Value to hexadecimal

I get my value like this

var dataView= new DataView(imgData.array.buffer); var st = dataView.getUint8(1).toString(10);

Which gives me the value 216 decimal. How can I transform varibale st to (hex 0xD8).

When i have to 0xD8 how can I transform it to short and long!

I guess this is the way to go:

var st = "0x" + dataView.getUint8(1).toString(16).toUpperCase();

I think you should use 16 instead of 10 as arguement to toString()

Use a different base in the toString call:

var dataView= new DataView(imgData.array.buffer);
var st = dataView.getUint8(1).toString(16);
