style.height issue...

Hi all, i have the following function...

function ChangeTextboxSize(size) {

var objBox = document.getElementById("txtComment");
var curHeight = objBox.style.height;
alert(curHeight)

}

and it should return a height of 90px; as defined in my css, yet it returns an empty alert box...can someone enlighten me as to why??

Thanks, Justin

Its doing exactly what it should. It would only return a value IF you used style="..." inside of that div. To get the css styles from the stylesheet you need to use the methods found here http://www.javascriptkit.com/dhtmltutors/dhtmlcascade.shtml

awesome, thanks so much for the help!! :thumbsup:
