Question

<a href="MappingAndEnrichmentSetUp.aspx" title="Mapping &amp; Enrichment" class="rpLink rpExpandable  rpSelected" target="ctl00_DefaultContent_radPaneProjectMaintContent">
    <span class="rpOut rpNavigation">
        <span class=""></span>
        <span class="rpText" style="">Mapping &amp; Enrichment</span>
    </span>
</a>

这是我从控制台获得的信息

a=$x("//a[@title='Mapping & Enrichment']")

输出：

[a.rpLink.rpExpandable]

在索引0处具有链接和隐藏的照片元素

a[0].click()  --works fine

a-返回数组

是否可以使用xpath直接获取上述html代码段的锚标记？

我在java testNG类中使用以下代码来单击链接。它不起作用。

控制台调试：

a=$x("(//a[@href='ProjectDimensionSetUp.aspx'])")
[a.rpLink]
  0: a.rpLinklength: 
  1__proto__: Array(0)

a=$x("(//a[@href='ProjectDimensionSetUp.aspx'])")[0]
<a href="ProjectDimensionSetUp.aspx" title="Project Dimensions" class="rpLink" target="ctl00_DefaultContent_radPaneProjectMaintContent">…</a>

是否可以通过xpath直接选择元素？这样，我可以使用testNG Java WebElement中的a.click（）

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("XPATH_TO_SELECT_ANCHOR_TAG_NOT_ARRAY_WITH_ANCHOR_TAG"))).click();

Answer 1

根据您提供的HTML来调用 link 上的click()，文本为 Mapping＆Enrichment （映射和丰富化），您需要诱导 WebDriverWait 以使所需的元素可点击，您可以使用以下解决方案：

new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//a[@class='rpLink rpExpandable  rpSelected' and @href='MappingAndEnrichmentSetUp.aspx']/span[@class='rpOut rpNavigation']//span[@class='rpText']"))).click();

Answer 2

从我们在评论中的对话看来，您似乎在混淆两件事。

在浏览器控制台中，执行$x()返回一个元素集合，因此$x().click()不起作用，因为您无法单击整个集合。如果使用数组符号，则可以指定要单击的集合的成员，例如$x()[0].click()将单击集合中的第一个元素。

要将其转换为Java / Selenium，driver.findElements()（复数）与$x()等效，因为它们都返回元素的集合。如果使用driver.findElement()（单数），则即使位于多个元素中，它也仅返回第一个元素。因此，即使使用的定位器找到了多个元素，您也可以安全地使用driver.findElement().click()。

如果您想使用返回多个元素但不希望仅获取第一个元素的定位符，则可以使用.get(x)，其中x是您想要的元素在索引中的索引采集。例如，driver.findElements().get(1)将返回 second 元素（0是第一个元素的索引，1是第二个元素的索引，依此类推）。

无法通过xpath选择和单击链接锚标记，它返回一个包含1个元素的数组
