Q1583 How can I replace all non alphanumeric characters from a string?

Use a regular expression:

<script language="JavaScript"><!--
var temp = new String('This is a test string... So??? What...');
document.write(temp + '<br>');
temp = temp.replace(/[^a-zA-Z 0-9]+/g,'');
document.write(temp + '<br>');
//--></script>
