使用Python绑定，Selenium WebDriver click（）有时不起作用。

Question

我试图提交一个输入（type=button），但无法更新该值。 如有任何帮助，我们将不胜感激。 我附上了下面的测试用例供您参考。

它一直是我工作的一大亮点。谢谢你的帮助。谢谢

Answer 1

您可以尝试用..click()替换send_keys("\n")，这相当于“在聚焦元素时按enter”。

所以这个：

driver.find_element_by_link_text('PurchaseOrder').click()

会变成这样：

driver.find_element_by_link_text('PurchaseOrder').send_keys("\n")

Answer 2

如果这对其他人来说仍然是一个重复出现的问题，那么如果您已经确认了代码是正确的（您已经检查过错误等），并且仍然发现find_element_by_...('text').click()函数不能正常工作，这通常是因为您的代码在JavaScript更新页面之前继续运行。

一个简单的解决方案是import time，然后在任何click()方法之后立即插入以下代码：

time.sleep(2) 

睡眠计时器的持续时间可以是您选择的任何时间。我用了2秒。希望能有所帮助。

Answer 3

我也有这个问题。有时，无论出于什么原因，webdriver都没有单击按钮。它能够找到按钮（它没有抛出NoSuchElementException，WebDriverWait也没有帮助）。

两次单击按钮的问题是，如果第一次单击成功，第二次单击将失败（或者如果找到匹配项，请单击下一页上的提交按钮！）。我的第一次尝试是将第二次单击放在try/except块中-这就是我在下一页单击submit找到它的方式。XD和它还真的减慢了我的测试时，它找不到第二个按钮。

我在Selenium 2.0b3 IE WebDriver, Click not firing找到了一些好的见解。基本上，我首先单击父元素，它似乎什么也不做。然后我点击提交按钮。
