編輯:關於JavaScript     
復制代碼 代碼如下:
function flashChecker() {
var hasFlash = 0;     //是否安裝了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("您安裝了flash,當前flash版本為: " + fls.v + ".x");
else document.write("您沒有安裝flash");
