How to implement dropdown menu Vanilla JS CSS [duplicate] - javascript

This question already has an answer here:
css3 transition dropdown onclick
(1 answer)
Closed 9 months ago.
I have been attempting to put together a drop down menu which slides down rather than "just appears" upon the click event. I tried to apply a transition to the drop down menu with no success. Help would be appreciated. I would like come to a solution with both css and javascript. Then menu should have a drop down effect when the button is clicked.

JS
document.querySelector("body").addEventListener("click", function(event){
let dropd = document.querySelector('#dropdown');
if (!event.target.parentNode.matches('#btn')) {
dropd.classList.remove("visible");
} else {
dropd.classList.toggle("visible");
}
});

You can't put a transition on the display property but you can set it on max-width. Change the dropdown style to this:
nav ul#dropdown {
list-style-type: none;
margin: 0;
padding-left: 0;
box-shadow: none;
overflow-y: hidden;
max-height: 0; /* approximate max height */
transition-property: all;
transition-duration: .5s
}
and change the .visibility style to this:
.visible {
max-height: 21vh !important; /* approximate max height */
}

While #Andrew Hulterstrom already solved the issue for you by using scaleY I wanted to show you some major chanegs in the JS code. I solve it with the same methode and code as Andrew just simpliefied the JS code to a single line. Instead of writing a long complicated code to implement an if/else-statment, I simply used the classList.toggle function:
function toggleDropdown() {
document.querySelector('nav').classList.toggle('hide');
};
body {
height: 100vh;
box-sizing: border-box;
margin: 0;
padding: 0;
}

Your code is very close to working. To achieve the slide effect you mentioned, you can use transform: scaleY() to make the dropdown expand:
.nav {
transform: scaleY(1);
transform-origin: top;
transition-property: transform;
transition-duration: .5s;
}
.hide {
transform: scaleY(0);
}
With that in place, all you have to do it properly toggle the hide class on the element that you want to expand. (thanks to #tacoshy for the suggestion to improve the js) Here's a full working example:
function toggleDropdown() {
document.querySelector('nav').classList.toggle('hide');
};
body {
height: 100vh;
box-sizing: border-box;
margin: 0;
padding: 0;
}
.logo {
display: block;
text-align: left;
background: #f8f9f9;
height: 10vh;
}
.logo #logo {
display: inline;
line-height: 10vh;
font-size: 1.6em;
margin-left: 0.5em;
color: #438ED9;
}
button#btn {
display: inline;
float: right;
margin-right: 2em;
margin-top: 0;
margin-bottom: 0;
border: none;
background-color: #f8f9f9;
padding: 0;
}

How do I use preventDefault to prevent checkbox from being clicked only when menu is open

I am trying to make it so that when the dropdown menu is open, the links of the menu are clickable and go to the url while at the same time the checkbox is disabled from being clicked. I want to use .preventdefault() to achieve this but not sure where to start. Some guidance here would be appreciated.
let btnn = document.getElementById("btn");
btnn.addEventListener('click', function(event) {
let dropdown = document.getElementById('dropdown');
dropdown.classList.toggle("visible");
})
document.body.addEventListener("click", (event) => {
let dropd = document.getElementById('dropdown');
dropd.classList.remove("visible");
event.preventDefault();
}, true)

Dropdown list appears (on hover) even when it's hidden inside the mobile menu

In my navbar I have a li item that opens a dropdown menu when someone hovers over it. In small screens I have a hamburger menu that hides it.
The problem is that in mobile view, even though the li item is "hidden" inside the menu when someone hovers over its position on screen it appears (even though it is hidden inside the menu).
I think that this probably happens because I set "visibility: hidden;" but I don't know how else to do it.
I mean I want to dropdown when someones hover it on desktop view but on mobile I want to dropdown only if someones open the menu and then hover over it (or maybe click on it).
To save space I included below only the code that I find more relevant.
$(function() {
$(".toggle").on("click", function() {
if ($(".item").hasClass("active")) {
$(".item").removeClass("active");
} else {
$(".item").addClass("active");
}
});

is there a way to change the menu text colour when at the top of a website

I am using a menu that has a background which is seethrough at the top and when you scroll down the background color of the menu changes to black. In one of my pages the background of the whole website is white so when the user scrolls to the top, the menu background is white which makes it impossible to read the menu text. I was wondering if there is a code that can change the color of the text of the menu when the menu bar is at the top of the website the menu text changes black so it is readable. here is a picture when the menu bar is at the top of the website
and not at the top. I'll add the code that codes for the menu bar.

