Question

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
});

Jquery在表中选择第二个单元格
