You can set a timer and handle timer events to change button color.

Like this:

var iTimerID = null;
var nTAmount = 0;
var oBlinkedElement = null;
var nBlinkTimes = 20; /*How much times field must blink*/

function setFieldBlink( oElement ) {
if (!oElement || !oElement.className)
return;

oBlinkedElement = oElement;
iTimerID = window.setInterval(blinkField, 100);
}

function blinkField()
{
oBlinkedElement.style.backgroundColor = nTAmount % 2 == 0 ? '#eee' :
'#fff';
nTAmount++;

if (nTAmount > nBlinkTimes) {
nTAmount = 0;
window.clearInterval(iTimerID); }
}
