这是要选哪个元素呢，我在 Chrome 里 document.querySelector 也是 null 没有选中任何元素的。`nth-child` 是支持的\r\n\r\n1. 已截图回答您的此问题。选择的是td元素。document.querySelector 也是有选中td元素的。\r\n2. 此外，发现 程序的selector可能是匹配首项，而非匹配所有项。\r\n在某些情况下，程序的匹配结果与document.querySelector的结果一致。但实际上，如能与document.querySelectorAll的结果一致，会更好。 因document.querySelector只选择第一项元素，而实际上更好的方式是匹配所有项。匹配所有项在chrome中是使用document.querySelectorAll以验证结果"}}
