c# - 如何使用 Selenium 和 C# 单击此特定元素

Question

我已经尝试了很多方法，但似乎都不起作用，它不是一个明确的 id="ezidgrab" 该元素可以在此网址上找到:https://www.ahem.email/mailbox/QI2R89LNDT但我如何用 Selenium 点击那里的电子邮件？

我尝试过的:

1.

driver.FindElement(By.XPath("//p[contains(text(), 'Thank you for registering your email')]")).Click();

2.

driver.FindElement(By.TagName("mat-list-item")).Click();

3.

driver.FindElement(By.ClassName("mat-list-item-content")).Click();

和链接的 html:

<app-email-info _ngcontent-ahem-c5="" _nghost-ahem-c9="">
   <mat-list-item _ngcontent-ahem-c9="" 
                  class="ahem-hand-pointer mat-list-item ahem-email-unread mat-3-line">
      <div class="mat-list-item-content">
         <div class="mat-list-item-ripple mat-ripple" mat-ripple=""></div>
         <div class="mat-list-text">
            <h2 _ngcontent-ahem-c9="" class="mat-line" mat-line="">Jagex</h2>
            <p _ngcontent-ahem-c9="" 
               class="mat-line" 
               mat-line="">Thank you for registering your email</p>
            <p _ngcontent-ahem-c9="" class="mat-line" mat-line="">9 minutes ago</p>
         </div>
         <fa-icon _ngcontent-ahem-c9="" class="ng-fa-icon">

错误:

An unhandled exception of type 'OpenQA.Selenium.NoSuchElementException' occurred in WebDriver.dll no such element: Unable to locate element: {"method":"xpath","selector":"//p[contains(text(), 'Thank you for registering your email')]"}

Answer 1

所需的元素是一个 Angular 元素，因此要在该元素上进行 Click()，您必须为 ElementToBeClickable() 引发 WebDriverWait 并且您可以使用以下任一Locator Strategies:

• CSS选择器:

  new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("div.mat-list-text>h2"))).Click();
  

• XPath:

  new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.XPath("//div[@class='mat-list-text']/h2"))).Click();
