OpenQA.Selenium.UnhandledAlertException：模式对话框显示错误消息

Question

我正在附加代码以及应用程序的屏幕截图。我有这个提示窗口，需要输入文本。 Page对象包含有关页面的所有必需信息，但脚本失败，因为它无法识别提示窗口。

            return this;

        }

        public CashLoadingHo CashLoadingDetails(String merchantid, String cashloadtype, String customeraccountnumber, String payment, string amount, string nameofthedepositor)

                   .EnterText(txtNameofDepositor, nameofthedepositor);

                   .AcceptAlert();
            return this;
        }

        public CashLoadingHo EnterCarrierId(string entercarrierid)

Answer 1

使用driver.SwitchTo().Alert().SendKeys(/* The text to send to the alert textbox*/);

切换到您的提醒

然后只需使用driver.SwitchTo().Alert().Accept();

接受它

或者您可以从头开始关闭driver.SwitchTo().Alert().Dismiss();

您可以修改保存功能以输入您的运营商ID，但我会建议不要这样做，因为即使您只想“保存”，也必须输入运营商ID。也许在某些时候，您可以单击“保存”并且不会显示警报。

public CashLoadingHo ClickSave()
{
    wrapper.Click(btnSave)
           .AcceptAlert();
    return this;
}

public CashLoadingHo AlertEnterCarrierId(string id)
{
    WaitForAlert(); //Explained below
    driver.SwitchTo().Alert().SendKeys(id);
    driver.SwitchTo().Alert().Accept();
    //Now, swap back to your main window.
    driver.SwitchTo().DefaultContent();
    return this;
}

public CashLoadingHo AlertEnterAmount(string amount)
{
    WaitForAlert(); //Explained below
    driver.SwitchTo().Alert().SendKeys(amount);
    driver.SwitchTo().Alert().Accept();
    //Now, swap back to your main window.
    driver.SwitchTo().DefaultContent();
    return this;
}

然后，一个接一个地调用3个函数。但是，根据我的经验，您应该等待警报出现，这样您就不会因警报不存在而获得异常。创建一个等待函数，其他2（处理警报的两个函数）将调用。

public CashLoadingHo WaitForAlert()
{
    //Initialize your wait object.
    WebDriverWait wait = new WebDriverWait(driver,TimeSpan.FromSeconds(10));
    wait.Until(ExpectedConditions.AlertIsPresent());
    return this;
}

Answer 2

简单，首先切换到提示警报driver.SwitchTo().Alert()，然后使用.sendKey()传递值/文本，最后，使用.Accept()接受提示警报

请尝试以下代码

//This step produce an alert on screen
IWebElement element = driver.FindElement(By.XPath("//*[@id='content']/p[11]/button"));

// 'IJavaScriptExecutor' is an 'interface' which is used to run the 'JavaScript code' into the webdriver (Browser)        
((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].click()", element);

// Switch the control of 'driver' to the Alert from main window
IAlert promptAlert = driver.SwitchTo().Alert();

// Get the Text of Alert
String alertText = promptAlert.Text;
Console.WriteLine("Alert text is " + alertText);

//'.SendKeys()' to enter the text in to the textbox of alert 
promptAlert.SendKeys("Accepting the alert");
Thread.Sleep(4000); //This sleep is not necessary, just for demonstration

// '.Accept()' is used to accept the alert '(click on the Ok button)'
promptAlert.Accept();
