无法使用python在硒中使用CSS_SELECTOR定位元素
[英]Unable to locate the element using CSS_SELECTOR in selenium using python
问题描述
I've been trying to locate and click() a javascript rendered image. 
我一直试图找到并单击（）一个JavaScript渲染图像。 Using css_selector I'm able to locate the element, however, I have to hover over the 1st element of the table in order to capture the location of the image. 使用css_selector我可以找到该元素，但是，我必须将鼠标悬停在表的第一个元素上才能捕获图像的位置。

Now, I need to click on the 7th child of the first row, which changes dynamically. 现在，我需要单击第一行的第7个子项，该子项会动态更改。 First, It will be a different image and after processing, it will be a PNG button which can be clicked and the reports can be downloaded. 首先，它将是一个不同的图像，经过处理后，它将是一个PNG按钮，可以单击该按钮并可以下载报告。
By using the code below I was able to find the required element. 通过使用下面的代码，我能够找到所需的元素。 However, I had to manually hover over the first row in order to do so. 但是，我必须手动将鼠标悬停在第一行上。 Additionally, If I hover over 2nd or 3rd row accidentally, content of 2nd and 3rd row will be downloaded instead of first. 另外，如果我不小心将鼠标悬停在第二行或第三行上，则会下载第二行和第三行的内容，而不是第一行。
WebDriverWait(driver, 60).until(EC.element_to_be_clickable((By.CSS_SELECTOR, ".GPBYFDEKG:nth-child(7) img"))).click()
Is there any way I can click on the 7th child of first row whithout manually hover over it? 有什么方法可以单击第一行的第7个孩子，而无需手动将鼠标悬停在它上面？

I'm not sure it will work in Python or not but you can try the below XPaths: 我不确定它是否可以在Python中运行，但是您可以尝试以下XPath：
//tr[@__gwt_row='0']/td[last()]
or 要么
(//tr[@__gwt_row='0']/td)[7]
