    <script type="text/javascript">
        function removeWhitespaces() {
            var txtbox = document.getElementById('txtOne');
            txtbox.value = txtbox.value.replace(/\s/g, "");
        }
    </script>
</head>
<body>
    <input id="txtOne" type="text" /><br />
    <input id="btnRemoveWs" type="submit"
    value="Remove Whitespaces" onclick="removeWhitespaces()" />
</body>
</html>

The "g" stands for "global" which replaces all white space matches (front, trailing and in between)
