我在 Wordpress 中使用 Bootstrap V3 。
我想要实现的是,当有人点击折叠的button
菜单中的navbar
时,带有div
类的.slider
会获得额外的等级。
这是导航栏中的 HTML :
<nav class="navbar navbar-default navbar-static-top">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar">
<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 class="collapse navbar-collapse" id="navbar">
<?php
wp_nav_menu( array(
'theme_location' => 'navbar-right',
'depth' => 2,
'menu_class' => 'nav navbar-nav navbar-right',
'fallback_cb' => 'wp_bootstrap_navwalker::fallback',
'walker' => new wp_bootstrap_navwalker())
);
?>
</div><!-- /.navbar-collapse -->
</div><!-- /.container -->
</nav>
这是我要添加额外课程的div
中的 HTML :
<div class="slider">
<div class="container">
<div class="row">
other elements
</div> <!-- close row -->
</div> <!-- close container -->
</div> <!-- close slider -->
我用 CSS :
尝试了这个.navbar-default .navbar-collapse .in ~ .slider{
margin-top: -246px;
padding-top: 176px;
}
这是 jQuery :
$(function() {
$("#navbar").click(function() {
$(".slider").addClass("sliderMove");
});
});
应添加在滑块上的额外类是:
.sliderMove{
margin-top: -246px;
padding-top: 176px;
}
这样做的目的是在navbar
之后/之下的滑块在navbar
处于折叠状态之后。

您愿意点击的按钮是一个班级navbar-toggle
,而拥有导航栏的div的ID为navbar
。因此,要在按钮上实现点击事件,您必须使用button
ID而不是div
ID。所以你的jQuery代码就像:
$('.navbar-toggle').click(function(){
if($('#navbar').hasClass('in')){
$(".slider").addClass("sliderMove");
}else{
$(".slider").removeClass("sliderMove");
}
});
当您使用相同的按钮再次折叠菜单时,您想删除该类。

您只需要挂钩可折叠导航栏的Bootstrap崩溃事件即可。无需为折叠导航按钮指定额外的点击处理程序。
Bootstrap的崩溃类暴露了一些事件以挂钩崩溃功能。
这是一个例子。
$('#bs-example-navbar-collapse-1').on('show.bs.collapse', function () {
$(".slider").addClass("your-class");
})
$('#bs-example-navbar-collapse-1').on('hide.bs.collapse', function () {
$(".slider").removeClass("your-class");
})
.slider {
width: 100%;
min-height: 100px;
background-color: tomato;
}
.your-class {
background-color: lawngreen;
}

尝试这样的事情: (正如您在用户单击导航栏切换按钮时所需,使用jQuery将某个类添加到某个div)
$('body').ready(function() {
$('.navbar-toggle').on('click', function() {
$(".slider").toggleClass("sliderMove");
});
});

你做得很好但是你需要使用toggleClass()
并选择其他不是#navbar
还可以添加延迟吗?因为在导航栏完全折叠之前已经激活了类。
是的,可以通过添加setTimeout()
$(".collapsed").click(function() {
// toggle the class after half second
setTimeout(function() {
$(".slider").toggleClass("sliderMove");
}, 500);
});
/* just to show in small devices */
@media (max-width: 992px) {
.sliderMove {
background: red;
height: 100vh;
width: 100%
}
}
