Swap class with jQuery

Question

Can I use jQuery to replace certain class (.a) in input fields with another (.b) one in my table?

<table id="myTable">
<tr>
    <td>Field 1</td>
    <td><input type="text" class="a"></td>
</tr>
<tr>
    <td>Field 2</td>
    <td><textarea class="a"></td>
</tr>
</table>

Answer 1

$("#myTable").find(":input").removeClass('a').addClass('b');
