Convert size in bytes to human readable format (JavaScript)
function formatBytes(bytes,decimals) {
if(bytes == 0) return '0 Bytes';
var k = 1024,
dm = decimals || 2,
sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'],
i = Math.floor(Math.log(bytes) / Math.log(k));
return parseFloat((bytes / Math.pow(k, i)).toFixed(dm)) + ' ' + sizes[i];
}
// Usage:
// formatBytes(bytes,decimals)
formatBytes(1024); // 1 KB
formatBytes('1024'); // 1 KB
formatBytes(1234); // 1.21 KB
formatBytes(1234, 3); // 1.205 KB
