我如何确保所有字段都加载到硒中的页面上，以便 none 过时？
How do I ensure that all fields are loaded on the page in selenium so that none are stale?
问题
我有一个 PeopleSoft 页面，我正在尝试使用 Java 的 Selenium Web 驱动程序对其进行测试。但是，我将 运行 保留为此错误：
org.openqa.selenium.StaleElementReferenceException: stale element reference: element is not attached to the page document
我已阅读 here, here, and here 以及其他 Stack Overflow 问题，none 的答案对我有用。
页面布局
我正在测试的 PeopleSoft 页面是一个 I9 表单，我关心的部分如下所示：
对应的 HTML 确实又大又乱——就像所有 PeopleSoft 页面一样——并且它在它的中间有一个 iframe 几乎包裹了 整个页。
供参考，此 JSFiddle 包含 iframe 中的所有 HTML。

运行 Selenium 代码
现在，我正在尝试将数据输入到此表单中，但我一直收到上述异常。当我来到这个页面时，我首先通过一个 SSO 页面来验证我的身份。然后它将我重定向到表单。那里没有问题。这是我执行此操作的代码（请注意，data 是一个包含数据的 POJO，而 driver 是一个 ChromeWebDriver）。
driver.switchTo().frame("TargetContent");
driver.findElement(By.id("G_FORM_I9_G_LAST_NAME")).clear();
driver.findElement(By.id("G_FORM_I9_G_LAST_NAME")).sendKeys(data.lastName, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_FIRST_NAME")).clear();
driver.findElement(By.id("G_FORM_I9_G_FIRST_NAME")).sendKeys(data.firstName, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_ADDRESS")).clear();
driver.findElement(By.id("G_FORM_I9_G_ADDRESS")).sendKeys(data.address, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_CITY")).clear();
driver.findElement(By.id("G_FORM_I9_G_CITY")).sendKeys(data.city, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_STATE")).clear();
driver.findElement(By.id("G_FORM_I9_G_STATE")).sendKeys(data.state, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_POSTAL")).clear();
driver.findElement(By.id("G_FORM_I9_G_POSTAL")).sendKeys(data.postal, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_EMAILID")).clear();
driver.findElement(By.id("G_FORM_I9_G_EMAILID")).sendKeys(data.email, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_CITIZEN_CHK")).click();
driver.findElement(By.id("G_FORM_I9_DRV_G_EE_SIGNATURE_PB")).click();
我在整个过程中的各个点都遇到了错误。有时它会在尝试将文本放入的第一个字段失败，有时会在第二个字段失败，有时会在后面的字段失败。
尝试的解决方案
为了解决这个问题，我试过调用这个方法：
private void waitForLoad(WebDriver driver)
{
new WebDriverWait(driver, 30)
.until((ExpectedCondition<Boolean>) wd -> ((JavascriptExecutor) wd)
.executeScript("return document.readyState").equals("complete"));
}
我也试过这个：
new WebDriverWait(driver, 5).until(ExpectedConditions.presenceOfAllElementsLocatedBy(By.xpath("//*[starts-with(@id, \"G_FORM_I9_\")]")));
我错过了什么？我还需要检查什么以确保这些字段实际上是可访问的？我曾多次尝试在 IntelliJ 中对此进行调试，但我怀疑在断点处停止的 act 会加载页面，所以我从未看到错误，因为没有元素是陈旧的。
看起来有时调用 clear() 会更改您的元素引用，并且在页面更新时，您正在尝试再次定位此元素并找到旧引用，这会导致 StaleElementReferenceException你sendKeys().
如果您已经知道遇到问题的字段，可以尝试以下操作：
WebDriverWait wait = new WebDriverWait (driver, 30);
WebElement element = driver.findElement(By.id("G_FORM_I9_G_LAST_NAME"));
element.clear();
wait.until(ExpectedConditions.stalenessOf(element));
driver.findElement(By.id("G_FORM_I9_G_LAST_NAME")).sendKeys(data.lastName, Keys.TAB);
但是如果您不知道是哪些字段导致了问题，并且该元素没有过时，您将得到 TimeoutException.

org.openqa.selenium.StaleElementReferenceException: stale element reference: element is not attached to the page document

运行 Selenium 代码
现在，我正在尝试将数据输入到此表单中，但我一直收到上述异常。当我来到这个页面时，我首先通过一个 SSO 页面来验证我的身份。然后它将我重定向到表单。那里没有问题。这是我执行此操作的代码（请注意，data 是一个包含数据的 POJO，而 driver 是一个 ChromeWebDriver）。
driver.switchTo().frame("TargetContent");
driver.findElement(By.id("G_FORM_I9_G_LAST_NAME")).clear();
driver.findElement(By.id("G_FORM_I9_G_LAST_NAME")).sendKeys(data.lastName, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_FIRST_NAME")).clear();
driver.findElement(By.id("G_FORM_I9_G_FIRST_NAME")).sendKeys(data.firstName, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_ADDRESS")).clear();
driver.findElement(By.id("G_FORM_I9_G_ADDRESS")).sendKeys(data.address, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_CITY")).clear();
driver.findElement(By.id("G_FORM_I9_G_CITY")).sendKeys(data.city, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_STATE")).clear();
driver.findElement(By.id("G_FORM_I9_G_STATE")).sendKeys(data.state, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_POSTAL")).clear();
driver.findElement(By.id("G_FORM_I9_G_POSTAL")).sendKeys(data.postal, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_EMAILID")).clear();
driver.findElement(By.id("G_FORM_I9_G_EMAILID")).sendKeys(data.email, Keys.TAB);
driver.findElement(By.id("G_FORM_I9_G_CITIZEN_CHK")).click();
driver.findElement(By.id("G_FORM_I9_DRV_G_EE_SIGNATURE_PB")).click();
我在整个过程中的各个点都遇到了错误。有时它会在尝试将文本放入的第一个字段失败，有时会在第二个字段失败，有时会在后面的字段失败。
尝试的解决方案
为了解决这个问题，我试过调用这个方法：
private void waitForLoad(WebDriver driver)
{
new WebDriverWait(driver, 30)
.until((ExpectedCondition<Boolean>) wd -> ((JavascriptExecutor) wd)
.executeScript("return document.readyState").equals("complete"));
}
我也试过这个：
new WebDriverWait(driver, 5).until(ExpectedConditions.presenceOfAllElementsLocatedBy(By.xpath("//*[starts-with(@id, \"G_FORM_I9_\")]")));
我错过了什么？我还需要检查什么以确保这些字段实际上是可访问的？我曾多次尝试在 IntelliJ 中对此进行调试，但我怀疑在断点处停止的 act 会加载页面，所以我从未看到错误，因为没有元素是陈旧的。
看起来有时调用 clear() 会更改您的元素引用，并且在页面更新时，您正在尝试再次定位此元素并找到旧引用，这会导致 StaleElementReferenceException你sendKeys().
如果您已经知道遇到问题的字段，可以尝试以下操作：
WebDriverWait wait = new WebDriverWait (driver, 30);
WebElement element = driver.findElement(By.id("G_FORM_I9_G_LAST_NAME"));
element.clear();
wait.until(ExpectedConditions.stalenessOf(element));
driver.findElement(By.id("G_FORM_I9_G_LAST_NAME")).sendKeys(data.lastName, Keys.TAB);
但是如果您不知道是哪些字段导致了问题，并且该元素没有过时，您将得到 TimeoutException.
