I have a script where I can PregReplace something in a string with a defined value from my input field and it works like a charm.

PHP Code:
echo '<input id="pfrom" type="text" value="" name="pfrom">'
Code JavaScript:
function demoRegex(){
	var txt = document.newform.thestring.value;
	var re = new RegExp(document.newform.pfrom.value, "g");
	newtxt = txt.replace(re,'');
	alert(newtxt);
}

But what if I have multiple input field like this:
PHP Code:
foreach($arr as $arr1=>$value){
    echo 
'<input id="pfrom" type="text" value="" name="pfrom[]">';

How do I get the javascript to run through all the fields?

Hoping for help.... Thanks in advance ;-)
