制代码 代码如下:

function flashChecker() {

var hasFlash = 0; //是否安装了flash

var flashVersion = 0; //flash版本

if(document.all) {

var swf = new ActiveXObject('ShockwaveFlash.ShockwaveFlash');

if(swf) {

hasFlash = 1;

VSwf = swf.GetVariable("$version");

flashVersion = parseInt(VSwf.split(" ")[1].split(",")[0]);

}

} else {

if(navigator.plugins && navigator.plugins.length > 0) {

var swf = navigator.plugins["Shockwave Flash"];

if(swf) {

hasFlash = 1;

var words = swf.description.split(" ");

for(var i = 0; i < words.length; ++i) {

if(isNaN(parseInt(words[i]))) continue;

flashVersion = parseInt(words[i]);

}

}

}

}

return {

f: hasFlash,

v: flashVersion

};

}

var fls = flashChecker();

var s = "";

if(fls.f) document.write("您安装了flash,当前flash版本为: " + fls.v + ".x");

else document.write("您没有安装flash");
