Selenium webdriver无法点击页面外部的链接 [英] Selenium webdriver can't click on a link outside the page

问题描述

我遇到Selenium WebDriver的问题。我尝试点击窗口页面之外的链接（您需要向上滚动才能看到它）。我当前的代码是相当标准的：

I am having an issue with Selenium WebDriver. I try to click on a link that is outside the window page (you'd need to scroll up to see it). My current code is fairly standard:

menuItem = driver.findElement(By.id("MTP"));
menuItem.click();
// I also tried menuItem.sendKeys(Keys.RETURN);

我知道我可以向上滚动，在这种情况下可以工作。但是，如果你有一个长列表的项目，你不一定知道你有多远，你必须向下滚动。

I know I could scroll up, and it would work in this case. But in a case where you have a long list of items, you don't necessarily know how far you have to scroll down.

有任何方法可以点击不在页面可见部分的链接（但如果滚动，则会显示该链接）？

Is there any way to click on a link that is not on the visible part of the page (but that would be visible if you scroll)?

注意，我使用的是Firefox，但我打算使用IE7 / 8/9和Chrome。

As a side note, I'm using Firefox, but I am planning to use IE7/8/9 and Chrome as well.

任何帮助将非常感激。

编辑：恐怕我不能给出源代码，因为我工作的公司不允许，但我可以给我想要点击的链接的代码：

I'm afraid I can't give the source code, as the company I work for doesn't allow it, but I can give the code of the link I want to click on:

<div class="submenu">
  <div id="MTP">Link title</div>
</div>

当链接可见时，完全相同的代码工作，只有当它不是不工作。

The exact same code works when the link is visible, only when it is not does it not work.

Edit2：实际上，奇怪的是，它不会引发任何异常，只是转到下一条指令。所以基本上会发生什么：

Actually, oddly enough, it doesn't raise any exception and just goes to the next instruction. So basically, what happens is:

menuItem = driver.findElement(By.id("MTP")); // no exception
menuItem.click();  // no exception
//... some code ensuring we got to the next page: timeout reached
driver.findElement(By.id("smLH")).click(); // NoSuchElementException, as we're on the wrong page.

推荐答案

实际上可以自动滚动到element。虽然这不是一个很好的解决方案（在这种情况下（必须有一种方法，使其工作，而不滚动）我将发布它作为解决方法。我希望有人会想出更好的主意...

It is actually possible to scroll automatically to element. Although this is not a good solution in this case (there must be a way to get it working without scrolling) I will post it as a workaround. I hope someone will come up with better idea...

public void scrollAndClick(By by)
{
   WebElement element = driver.findElement(by);
   int elementPosition = element.getLocation().getY();
   String js = String.format("window.scroll(0, %s)", elementPosition);
   ((JavascriptExecutor)driver).executeScript(js);
   element.click();
}
