I have a bar graph created in JavaScript to display values using colors. I am having trouble resetting the bar graph. Basically what needs to happen is when the "reset" button is clicked, all bars clear values and reset to "0". Then the button needs to give the option to "Generate" and the previous values are shown again. Also, this is my first time using constant velocity to ease the bars up and down as the button is clicked to give it a little flair. Not sure what I am missing to have the data clear and be set to zero on the bottom line of the graph while using constant velocity to make it ease down and when button is clicked to restore the values to previous state. Any help is appreciated. Here is the code so far:
HTML
/*
* Some base values.
*/
var millisecondsPerFrame = 30;
/*
* Helper function for managing button event handlers.
*/
var setupButton = function(button, label, onclickHandler) {
button.value = label;
button.onclick = onclickHandler;
button.disabled = false;
};
var startConstantVelocityAnimation = function() {
// Grab the desired velocity.
var velocity = parseFloat(document.getElementById("chart").value);
// Grab the object to animate, and initialize if necessary.
var colors = document.getElementById("colors");
chart.style.bottom = chart.style.bottom || "0px";
// Start animating.
var intervalID = setInterval(function() {
var newBottom = parseInt(box.style.bottom) + velocity;
if ((newBottom < 0) || (newBottom > maxBottom)) {
velocity = -velocity;
} else {
chart.style.bottom = newBottom + "px";
}
}, millisecondsPerFrame);
// Toggle the start button to stop animation.
setupButton(document.getElementById("Reset"), "Reset", function() {
clearInterval(intervalID);
// Toggle the start button to stop animation.
setupButton(document.getElementById("Reset"),
"Generate", startConstantVelocityAnimation);
});
};
window.onload = function() {
// Set up the initial event handlers.
document.getElementById("Reset").onclick = startConstantVelocityAnimation;
};

