我有一个带有侧面导航栏的网站，它应该从右侧滑入，然后当您关闭它时，它会转换回侧面。在设计这个时，我意识到在单击侧边栏后，它会覆盖我的“transition:0.5s”样式，而只是出现。
这是我的代码
window.onclick = function(event){if(event.target == document.getElementById('outerNav')){closeNav();}};
function openNav() {
document.getElementById("outerNav").style.display = "block";
document.getElementById("outerNav").style.transition = "0.5s";
document.getElementById("jrc-sidenav").style.width = "250px";
document.getElementById("et-main-area").style.opacity = "0.7";
document.getElementById("jrc-sidenav-background").style.backgroundColor = "rgba(255,255,255,0.7)";
document.getElementById("hamburger").style.display = "none";
}
function closeNav() {
document.getElementById("jrc-sidenav").style.width = "0";
document.getElementById("et-main-area").style.opacity = "1";
document.getElementById("jrc-sidenav-background").style.backgroundColor = "#fff";
document.getElementById("hamburger").style.display = "block";
setTimeout(function(){
document.getElementById("outerNav").style.display = "none";
},500);
}
.outerNav {
display: none;
position: fixed;
left: 0;
top: 0;
width: 100%;
height: 100%;
overflow: hidden;
background-color: transparent;
transition: 0.5s;
}

最佳答案
问题是你的外部导航。当您打开菜单时，它被设置为“display:block”——没有转换。 如果您还通过过渡将其大小从 0% 调整为 100%，它应该可以工作。查看代码片段:
window.onclick = function(event) {
if (event.target == document.getElementById('outerNav')) {
closeNav();
}
};
function openNav() {
document.getElementById("outerNav").style.position = "fixed";
document.getElementById("outerNav").style.width = "100%"; //added this for opening the menu
document.getElementById("mySidenav").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";
document.body.style.backgroundColor = "rgba(0,0,0,0.4)";
}
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
document.getElementById("main").style.marginLeft = "0";
document.getElementById("outerNav").style.width = "0%";
document.body.style.backgroundColor = "white";
}body {
font-family: "Lato", sans-serif;
transition: background-color .5s;
}
.sidenav {
height: 100%;
width: 0;
position: fixed;
z-index: 1;
top: 0;
left: 0;
background-color: #111;
overflow-x: hidden;
transition: 0.5s;
padding-top: 60px;
}
.sidenav a {
padding: 8px 8px 8px 32px;
text-decoration: none;
font-size: 25px;
color: #818181;
display: block;
transition: 0.3s;
}
.sidenav a:hover {

}
.sidenav .closebtn {
position: absolute;
top: 0;
right: 25px;
font-size: 36px;
margin-left: 50px;
}
#main {
transition: margin-left .5s;
padding: 16px;
}
@media screen and (max-height: 450px) {
.sidenav {
padding-top: 15px;
}
.sidenav a {
font-size: 18px;
}
}
.outerNav {
display: block;
position: fixed;
left: 0;
top: 0;
width: 0%;
/* 0% when Menu is closed */
height: 100%;
overflow: hidden;
background-color: transparent;
transition: .5s;
