如何通过Selenium / Python选择没有ID的Web元素

Question

I'm trying to select an element on the minehut.com webpage that has no ID. Everything I've found says to use a CSS Selector, which hasn't been working

The element I'm trying to select is:

 <button _ngcontent-c17 color="Primary" mat-raised-button class="mat-raised-button mat-primary" style="margin-right: 10px;"> 

Code:

 from selenium import webdriver from selenium.webdriver.common.keys import Keys #Initialize the driver and connect to the website driver = webdriver.Chrome() driver.get('https://minehut.com/panel/login') #Log in driver.find_element_by_id('mat-input-0').send_keys(<Username>) driver.find_element_by_id('mat-input-1').send_keys(<Password> + Keys.RETURN) #Here is the css call for i in driver.find_elements_by_css_selector("button[color='Primary']"): print(i) driver.close() 

Ultimately the code will be paired with a discord bot to start/stop a minecraft server (among other server features) This part is attempting to find the Start button, and potentially put it in a variable

fixed a syntax error

replacing driver.find_elements_by_css_selector() with driver.find_elements_by_xpath() works perfectly. The answer explains how to find the xpath of a web element Thanks.

Answer 1

有很多方法可以定位元素，xpath，css，id，tagNames，此处在CSS中的外观可能是这样， css= button[color='Primary']但是，如果还有其他具有相同标识符的按钮，则可能会出现问题。

Answer 2

One potential thing you can try is selecting via the xpath, you can download a chrome extension called xpath finder, and then hover over the desired element to get the xpath, and then attempt to interact with it by doing:

driver.find_element_by_xpath(x_path_of_the_element)

I hope that works for you.

Answer 3

您可以使用css选择器，更正您的选择器：

driver.find_elements_by_css_selector('button[color="primary"]')

Answer 4

You may have to switch frames if there are multiple frames. If not, you can try driver.find_element_by_xpath(xpath_of_element) . In order to get the xpath, you can inspect the element and then right click on the highlighted text in the elements and click Copy>Copy XPath
