//between "<head>" and "</head>"
<script type="text/javascript">
<!--
var iCount = 0;
function changeText(objElement) {
    var oTextCount = document.getElementById("txtCount"); //這個是顯示的id
    var oCount = document.getElementById("hdnCount");  //這個最後會丟給hidden的
    iCount = objElement.value.length;
    oTextCount.innerHTML = "" + iCount;
    oCount.value = parseInt(iCount);
}
//-->
</script>


//這個就是文字欄位
<textarea name="txtTest" cols="50" rows="10" id="txtTest" onkeyup="changeText(this);"></textarea>
