使用Python绑定时，Selenium WebDriver的click()有时不起作用。
我正在尝试提交一个输入框（类型是按钮），但是我无法更新它的值。希望能得到一些帮助。下面是我附上的测试案例，供你参考。

这对我的工作造成了很大的困扰。任何帮助都非常感谢。谢谢！

我也遇到过这个问题。有时候，不知道为什么，webdriver就是不点击按钮。它能找到按钮（没有抛出“NoSuchElementException”错误，使用“WebDriverWait”也没用）。
点击按钮两次的问题是，如果第一次点击成功，第二次就会失败（或者如果找到了匹配项，就会点击下一个页面的提交按钮！）。我第一次尝试是在一个try/except块里放第二次点击——这让我发现它在下一个页面上点击了提交按钮。XD 而且当找不到第二个按钮时，这样做真的让我的测试变得很慢。
我在Selenium 2.0b3 IE WebDriver, Click not firing上找到了不错的见解。基本上，我先点击一个父元素，虽然看起来没什么反应。然后我再点击提交按钮。

如果这个问题还在困扰其他人，首先确认你的代码是正确的（检查过有没有错误等），但发现 find_element_by_...('text').click() 这个功能还是不正常，通常是因为你的代码在JavaScript更新页面之前就已经继续运行了。
一个简单的解决办法是 import time，然后在任何 click() 方法后面插入下面的代码：
time.sleep(2)
你可以根据需要设置休眠的时间。在我的例子中，我用了2秒。希望这能帮到你。

你可以试着把 .click() 换成 .send_keys("\n")，这就相当于“在某个元素上按下回车键”。
所以这个：
driver.find_element_by_link_text('PurchaseOrder').click()
就变成这个：
driver.find_element_by_link_text('PurchaseOrder').send_keys("\n")
