Show / hide multiple sections of Javascript
Looking for some good JavaScript to help me hide / show multiple divs with a button without clicking the href so I can use it in blogger. I've been looking for an answer for a while and couldn't find a good one that uses JavaScript and / or CSS. I'm a bit of a beginner, so bear with me. Below is my code that works, but I would like to simplify it and make it work so that it closes the div when I click the corresponding button again.
CSS
<head>
<style>
#myDIV1 {
width: 150px;
height: 150px;
background-color: lightblue;
display: none;
}
#myDIV2 {
width: 150px;
height: 150px;
background-color: lightblue;
display: none;
}
#myDIV3 {
width: 150px;
height: 150px;
background-color: lightblue;
display: none;
}
#myDIV4 {
width: 150px;
height: 150px;
background-color: lightblue;
display: none;
}
</style>
</head>
I know there is an easier way, but this is the only way I can find that works for what I want it to do most of
Html
<body>
<p>Click button to see div.</p>
<button onclick="myFunction1()">One</button>
<button onclick="myFunction2()">Two</button>
<button onclick="myFunction3()">Three</button>
<button onclick="myFunction4()">Four</button>
<div id="myDIV1">
This is the div1 element.
</div>
<div id="myDIV2">
This is the div2 element.
</div>
<div id="myDIV3">
This is the div3 element.
</div>
<div id="myDIV4">
This is the div4 element.
</div>
Javascript
<script>
function myFunction1() {
document.getElementById("myDIV1").style.display = "block";
document.getElementById("myDIV2").style.display = "none";
document.getElementById("myDIV3").style.display = "none";
document.getElementById("myDIV4").style.display = "none";
}
function myFunction2() {
document.getElementById("myDIV1").style.display = "none";
document.getElementById("myDIV2").style.display = "block";
document.getElementById("myDIV3").style.display = "none";
document.getElementById("myDIV4").style.display = "none";
}
function myFunction3() {
document.getElementById("myDIV1").style.display = "none";
document.getElementById("myDIV2").style.display = "none";
document.getElementById("myDIV3").style.display = "block";
document.getElementById("myDIV4").style.display = "none";
}
function myFunction4() {
document.getElementById("myDIV1").style.display = "none";
document.getElementById("myDIV2").style.display = "none";
document.getElementById("myDIV3").style.display = "none";
document.getElementById("myDIV4").style.display = "block";
}
</script>
Any help would be appreciated in advance.

I would suggest separating your code first - it will be cleaner and reusable - eg myStyle.css , myScript.js , index.html
Add the file css
and js
to the file html
, for example -
<link rel="stylesheet" type="text/css" href="myStyle.css">
<script type="text/javascript" src="myScript.js"></script>
src
→ indicates the path to the original file file. Here I assume that all of our files css
, js
, 'the html' are the same.
var divs = ["Div1", "Div2", "Div3", "Div4"];
var visibleDivId = null;
function divVisibility(divId) {
if(visibleDivId === divId) {
visibleDivId = null;
} else {
visibleDivId = divId;
}
hideNonVisibleDivs();
}
function hideNonVisibleDivs() {
var i, divId, div;
for(i = 0; i < divs.length; i++) {
divId = divs[i];
div = document.getElementById(divId);
if(visibleDivId === divId) {
div.style.display = "block";
} else {
div.style.display = "none";
}
}
}
.buttons a {
font-size: 16px;
}
.buttons a:hover {
cursor:pointer;
font-size: 16px;
}
<div class="main_div">
<div class="buttons">
<a href="#" onclick="divVisibility('Div1');">Div1</a> |
<a href="#" onclick="divVisibility('Div2');">Div2</a> |
<a href="#" onclick="divVisibility('Div3');">Div3</a> |
<a href="#" onclick="divVisibility('Div4');">Div4</a>
</div>
<div class="inner_div">
<div id="Div1">I'm Div One</div>
<div id="Div2" style="display: none;">I'm Div Two</div>
<div id="Div3" style="display: none;">I'm Div Three</div>
<div id="Div4" style="display: none;">I'm Div Four</div>
</div>
</div>

if you want to hide / show all divs at the same time than you have to give all divs one class for ex: .toggle and you can do this:
function myFunction1(){
$(".toggle").slideToggle();
}
if you want to hide / show one div at a time than you can do it with id:
function myFunction1(){
$("#myDIV1").slideToggle();
}
with different buttons:
function myFunction1(id){
$("#"+id).slideToggle();
}
go here:
<button onclick="myFunction1('myDIV1')">One</button>
<button onclick="myFunction1('myDIV2')">Two</button>
<button onclick="myFunction1('myDIV3')">Three</button>
<button onclick="myFunction1('myDIV4')">Four</button>

I found an answer to what I wanted with the .toggle function, thanks for the help. The answer I found here: radomsnippets.com

We can easily add an unlimited number of buttons using reusable code.
here is a complete example! Enjoy

}
.button{
