Selenium/Python - 如何点击 onclick() 按钮

Question

I am trying to find and click with selenium on python a little plus-button but for any reason I a get a TypeError

TypeError: 'str' object is not callable

This is the link https://meshb.nlm.nih.gov/treeView and I try to find and click the following codesnippet from the html.

<i id="plus_Anatomy" onclick="openTree(this)" class="fa fa-plus-circle treeCollapseExpand fakeLink"></i>

This is my python code so far. At first it looks like everything should work. So browser windows opens and the webpage is loaded, but then I get this error mentioned above.

from selenium import webdriver
from selenium.webdriver.common.by import By

driver = webdriver.Chrome()
driver.get("https://meshb.nlm.nih.gov/treeView")
plus = driver.find_element(By.CLASS_NAME('fakeLink'))
driver.execute_script("arguments[0].click();", plus)

The bigger goal is to click on all the buttons and scrap the complete html in the end. can anybody please help me? What am I doing wrong?

Answer 1

You have a syntax error.
Instead of

plus = driver.find_element(By.CLASS_NAME('fakeLink'))

Try

plus = driver.find_element(By.CLASS_NAME, 'fakeLink')

Or even

driver.find_element(By.CLASS_NAME, 'fakeLink').click()
