How can I reliably take away the new lines in a javascript string?

I am trying to remove the new lines in a javascript string. http://jsfiddle.net/muT5V/

However, the alert box produced from this code (jQuery is included) still retains the new lines.

My javascript:

var s = $('#aDivWithContent').html();
s = s.replace('\n', '').replace('\s', '');
alert(s);​

My HTML:

<div id="aDivWithContent">
    <ul>
        <li>foo</li>
        <li>bar</li>
        <li>baz</li>
    </ul>
</div>​

Why?

The Reason is, that replace() only replaces ONE found. If you use a RegEx as first parameter from replace(), then all found results will be replaced.

var s = $('#aDivWithContent').html();
s = s.replace(new RegExp("\n", "g"), 'a');
s = s.replace(new RegExp("\s", "g"), 'b');

alert(s);

You need RegExp with g option and \r cleanup

var r = new RegExp("\r", "g");

var n = new RegExp("\n", "g");

str = str.replace(r,'').replace(n,'');

Try:

s = s.replace(/(\r\n|\n|\r|\t|\s)/gm,"");
