Selenium WebDriver-使用cssSelector和第n个子元素查找元素 [英] Selenium WebDriver - Finding Elements using cssSelector and nth child

问题描述

<ul>
<li class="active">
    <a href="#">
    <i class="fa fa-home"></i><br>
    <span class="title">Home</span>
    </a>
</li>

<li>
    <a href="#">
    <i class="fa fa-rss-square"></i><br>
    <span class="title">Posts</span>
    </a>
</li>

<li>
    <a href="#">
    <i class="fa fa-calendar"></i><br>
    <span class="title">Events</span>
    </a>
</li>

<li>
    <a href="#">
    <i class="fa fa-bar-chart-o"></i><br>
    <span class="title">My Activity</span>
    </a>
</li>

<li>
    <a href="#">
    <i class="fa fa-edit"></i><br>
    <span class="title">Assessments</span>
    </a>
</li>
</ul>

我想找到相应的span元素.我想使用css选择器检查span元素的顺序.因此，当我使用Selenium IDE时，我将按照以下方式进行验证(使用第n个子概念).

I want to locate the respective span element. I want to check the order of the span elements using css selector. So when I use selenium IDE,I will verify it like below(using nth child concept).

verifyText | css = .title:nth(0)|主页
verifyText | css = .title:nth(1)|帖子
verifyText | css = .title:nth(2)|活动
verifyText | css = .title:nth(3)|我的活动
verifyText | css = .title:nth(4)|评估

verifyText | css=.title:nth(0) | Home
verifyText | css=.title:nth(1) | Posts
verifyText | css=.title:nth(2) | Events
verifyText | css=.title:nth(3) | My Activity
verifyText | css=.title:nth(4) | Assessments

但是，当我在Selenium WebDriver中执行相同的操作时，我无法按照我使用Selenium IDE进行的顺序来定位元素.

But when I do the same thing in Selenium WebDriver I am not able to locate the elements with the order which I did using Selenium IDE.

下面是我在WebDriver中使用的代码，它可以正常工作.

Below are the codes that I used in WebDriver and it dint work.

driver.findElement(By.cssSelector(".title:nth(0)")); // to locate the "Home" element

driver.findElement(By.cssSelector(".title:nth-of-type(0)")); // to locate the "Home" element

driver.findElement(By.cssSelector(".title:nth-child(0)")); // to locate the "Home" element

任何人都可以帮助我.

推荐答案

您可以像ul > li:nth-child(1)这样从ul生成css选择器.见下文:

You can generate the css-selector from ul like ul > li:nth-child(1) for home. See below:

driver.findElement(By.cssSelector("ul > li:nth-child(1)")); >> home
driver.findElement(By.cssSelector("ul > li:nth-child(2)")); >> posts
driver.findElement(By.cssSelector("ul > li:nth-child(3)")); >> events

作用范围也相同:

driver.findElement(By.cssSelector("ul > li:nth-child(1) > a > span")); >> home
