java如何在类中定位特定按钮。该按钮可能与该类之外的其他按钮共享类名

Question

这是具有classname操作的按钮。我怎么能只指向这个snackbar类中的这个按钮呢。我需要xpath

<div class="snackbar-container  snackbar-pos bottom-center" style="width: 475px; background: rgb(50, 50, 50); opacity: 1;" xpath="1">
   <p style="margin: 0px; padding: 0px; color: rgb(255, 255, 255); font-size: 14px; font-weight: 300; line-height: 1em;">Show similar patients for  Jerry Rocker</p>
   <button class="action" style="color: rgb(76, 175, 80);">SHOW</button>
</div>

试过这个。 网络元素

snackbarButton=driver.findElement(By.xpath("//button[contains(@class,'action') and contains(@class,'snackbar-pos']"));

---

    <div class="snackbar-container  snackbar-pos bottom-center" style="width: 475px; background: rgb(50, 50, 50); opacity: 1;" xpath="1">
       <p style="margin: 0px; padding: 0px; color: rgb(255, 255, 255); font-size: 14px; font-weight: 300; line-height: 1em;">Show similar patients for  Jerry Rocker</p>
       <button class="action" style="color: rgb(76, 175, 80);">SHOW</button>
    </div>

Answer 1

如果你想得到按钮，它是^{}标记的子元素，而^{} attribute包含snackbar-pos，你可以使用以下表达式：

//div[contains(@class,'snackbar-pos')]/button

演示：

然而，坚持这一点可能更有意义：

//div[@xpath='1']/button

甚至这个Jerry Rocker文本：

//p[contains(text(),'Jerry Rocker')]/following-sibling::button

Answer 2

您可以使用下面给定的xpath

//div[@class='snackbar-container  snackbar-pos bottom-center']//child::p//following-sibling::button[@class='action']

希望这能有所帮助

Answer 3

假设您打算点击按钮，文本为SHOW，与文本为的元素关联，为Jerry Rocker显示类似的患者，并实现诱导WebDriverWait使元素可点击，您可以使用以下任一Locator Strategies：

• xpath1

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//p[text()='Show similar patients for  Jerry Rocker']//following::button[1]"))).click();
  

• xpath2

  new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//p[text()='Show similar patients for  Jerry Rocker']//following::button[@class='action' and text()='SHOW']"))).click();
