Changing button color programmatically

Question

Is there a way to change the color of a button, or at least the color of the button label programmatically? I can change the label itself with

document.getE         


        

Answer 1

Probably best to change the className:

document.getElementById("button").className = 'button_color';

Then you add a buton style to the CSS where you can set the background color and anything else.
