Representing Color Using Just An Integer - Javascript

Question

Let' say that I'm using kendo ui color picker widget. The widget expects hexadecimal color values. But the colors are represented by just one integer in the database. So I need a function to convert integer color to hexadecimal color and vice versa.

For example, I have the value -16777216 for a color in db. How can this number represent a color and how can I convert it to hexadecimal format?

How can I do that?

Thanks in advance,

Convert a number to a hexadecimal string with:

var hexString = num.toString(16);

and reverse the process with:

var num = parseInt(hexString, 16);