Is it possible to make a HTML5 slider with two input values, for example to select a price range? If so, how can it be done?
I've been looking for a lightweight, dependency free dual slider for some time (it seemed crazy to import jQuery just for this) and there don't seem to be many out there. I ended up modifying #Wildhoney's code a bit and really like it.
function getVals(){
// Get slider values
var parent = this.parentNode;
var slides = parent.getElementsByTagName("input");
var slide1 = parseFloat( slides[0].value );
var slide2 = parseFloat( slides[1].value );
// Neither slider will clip the other, so make sure we determine which is larger
if( slide1 > slide2 ){ var tmp = slide2; slide2 = slide1; slide1 = tmp; }
var displayElement = parent.getElementsByClassName("rangeValues")[0];
displayElement.innerHTML = slide1 + " - " + slide2;
}
window.onload = function(){
// Initialize Sliders
var sliderSections = document.getElementsByClassName("range-slider");
for( var x = 0; x < sliderSections.length; x++ ){
var sliders = sliderSections[x].getElementsByTagName("input");
for( var y = 0; y < sliders.length; y++ ){
if( sliders[y].type ==="range" ){
sliders[y].oninput = getVals;
// Manually trigger event first time to display values
sliders[y].oninput();
}
}
}
}
section.range-slider {
position: relative;
width: 200px;
height: 35px;
text-align: center;
}
section.range-slider input {
pointer-events: none;
position: absolute;
overflow: hidden;
left: 0;
top: 15px;
width: 200px;
outline: none;
height: 18px;
margin: 0;
padding: 0;
}
section.range-slider input::-webkit-slider-thumb {
pointer-events: all;
position: relative;
z-index: 1;
outline: 0;
}
section.range-slider input::-moz-range-thumb {
pointer-events: all;
position: relative;
z-index: 10;
-moz-appearance: none;
width: 9px;
}
section.range-slider input::-moz-range-track {
position: relative;
z-index: -1;
background-color: rgba(0, 0, 0, 1);
border: 0;
}
section.range-slider input:last-of-type::-moz-range-track {
-moz-appearance: none;
background: none transparent;
border: 0;
}
section.range-slider input[type=range]::-moz-focus-outer {
border: 0;
}
<!-- This block can be reused as many times as needed -->
<section class="range-slider">
<span class="rangeValues"></span>
<input value="5" min="0" max="15" step="0.5" type="range">
<input value="10" min="0" max="15" step="0.5" type="range">
</section>
No, the HTML5 range input only accepts one input. I would recommend you to use something like the jQuery UI range slider for that task.
Coming late, but noUiSlider avoids having a jQuery-ui dependency, which the accepted answer does not. Its only "caveat" is IE support is for IE9 and newer, if legacy IE is a deal breaker for you.
It's also free, open source and can be used in commercial projects without restrictions.
Installation: Download noUiSlider, extract the CSS and JS file somewhere in your site file system, and then link to the CSS from head and to JS from body:
<!-- In <head> -->
<link href="nouislider.min.css" rel="stylesheet">
<!-- In <body> -->
<script src="nouislider.min.js"></script>
Example usage: Creates a slider which goes from 0 to 100, and starts set to 20-80.
HTML:
<div id="slider">
</div>
JS:
var slider = document.getElementById('slider');
noUiSlider.create(slider, {
start: [20, 80],
connect: true,
range: {
'min': 0,
'max': 100
}
});
Sure you can simply use two sliders overlaying each other and add a bit of javascript (actually not more than 5 lines) that the selectors are not exceeding the min/max values (like in #Garys) solution.
Attached you'll find a short snippet adapted from a current project including some CSS3 styling to show what you can do (webkit only). I also added some labels to display the selected values.
It uses JQuery but a vanillajs version is no magic though.
#Update: The code below was just a proof of concept. Due to many requests I've added a possible solution for Mozilla Firefox (without changing the original code). You may want to refractor the code below before using it.
(function() {
function addSeparator(nStr) {
nStr += '';
var x = nStr.split('.');
var x1 = x[0];
var x2 = x.length > 1 ? '.' + x[1] : '';
var rgx = /(\d+)(\d{3})/;
while (rgx.test(x1)) {
x1 = x1.replace(rgx, '$1' + '.' + '$2');
}
return x1 + x2;
}
function rangeInputChangeEventHandler(e){
var rangeGroup = $(this).attr('name'),
minBtn = $(this).parent().children('.min'),
maxBtn = $(this).parent().children('.max'),
range_min = $(this).parent().children('.range_min'),
range_max = $(this).parent().children('.range_max'),
minVal = parseInt($(minBtn).val()),
maxVal = parseInt($(maxBtn).val()),
origin = $(this).context.className;
if(origin === 'min' && minVal > maxVal-5){
$(minBtn).val(maxVal-5);
}
var minVal = parseInt($(minBtn).val());
$(range_min).html(addSeparator(minVal*1000) + ' €');
if(origin === 'max' && maxVal-5 < minVal){
$(maxBtn).val(5+ minVal);
}
var maxVal = parseInt($(maxBtn).val());
$(range_max).html(addSeparator(maxVal*1000) + ' €');
}
$('input[type="range"]').on( 'input', rangeInputChangeEventHandler);
})();

Actually I used my script in html directly. But in javascript when you add oninput event listener for this event it gives the data automatically.You just need to assign the value as per your requirement.

The question was: "Is it possible to make a HTML5 slider with two input values, for example to select a price range? If so, how can it be done?"
In 2020 it is possible to create a fully accessible, native, non-jquery HTML5 slider with two thumbs for price ranges. If found this posted after I already created this solution and I thought that it would be nice to share my implementation here.
This implementation has been tested on mobile Chrome and Firefox (Android) and Chrome and Firefox (Linux). I am not sure about other platforms, but it should be quite good. I would love to get your feedback and improve this solution.
This solution allows multiple instances on one page and it consists of just two inputs (each) with descriptive labels for screen readers. You can set the thumb size in the amount of grid labels. Also, you can use touch, keyboard and mouse to interact with the slider. The value is updated during adjustment, due to the 'on input' event listener.
My first approach was to overlay the sliders and clip them. However, that resulted in complex code with a lot of browser dependencies. Then I recreated the solution with two sliders that were 'inline'. This is the solution you will find below.
var thumbsize = 14;
function draw(slider,splitvalue) {
/* set function vars */
var min = slider.querySelector('.min');
var max = slider.querySelector('.max');
var lower = slider.querySelector('.lower');
var upper = slider.querySelector('.upper');
var legend = slider.querySelector('.legend');

