这是脚本上的代码,我需要从第二个单元格中获取内容。 该表没有id,但是在id为'Chat'的div中
我可以选择第4行:
var row = $("#chat tr:nth-child(4)");
但不是第二个细胞:
var cellContent = $("#chat td:nth-child(4)").html();
我无法发布图片或表格标签,因此这是表格图像及其代码的链接。 http://img577.imageshack.us/img577/8871/chattable.png

这是一个小提琴,希望有助于你的jquery问题。 http://jsfiddle.net/CrumK/1/
$(document).ready(function() {
// this reads: find the element with ID chat and inside that find every TR element that is the 2nd child of its parent (meaning TABLE).
$("#chat tr:nth-child(2)").css("color", "blue"); // select the second row
// this reads: find the element with ID chat and inside that find every TD element that is the 2nd child of its parent (meaning TR)
$("#chat td:nth-child(2)").css("background", "red"); // select every second TD
// select the second TD of the second TR inside the #chat element
$("#chat tr:nth-child(2) td:nth-child(2)").css("background", "green"); // select the second row
});
