Using CSS selectors to access specific table rows with selenium
提问by wierddemon
If I have the following HTML:
如果我有以下 HTML：
<tbody id="items">
<tr><td>Item 1</td></tr>
<tr><td>Item 2</td></tr>
<tr><td>Item 3</td></tr>
<tr><td>Item 4</td></tr>
<tr><td>Item 5</td></tr>
<tr><td>Item 6</td></tr>
</tbody>
How would I use CSS selectors with Selenium to access Item 4(or really any item I wanted)?
我将如何使用带有 Selenium 的 CSS 选择器来访问项目 4（或我想要的任何项目）？

You can use nth-child selector:
您可以使用第 n 个子选择器：
#items tr:nth-child(4) {color:#F00;}
Live example: https://jsfiddle.net/7ow15mv2/1/
实例：https: //jsfiddle.net/7ow15mv2/1/
But no idea if it works with Selenium.
但不知道它是否适用于 Selenium。
But according to docs it should.
但根据文档它应该。
Currently the css selector locator supports all css1, css2 and css3 selectors except namespace in css3, some pseudo classes(:nth-of-type, :nth-last-of-type, :first-of-type, :last-of-type, :only-of-type, :visited, :hover, :active, :focus, :indeterminate) and pseudo elements(::first-line, ::first-letter, ::selection, ::before, ::after).
目前 css 选择器定位器支持所有 css1、css2 和 css3 选择器，除了 css3 中的命名空间，一些伪类（：nth-of-type，：nth-last-of-type，：first-of-type，：last-of- type, :only-of-type, :visited, :hover, :active, :focus, :indeterminate) 和伪元素(::first-line, ::first-letter, ::selection, ::before, ::后）。

Do you want to select by content ("Item 4")? By Position (the 4st row)? Or is <tr id="foo">and selecting
tr#foo>td
an option?
是否要按内容选择（“项目 4”）？按位置（第 4 行）？或者是<tr id="foo">选择 tr#foo>td 一个选项？

selenium.getText("css=table>tbody[id=items]>tr:nth-child(3)>td(3)");

You could use xpath to find it in a number of different ways but the easiest is:
您可以使用 xpath 以多种不同的方式找到它，但最简单的是：
//td[text()='Item 4']
