I have a span defined, to which I am occasionally adding text and I am trying to get it to scroll to the bottom of the "box" but without success.
I have the span defined as:
<tr>
<td style="height:130px; border: 1px solid black;">
<div class="scrollable">
<span id="infoWindow"></span>
</div>
</td>
</tr>
With
div.scrollable
{
width: 100%;
height: 100%;
margin: 0;
padding: 0;
overflow: auto;
}
And I am adding to it as follows:
document.getElementById("infoWindow").innerHTML+="Just some blurb<hr>";
var objDiv = document.getElementById("infoWindow");
I have tried two different approaches:
objDiv.scrollTop = objDiv.scrollHeight - objDiv.clientHeight;
and
objDiv.scrollTop = objDiv.scrollHeight;
But neither work. What am I doing wrong? Many thanks!
scrollHeight and clientHeight are properties which are calculated when DOM has been fully painted. You should subscribe to event DOMContentLoaded to be sure the calculations are done.
There is a function scrollIntoView which you can use on any element which does exactly the name suggests. MDN - scrollIntoView. You can also define some options for scrolling like smoothness and position where to scroll exactly on element.
Here is an example I wrote to test this.
Keep in mind that scrollIntoView triggered by code example will impact SO scroll behavior.

I was creating a project in which i needed to show heading for a topic and when the mouse goes over it, it changes to information of that heading. I have managed to make it work however i don't want it to change instantly, i want to apply transition on it so it makes it more pleasing. The problem is i don't know which element to put it on. I tried to put it on all three but it didn't work. I would appreciate if someone helped me with it. Here's my code:
HTML
<div class="sop-container">
<div class="sop-body" onmouseover="showSop()" onmouseout="hideSop()">
<h1 id="sop-head">Lorem Ipsum</h1>
<p class="sop-p" id="sop-p">Lorem ipsum dolor sit amet consectetur adipisicing elit. Veritatis, tempore laudantium maiores eligendi tempora ab repellat nam possimus sit molestiae cumque officiis corporis optio officia commodi consequatur aperiam quaerat odit.</p>
</div>
<div class="sop-img">
<img src="masks.jpg" alt="">
</div>
</div>
CSS
.sop-body{
flex: 1;
background-color: #EAC435;
transition: 3s ease;
}
.sop-body h1{
text-align: center;
margin-top:125px;
transition: 3s ease-in-out;
}
.sop-body p{
display: none;
margin:5%;
letter-spacing: 1px;
font-size: large;
margin-top: 80px ;
transition: 3s ease-in-out;
}
.sop-img{
flex: 1;
overflow-y: hidden;
}
Javascript (just in case)
var sopBody = document.getElementById("sop-p");
var sopHead = document.getElementById("sop-head")
function showSop(){
sopBody.style.display = "block"
sopHead.style.display = "none"
}
function hideSop(){
sopBody.style.display = "none"
sopHead.style.display = "block"
}
transition doesn't work on the display property. Just think for a moment about how could you render a partial display element. You can't.
Alternatively, you can use opacity here
var sopBody = document.getElementById("sop-p");
var sopHead = document.getElementById("sop-head")
function showSop() {
sopBody.style.opacity = "1"
sopHead.style.opacity = "0"
}
function hideSop() {
sopBody.style.opacity = "0"
sopHead.style.opacity = "1"
}
.sop-body {
flex: 1;
background-color: #EAC435;
}
.sop-body h1 {
text-align: center;
margin-top: 125px;
transition: 1s ease-in-out;
}
.sop-body p {
opacity: 0;
margin: 5%;
letter-spacing: 1px;
font-size: large;
margin-top: 80px;
transition: 1s ease-in-out;
}
.sop-img {
flex: 1;
overflow-y: hidden;
}
<div class="sop-container">
<div class="sop-body" onmouseover="showSop()" onmouseout="hideSop()">
<h1 id="sop-head">Lorem Ipsum</h1>
<p class="sop-p" id="sop-p">Lorem ipsum dolor sit amet consectetur adipisicing elit. Veritatis, tempore laudantium maiores eligendi tempora ab repellat nam possimus sit molestiae cumque officiis corporis optio officia commodi consequatur aperiam quaerat odit.</p>

