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( slides1.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();
}
}
}

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;
}

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');
var thumbsize = parseInt(slider.getAttribute('data-thumbsize'));
var rangewidth = parseInt(slider.getAttribute('data-rangewidth'));
var rangemin = parseInt(slider.getAttribute('data-rangemin'));
var rangemax = parseInt(slider.getAttribute('data-rangemax'));
/* set min and max attributes */
min.setAttribute('max',splitvalue);
max.setAttribute('min',splitvalue);
/* set css */
min.style.width = parseInt(thumbsize + ((splitvalue - rangemin)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
max.style.width = parseInt(thumbsize + ((rangemax - splitvalue)/(rangemax - rangemin))*(rangewidth - (2*thumbsize)))+'px';
min.style.left = '0px';
max.style.left = parseInt(min.style.width)+'px';
min.style.top = lower.offsetHeight+'px';
max.style.top = lower.offsetHeight+'px';
legend.style.marginTop = min.offsetHeight+'px';
slider.style.height = (lower.offsetHeight + min.offsetHeight + legend.offsetHeight)+'px';
/* correct for 1 off at the end */
if(max.value>(rangemax - 1)) max.setAttribute('data-value',rangemax);
/* write value and labels */
max.value = max.getAttribute('data-value');
min.value = min.getAttribute('data-value');
lower.innerHTML = min.getAttribute('data-value');
upper.innerHTML = max.getAttribute('data-value');
}
function init(slider) {
/* set function vars */
var min = slider.querySelector('.min');
var max = slider.querySelector('.max');
var rangemin = parseInt(min.getAttribute('min'));
var rangemax = parseInt(max.getAttribute('max'));
var avgvalue = (rangemin + rangemax)/2;
var legendnum = slider.getAttribute('data-legendnum');
/* set data-values */
min.setAttribute('data-value',rangemin);
max.setAttribute('data-value',rangemax);
/* set data vars */
slider.setAttribute('data-rangemin',rangemin);
slider.setAttribute('data-rangemax',rangemax);
slider.setAttribute('data-thumbsize',thumbsize);
slider.setAttribute('data-rangewidth',slider.offsetWidth);
/* write labels */
var lower = document.createElement('span');
var upper = document.createElement('span');
lower.classList.add('lower','value');
upper.classList.add('upper','value');
lower.appendChild(document.createTextNode(rangemin));
upper.appendChild(document.createTextNode(rangemax));
slider.insertBefore(lower,min.previousElementSibling);
slider.insertBefore(upper,min.previousElementSibling);
/* write legend */
var legend = document.createElement('div');
legend.classList.add('legend');
var legendvalues = [];
for (var i = 0; i < legendnum; i++) {
legendvalues[i] = document.createElement('div');
var val = Math.round(rangemin+(i/(legendnum-1))*(rangemax - rangemin));
legendvalues[i].appendChild(document.createTextNode(val));
legend.appendChild(legendvalues[i]);
}
slider.appendChild(legend);
/* draw */
draw(slider,avgvalue);
/* events */
min.addEventListener("input", function() {update(min);});
max.addEventListener("input", function() {update(max);});
}
function update(el){
/* set function vars */
var slider = el.parentElement;
var min = slider.querySelector('#min');
var max = slider.querySelector('#max');
var minvalue = Math.floor(min.value);
var maxvalue = Math.floor(max.value);
/* set inactive values before draw */
min.setAttribute('data-value',minvalue);
max.setAttribute('data-value',maxvalue);
var avgvalue = (minvalue + maxvalue)/2;
/* draw */
draw(slider,avgvalue);

<label for="max">Maximum price</label>
<input id="max" class="max" name="max" type="range" step="1" min="0" max="3000" />

Note that you should keep the step size to 1 to prevent the values to change due to redraws/redraw bugs.

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-changedevent (or whateverevent-name-to-emit-on-changeyou 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.

Here is a reusable double range slider implementation, base on tutorial Double Range Slider by Coding Artist
- near native UI, Chrome/Firefox/Safari compatible
- API EventTarget based, with change/input events, minGap/maxGap properties

<h3>Double Range Slider, Reusable Edition</h3>
<div class="slider-container">
<div class="slider-track"></div>
<input type="range" name="a" min="-130" max="-30" step="1" value="-100" autocomplete="off" />
<input type="range" name="a" min="-60" max="0" step="2" value="-30" autocomplete="off" />

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

Solution 9 - Forms
This code covers following points
-
Dual slider using HTML, CSS, JS
-
I have modified this slider using embedded ruby so we can save previously applied values using params in rails.
<% left_width = params[:min].nil? ? 0 : ((params[:min].to_f/100000) * 100).to_i %> <% left_value = params[:min].nil? ? '0' : params[:min] %> <% right_width = params[:max].nil? ? 100 : ((params[:max].to_f/100000) * 100).to_i %> <% right_value = params[:max].nil? ? '100000' : params[:max] %> <div class="range-slider-outer"> <div slider id="slider-distance"> <div class="slider-inner"> <div inverse-left style="width:<%= left_width %>%;"></div> <div inverse-right style="width:<%= 100 - right_width %>%;"></div> <div range style="left:<%= left_width %>%;right:<%= 100 - right_width %>%;"></div> <span thumb style="left:<%= left_width %>%;"></span> <span thumb style="left:<%= right_width %>%;"></span> <div sign style=""> Rs.<span id="value"><%= left_value.to_i %></span> to </div> <div sign style=""> Rs.<span id="value"><%= right_value.to_i %></span> </div> </div> <input type="range" name="min" value=<%= left_value %> max="100000" min="0" step="100" oninput=" this.value=Math.min(this.value,this.parentNode.childNodes[5].value-1); let value = (this.value/parseInt(this.max))*100 var children = this.parentNode.childNodes[1].childNodes; children[1].style.width=value+'%'; children[5].style.left=value+'%'; children[7].style.left=value+'%';children[11].style.left=value+'%'; children[11].childNodes[1].innerHTML=this.value;" /> <input type="range" name="max" value=<%= right_value %> max="100000" min="0" step="100" oninput=" this.value=Math.max(this.value,this.parentNode.childNodes[3].value-(-1)); let value = (this.value/parseInt(this.max))*100 var children = this.parentNode.childNodes[1].childNodes; children[3].style.width=(100-value)+'%'; children[5].style.right=(100-value)+'%'; children[9].style.left=value+'%';children[13].style.left=value+'%'; children[13].childNodes[1].innerHTML=this.value;" /> </div> <div class="range-label"> <div>0</div> <div>100000</div> </div> </div>
