Hi I have a question, it's probably very basic but I'm still learning the Javascript basics.
The following form outputs a string change (from "input" to "text" box ). When the word "test" is inputted, it changes to "good".
Simple question: If there is no matching string, how would I get the form to just display nothing at all?
Thanks!

<html>
<head>
<center>
<script type = "text/javascript">
function replaceChars() {
var temp = document.subform.input.value;
temp = temp.replace(/test/gi, "good");
temp = temp.replace (/hello/gi, "bad");
temp = temp.replace (/today/gi, "tomorrow");
document.subform.text.value = temp;
}
</script>

<form name="subform">
