如何在Python3中使用selenium驱动点击列表项

Question

I have the following HTML code

<ul id="vmStateDropDown" class="dropdown-content active" style="white-space: nowrap; position: absolute; top: 83px; left: 264px; opacity: 1; display: block;"><li class="waves-effect waves-default" style="display: block;"><a class="" style="cursor: pointer;"><i class="material-icons left" style="cursor: pointer;">directions_run</i><span>Turn On</span></a></li><li class="waves-effect waves-default" style="display: block;"><a class="disabled" disabled="" style="cursor: pointer;"><i class="material-icons left" style="cursor: pointer;">power_settings_new</i><span>Turn Off</span></a></li><li class="waves-effect waves-default" style="display: block;"><a class="disabled" disabled="" style="cursor: pointer;"><i class="material-icons left" style="cursor: pointer;">loop</i><span>Restart</span></a></li></ul>

I need to click in the list item Turn On . Here is the code I have so far.

turn_vmon = driver.find_elements(By.XPATH,'/html/body/div[4]/main/div/div[3]/div[3]/div[1]/ul/li[1]')

When I print the text for turn_vmon variable, I can see the option which I need. However I am unable to figure out how to click on the list item.

Can someone please help?

To click on the element with text as Turn On you can use either of the following Locator Strategy :

• Using xpath :

   driver.find_element(By.XPATH, "//span[text()='Turn On']").click()

---

Ideally to click on the element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following Locator Strategy :

• Using XPATH :

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//span[text()='Turn On']"))).click()

• Note : You have to add the following imports:

   from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC
