如何选择表单元格，而无需在jQuery中选择嵌套表单元格

问题描述

我只想选择表中的'td'元素的第一级，而不是任何嵌套表的单元格。
例如：

I want to select only the first level of 'td' elements in a table and not the cells of any nested tables.eg:

<table id="Outer">
    <tr>

        <td> --this one
        </td>

        <td> --this one
            <table>
                <tr>
                    <td></td> -- but not this one or any deeper nested cells
                </tr>
            </table>
        </td>

    </tr>
</table>

（在生产代码中，是的，包括tbody，thead ...）

(and yes in prod code i would include tbody, thead...)

推荐答案

我会使用选择器，它只选择与表达式匹配的直接子项。为了方便选择外表，我给它一个名字。 注意：此选项不适用于您在adwords，tbody和tfoot的选择器中添加的示例，因为您表示您将在生产中。

I'd use the children selector, which only selects the immediate children matching the expression. To make it easy to select just the outer table, I'd give it a name. NOTE: this won't work with your sample as I've added in the selectors for thead, tbody, and tfoot as you indicate you will have in production. Adjust accordingly for your sample.

$('table#namedTable').children('tbody,thead,tfoot')
                     .children('tr')
                     .children('td')
