它总是returns行大小=0，虽然有超过10行 table 但是我无法获得行大小，因此我无法执行我的测试。我已经通过 xpath、css 选择器和 tagname 但 returns 当我打印 row.size();

时，行中没有任何结果

请帮我解决这个问题。

Answer 1

问题是因为 table 是动态加载的，所以他不得不等到整个 table 可用。 Thread.sleep(2000) 解决了这个问题，但不是很好的解决方案。我建议使用 WebDriverWait 和 .until() 方法，它们将在加载元素时获取元素。

List<WebElement>trList = wait.until(ExpectedConditions.visibilityOfNestedElementsLocatedBy(tbody, By.tagName("tr")));

当我尝试通过 selenium 中的 WebTable 时，总是给我 0 的行数
