jquery - 动态更改数据表背景颜色
问题描述
无法使用 jquery 更改数据表的背景颜色。我试图在下面展示示例,但是当您运行它时,它并不能真正代表问题。当用户单击某些内容时,我需要将整个表格的背景更改为黑色。我想出了这一行,它改变了一些单元格而不是其他单元格。此外,当表格刷新数据时,单元格会变回。这两个原因都不是很好的解决方案。
jQuery('#tablepress-1_wrapper td:gt(0)').css('background-color', '#000000');
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="tablepress-1_wrapper" class="dataTables_wrapper no-footer" style="background-color: rgb(0, 0, 0);">
<div class="dataTables_length" id="tablepress-1_length"><label>Show <select name="tablepress-1_length" aria-controls="tablepress-1" class=""><option value="10">10</option><option value="25">25</option><option value="50">50</option><option value="100">100</option></select> entries</label></div>

class="dataTables_filter"><label>Search:<input class="" placeholder="" aria-controls="tablepress-1" type="search"></label></div>

解决方案
使用 CSS 管理样式。为背景颜色创建一个类(例如:.backBackground)并使用 jQuery 将其附加到表中,如下所示:
$('#tablepress-1').addClass('blackBackground');
您可以像这样轻松删除它:
$('#tablepress-1').removeClass('blackBackground');
你的 CSS 新类看起来像这样:
.blackBackground{
background-color: #000;
}
