我需要添加多個類以實現響應目的。我想添加navbar-fixed-top
,之後它會將col-xs-4
添加到包含addxs
的每個元素,同樣的反應也適用於removeClass。級聯方式的jquery addClass
我嘗試下面的代碼,但沒有運氣。
<div class="middle">
<nav class="navbar navbar-default">
<div class="container">
<div class="row">
<div class="col-md-3 col-sm-3 addxs logo">
<div class="navbar-header">
<a href="#" class="navbar-brand">
logo
</a>
<button type="button" class="navbar-toggle collapsed toggle-red toggle-me" data-toggle="collapse" data-target="#bs-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
</div>
<div class="col-md-6 col-sm-6 addxs">
something
</div>
<div class="col-md-3 col-sm-3 addxs">
something
</div>
</div><!-- /.row -->
</div><!-- /.container -->
</nav>
</div><!-- /.middle -->
的Jquery:
$(function(){
if($(window).width() <= 480){
$(window).scroll(function() {
if($(this).scrollTop() > 240) {
$('.middle nav.navbar-default').addClass('navbar-fixed-top').parent().next().find('.addxs').addClass('col-xs-4');
}else{
$('.middle nav.navbar-default').removeClass('navbar-fixed-top').parent().next().find('.addxs').removeClass('col-xs-4');
}
});
}
});
