我有以下HTML代码

我正在尝试从上面的html代码中找到id为WelcomeMessage的span元素。我尝试了以下方法来找到

driver.switchTo().frame("welcomeMain");
WebElement element=driver.findElement(By.xpath(".//*[@id='WelcomeMessage']");

请告诉我如何在框架集/框架之间切换[如果是复杂的html与如上所示的复杂框架]并在其中找到元素。

我收到错误“无法找到元素welcomeMain ......”

请提前感谢，请回复此事。

这可能是问题，因为您的webdriver控件可能已经在默认框架内，并且您可能需要先将控件从所有框架中取出，然后再将其转移到另一个框架。

使用以下代码检查您是否能够切换到该页面中的所有可用框架，这应该可以正常工作。

    for (WebElement e :driver.findElements(By.tagName("frame")))
    {
        driver.switchTo().defaultContent();
        driver.switchTo().frame(e);

        if(driver.findElement(By.xpath("yourElement")).isDisplayed())
        {
            driver.findElement(By.xpath("yourElement")).click();
            break;
        }
        else
            continue;
    }

使用selenium Webdriver在Html中定位框架集内的元素
