No.

1
if you mean a regular expression with "r"
you should specify with what it is replaced with.

var resultString = sourceString.replace(regExpression, withString);

2
the functions returns a new string with the result, 
the original string being unaltered. 
So, if you want the originals string altered, 
you should assign the result to that same variable:


================================
<script type='text/javascript'>

var myString = 'abcabc';
myString = myString.replace(/a/,'X');
document.write(myString); // shows: Xbcabc

document.write('<br>');

var myString2 = 'abcabc';
myString2 = myString2.replace(/a/g,'Y');
document.write(myString2); // shows: YbcYbc

document.write('<br>');

var myString3 = 'abcAbc';
myString3 = myString3.replace(/a/g,'Z');
document.write(myString3); // shows: ZbcAbc

document.write('<br>');

var myString4 = 'abcAbc';
myString4 = myString4.replace(/a/gi,'Z');
document.write(myString4); // shows: ZbcZbc

</script>
================================
