even selector

version added: 1.0jQuery(':even')

描述： 选择偶数元素，从 0 开始计数。同样查看奇数的

特别地注意的是，这是基于0的索引，所以:even选择器是选择第一个元素，第三个元素，依此类推在匹配。

Example:

Finds even table rows, matching the first, third and so on (index 0, 2, 4 etc.).

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

  table {
    background:#eeeeee;
  }
  </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:even").css("background-color", "#bbbbff");</script>

</body>
</html>
