Answer 1

e.g

$("#inputId").toggle(
      function () {
        $(this).addClass('someClass');
      },
      function () {
        $(this).addClass('differentClass');
      }
);

Answer 2

HTML：

<input id="MyButton" type="button" value="Click me" class="Color1" />

JQuery的：

<script type="text/javascript">
    $(document).ready(function() {
        $("#MyButton").click(function() {
            if ($(this).attr("class") == "Color1") {
                $(this).attr("class", "Color2");
            }
            else {
                $(this).attr("class", "Color1");
            }
        });
    });
</script>