You need to add the correct colors for .black class.
Before run the snippet click and Expand Snippet, because I added for large resolutions only, you can add in #media(max-width: 786px) for small resolutions (mobile devices).
I added <div style="height:1500px" class="only-for-scroll"></div> to force scroll.
I commented with //add this to you identify the changes that I did.

How to make responsive iframe google maps full screen

I am trying to embed google maps in the website using iframes. I need this map to be fullscreen on any device when the map is shown. I can't figure out a way to do this, tried setting width and height to 100% which made it look like this ):
But right now my website looks like this:
Any way of making the map fullscreen?

sorry i cant really get into adjusting your css right now but here is a little something i came up with when i need to output YouTube videos in iframes. try it out
<style>
#mediaPlayer{
position: relative;
height: auto;
padding-bottom: 56.25%;
padding-top: 1.875em;
overflow: hidden;
border: 0.1875em double #185875;
background-image:url('../video_loading.gif');
background-repeat: no-repeat;
background-size: cover;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-position: center;
background-attachment: fixed;
/*to adjust the height and width*/
margin-right: 20%;
margin-left: 20%;
margin-top: 20%;
margin-bottom: 20%;
/*or you can use it in single line*/
margin:20%;
/*or if you want different margins for different sides in a single line*/
margin: 20% 20% 20% 20%;
/* the above means margin: top right bottom left; */
}
#mediaPlayer iframe{
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
max-width: 100%;
max-height: 100%;
}
</style>
/*instead of using margin just add a div and specify the exact height and width you want*/
<div style="height: 50%; width:50%;">
<center>
<div id="mediaPlayer">
<iframe id="play_now" width="100%" height="100%" src="" value="" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
</div>
</center>
</div>
The video_loading.gif background is usually a good idea for users with slow network to have something in the background while your iframe content is loading
but you have to find your own unique gif file/image and set it's location in the background-image:url('../file-location-here.gif');
just replace your <div class="box"></div> with the code above let me know how it turns out.
How about the following example. The solution came from Responsive iframe (google maps) and weird resizing. By tweaking padding-top and padding-bottom you can change the size.
$(document).ready(function() {
$(".menu-icon").on("click", function() {
$("nav ul").toggleClass("showing");
});
});
// Scrolling Effect
$(window).on("scroll", function() {
if($(window).scrollTop()) {
$('nav').addClass('black');
}
else {
$('nav').removeClass('black');
}
})
.box {
position: relative;
padding-bottom: 56.25%;
padding-top: 25px;
height: 0;
overflow: hidden;
}
.box iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
border: none;
}

You can also try and use CSS variables:
$(document).ready(function() {
$(".menu-icon").on("click", function() {
$("nav ul").toggleClass("showing");
});
});
// Scrolling Effect
$(window).on("scroll", function() {
if($(window).scrollTop()) {
$('nav').addClass('black');
}
else {
$('nav').removeClass('black');
}
})
let events = ['load', 'resize'];
let googleMaps = document.querySelector('.box iframe');
events.forEach( event => {
window.addEventListener(event, () => {
googleMaps.style.setProperty('--google-maps-height', `${window.innerHeight}px`);
});
});

Are you looking for something like this? Add the following code to your css and see if it does the trick.
iframe {
height: 100vh;
width: 100vw;
box-sizing: border-box;
}
Take a look at using viewport percentage

Javascript dropdown menu not working

I'm trying to create dropdown menu that will open and collapse when the "mobile-nav" button gets clicked.
Please see this video or website as examples of the intended behavior:
https://www.youtube.com/watch?v=ozOSV75DgzU
http://travisneilson.com/
function mobileNav() {
$('.mobile-nav-toggle').on('click', function() {
var status = $(this).hasClass('is-open');
if (status) {
$('.mobile-nav-toggle, .mobile-nav').removeClass('is-open');
} else {
$('.mobile-nav-toggle, .mobile-nav').addClass('is-open');
}
});
}

You have to add link to jQuery script.
Delete declaration function mobileNav() { and it closing braket }.
$('.mobile-nav-toggle').on('click', function() {
var status = $(this).hasClass('is-open');
if (status) {
$('.mobile-nav-toggle, .mobile-nav').removeClass('is-open');
} else {
$('.mobile-nav-toggle, .mobile-nav').addClass('is-open');
}
});
Here is example of working code https://jsfiddle.net/efjz40ob/
