我的导航栏是这样的:
我的HTML代码:
<div class="wrapper">
<div class="navbar navbar-default" role="navigation">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Project name</a>
</div>
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li class="active"><a href="#">Link</a></li>
<li><a href="#">Link</a></li>
<li><a href="#">Link</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li class="dropdown-header">Nav header</li>
<li><a href="#">Separated link</a></li>
<li><a href="#">One more separated link</a></li>
</ul>
</li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li class="active"><a href="./">Default</a></li>
<li><a href="../navbar-static-top/">Static top</a></li>
<li><a href="../navbar-fixed-top/">Fixed top</a></li>
</ul>
</div><!--/.nav-collapse -->
</div>
</div>
我的javascript代码:
$(document).ready(function () {
function CloseNav() {
$(".navbar-collapse").stop().css({ 'height': '1px' }).removeClass('in').addClass("collapse");
$(".navbar-toggle").stop().removeClass('collapsed');
}
$('html').click(function (event) {
var clickover = $(event.target);
var _opened = $(".navbar-collapse").hasClass("navbar-collapse in");
if (_opened === true && !clickover.hasClass("navbar-toggle")) {
CloseNav();
}
});
});
当在按钮外单击时,如何在我的菜单中关闭动画折叠。单击按钮外部时关闭但没有动画效果。如何在折叠打开时菜单按钮改变颜色?
答案 0 :(得分:0)
此解决方案可能适合您。将CloseNav()函数切换到下面:
function CloseNav() {
$(".navbar-collapse").stop().animate({'height': 0},300, function () {
$('.navbar-collapse').removeClass('in').addClass("collapse");
});
$(".navbar-toggle").stop().removeClass('collapsed');
};
看起来只需将.collapse
类添加到导航栏就可以立即切换高度。如果您制作动画然后添加该类,则会创建所需的上滑效果。
