Auto expanding field

[Fermin Da Costa Gomez]

Hi,

Whilst working on a google-like search i decided i wanted 'my old expanding
inputfield' back.
It is pretty insignificant but you hardly ever come across them, despite the
fact that they can be quite usefull imho .. ;-)

Just thought i would drop it on the list. It can probably be improved upon
but it works ..

...
<script type="text/javascript" language="JavaScript">
<!-- //
// Toggle the display of a set of elements between show and hide
function widenField(currentField) {
    if (currentField.value.length >= (currentField.size-1)) {
        currentField.size =
currentField.value.length+1;//currentField.maxLength + 2;
    }
}
//-->
</script>
...
...
        <input t:id="fieldName" t:type="TextField" t:mixins="autocomplete"
t:minChars="1" t:frequency="0.15"  *onKeyPress="widenField(this)*"/>
