如何使用java在Lenium webdriver中切换到Jquery弹出窗口

我正面临一个jquery弹出窗口..我尝试使用以下代码来找出是否有弹出窗口，但输出显示没有弹出窗口。但我可以看到一个。。我无法切换到弹出窗口并执行操作。请任何人提出建议

public static boolean runScript(){
        JavascriptExecutor js = (JavascriptExecutor) driver;
        return  (Boolean) js.executeScript("return jQuery.active==0;");
        }


    public static void FocusOnWindow() throws Exception{
        int i=0;
        do {
            if(!runScript()){
                System.out.println("Popup exists");
                i++;
            }else{
                i=5000;
                System.out.println("Popup does not exists");
            }
        }while(i<5000);
    }

试试这个：

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

对于jqueryalert，它将起作用

public void testJQueryAlertHandling() {

        WebDriverWait jQueryWait = new WebDriverWait(driver, 2);
        try{
            jQueryWait.until(ExpectedConditions.presenceOfElementLocated(By.id("popup_container")));
             WebElement popup = driver.findElement(By.id("popup_container"));
             WebElement message = popup.findElement(By.id("popup_message"));
             assertEquals("Alert Message", message.getText());
             popup.findElement(By.id("popup_ok")).click();  
             System.out.println("Alert  Present");
        }
        catch (Exception e){
             System.out.println("No alert  Present");
        }        
     }

public void testJQueryAlertHandling() {

        WebDriverWait jQueryWait = new WebDriverWait(driver, 2);
        try{
            jQueryWait.until(ExpectedConditions.presenceOfElementLocated(By.id("popup_container")));
             WebElement popup = driver.findElement(By.id("popup_container"));
             WebElement message = popup.findElement(By.id("popup_message"));
             assertEquals("Alert Message", message.getText());
             popup.findElement(By.id("popup_ok")).click();  
             System.out.println("Alert  Present");
        }
        catch (Exception e){
             System.out.println("No alert  Present");
        }        
     }
