[Webdev] textareas (bah)

[Lee Hosty]

just cause im bored ... here goes ... 

var myFixedValue = 25;

function checkLength() {
  if (document.theform.blah.value.length > myFixedValue) {
    document.theform.blah.value =
document.theform.blah.value.substring(0,myFixedValue);
  }
}

<form name="theform">
<textarea name="blah" onChange="oneliner()"></textarea>
</form>

of if youre a fan of oneliners in javascript :P

function oneliner() { document.theform.blah.value =
(document.theform.blah.value.length > myFixedValue) ?
document.theform.blah.value.substring(0,myFixedValue) :
document.theform.blah.value; }

im too lazy so i havent tested ir properly but it works here on  ... i
dunno which browsers support onChange ... onBlur would probably work just
as well ... and if its all broken then im really sorry to have wasted your
time but it should point you in the right direction ...

>Anyone got a nice simple script that does it without any horrible
>downcounting text boxes or anything?
