java - 为什么不弹出警报？

Question

我试着把它放在代码中。

driver.findElement(By.xpath("//*[@id='adduser']/div/form/div[2]/div/div/label")).click();
Thread.sleep(1000);

Alert alert = driver.switchTo().alert();
String alertMessage = driver.switchTo().alert().getText();
System.out.println(alertMessage);
alert.accept();

我发现了“没有警报”之类的错误消息。

完整的 Java 代码如下..

package AddUser;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.NoAlertPresentException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.FluentWait;
import org.openqa.selenium.support.ui.Select;
import org.openqa.selenium.support.ui.WebDriverWait;

public class CheckFirstname
{
    public static WebDriver d;

    public static void main(String []args)throws Exception{
       System.setProperty("webdriver.firefox.marionette", "pathToGeckodriver");
       FirefoxDriver driver = new FirefoxDriver();

       driver.get("http://54.68.159.204/qmsadm");
       driver.manage().window().maximize();
       WebElement element = driver.findElement(By.name("username"));
       element.sendKeys("user name");
       element = driver.findElement(By.name("password"));
       element.sendKeys("password");
       element.submit();
       element = driver.findElement(By.linkText("Admin"));
       element.click();
       element = driver.findElement(By.linkText("Users"));
       element.click();
       element = driver.findElement(By.xpath("//*[@id='search-container']/a/i"));
       element.click();

       element = driver.findElement(By.id("username"));
       element.sendKeys("#!#!#$@#!$@!$@#$%#%^#$^^&%&$%*");

       driver.findElement(By.xpath("//*[@id='adduser']/div/form/div[2]/div/div/label")).click();
       Thread.sleep(1000);

       WebDriverWait wait = new WebDriverWait(driver, 0);

       wait.until(ExpectedConditions.alertIsPresent());

       Alert alert = driver.switchTo().alert();

       alert.accept();
   }

这是屏幕截图。在这里您可以检查一个警告框。我想弹出这个警告窗口。我试了几次，但还是不行。

做这样的事情:

在您尝试切换到警报之前，它需要存在。

driver.findElement(By.xpath("//*[@id='adduser']/div/form/div[2]/div/div/label")).click(); Thread.sleep(1000);
wait.until(ExpectedConditions.alertIsPresent());

Alert alert = driver.switchTo().alert();
alertText = alert.getText();
alert.accept();

以及为什么您会在这里收到警报 Alert alert=driver.switchTo().alert();如果您没有在下面的行中使用 String alertMessage=driver.switchTo().alert().getText(); ，你只是在写它是不必要的。希望能帮助到你。完整的java代码如下。

           element.sendKeys("geosony");
           element=driver.findElement(By.name("password"));
           element.sendKeys("1");
           element.submit();
           element=driver.findElement(By.linkText("Admin"));
           element.click();
           element=driver.findElement(By.linkText("Users"));
           element.click();
           element=driver.findElement(By.xpath("//*[@id='search-container']/a/i"));
           element.click();




           element= driver.findElement(By.id("username"));
           element.sendKeys("#!#!#$@#!$@!$@#$%#%^#$^^&%&$%*");

           driver.findElement(By.xpath("//*[@id='adduser']/div/form/div[2]/div/div/label")).click();
           Thread.sleep(1000);

        WebDriverWait wait = new WebDriverWait(driver, 30 );

            wait.until(ExpectedConditions.alertIsPresent());

        Alert alert = driver.switchTo().alert();

        alert.accept();