I'm converting jQuery plugins to Vanilla Javascript. I've adopted a Bootstrap-style plugin structure in my example. Once I've instantiated the Accordion object I save it to the dom element so I can later use various methods on the object. Is this an anti-pattern? I would really appreciate any suggestions on how to handle this if it's not correct.
const Accordion = function(element, options){
this.$element = element;
this.target = this.$element.getAttribute('href') || this.$element.dataset.target;
this.$target = document.getElementById(this.target);
this.$header = document.querySelector(`.accordion-header[data-target='${this.target}']`) || document.querySelector(`.accordion-header[href='${this.target}']`);
this.options = {...Accordion.defaults, ...options};
}
Accordion.defaults = {
closeOthers: false
}
Accordion.prototype.open = function(){
this.$header.classList.add('active');
this.$target.classList.add('active');
};
Accordion.prototype.close = function(){
this.$header.classList.remove('active');
this.$target.classList.remove('active');
};
Accordion.prototype.toggle = function(){
if(this.$target.classList.contains('active')){
this.close();
} else {
this.open();
}
};
function Plugin(options){
let accordion = this.Accordion;
if(!accordion){
accordion = new Accordion(this, options);
// Is it okay to store an object on the DOM element?
this.Accordion = accordion;
}
}
const $accordions = [...document.querySelectorAll('[data-toggle="accordion"]')];
const options = {
closeOthers: true
};
/* Call the plugin */
$accordions.forEach($acc => {
Plugin.call($acc, options);
});
$accordions.forEach($acc => {
$acc.addEventListener('click', e => {
e.target.Accordion.toggle();
e.preventDefault();
});
});
const $toggle1 = document.getElementById('toggle1');
const $toggle2 = document.getElementById('toggle2');
const $acc1 = document.getElementById('acc1');
const $acc2 = document.getElementById('acc2');
$toggle1.addEventListener('click', e =>{
$acc1.Accordion.toggle();
});
$toggle2.addEventListener('click', e =>{
$acc2.Accordion.toggle();
});
body {

padding: 10px;
}
.accordion {

}

I wouldn’t worry about it. The only potential problem is name collisions (some other code also tries to assign to element.Accordion and overwrites it). You could also do it with a Map.
var accordions = new Map()
function Accordion ( element ) {
accordions.set( element, this )
}
Accordion.get = element => accordions.get( element )
...
var accordion = Accordion.get( element )
So, this is a site that i'm currently working on and everything is fine except this:
As i got warned by one of the guys reviewing my current code, my menu/navigation disappears after being open and closed in its media-querie state, and resized back to monitor-width.
Simplified - follow these steps to see the problem:
Open the code snippet (i would suggest CodePen since the result is shown properly in it) and briefly admire my design. Tthat's it, thank you for your help. Just kidding, next step: resize the browser to the mentioned size (width 480px or less) so that you see the hamburger menu icon on top right, open the menu clicking on the icon, close it, and than change the browser back to full screen size! Do you see the navigation bar on the left?!
What am i missing here? I suppose that it should be a few more lines of JavaScript for some after state (just started learning JS so i dont know), but please look into it and teach me about possible solution(s).
And yes i know, it shouldn't affect any of those mobile users that i'm targeting with my media-queries 'cause nobody will resize it like that and barely anyone will see this, BUT...first thing - i want to make it perfect, and second - if there is something i missed or did wrong i want to hear about it and learn how to fix it/make it right.
Here is the CodePen link: https://codepen.io/anon/pen/VxmMrJ
And here is the code snippet:
function myFunction() {
var x = document.getElementById("menu");

