我得到以下错误：
陈旧元素引用：元素未附加到页面文档。 当我从国家/地区下拉列表中选择一个国家/地区时，页面会刷新，因为我们使用了'onchange'属性，因此当我尝试在表单中找到其余字段时，它会向我抛出所声明的异常。
注意：我在页面加载之前和之后交叉验证了定位器， 它没有变化，因为大多数定位器都是id。
这是我的HTML，

我尝试了以下解决方案，
new WebDriverWait(driver, 500)
.ignoring(StaleElementReferenceException.class)
.until(new Predicate<WebDriver>() {
public boolean apply(@Nullable WebDriver driver) {
Select selectLanguage;
try {
selectLanguage = new Select(getWebElement("apj.newdoa.language"));
selectLanguage.selectByValue("EN");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return true;
}
});
第二个解决方案，
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)
.withTimeout( 120, TimeUnit.SECONDS )
.pollingEvery( 20, TimeUnit.SECONDS )
.ignoring( NoSuchElementException.class, StaleElementReferenceException.class );
// using a customized expected condition
Select foo1 = wait.until(new Function<WebDriver, Select>() {
Select selectLanguage;
public Select apply(WebDriver driver) {
try {
selectLanguage = new Select(getWebElement("apj.newdoa.language"));
logger.info("Value of Option:\t" +selectLanguage.toString());
return selectLanguage = new Select(getWebElement("apj.newdoa.language"));
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return selectLanguage;
}
});
foo1.selectByValue("EN");