2022 - Accessible solution - 30 second solution to implement
This solution builds off of this answer by #JoostS. Accessibility is something none of the answers have focused on and that is a problem, so I built off of the above answer by making it more accessible & extensible since it had some flaws.
Usage is very simple:
Use the CDN or host the script locally: https://cdn.jsdelivr.net/gh/maxshuty/accessible-web-components/dist/simpleRange.min.js
Add this element to your template or HTML: <range-selector min-range="0" max-range="1000" />
Hook into it by listening for the range-changed event (or whatever event-name-to-emit-on-change you pass in)
That's it. View the full demo here. You can easily customize it by simply applying attributes like inputs-for-labels to use inputs instead of labels, slider-color to adjust the color, and so much more!
Here is a fiddle:
window.addEventListener('range-changed', (e) => {console.log(`Range changed for: ${e.detail.sliderId}. Min/Max range values are available in this object too`)})
<script src="https://cdn.jsdelivr.net/gh/maxshuty/accessible-web-components#latest/dist/simpleRange.min.js"></script>
<div>
<range-selector
id="rangeSelector1"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
number-of-legend-items-to-show="6"
/>
</div>
<div>
<range-selector
id="rangeSelector1"
min-label="Minimum"
max-label="Maximum"
min-range="1"
max-range="500"
number-of-legend-items-to-show="3"
inputs-for-labels
/>
</div>
<div>
<range-selector
id="rangeSelector2"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
number-of-legend-items-to-show="3"
slider-color="#6b5b95"
/>
</div>
<div>
<range-selector
id="rangeSelector3"
min-label="Minimum"
max-label="Maximum"
min-range="1000"
max-range="2022"
hide-label
hide-legend
/>
</div>
I decided to address the issues of the linked answer like the labels using display: none (bad for a11y), no visual focus on the slider, etc., and improve the code by cleaning up event listeners and making it much more dynamic and extensible.
I created this tiny library with many options to customize colors, event names, easily hook into it, make the accessible labels i18n capable and much more. Here it is in a fiddle if you want to play around.
You can easily customize the number of legend items it shows, hide or show the labels and legend, and customize the colors of everything, including the focus color like this.
Example using several of the props:
<range-selector
min-label="i18n Minimum Range"
max-label="i18n Maximum Range"
min-range="5"
max-range="555"
number-of-legend-items-to-show="6"
event-name-to-emit-on-change="my-custom-range-changed-event"
slider-color="orange"
circle-color="#f7cac9"
circle-border-color="#083535"
circle-focus-border-color="#3ec400"
/>
Then in your script:
window.addEventListener('my-custom-range-changed-event', (e) => { const data = e.detail; });
Finally if you see that this is missing something that you need I made it very easy to customize this library.
Simply copy this file and at the top you can see cssHelpers and constants objects that contain most of the variables you would likely want to further customize.
Since I built this with a Native Web Component I have taken advantage of disconnectedCallback and other hooks to clean up event listeners and set things up.

