今天修BUG的时候，碰到一个需要检测浏览器Adobe Readder插件的问题，废话不多说了，直接上代码：

function Check_AdobeReader() {

var displayString;

var acrobat = new Object();

acrobat.installed = false;

acrobat.version = "0.0";

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

for (x = 0; x < navigator.plugins.length; x++) {

if (navigator.plugins[x].description.indexOf("Adobe Acrobat") != -1) {

acrobat.version = parseFloat(navigator.plugins[x].description.split("Version ")[1]);

if (acrobat.version.toString().length == 1) acrobat.version += ".0";

acrobat.installed = true;

break;

} else if (navigator.plugins[x].description.indexOf("Adobe PDF Plug-In") != -1) {

acrobat.installed = true;

acrobat.version = "8+";

}

} else if (window.ActiveXObject) {

for (x = 2; x < 10; x++) {

try {

oAcro = eval_r("new ActiveXObject('PDF.PdfCtrl." + x + "');");

if (oAcro) {

acrobat.installed = true;

acrobat.version = x + ".0";

}

catch (e) {

}

try {

oAcro4 = new ActiveXObject("PDF.PdfCtrl.1");

if (oAcro4) {

acrobat.installed = true;

acrobat.version = '4.0';

}

catch (e) {

}

try {

oAcro7 = new ActiveXObject('AcroPDF.PDF.1');

if (oAcro7) {

acrobat.installed = true;

acrobat.version = '7.0';

}

catch (e) {

}

return acrobat;

}

当然，以上代码是google出来的，在Chrome , FF , IE10 中均检测成功。
