你好，有帮助的硒窗口和框架切换的家伙（或女孩），

    @SuppressWarnings("rawtypes")
    public static void main(String[] args) throws InterruptedException {

    WebDriver driver = new FirefoxDriver();

    driver.get("http://www.lampsplus.com/products/franklin-iron-works-hickory-point-15-inch-high-outdoor-light__09569.html");

    Set<String> windows = driver.getWindowHandles();
    System.out.println("size:" + windows.size());

    driver.findElement(By.xpath(".//*[@id='pdAddToCart']")).click();


    WebDriverWait wait = new WebDriverWait(driver, 180);
                    wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("#aCheckOut1")));


    System.out.println("now size is:" + windows.size());

    driver.findElement(By.xpath(".//*[@id='aCheckOut1']")).click();

    //cc form info - omitted for brevity

    driver.close();
    }


    } 

Answer 1

这可能对你有用。WebDriverWait现在等待iframe变得可见，切换到iframe，然后单击所需的元素。

WebDriverWait wait = new WebDriverWait(driver, 180);
                wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("div#add-to-cart>iframe")));

driver.switchTo().frame(driver.findElement(By.cssSelector("div#add-to-cart>iframe")));
driver.findElement(By.xpath(".//*[@id='aCheckOut1']")).click();

在iframe中完成后，请记住重新退出：

driver.switchTo().defaultContent();
