如何在seleniumjava中处理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的webtable

Question

目前我正在经历一种情况。在表的正文中有三行。如果行与文本匹配，我必须对每行执行一些操作。为此，我得到了行的大小，并使用For循环和检查条件。当满足条件时，我必须执行一些操作，通过这些操作将行从网络表中删除，这符合我的预期。此外，我得到了org.openqa.selenium.StaleElementReferenceException：这里"totalOrders.get(i(.click(("当循环尝试在此处的下一行执行操作时

这是我代码的一部分：

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();

}
}
}

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.
