Selenium 错误 (Java) - 检测到框架，但在尝试切换到框架时提示 noSuchFrameException

Question

问题描述：

我无法通过 Chrome v92 切换到特定框架，尽管通过 Firefox 可以轻松切换。

代码示例：

@Test
    void auto_015_5() {
        int bet = 7;        
        driver.navigate().to("https://boademo.com/"); 
        driver.switchTo().frame(0);
        List < WebElement > counters = driver.findElements(By.xpath("//div[@class='counter']"));
        counters.get(0).click();     
        List < WebElement > marketOptions = driver.findElements(By.xpath("//div[@class='au-target market-option row nowrap can-place-bets']"));
        for (int i = 0; i <= (bet * 3) - 1; i += 3) {
            WebElement currentOption = marketOptions.get(i);
            JavascriptExecutor je = (JavascriptExecutor) driver;
            if (i % 6 == 0 && i >= 6) {
                je.executeScript("arguments[0].scrollIntoView(true);", marketOptions.get(i - 6));
            }
            currentOption.click();
        }
        
        driver.switchTo().defaultContent();
        driver.switchTo().frame(1);
    }

复制步骤：

导航到Link

切换到必要的框架(className = 'boa-iframe')

从'Matches' Lobby.中选择任何体育赛事

选择任意市场提示投注券(bottom-right).

切换到默认内容。

尝试切换到投注券的框架(className = 'boa-overlay-iframe')

NoSuchFrameException()

Answer 1

1. 您可以在显式等待的帮助下切换到iframe。
2. 索引不是首选。

示例代码：

driver.manage().window().maximize();
WebDriverWait wait = new WebDriverWait(driver, 30);
driver.manage().timeouts().implicitlyWait(300, TimeUnit.SECONDS);
driver.get("https://boademo.com/");
wait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("button.button-agree"))).click();
int bet = 7;        
wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.cssSelector("iframe.boa-iframe")));
List < WebElement > counters = driver.findElements(By.xpath("//div[@class='counter']"));
counters.get(0).click();     
List < WebElement > marketOptions = driver.findElements(By.xpath("//div[@class='au-target market-option row nowrap can-place-bets']"));
for (int i = 0; i <= (bet * 3) - 1; i += 3) {
    WebElement currentOption = marketOptions.get(i);
    JavascriptExecutor je = (JavascriptExecutor) driver;
       if (i % 6 == 0 && i >= 6) {
            je.executeScript("arguments[0].scrollIntoView(true);", marketOptions.get(i - 6));
        }
        currentOption.click();
    }
driver.switchTo().defaultContent();

wait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.cssSelector("iframe[class='boa-overlay-iframe']")));
System.out.println("You are inside boa-overlay-iframe");
