odd selector

version added: 1.0jQuery(':odd')

描述： 选择奇数元素，从 0 开始计数。同样查看偶数

特别地注意的是，这是基于0的索引，所以:odd选择器是选择第二个元素，第四个元素，依此类推在匹配。

Example:

Finds odd table rows, matching the second, fourth and so on (index 1, 3, 5 etc.).

<!DOCTYPE html>
<html>
<head>
  <style>

  table {
    background:#f3f7f5;
  }
  </style>
  <script src="http://code.jquery.com/jquery-latest.min.js"></script>
</head>
<body>
  <table border="1">
    <tr><td>Row with Index #0</td></tr>
    <tr><td>Row with Index #1</td></tr>

    <tr><td>Row with Index #2</td></tr>
    <tr><td>Row with Index #3</td></tr>
  </table>
<script>$("tr:odd").css("background-color", "#bbbbff");</script>

</body>
</html>
