当在行中执行某些操作时重新加载页面后表中的行数发生更改时，如何在 selenium java 中处理 webtable

如何解决当在行中执行某些操作时重新加载页面后表中的行数发生更改时，如何在 selenium java 中处理 webtable

目前我正在经历一个情况。表的主体中有三行。如果行与文本匹配，我必须对每一行执行一些操作。为此，我获取行的大小并使用 for 循环并检查条件。当条件满足时，我必须执行一些操作，根据我的期望，该行将从 webtable 中删除。此外，我收到 org.openqa.selenium.StaleElementReferenceException: here "totalOrders.get(i).click();"当循环尝试在下一行执行操作时

这是我的代码的一部分：

By loading = By.xpath("//div[@class='loading-wrap']");
By orders = By.xpath("//tbody/tr"); //this retruns 3 row

public void invoiceAllStockOrder() {

    eu.waitForInvisibilityOfElementLocated(loading,10);

    List<WebElement> totalOrders = eu.getElements(orders);
    int rowSize =totalOrders.size();
    if(rowSize == 0) {
        System.out.println("No order");
    }

    else {

        for (int i = 0; i < totalOrders.size(); i++) {
            eu.waitForInvisibilityOfElementLocated(loading,10);

            totalOrders.get(i).click();//getting stale element exception here when i = 1 but there are still 2 rows left
            selectInstockOrders();
            invoiceOrder();
                
        }
    }
}

解决方法

If the page has Javascript which automatically updates the DOM,you should assume a StaleElementException will occur.

Can you try with the below code,I hope this will work for you

public boolean retryingFindClick(By by) {
    boolean result = false;
    int attempts = 0;
    while(attempts < 2) {
        try {
            driver.findElement(by).click();
            result = true;
            break;
        } catch(StaleElementException e) {
        }
        attempts++;
    }
    return result;
}
This will attempt to find and click the element. If the DOM changes 
between the find and click,it will try again.
