jQuery获取两个元素之间的同胞元素(适用于无限分类的显示隐藏)

<table class="table table-hover table-mail">    <tbody>    <tr class="unread">        <td >编号</td>        <td >分类名称</td>            <td class="text-center">操作</td>    </tr>        <tr class="read">            <td ></td>            <td ></td>            <td ></td>        </tr>        <tr class="child-read">           <td></td>           <td></td>        </tr>

<tr class="child-read">           <td></td>           <td></td>        </tr>

 <tr class="read">            <td ></td>            <td ></td>            <td ></td>        </tr>
    </tbody></table>

jQuery代码

//点击父tr时显示隐藏子tr$(function () {        $(this).click(function () {            var read = $(this).nextUntil(".read");            if (read.is(":hidden")) {                read.toggle(                    function () {                        read.show();                    }                )            } else {                read.toggle(                    function () {                        read.hide();                    }                )            }        });});
