Checking if flash plugin present, failing only in IE (think its basically the javascript engine of IE 9, even when browser&document mode changed with developer tools).

Checking if flash plugin present, failing only in IE (think its basically the javascript engine of IE 9, even when browser&document mode changed with developer tools).

var is_Flash = false;
var is_FlashVersion = 0;

var plugin = (navigator.mimeTypes && 
              navigator.mimeTypes["application/x-shockwave-flash"] &&
              navigator.mimeTypes["application/x-shockwave-flash"].enabledPlugin) ?
              naviga开发者_开发知识库tor.mimeTypes["application/x-shockwave-flash"].enabledPlugin : 0;
if (plugin&&plugin.description) {
    is_Flash = true;
    is_FlashVersion = parseInt(plugin.description.substring(plugin.description.indexOf(".")-1));
}

IE doesnt return the plugin details. Anyone know of a solution?

Can use this to check the object details, IE simply nothing and 0 length on the mimeTypes object.

var obj = navigator.mimeTypes["application/x-shockwave-flash"];
var out = '';
for (var i in obj) {
    out += i + ": " + obj[i] + "\n";
}
alert(out);


Why to reinvent the wheel and have headache: Use this lightweight JS library.

You can detect flash or flash versions easily,without any cross browser issues,


You need to look at ActiveXObjects in ie.

I wrote this little function a while back, maybe you can get some inspiration from it, i have not tested it in ie9 however.-

function hasFlashVersionOrBetter(major, minor) {
    minor = minor || 0;
    var v;
    if (navigator.plugins && navigator.plugins.length > 0) {
        var type = 'application/x-shockwave-flash';
        var mimeTypes = navigator.mimeTypes;
        if (mimeTypes && mimeTypes[type] && mimeTypes[type].enabledPlugin && mimeTypes[type].enabledPlugin.description) {
            v = mimeTypes[type].enabledPlugin.description.replace(/^.*?([0-9]+)\.([0-9])+.*$/, '$1,$2').split(',');
        }
    }
    else {
        var flashObj = null;
        try { flashObj = new ActiveXObject('ShockwaveFlash.ShockwaveFlash'); } catch (ex) { return false; }
        if (flashObj != null) {
            var fV;
            try { fV = flashObj.GetVariable("$version"); } catch (err) { return false; }
            v = fV.replace(/^.*?([0-9]+,[0-9]+).*$/, '$1').split(',');
        }
    }
    if (v) {
        var majorVersion = parseInt(v[0], 10);
        return major > majorVersion || major == majorVersion && minor >= parseInt(v[1], 10);
    }
    return false;
}


        if (navigator.plugins && navigator.plugins.length > 0) {
            var type = 'application/x-shockwave-flash';
            var mimeTypes = navigator.mimeTypes;
            if (mimeTypes && mimeTypes[type] && mimeTypes[type].enabledPlugin && mimeTypes[type].enabledPlugin.description) {
                //Flash Object found.
            }
        }

The above code is working in all the browsers.


Thanks guys for the response but my co-developer found a nice piece of code by adobe that works for all browsers.
