当我们处于较小的屏幕时,navbar-toggle
出现时,我们是否有相应的事件?
例如,
$('#myDropdown').on('shown.bs.navbar-toggle', function () {
// do something…
});
$('#myDropdown').on('hide.bs.navbar-toggle', function () {
// do something…
});
HTML,
<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="#">Home</a>-->
</div>
否则,我们如何检测在较小的屏幕上是否存在那个navbar-toggle
?
