use*_*222 3 html javascript css jquery
我需要在鼠标悬停时突出显示表格中单元格的行和列.生成的表格是动态的,我从数据库中获取值并显示在html表格中.表的结构完全如下所示,我无法修改现有结构.请使用我现有的html代码建议如何使用jquery/css突出显示表中选定的行和列.请找到小提琴http://jsfiddle.net/0w9yo8x6/78/.
以下是html代码:
<div>
<table border="1px">

<tr title="Table Header">

突出显示特定的行和列.对于我用作nth-child()选择器一部分的列.希望这可以帮助.
注意:我.myCell在第二级嵌套表的tds中添加了类,以便更轻松地使用jquery的选择器名称.
$(document).ready(function() {
$('.myCell').on('mouseover', function() {
$(this).closest('tr').addClass('highlight');
$(this).closest('table').find('.myCell:nth-child(' + ($(this).index() + 1) + ')').addClass('highlight');
});
$('.myCell').on('mouseout', function() {
$(this).closest('tr').removeClass('highlight');
$(this).closest('table').find('.myCell:nth-child(' + ($(this).index() + 1) + ')').removeClass('highlight');
});
});.highlight {
background-color:lightgray;

</div>由于您将表嵌套两层，因此您的 CSS 应该如下所示：
table table tr:hover td {
background-color: #fbc93d;
}
这是一个基于您的小提琴的示例：
