我的菜单有一个问题。
这是来自codepen.io的问题 DEMO
在此演示中,您可以看到左侧边栏菜单区域。当您更改浏览器尺寸width < 1050px
时,菜单opacity:0;
和按钮将显示在左上角(蓝色按钮)。
当我点击按钮时,问题是左侧边栏没有打开。此处的工作示例没有 css媒体屏幕。
在没有css媒体屏幕的情况下使用 DEMO
这是一段代码:
HTML
<div class="header-left">
Change browser size width < 1050px
<div class="menu-area">
<div class="icon-header-home-menu menu-show-hide">Click to Show Button now</div>
<div class="menu-area-wrap ">
<div class="menu-item-info">MENU AREA</div>
</div>
</div>
</div>
CSS
.header-left{
float: left;
width: 50%;
background-color:black;
color:#ffffff;
padding:10px;
}
.menu-area {
float: left;
}
.icon-header-home-menu {
margin: 0;
padding: 4px 0px 0px 0px;
margin-left: 5px;
width: 100%;
color: #ffffff;
overflow: hidden;
float: left;
font-size: 25px;
background-color:blue;
}
.menu-area-wrap {
position: absolute;
width: 230px;
height: 800px;
top: 42px;
left: 52px;
background-color:red;
}
.menu-item-info {

overflow: hidden;
padding-top: 20px;
background-color:green;
}
.menu-area-wrap.active {
opacity:1;
-webkit-transform-origin: right top 0px;
-webkit-transform: scale(1);
}
.menu-show-hide{
display:none;
}
@media all and (max-width: 1050px) {
.menu-show-hide {
display:block;
}
.menu-area-wrap{
position: absolute;
top: 42px;
left:0; /*changed here*/
width:100%; /*changed here*/
z-index: 1000;
font-size: 14px;
text-align: left;
background: #009688;
background-clip: padding-box;
-webkit-transition: all 0.2s ease;
display:none;
-webkit-transform-origin: left top 0px;
-webkit-transform: scale(0);
opacity:0;
}
}
JS
$('html').click(function() {
$('.menu-area-wrap').removeClass("active");
});
$(".icon-header-home-menu").click (function(e){
e.stopPropagation();
$('.menu-area-wrap').toggleClass("active");
});
$('.menu-area-wrap').click (function(e){
e.stopPropagation();
});
答案 0 :(得分:1)
在媒体屏幕中尝试 :
.menu-area-wrap.active {
display: block;
}
当您的有效课程没有display: none
时,您的媒体屏幕有display:block
。
因此,在桌面版中,您正在更改不透明度,但在移动设备中,您正在更改显示,因此,您的有效课程不会执行任何操作,因为它仍会display:none
覆盖您的opacity: 0
。
$('html').click(function() {
$('.menu-area-wrap').removeClass("active");
});
$(".tt").click(function(e) {
e.stopPropagation();
$('.menu-area-wrap').toggleClass("active");
});
$('.menu-area-wrap').click(function(e) {
e.stopPropagation();
});

删除了移动设备中的display: none
。
$('html').click(function() {
$('.menu-area-wrap').removeClass("active");

$('.menu-area-wrap').toggleClass("active");
});
$('.menu-area-wrap').click(function(e) {
