我正在尝试通过更改多个 div 来获取选项卡菜单。像那样: enter image description here
更改右侧的内容没问题我发现了很多结果。但是当我点击左侧的按钮时，如何切换标题和下面的下载内容……？ 我在互联网上搜索了几个小时来寻找此解决方案，但没有结果。
我从 w3schools 得到了垂直选项卡的这个:
function openCity(evt, cityName) {
var i, tabcontent, tablinks;
tabcontent = document.getElementsByClassName("tabcontent");
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
tablinks = document.getElementsByClassName("tablinks");
for (i = 0; i < tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(" active", "");
}
document.getElementById(cityName).style.display = "block";
evt.currentTarget.className += " active";
}
// Get the element with id="defaultOpen" and click on it
document.getElementById("defaultOpen").click(); * {box-sizing: border-box}
body {font-family: "Lato", sans-serif;}
/* Style the tab */
.tab {
float: left;
border: 1px solid #ccc;
background-color: #f1f1f1;
width: 30%;
height: 300px;
}
/* Style the buttons inside the tab */
.tab button {
display: block;
background-color: inherit;
color: black;
padding: 22px 16px;
width: 100%;
border: none;
outline: none;
text-align: left;
cursor: pointer;
transition: 0.3s;
font-size: 17px;
}
/* Change background color of buttons on hover */
.tab button:hover {
background-color: #ddd;
}
/* Create an active/current "tab button" class */
.tab button.active {
background-color: #ccc;
}
/* Style the tab content */
.tabcontent {
float: left;
padding: 0px 12px;
border: 1px solid #ccc;
width: 70%;
border-left: none;
height: 300px;

最佳答案
添加如下。
<div class="download downloadLondon">
var downloads = document.getElementsByClassName("download");
for (i = 0; i < tabcontent.length; i++) {
if (downloads[i].className.indexOf('download'+cityName) >= 0) {
downloads[i].style.display = "block";
}
else{
downloads[i].style.display = "none";
}
}
我认为如果你使用 jQuery 会更容易。
function openCity(evt, cityName) {
var i, tabcontent, tablinks;
tabcontent = document.getElementsByClassName("tabcontent");
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
tablinks = document.getElementsByClassName("tablinks");
for (i = 0; i < tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(" active", "");
}
document.getElementById(cityName).style.display = "block";
evt.currentTarget.className += " active";
var downloads = document.getElementsByClassName("download");
for (i = 0; i < downloads.length; i++) {
if (downloads[i].className.indexOf('download'+cityName) >= 0) {
downloads[i].style.display = "block";
}
else{
downloads[i].style.display = "none";
}
}
}
// Get the element with id="defaultOpen" and click on it
document.getElementById("defaultOpen").click(); * {box-sizing: border-box}
body {font-family: "Lato", sans-serif;}
/* Style the tab */
.tab {
float: left;
border: 1px solid #ccc;
background-color: #f1f1f1;
width: 30%;
height: 300px;
}
/* Style the buttons inside the tab */
.tab button {
display: block;
background-color: inherit;
color: black;
padding: 22px 16px;
width: 100%;
border: none;
outline: none;
text-align: left;
cursor: pointer;
transition: 0.3s;
font-size: 17px;
}
/* Change background color of buttons on hover */
.tab button:hover {
background-color: #ddd;
}
/* Create an active/current "tab button" class */
.tab button.active {
background-color: #ccc;
}
/* Style the tab content */
.tabcontent {
float: left;
padding: 0px 12px;
border: 1px solid #ccc;
width: 70%;
border-left: none;
height: 300px;
