我无法切换到timesofindia站点中的帧（包含5+5）并获得NoSuchElementException。请帮助我，因为我是硒的新手

Answer 1

框架似乎是：

<iframe id="mailroifrm12" width="300" scrolling="no" align="left" height="223" frameborder="0" src="/poll.cms" marginwidth="0" marginheight="0" hspace="0" vspace="0" valign="top">

所以试着：

    WebElement  element=driver.findElement(By.id("mailroifrm12"));
    driver.switchTo().frame(element);
    WebElement  form =driver.findElement(By.xpath("//form[@name='pollform']"));
    // do stuff
