hi all, I am trying to add a textbox into a form that utilises the built in "LEN" function that will return a number of characters typed into another textbox.
For instance if adding a signature in a forum application, and it can only have max200 characters, but rather than just setting the maxValue of the textfield, actually have a seperate box, showing a count as i type.

Creat the function:
function ShowCharacters(){
document.FormName.txtDisplayLength.value = document.FormName.txtTypeHere.value.length
}
Then in the page
</head>
<body bgcolor="#FFFFFF" text="#000000">
<form name="FormName" method="post" action="">
<textarea name="txtTypeHere" onKeyUp="ShowCharacters()"></textarea>
<br>
<input type="text" name="txtDisplayLength">
</form>
</body>
</html>
