我已经苦苦挣扎了几个小时,试图弄清楚如何在选择另一个“li”之前保留“li”元素的突出显示颜色。

我确实在 stackoverflow 上阅读了几个答案,但似乎没有一个对我有用。

我可以请求帮助吗?我确实尝试添加和删除类来设置属性和 jquery 设置属性的方式。但是,无法得到我想要的。

我愿意使用 CSS 或 JQUERY 来做到这一点。

我的CSS是

#cssmenu,
#cssmenu ul,
#cssmenu ul li,
#cssmenu ul li a {
margin: 0;
padding: 0;
border: 0;
list-style: none;
line-height: 2;
display: block;
position: relative;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}

#cssmenu {
width: auto;
margin-top: 68px;
margin-left: 6px;
margin-right: 6px;
border-top: double;
border-left: double;
border-right: double;
border-bottom: none;
border-color: brown;
}

#cssmenu.align-right ul li {
float: right;
border-right: 0;
border-left: 1px solid rgba(0, 0, 0, 0.22);
}

#cssmenu.align-right ul li a {
border-right: 0;
border-left: 1px solid rgba(255, 255, 255, 0.15);
}

#cssmenu ul {
background: #222222;
/* Old browsers */

background: -moz-linear-gradient(bottom, #000000 0%, #222222 50%, #3c3c3c 51%, #393939 78%, #888888 100%);

}

#cssmenu:after,
#cssmenu ul:after {

#cssmenu ul li {

#cssmenu ul li:hover,
#cssmenu ul li.active {

/* Old browsers */

background: -moz-linear-gradient(bottom, #0b4669 0%, #1275ae 50%, #1794dc 51%, #1691d8 78%, #98d2f4 100%);

}

#cssmenu ul li:hover::after,
#cssmenu ul li.active::after {

}

HTML代码是

<!doctype html>
<html lang=''>
<head>
<meta charset='utf-8'>
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

<script type="text/javascript">
$(document).ready(function(){
$("#page1").click(function(){
// $(this).css("background-color","black");
$('#rbl').load('main.php #tbl1');
if ($(this).hasClass('active')) {
$(this).removeClass('active')
}
else {
$(this).addClass('active')
}
});

$("#page2").click(function(){
setDivProps();
$('#rbl').load('main.php #tbl2');
});

$("#page3").click(function(){
setDivProps();
$('#rbl').load('main.php #tbl3');
});
});
</script>
</head>
<body>
<div>
<div id='cssmenu'>
<ul>
<li class='active'><a id="home1" href='#' ><span>HOME</span></a></li>
<li><a id="page1" href="#"><span>OPTION1</span></a></li>
<li><a id="page2" href="#"><span>OPTION2</span></a></li>
<li><a id="page3" href="#"><span>OPTION3</span></a></li>
</ul>
</div>
</div>
<div id="rbl"> </div>
</body>
<html>

最佳答案

使用这个 jquery 代码:

 $(document).ready(function(){
$('#cssmenu li').click(function(){
$("#cssmenu li").removeClass("active");
$(this).addClass("active");
});
});
