I want to do a hide/show menu that shows when you click the p
-tag with id menu
and hides when you click the same p
-tag — but apparently I'm useless on JavaScript. I don't want to use jQuery, I really want to learn this! Someone out there?
Here is my HTML:
<nav>
<p id="menu"> Menu</p>
<ul id="menu-box">
<li><a href="index.html">Start</a></li>
<li><a href="animal.html">Animal</a></li>
<li><a href="pictures.html">Pictures</a></li>
</ul>
</nav>
Here is my JavaScript (so far):
function setUp() {
document.getElementById("menu").onclick = setMenu;
}
function setMenu() {
var menuBox = document.getElementById("menu-box");
menuBox.className = "menuBox";
}
setUp();
function toggleMenu() { var menuBox = document.getElementById('menu-box'); if(menuBox.style.display == "block") { // if is menuBox displayed, hide it menuBox.style.display = "none"; } else { // if is menuBox hidden, display it menuBox.style.display = "block"; } }
<p id="menu" onclick="toggleMenu()"> Menu</p> <ul id="menu-box" style="display: block"> <li><a href="index.html">Start</a></li> <li><a href="animal.html">Animal</a></li> <li><a href="pictures.html">Pictures</a></li> </ul>
If your learning this drop down ,then i suggest you to learn it from this button :)
<div class="dropdown">
<button onclick="myFunction()" class="dropbtn">Dropdown</button>
<div id="myDropdown" class="dropdown-content">
<a href="#">Link 1</a>
<a href="#">Link 2</a>
<a href="#">Link 3</a>
</div>
</div>
and add this style
/* Dropdown Button */
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
}
/* Dropdown button on hover & focus */
.dropbtn:hover, .dropbtn:focus {
background-color: #3e8e41;
}
/* The container <div> - needed to position the dropdown content */
.dropdown {
position: relative;
display: inline-block;
}
/* Dropdown Content (Hidden by Default) */
.dropdown-content {
display: none;
position: absolute;
background-color: #f9f9f9;
min-width: 160px;
box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}
/* Links inside the dropdown */
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: block;
}
/* Change color of dropdown links on hover */
.dropdown-content a:hover {background-color: #f1f1f1}
/* Show the dropdown menu (use JS to add this class to the .dropdown-content container when the user clicks on the dropdown button) */
.show {display:block;}
Now toggle the hide and show with javascript
When the user clicks on the button, toggle between hiding and showing the dropdown content
function myFunction() {
document.getElementById("myDropdown").classList.toggle("show");
}
// Close the dropdown menu if the user clicks outside of it
window.onclick = function(event) {
if (!event.target.matches('.dropbtn')) {
var dropdowns = document.getElementsByClassName("dropdown-content");
var i;
for (i = 0; i < dropdowns.length; i++) {
var openDropdown = dropdowns[i];
if (openDropdown.classList.contains('show')) {
openDropdown.classList.remove('show');
}
}
}
}
Use this:
window.nav = { status: false, menu: function(){ if (nav.status){ // here put class when menu is open - eg: document.getElementById("menu-box").className = "menu-box menuopen"; nav.status = false; } else { // here put class when menu is closed - eg: document.getElementById("menu-box").className = "menu-box"; nav.status = true; } } }
.menu-box{ display: none; } .menuopen{ display: block; }
<nav> <p id="menu" onclick="nav.menu()"> Menu</p> <ul id="menu-box"> <li><a href="index.html">Start</a></li> <li><a href="animal.html">Animal</a></li> <li><a href="pictures.html">Pictures</a></li> </ul> </nav>
