Watir 如何获取不同类别的行 [英] Watir How to get rows with different classes

问题描述

我需要获取类名为odd_row"或even_row"的所有行.

I need to get all rows with class named 'odd_row' or 'even_row'.

HTML:

<tbody>
    <tr class="first_row"> … </tr>
    <tr class="subjectField" style="display:none"> … </tr>
    <tr class="odd_row"> … </tr>
    <tr class="subjectField" style="display:none"> … </tr>
    <tr class="even_row"> … </tr>
    <tr class="subjectField" style="display:none"> … </tr>
</tbody>

我试过了:

@b.table(:class => 'color_table').tbody.trs(:class => ('odd_row' || 'even_row').size

但它返回 1.

有人知道如何解决这个问题吗?

Does anybody know how to solve this problem?

推荐答案

如果要对类进行或"，则需要使用正则表达式.在正则表达式中，或"使用单个管道字符|"完成.您想要的类定位器是:

If you want to do an "or" of classes, you need to use a regular expression. In regular expressions, "or" is done using a single pipe character "|". The class locator you would want is:

:class => /odd_row|even_row/

因此，要计算所有奇数行和偶数行，您需要:

Therefore, to count all odd and even rows, you want:

@b.table(:class => 'color_table')
  .tbody
  .trs(:class => /odd_row|even_row/)
  .size
