JavaScript 警示、提示和確認訊息

WebDriver 提供了一個 API，用於處理 JavaScript 提供的三種原生彈出訊息類型。這些彈出視窗由瀏覽器設定樣式，並且自訂程度有限。

警示

其中最簡單的一種稱為警示，它顯示自訂訊息和一個按鈕，該按鈕會關閉警示，在大多數瀏覽器中標記為「確定」。它也可以在大多數瀏覽器中通過按關閉按鈕來關閉，但這將始終執行與「確定」按鈕相同的操作。查看警示範例。

WebDriver 可以從彈出視窗中取得文字，並接受或關閉這些警示。


        Alert alert = driver.switchTo().alert();
        //Store the alert text in a variable and verify it
        String text = alert.getText();
        assertEquals(text, "Sample Alert");
        //Press the OK button
        alert.accept();

    element = driver.find_element(By.LINK_TEXT, "See an example alert")
    element.click()

    wait = WebDriverWait(driver, timeout=2)
    alert = wait.until(lambda d : d.switch_to.alert)
    text = alert.text
    alert.accept()

//Click the link to activate the alert
driver.FindElement(By.LinkText("See an example alert")).Click();

//Wait for the alert to be displayed and store it in a variable
IAlert alert = wait.Until(ExpectedConditions.AlertIsPresent());

//Store the alert text in a variable
string text = alert.Text;

//Press the OK button
alert.Accept();
  
    # Store the alert reference in a variable
    alert = driver.switch_to.alert

    # Get the text of the alert
    alert.text

    # Press on Cancel button
    alert.dismiss

//Click the link to activate the alert

//Wait for the alert to be displayed and store it in a variable
val alert = wait.until(ExpectedConditions.alertIsPresent())

//Store the alert text in a variable
val text = alert.getText()

//Press the OK button
alert.accept()

確認

確認方塊類似於警示，但用戶也可以選擇取消訊息。查看確認範例。

此範例也示範了儲存警示的不同方法


        alert = driver.switchTo().alert();
        //Store the alert text in a variable and verify it
        text = alert.getText();
        assertEquals(text, "Are you sure?");
        //Press the Cancel button
        alert.dismiss();
在 GitHub 上查看完整範例
    element = driver.find_element(By.LINK_TEXT, "See a sample confirm")
    driver.execute_script("arguments[0].click();", element)

    wait = WebDriverWait(driver, timeout=2)
    alert = wait.until(lambda d : d.switch_to.alert)
    text = alert.text
    alert.dismiss()
在 GitHub 上查看完整範例
//Click the link to activate the alert
driver.FindElement(By.LinkText("See a sample confirm")).Click();

//Wait for the alert to be displayed
wait.Until(ExpectedConditions.AlertIsPresent());

//Store the alert in a variable
IAlert alert = driver.SwitchTo().Alert();

//Store the alert in a variable for reuse
string text = alert.Text;

//Press the Cancel button
alert.Dismiss();
  
    # Store the alert reference in a variable
    alert = driver.switch_to.alert

    # Get the text of the alert
    alert.text

    # Press on Cancel button
    alert.dismiss

wait.until(ExpectedConditions.alertIsPresent())

//Store the alert in a variable
val alert = driver.switchTo().alert()

//Store the alert in a variable for reuse
val text = alert.text

//Press the Cancel button
alert.dismiss()

提示

提示類似於確認方塊，不同之處在於它們還包含文字輸入。與使用表單元素類似，您可以使用 WebDriver 的 send keys 來填寫回應。這將完全替換佔位符文字。按下取消按鈕將不會提交任何文字。查看提示範例。


        alert = driver.switchTo().alert();
        //Store the alert text in a variable and verify it
        text = alert.getText();
        assertEquals(text, "What is your name?");
        //Type your message
        alert.sendKeys("Selenium");
        //Press the OK button
        alert.accept();
