我想点击"按钮"下面,但无法点击它。
html是:
<table onclick="filtersJob_intrinsic_extender.addRow();return false;" class="FilterList_addLink">
<tbody>
<tr>
<td class="icon"><img src="/commander/lib/images/icn12px_add.gif" alt="Add Filter"></td>
<td class="text">Add Intrinsic Filter</td>
</tr>
</tbody>
</table>
我基本上是用watir和watir-webdriver做的:
browser.td(:text => 'Add Intrinsic Filter').click
我在另一个网站上的另一个类似按钮上尝试了这个方法并且它有效。我想知道为什么它在这里不起作用。
它导致异常:
Selenium::WebDriver::Error::ElementNotVisibleError in 'your rspec spec code'

从评论中我们看到实际上有51个td元素有“Add Intrinsic Filter”文本:
browser.tds(:text => 'Add Intrinsic Filter').length
#=> 51
我们也看到其中一些单元格是可见的而有些则不是 - 即在为每个单元格调用.visible?
时,某些单元格返回true而其他单元格返回false:
browser.tds(:text => 'Add Intrinsic Filter').map(&:visible?).uniq
#=> [false, true]
当找到单个元素时,Watir将选择匹配的第一个元素。在这种情况下,我们可以推断出第一个带有文本“Add Intrinsic Filter”的单元格是不可见的:
* Selenium :: WebDriver :: Error :: ElementNotVisibleError异常是不可见的。
*根据browser.tds(:text => 'Add Intrinsic Filter').map(&:visible?).uniq
结果的排序,第一个元素不可见。
如果没有看到该页面,我们只能假设第一个匹配的单元格不是您实际想要点击的单元格。

您需要确定51个单元格中的哪一个实际上是您要单击的单元格,然后使用更具体的定位器。
根据Selenium IDE的结果,你可以这样做:
browser.td(:xpath => '//tr[@id="filtersJob_intrinsic_container"]/td[2]/table[2]/tbody/tr/td[2]').click
指定元素的整个路径可能很容易发生变化,因此您可能希望尝试一些不那么具体的东西。也许尝试找到具有特定id的行,然后查找具有特定文本的单元格:
browser.tr(:id => 'filtersJob_intrinsic_container').td(:class => 'text', :text => 'Add Intrinsic Filter').click
请注意,:class
被添加为定位器以尝试获取内部td而不是外部td。
