Convert Filesize Bytes to Readable String in Javascript
function readablizeBytes(bytes) {
var s = ['bytes', 'kb', 'MB', 'GB', 'TB', 'PB'];
var e = Math.floor(Math.log(bytes)/Math.log(1024));
return (bytes/Math.pow(1024, Math.floor(e))).toFixed(2)+" "+s[e];
}
var s = ['bytes', 'kb', 'MB', 'GB', 'TB', 'PB'];
var e = Math.floor(Math.log(bytes)/Math.log(1024));
return (bytes/Math.pow(1024, Math.floor(e))).toFixed(2)+" "+s[e];
