how do i change fore color in a textbox with javascript

Apr 13th, 2006

I tried several things. i get invalid char or no object. can one change fore color or setup a mask. the text box contains numbers and if the number is negitive i need it to show in red, black if not.
var oRed = '#ff0000'
var oBlack = '#000000'
if (parseInt(document.getElementById('nm1TextBox').value) < parseInt(0))
{document.getElementById('nm1TextBox').forecolor = oRed;}
else
{document.getElementById('nm1TextBox').forecolor = oBlack;}
