I have a input box with the attribute
overflow:hidden;
I have also used javascript to stopped text being entered so that it cant overflow however I would like to be able to remove any overflow if the user manages to insert text into an already full textbox.
Is there anyway in javascript to detect when a texbox has hidden overflow? and remove it
Thanks
Are you trying to set the max number of characters that can be entered? If so:
<input type="text" maxlength="50" />
hi,
if you want to activly trim the text in the input box using javascript you can try:
<html>
<head>
<script>
function clip()
{
var maxLen = 3
var box = document.getElementsByName('myInput')[0];
if (box.value.length > maxLen - 1)
{
box.value = box.value.substring(0,maxLen - 1);
}
}
</script>
</head>
<body>
<input name="myInput" onkeypress="clip()" />
</body>
</html>
this code is not pretty but it shows what you can do, every time the text in the text box gets to long the function trims the text(its a little stronger than what you asked but you can tone it down by changing the event to "onblur"). However, what etc suggested should usually work.
