 WebDriverWait wait = new WebDriverWait(driver, 10);
  wait.until(ExpectedConditions.elementToBeClickable(driver.findElement(By.linkText("E-Commerce Demo Site"))));
  driver.findElement(By.linkText("E-Commerce Demo Site")).click();

driver.findElement(By.cssSelector("#main-nav > li.menu-item.menu-item-type-custom.menu-item-object-custom.menu-item-has-children.menu-item-17611.dt-mega-menu.mega-auto-width.mega-column-1.has-children > ul > li.menu-item.menu-item-type-custom.menu-item-object-custom.menu-item-21575.dt-mega-parent.wf-1.first.level-arrows-on")).click();

Answer 1

     Actions ac;
 ac = new Actions(dr);
ac.MoveToElement(dr.FindElement(By.LinkText("DEMOSITES"))).Perform();

然后使用以下任意 xpath 单击子菜单:

1."//span[contains(text(),'电子商务演示站点')]"

2."//a[@href=' http://store.demoqa.com ']"

dr.findelement(By.xpath(xpath)).click();
