guys!

How can I catch the text from a javascript alert and set a OK using chrome headless? The follow code works very well, but if I set headless option it seems not find the pop up alert.

Edit I realize that my code stops on " self.action.move_to_element(firstLevelMenu).perform() ", instead on javascript alert like I thought. How can I fix it?

        # options.add_argument("--headless")
        options.add_argument("--dns-prefetch-disable")

self.driver = webdriver.Chrome('c:/driver/chromedriver.exe', options=options) #PASTA DO SCRIPT

    self.log.write(f'ID;Chpras;Bin;Final;Portador;Status')

    self.login = in_login.get()
    self.senha = in_senha.get()

    self.retorna_frame()
    
    firstLevelMenu = self.driver.find_element(By.XPATH, '//*[@id="imgMenu"]')
    self.action.move_to_element(firstLevelMenu).perform() #menu opções

    pausa.sleep(0.5)

    #### THE PROBLEM STARTS RIGHT HERE!!!!!!!!!!!!!!!!!!!!!!!!
    #there's 2 alerts. On the first one I need set an accept

    alert1 = self.wait.until(EC.alert_is_present())
    
    alert1.accept()
    
    
    pausa.sleep(0.5)
    try:
        # on the second one I need cacth the text and set another "ok"
        alert2 = self.wait.until(EC.alert_is_present())
        
        text = alert2.text
        
        alert2.accept()        
        
        print(text)
        
        
        if 'BLOQU' in str(text).upper():
            text = self.captura_msg_bloqueio(chpras)
        
        self.log.write(f'{text};')
        
            
    except:
        self.log.write(f'Não foi possível capturar a mensagem de retorno;')
        self.driver.close()
            
    self.aceita_alerta()
    self.driver.switch_to.window(self.driver.window_handles[1])

    pausa.sleep(0.5)

I really need use the headless option, and I need load/accept the both pop up alerts. How I do this?

CodePudding user response：

You can overwrite alert to catch the message:

driver.executeScript("""
  window.alert = message => window.alertMessage = message
""")

Then get it later

message = driver.executeScript("return window.alertMessage")
