Is there a way to make an HTML5 slider (input range) tag reset its position across page reloads? As is, it stays in its last dragged-to position when you reload the page.
Use autocomplete="off"
for example:
<input type="range" min="1" max="10" step="1" autocomplete="off" />
There is something else thats make your Range Input to maintain value across postback(reloads).
Because every time the form is reloaded the Range Input will be reseted.
Try
<html>
<head></head>
<body>
<form id="qweq">
<input type="range" min="1" max="10" step=""1 />
<input type="submit" text="reload"/>
</form>
</body>
</html>
just runs these in your browser ,you will see on submit click the page reloads and Input Range
is reseted

here is the input element:
<body class="container-fluid">
<input type="number" id="quantity" name="quantity" value="20" min="1" max="10000000">
</body>
When I change the value in the input, then reload, the changed value stays there and is not set back to the default.
How to I get it to always show the default value on loading?
how can I achieve that the parameters from the input elements range, are only submitted via GET-Request if the user interacts with the range slider before submitting. So that when the form is submitted the default values are not always submitted?
<div data-role="rangeslider">
<label for="range-1a">Rangeslider:</label>
<input type="range" name="absMin" id="rangeMin" min="0" max="1" value="0" step="0.1">
<label for="range-1b">Rangeslider:</label>
<input type="range" name="absMax" id="rangeMax" min="0" max="1" value="1" step="0.1">
</div>
Thanks a lot in advance
there're many ways to do that, maybe the easiest way is changing your slider's initial value to -1, but why you do that? what if your user actually want to choose but they don't do the slide because they feel like the slider already showed the value they wanted?
import React from 'react';
import { render } from 'react-dom';
const App = () => (
<input
type="number"
min={0}
max={99999}
step={1}
/>
);
render(<App />, document.getElementById('root'));
If i focus the input box and enter a number, I'm able to change the number by using the mouse scroll wheel while hovered over the input box.
However, when I create a .html file with the following content, I'm not able to change the number via scrolling. Any idea what's the reason?
<!DOCTYPE html>
<html>
<body>
<input
type="number"
min={0}
max={99999}
step={1}
/>
</body>
</html>
Looks like the scrolling behavior depends on whether there is an onWheel handler or not. When rendering two inputs on a page there is a difference:
<input id="input1" type="number" min="0" max="99999" step="1">
<input id="input2" type="number" min="0" max="99999" step="1" onwheel="">
Here input2 increments/decrements its value on mouse wheel, but input1 doesn't.
Since React attaches its own event handlers to dom elements, inputs are enabling this increment on mouse wheel feature and behave differently comparing to a plain HTML page.
<!DOCTYPE html>
<html>
<body>
<input
type="number"
min=0
max=99999
step=1
/>
</body>
</html>
I am not sure where you tried the .html but it seem to have the same behaviour on scroll. Check the codepen link.

However when I tried to render the .html on my local chrome browser, the scroll was not working and same with the React. Neither of them responded to scroll on local browser. I am not sure how the environments differ.
Bracket syntax is not valid HTML. They're used in JSX to insert javascript code inside HTML syntax, but obviously that will not work in pure HTML.
The equivalent HTML would be:
<!DOCTYPE html>
<html>
<body>
<input
type="number"
min="0"
max="99999"
step="1"
/>
</body>
</html>
Working example
Note that in both cases (React and HTML), the input needs to have focus for scrolling to work. This ability to scroll might also be a browser-dependent behavior.
Also, note that if you inspect the HTML that's being output by your React example, you'll see the same HTML that I've written above, so this is definitely not a behavior specific to React.
I want to add a slider as in input on a web page I am designing. I don't even know if it is called a slider.
A "slider" is written like this but within <> tags:
<input type="range" min="5" max="10" step="0.01">
You can set step to 1 and set the minimum and maximum values however you want.
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/range
If you're looking for two sliders, you can build it out of two sliders like this:
<input value="500" min="500" max="50000" step="500" type="range">
<input value="50000" min="500" max="50000" step="500" type="range">

I'm working on making client side validation for inputs.
I had had been using PHP to do it all.
Needless to say things got cluttered very quickly.
So I looked in to JS and HTML5 and want to move in to that system for validation.
The messages I want to show are like this:
I know that these are done with the the <input type="email"> tag.
After some help, I was pointed to this page html5rocks.
However I cant seem to get anything to popup.
I copied code straight from there site and nothing.
<input id="foo" type="number" max="2" value="1" />
<input id="bar" type="number" max="2" value="3" />
<script>
document.getElementById('foo').validity.rangeOverflow; //false
document.getElementById('bar').validity.rangeOverflow; //true
</script>
What am I missing to make the notification appear?
That popup is a new implementation in HTML5. Just create an input field like this:
<input type="email">
The popup appears automatically when the form is submitted if the input isn't an email-address.
More about the new input fields in HTML5 is at W3Schools.
Form must be submitted before validation kicks in.
So you have to add a button with the type of submit so like so:
<input type="submit" value="blah">
And then you have to enclose all the fields/inputs in a <form> and </form> tag.
here is the working code:
<form>
<input id="foo" type="number" max="2" value="1" />
<input id="bar" type="number" max="2" value="3" />
<input type="submit" value="blah">
</form>
<script>
document.getElementById('foo').validity.rangeOverflow; //false
document.getElementById('bar').validity.rangeOverflow; //true
</script>
