如何用Java在Selenium中点击各菜单的子链接

Question

我正在尝试使用每个菜单的链接https://www.bloomingdales.com/Click子链接。下面是我尝试的代码。

public void iClickOnFOBSShouldVerifyTheRespectivePages() throws Throwable {

    List allElements = Elements.findElements(By.xpath("//ul[@id='mainNav']/li/a"));

    for (int i = 0; i <= allElements.size(); i++) {
        List<WebElement> links = Elements.findElements(By.xpath("//ul[@id='mainNav']/li/a"));
        WebElement ele = links.get(i);
        ele.click();


        List<WebElement> childlinks = Elements.findElements("left_facet.left_nav");
        for (int j = 0; j <= childlinks.size(); j++) {
            List<WebElement> ele2 = Elements.findElements(By.xpath("left_facet.left_nav"));
            WebElement ele3 = links.get(i);
            ele3.click();
            Navigate.browserBack();
        }
    }

下面是我得到的错误

org.openqa.selenium.staleElementReferenceException：过时元素引用：元素未附加到页面文档

尝试以下操作：：list ele=driver.findelements(By.xpath（“//ul[@id='main nav']/li/a”））；Actions act=新操作（驱动程序）；

    Thread.sleep(4000);

    for (int i = 0; i <= ele.size(); i++) {
        WebElement a =ele.get(i);
        act.moveToElement(a).build().perform();
        Thread.sleep(2000);
        List<WebElement>ChildMenu=driver.findElements(By.xpath("//nav[@id='nav']/div[2]/div/div/div[@class='flyoutCol']/div/ul/li"));
        System.out.println("Sub-Menu="+ChildMenu.size());
        for(int j=0;j<ChildMenu.size();j++){
            ChildMenu.get(i).click();
             Thread.sleep(2000);
             driver.navigate().back();
             Thread.sleep(2000);

            act.moveToElement(a).build().perform();