It would be better to do this with a CSS class that it only changed in your mobile media query.
https://codepen.io/anon/pen/KRmYVR
CSS
#media only screen and (max-width: 480px) {
.mobileshow {
display: block !important;
}
}
JS
function myFunction() {
var x = document.getElementById("menu");
if(x.classList.contains("mobileshow")) {
x.classList.remove("mobileshow");
}
else {
x.classList.add("mobileshow");
}
}
Those attributes of "element.style" can only be set a value rather than get their value(you can run "console.log(x.style.display)" to prove it). if you must to get styles of an element, try "getComputedStyle"
Usually, I would hide an element by add a class, and show it by remove that class
const el = document.querySelector('.some-element')
function hideElement() {
if (!el.classList.contains('hidden')) {
el.classList.add('hidden')
}
}
function showElement() {
if (el.classList.contains('hidden')) {
el.classList.remove('hidden')
}
}
.hidden {
display: none;
}
/* you can try this, if you don't want that element to really disappear
.hidden {
opacity: 0;
}
*/
<div class="some-element"></div>
PS: My English is poor, hope you could understand it :)
I have a list with the following markup:
<div class="container">
<div class="element">
<input type="checkbox" id="checkbox1" class="toggler">
<label for="checkbox1">Toggle +</label>
<div class="more-info">
<p>...</p>
</div>
</div>
<div class="element">
...
</div>
</div>
The purpuse is to use pure CSS to make the toggle function, so I use this to hide/show the <div class="more-info">...</div>:
.more-info {
max-height: 0;
opacity: 0;
overflow: hidden;
transition: all .3s ease;
}
.toggler:checked ~ .more-info {
max-height: 200px;
opacity: 0;
overflow: hidden;
}
Under the container, I have a button that will get (in this case it is static) element and append to the container. And this is where I have my problem, the label in the new element won't toggle the checkbox. If I make the checkbox visible and check it directly it works.
I have also made a codepen to illustrate my problem.
Thanks in advance :)
You have two issues in your code. Firstly there's a $a() which should be just $(). You're also setting the class of the appended checkbox to chekcbox instead of checkbox. Try this:
$(document).ready(function() {
var i = 1;
$('#more').click(function(e) {
e.preventDefault();
var element, checkbox, label, moreInfo, dummyText;
i++
dummyText = $('<p />').text('Similique dis egestas aptent exercitationem sequi urna, nonummy laudantium, cillum pulvinar sociis assumenda? Minus nostra atque minima duis expedita ab irure sequi lectus natoque? Nihil. Similique dis egestas aptent exercitationem sequi urna, nonummy laudantium, cillum pulvinar sociis assumenda? Minus nostra atque minima duis expedita ab irure sequi lectus natoque? Nihil.');
checkbox = $('<input />', {
id: 'checkbox' + i,
class: 'toggler',
type: 'checkbox'
});
label = $('<label />', {
for: 'checkbox' + i,
text: 'Toggle +'
});
moreInfo = $('<div />', {
class: 'more-info',
html: dummyText
});
element = $('<div />', {
class: 'element'
}).append(checkbox, label, moreInfo);
$('.container').append(element);
})
});

I even checked this w3schools website to build the same, but wasn't successful, as explanation is quite difficult.
Can anybody help me out with this?
What if you try this?
.btn-group-vertical {
display: inline-block;
position: absolute;
vertical-align: middle;
z-index: 1;
}
Making the menu positioned absolutely, then adding a z-index so it stays in front.
Its called an off-canvas navigation:
The CSS is:
/* Navigation Menu - Background */
.navigation {
/* critical sizing and position styles */
width: 100%;
height: 100%;
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: 0;
/* non-critical appearance styles */
list-style: none;
background: #111;
}
/* Navigation Menu - List items */
.nav-item {
/* non-critical appearance styles */
width: 200px;
border-top: 1px solid #111;
border-bottom: 1px solid #000;
}
.nav-item a {
/* non-critical appearance styles */

<h1>Pure CSS Off-Screen Menu</h1>
<h3>Finally, an off-screen menu that doesn't require a bunch of Javascript to work. </h3>
<p>This concept relies on the <code>:checked</code> pseudo-selector as well as the general sibling <code>~</code> selector, so it has decent browser support.</p>
<p><strong>Browsers supported:</strong> IE9+, Firefox 3.5+, Chrome any, Safari 3.2+, Opera 9.5+</p>
