I need to use this js script several times, in several form fields. It is working wonderfully for one field but I don't know how to duplicate this script to use in other fields at the same time. Every checkbox choice loads pre-defined values for RegEx completion. So, all the code below belongs to one form field.
<head>
<!-- CHECKBOXSES REGEX 1 -->
<script type="text/javascript">
function getVal(bu){
var el=document.getElementById('col12_filter_prospective');
var i=0, c;while(c=document.getElementById('chk'+(i++)))
{el.value=(bu.checked)? bu.value : null;c!=bu? c.checked =false : null;
}
}
</script>
</head>
<body>
<input type="checkbox" name="chk" value="[^***]" id="chk0" onclick="getVal(this)" title="[^***] Replace (***) with the word to excluded from search.">
<input type="checkbox" name="chk" value="/whatever[^s]*./" id="chk1" onclick="getVal(this)" title="/whatever[^s]*./ Find (whatever) words that ends with (s) or any other combination.">
<input type="checkbox" name="chk" value="/***/" id="chk2" onclick="getVal(this)" title="/***/ Replace *** for specific word to be found.">
<br>
<input type="text" class="column_filter_prospective" name="col12_filter_prospective" id="col12_filter_prospective">
</body>
