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

Question

我正在尝试提交输入(type =按钮).但我无法更新该值.任何帮助表示赞赏.我已附上下面的测试用例供您参考.

它一直是我工作的一个障碍.任何帮助表示赞赏.谢谢

Answer 1

你可以试着替换.click().send_keys("\n"),相当于"在关注元素时按下输入".

所以这:

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

会成为这样的:

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

Answer 2

如果这对于其他任何人来说仍然是一个反复出现的问题,如果您确认您的代码是正确的(您已经检查过它是否有错误等)并且您仍然发现该find_element_by_...('text').click()功能无法正常工作,那通常是因为您的代码继续运行在JavaScript可以更新页面之前.

一个简单的解决方案是import time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.在我的情况下,我用了2秒.希望这会有所帮助.

Answer 3

我会尝试其他元素查找器，例如className,cssSelector或其他东西。如果未找到该元素，xPath 有时不会提供错误。因此，首先要确定 webdriver 是否确实找到了该元素。

您也可以尝试或连续click使用其他命令两次。这已经解决了一些此类问题。
