javascript - 获取表中的行数

Question

我想获取表中的行数。 我尝试了多种方法(没有任何成功)，最后我尝试了以下方法:

  var _tableOfInterestsCount = wait.Until(x => x.FindElements(By.XPath("//*[@id='gridBodyTable']/tbody")));
        var  _trs = wait.Until(x => x.FindElements(By.XPath(".//tr[@class = 'ms-crm-List-Row']")));

在调试时，当有 3 行时，我得到 Count = 1。一定。 所有 3 个 tr 都具有相同的类别。 此外，该表中甚至还有一个属性:numrecords="3" 当再次使用以下内容时，我得到的值是 1 而不是 3。

var _tableOfInterestsCount = wait.Until(x => x.FindElement(By.XPath("//*[@id='gridBodyTable']")).GetAttribute("numrecords"));

相关HTML代码:

		</tr></tbody>
	</table>

编辑: 顺便说一句，当有 2 行时，计数为 0。 我什至尝试了以下方法，但仍然得到错误的 adttribute 值:

 Dictionary<string, object> attributes = executor.ExecuteScript("var items = {}; for (index = 0; index < arguments[0].attributes.length; ++index) { items[arguments[0].attributes[index].name] = arguments[0].attributes[index].value }; return items;", _tableOfInterestsCount) as Dictionary<string, object>;

Answer 1

当表有 ID 时，为什么要通过 xpath 访问表？ 你通常应该这样做:

 var _tableOfInterestsCount =Driver.FindElement(By.Id("gridBodyTable"));
 List<IWebElement> _trs = _tableOfInterestsCount .FindElements(By.ClassName("ms-crm-List-Row")).ToList();
 int count=_trs.Count();

如果这不起作用，请同时共享 HTML 行。