Changes:
1. allow different min/max/step for two inputs
2. new property 'maxGap'
3. added events 'input'/'change'
4. dropped IE/OldEdge support

I have a navigation bar. In it, I have some anchors. One of the anchors has the text 'Guides'. I want a div to appear when I hover over the anchor, and I want it to remain on the screen as long as I am hovering over the anchor. I also want the the div to remain on the screen as long as I am hovering over the div itself. All of this is working fine. When I scroll down, I decrease the size of the navigation bar and change the top position of the div. After I do this, the eventListener that I have set up to keep the div on the screen as long as I am hovering over it stops working. Please note that the div still appears when I hover over the anchor, and it remains on the screen as long as I am hovering over it.
Here's the code. The div is the one with id="dropdown-guides":
// Show dropdown on hovering over 'guides' in navigation bar

Please note that since the top set in CSS for the div is originally 80px, if I remove the code for changing the top of the div, after scrolling down, I can't reach it if I am hovering over the anchor, before it disappears. That's why I was not able to tell whether the eventListener stopped working because I scrolled down, or because I changed the top of the div.
I figured out the problem. In my javascript, I was setting the height of each navAnchor to fit only the text of the anchor. That's why the dropdown disappeared before I could hover over it. So I increased the height to extend the anchors to reach the bottom of the navigation bar. (I increased the height from 23px to 39px)
I need to make a fixed bottom footer to my WordPress web, with some buttons including js with a popover. I've Pillar Theme and I only need to make this change. I need to put it into my footer.php. But when I try, nothing works. I do not know if this is the best way to do that. Here is the code that I do for the footer:

You can try Sticky footer with jQuery. Add this code in your js file.
var $ = jQuery.noConflict();
jQuery(document).ready(function($){
/* sticky footer function */
StickyFooter()
});
/* Script on resize */
jQuery(window).resize(function($) {
/* sticky footer function */
StickyFooter();
});
/* Script on load
----------------------------------*/
jQuery(window).load(function($) {
/* sticky footer function */
StickyFooter();
});
/* Sticky Footer Function */
function StickyFooter(){
var Stickyfooter = jQuery( 'footer' ).outerHeight()
jQuery('#wrapper').css('margin-bottom',-Stickyfooter) /* Here #wrapper is your main <div> of <body> */
jQuery('#wrapper').css('padding-bottom',Stickyfooter)
}
I am unable to get a variable to function properly as the translateX value within my object. I am wanting to make the dot scroll across the page each time the next button is clicked. My code is only able to move it back and forth for the first step.
I am new to the animation API, and I have already made this work with CSS transitions but I am trying to get a good handle on the API.

The way I have it set up, I expect for the translateX values to increment or decrement depending on the click event listeners which would make the circle slide across the page. What is actually happening is that only the first step works. it will not go past the first stop point. If I log moveDot in the console it gives me the values that I am expecting, but it will only start/stop at 0 and 190. the back button functions the same way. link to fiddle
It is animated from and to the same place every time. Move the definition of moveDot into the event listener:
// give a starting value for the transformation
var startVal = 0;
// definte the timing
var dotTiming = {
duration: 400,
fill: "forwards",
easing: 'ease-in',
}
// on click fire the animation
document.getElementById('next').addEventListener('click', function() {
if (startVal > 380){return;}
// define the keyframes
var moveDot = [{transform: `translateX(${startVal}px)`},
{transform: `translateX(${startVal + 190}px)`}];
// make the animation happen
var movingDot = document.getElementById("progress__dot").animate(
moveDot,
dotTiming
);
movingDot.playbackRate = 1;
movingDot.play();
startVal += 190;
});
document.getElementById('back').addEventListener('click', function() {
movingDot.playbackRate = -1;
if (startVal >= 0) {
movingDot.play();
startVal -= 190;
}
});
I made a "To-List" with two icons that animate on the side. the icon on the right is not in the table. So when animating you can see it moving beyond the table. I can't understand why? any help please?
Thank you!
Hi, here is the fiddle:
https://jsfiddle.net/rggo2tmv/
As you can see, the garbage-bin icon disappears inside the table while the other icon (on the right) continues outside the table.

The icon inside the span element that you animate, doesn't "shrink" with the span as you might expect. It is shown to the right of the 0 width span instead (i.e. it overflows). You have the same effect both on the left and right side which is visible if you change the color of the icons.
Span is an inline element so it normally doesn't have the overflow property but you can use display: inline-block to display it with a given width and height. Use overflow: hidden to hide the icon when squeezing the width of the span element.
