我试图用
jquery调整我的页脚大小.到目前为止,当我调整窗口大小时,它不会添加类.我实施得对吗?
/* My jQuery: */
$(document).ready(function() {
$(window).on('resize', function(){
var win = $(this);
if (win.width() > 600) {
$("#anc").addClass('social-lg');
$("#ico").addClass("icon-lg");
} else {
$("#anc").addClass('social-sm');
$("#ico").addClass("icon-sm");
}
});
});
/* My CSS: */
.social-lg div.col-md-12 > ul > li > a {
border: 2px solid #616161;
border-radius: 50%;
display: inline-block;
letter-spacing: normal;
text-align: center;
height: 4.25rem;
width: 4.25rem;
}
.icon-lg div.col-md-12 > ul > li > a > i {
padding-top: .5rem;
font-size: 2em;
}
.social-sm div.col-md-12 > ul > li > a {
border: 2px solid #616161;
border-radius: 50%;
display: inline-block;
letter-spacing: normal;
text-align: center;
height: 3.25rem;
width: 3.25rem;
}
.icon-sm div.col-md-12 > ul > li > a > i {
padding-top: .5rem;
font-size: 1.5em;
}
<!-- My HTML: -->
<div class="row" id="footer">
<div class="col-md-12">
<ul>
<li><a id="anc" class="nostyle" href="https://www.linkedin.com/in/"><i id="ico" class="fa fa-linkedin fa-2x" aria-hidden="true"></i></a></li>
<li><a id="anc" class="nostyle" href="https://github.com/"><i id="ico" class="fa fa-github fa-2x" aria-hidden="true"></i></a></li>
<li><a id="anc" class="nostyle" href="https://www.instagram.com/_/"><i id="ico" class="fa fa-instagram fa-2x" aria-hidden="true"></i></a></li>
<li><a id="anc" class="nostyle" href="https://twitter.com/"><i id="ico" class="fa fa-twitter fa-2x" aria-hidden="true"></i></a></li>
<p>Lorem Ipsum</p>
</ul>
</div>
</div>
编辑:问题中的嵌入代码而不是提供链接
最佳答案 对于li和i标记,你有许多相同的id参数,这会阻止jquery选择相同id的所有元素,所以让它们像下面这样的类
<div class="row" id="footer">
<div class="col-md-12">
<ul>
<li><a class="anc nostyle" href="https://www.linkedin.com/in/"><i class="ico fa fa-linkedin fa-2x" aria-hidden="true"></i></a></li>
<li><a class="anc nostyle" href="https://github.com/"><i class="ico fa fa-github fa-2x" aria-hidden="true"></i></a></li>
<li><a class="anc nostyle" href="https://www.instagram.com/_/"><i class="ico fa fa-instagram fa-2x" aria-hidden="true"></i></a></li>
<li><a class="anc nostyle" href="https://twitter.com/"><i class="ico fa fa-twitter fa-2x" aria-hidden="true"></i></a></li>
<p>Lorem Ipsum</p>
</ul>
</div>
</div>
然后使用修改后的javascript代码
$(document).ready(function() {
$(window).on('resize', function() {
var win = $(this);
if (win.width() > 600) {
$(".anc").addClass('social-lg').removeClass('social-sm');
$(".ico").addClass("icon-lg").removeClass("icon-sm");
} else {
$(".anc").addClass('social-sm').removeClass('social-lg');
$(".ico").addClass("icon-sm").removeClass("icon-lg");
}
}).trigger("resize"); //this to force first event on load
});
