I have a standard form with a slider:
`<input type="range" min="0" max="100" value="50" id="my_slider" name="my_slider">`
The value of the slider can be selected either with the mouse or with the arrow keys (after clicking on the slider). How can I disable the keyboard and force the user to position the slider with the mouse?
One possibility is obviously to disable the arrow keys on the whole page with Java Script, but I would like to avoid that if possible.
Thank you.
You can block the keys with onkeydown event...
<input type="range" min="0" max="100" value="50" id="my_slider" name="my_slider"
onkeydown="event.preventDefault()">
You can add a key listener to the input and call Event.preventDefault() on the event which will cancel it, preventing the default action from being triggered:
var mySlider = document.getElementById("my_slider");
mySlider.addEventListener("keydown", function(event) {
event.preventDefault();
return false;
});
<input type="range" min="0" max="100" value="50" id="my_slider" name="my_slider">

I have my web app working fine with computers, but can't seem to get it to work on mobile phones mainly because the onmouseup isn't being fired off. So I added the touchend event thinking it would be the same, but it didn't help. How do I get the same behavior of onmouseup on the phone?
Basically, I have a range slider and I want the release slider part of it to work on phones
<input id="slider" class="slider" type="range" min="0" max="100" value=50 onmouseup="handleSubmit()" touchend="handleSubmit()"/>
I've tried it on mobile safari and chrome... neither work
You don't need to rely on mouseup nor touchend. The input element offers another event which comes in handy: onchange.
This input fires as soon the input's value changed - because the user released the slider.
Here's an example:
function handleSubmit(e) {
console.log(e.value)
}
<input id="slider" class="slider" type="range" min="0" max="100" value=50 onchange="handleSubmit(this)" />
I'm stupid... it's supposed to be ontouchend
<input id="slider" class="slider" type="range" min="0" max="100" value=50 onmouseup="handleSubmit()" touchend="handleSubmit()"/>
still new to js haha
About Range input type in HTML
When I change value in slider (Range input type) that value in display in textbox
But when I also same thing in change value in textbox it’s not set that value in slider (Range input type).
Here is code
Function for it:
we also want that when we slide the slider as well as value will change in textbox too
function :
<script type="text/javascript">
function updateTextInput(val) {
document.getElementById('textInput').value=val;
}
function updateTextInput2(val) {
document.getElementById('range1').value = val;
}
</script>
HTML :
<input type="range" min="0" max="100" value="0" id="range1" onchange="updateTextInput(this.value);"/>
<input type="text" id="textInput" value="0" onchange="updateTextInput2(this.value);">
Debug the updateTextInput function to verify the value to set,
or try
document.getElementById('textInput').value = document.getElementById('range1').value;
You need to change the event where the function is called in the textbox from onchange to oninput. The onchange event only fires after the control loses focus, i.e. when the user clicks on something else. The oninput event gets fired every time the user changes the value in the textbox.
Your code should look like this:
<input type="range" min="0" max="100" value="0" id="range1" onchange="updateTextInput(this.value);" />
<input type="text" id="textInput" value="0" oninput="updateTextInput2(this.value);">
Your JavaScript functions work 100% fine.
Here is a working example on codepen.
I'm working on sliders with the jQuery sliders, I have a inout slider as
<form id="sliderData">
<input id="slider1" type="range" min="0" max="50" step="">
</form>
I want the slider to set up to only some fixed values as [2,30,20,30,35,45]. So I cannot set up the step value. I have tried to fire the event by this code
$('form#sliderData').change(function () {
alert("Hello");
});
This event is not even firing.Is there anyway to set slider to random values
The event is not being fired because you need to hook the change event to the slider control itself, not it's parent form.
The problem you have is that you cannot specify specific steps in a slider control. They must all be the same step apart from the min to the max values. To solve this you could instead make the values of the slider match the indexes of the values in your JS array, and have a label showing the actual option chosen. Something like this:
var values = [2, 30, 20, 30, 35, 45];
$('#slider1').on('input', e => $('span').text(values[e.target.value]));
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="sliderData">
<input id="slider1" type="range" min="0" max="5" value="0">
<span>2</span>
</form>
I've created the following code to show the user their range slider value. However, it only shows the value when the user stops moving the slider. Is there a way to show the value WHILE the user drags the range slider? I'm looking for a way to do this in vanilla JS.
function updateInput(val) {
document.getElementById('textInput').innerHTML=val;
}
<input type="range" name="rangeInput" min="0" max="100" onchange="updateInput(this.value);">
<p id="textInput"></p>
Here you go:
<input type="range" name="rangeInput" min="0" max="100" onchange="updateInput(this.value);" oninput="updateInput(this.value)" >
<p id="textInput"></p>
oninput is not supported in IE10, so you have to use both, oninput and onchange.
Here is the demo
Use oninput instead of onchange.
Magical proof!
onmousemove function make this happen:
<input type="range" name="rangeInput" min="0" max="100" onmousemove="document.getElementById('textInput').innerHTML=this.value;">
<p id="textInput"></p>
I am disabling my range input however in chrome it shows it grayed out but it is still usable.
<input type="range" disabled min="0" max="100"/>
I would assume the above would not allow you to change its value.
Am I doing it wrong?
jsFiddle
Relevant specification Disabled
Here is the Chrome bug report, guess just need to wait for version 15 as the commenters mentioned.
Bug 54820
you can remove all binded events of that specific scroll group to make that scroll disable like:
<div id="fieldset1">
<input type="range" disabled min="0" max="100" readonly="1"/>
</div>
<script>
$(":range").rangeinput();
$('#fieldset1 *').unbind(); // for all events
</script>
its works ..
no need to disable text field; beacause on form submission that field will not be posted ..
My solution JSFIDDLE (Works fine in default android browser)
html
<input id="range" type="range" value="10" min="0" max="30" step="10"/>
<button id="disableBtn">Disable</button>
JS
document.getElementById('disableBtn').addEventListener('input', filter);
document.getElementById('disableBtn').addEventListener('click', disable);
function disable(){
document.getElementById('range').disabled = !document.getElementById('range').disabled;
}
function filter(){
if(document.getElementById('range').disabled){
document.getElementById('range').value = document.getElementById('range').defaultValue;
}
}
I found a corny solution for chrome, because it doesn't seem like you can disable it from user input. Put a div over it so a user cannot interact with it. Not pretty but works:
<div style="position:relative;">
<div style="position:absolute;z-index:5;width:100%;height:100%;"></div>
<input type="range" disbaled=True min="0" max="100" value="0"/><span id="v">100</span>
</div>
