我无法确定你的复选框在哪里或者它们的名字是什么,但我确实注意到你在脚本中使用了jQuery.我创建了一个快速的小jsFiddle演示,向您展示如何使用jQuery.在我的例子中,我创建了一个.highlight类,我将其设置为background-color我想要的颜色.在jQuery中,我将所有复选框分组并附加一个.change()处理程序,我在每次点击时打开/关闭高亮类.
HTML:
<div id="row-1"><input type="checkbox" id="chk-1" />Row 1</div>
<div id="row-2"><input type="checkbox" id="chk-2" />Row 2</div>
<div id="row-3"><input type="checkbox" id="chk-3" />Row 3</div>
<div id="row-4"><input type="checkbox" id="chk-4" />Row 4</div>
CSS:
div
{
display: block;
height: 20px;
padding: 20px;
border-bottom: dashed 1px #000;
}
input
{
margin-right: 10px;
}
.highlight
{
background-color: yellow;
}
jQuery的:
$("input[type=checkbox]").on("change", function() {
var $chk = $(this),
num = $chk.attr("id").substring(4),
$row = $("#row-" + num);
$row.toggleClass("highlight");
});
