java - 如何在分页式Web表格中找到所需的值？

Question

该页面具有分页的Web表格。我想查看表格并检查是否没有包含来自param的文本的单元格-单击下一步按钮，然后再次检查

我试图写类似的东西。我写了遍历行列表并从每行中指定列下的单元格获取文本的方法

protected GroupTableContainerComponent getContainerComponentByName(String groupCode) {
    GroupTableContainerComponent result = null;
    List<GroupTableContainerComponent> rows = getContainerComponents();
    Iterator<GroupTableContainerComponent> i = rows.iterator();
    while (i.hasNext()) {
        GroupTableContainerComponent current = i.next();

        if (!current.getGroupCodeText().toLowerCase().equals(groupCode.toLowerCase())) {
            clickNextButton();

            List<GroupTableContainerComponent> rows2 = getContainerComponents();
            Iterator<GroupTableContainerComponent> j = rows2.iterator();
            while (j.hasNext()){
                GroupTableContainerComponent current2 = j.next();
                if (current2.getGroupCodeText().toLowerCase().equals(groupCode.toLowerCase())){

                }
            }
        }
        result = current;
        break;
    }
    if (result == null) {
        throw new RuntimeException(String.format("Group with groupCode: %s not found", groupCode));
    }
    return result;
}

但是单击下一步按钮后，我得到错误StaleElementReferenceException

我认为这是因为我的行列表包含表上一页的旧行

这是我的getContainerComponent（）

public List<GroupTableContainerComponent> getContainerComponents() {
    containerComponents = new ArrayList<>();

    for (WebElement current : driver.findElements(By.xpath(groupTableContainerXpath))) {
        containerComponents.add(new GroupTableContainerComponent(current));
    }
    return containerComponents;
}

和Xpath

private final String groupTableContainerXpath = "//div[@class='table-container']/table/tbody/tr";

还有我的getGroupCodeText（）

public WebElement getGroupCode() {
    WebElement groupsCode = groupTableComponent.findElement(groupCode);
    return groupsCode;
}

public String getGroupCodeText() {
    return getGroupCode().getText();
}

和Xpath

private  By groupCode = By.xpath(".//td[contains(@class,'cdk-column-group_name')]");

我做到了，我决定在我的方法中创建列表。首先，我检查表格第一页中是否存在带参数的文本的单元格，如果该单元格不存在，我检查分页下一个按钮的状态，并在启用该功能时单击它，并等待第一个列表不可见，然后创建新列表并分配新值

protected GroupTableContainerComponent getContainerComponentByName(String groupCode) {
        GroupTableContainerComponent result = null;
        WebDriverWait waits = new WebDriverWait(driver, 10);
        List<WebElement> rows = driver.findElements(By.xpath(groupTableContainerXpath));
        List<GroupTableContainerComponent> containerComponents = new ArrayList<>();
        for (WebElement current : rows) {
            containerComponents.add(new GroupTableContainerComponent(current));
        }
        for (GroupTableContainerComponent current : containerComponents) {
            System.out.println(current.getGroupCodeText());
            if (current.getGroupCodeText().toLowerCase().equals(groupCode.toLowerCase())) {
                result = current;
                break;
            }

        }
        if (result == null){

            boolean isEnabled = isNextArrowEnabled();
            while (isEnabled) {
                clickNextButton();
                waits.until(ExpectedConditions.invisibilityOfAllElements(rows));
                List<WebElement> rows2 = waits.until(ExpectedConditions.visibilityOfAllElements(driver.findElements(By.xpath(groupTableContainerXpath))));
                List<GroupTableContainerComponent> containerComponents2 = new ArrayList<>();
                for (WebElement current2 : rows2) {
                    containerComponents2.add(new GroupTableContainerComponent(current2));

                }
                for (GroupTableContainerComponent current3 : containerComponents2) {
                    System.out.println(current3.getGroupCodeText());
                    if (current3.getGroupCodeText().toLowerCase().equals(groupCode.toLowerCase())) {
                        result = current3;
                        break;
                    }
                }

                if (result == null) {
                    if (isNextArrowEnabled()) isEnabled = true;
                    else isEnabled = false;
                } else return result;
            }
        }

            if (result == null) {
                throw new RuntimeException(String.format("Group with groupCode: %s not found", groupCode));
            }

        return result;
