"Unable to locate element" before I click on new browser window-CodePudding

I try to click on the element with the class name "mat-select-arrow-wrapper.ng-tns-c73-7" on the website below. This causes the error "Unable to locate element" until I click the new browser window once, how can I get around this? The other two boxes to the left of this do not exhibit the problem.

My code currently looks like this:

url = "https://www.pamyra.de/"

driver = webdriver.Chrome(ChromeDriverManager().install())
driver.get(url)
time.sleep(3)

driver.find_element_by_class_name("mat-select-arrow-wrapper.ng-tns-c73-7").click()

CodePudding user response：

You have css selector .mat-select-arrow-wrapper.ng-tns-c73-7 and you are causing by_class_name is the reason why you are getting the exception.

Please use below code :

driver.find_element_by_css_selector(".mat-select-arrow-wrapper.ng-tns-c73-7").click()

Full code should look like this :

driver = webdriver.Chrome(ChromeDriverManager().install())
driver.implicitly_wait(30)
driver.maximize_window()

url = "https://www.pamyra.de/"

driver.get(url)
time.sleep(3)

driver.find_element_by_css_selector(".mat-select-arrow-wrapper.ng-tns-c73-7").click()

Update 1 :

With Explicit waits :

driver = webdriver.Chrome(driver_path)
driver.maximize_window()
driver.implicitly_wait(30)
wait = WebDriverWait(driver, 30)

url = "https://www.pamyra.de/"

driver.get(url)
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div#mat-select-value-5 div"))).click()
