[thelist] Access text box sizing question

[Matthew Fischer]

This will give the user an alert if they type a 161st character, then chop it off (if they have javascript enabled, obviously):


<SCRIPT LANGUAGE="JavaScript">
<!--

function tooLong() {

    if (document.myForm.test.value.length > 160) {
    alert('Please limit your input in this field to 160 characters.');
    document.myForm.test.value = document.myForm.test.value.substring(0,160);
    }
    
}

//-->
</SCRIPT>

<form name="myForm">
<textarea name="test" cols="40" rows="4" onKeyUp="tooLong()">
</textarea>
</form>
