How to set html input type number, max value such that the max value is less than boundary (max) value not equal to boundary value? Now what I can the do is as following but thats not the right solution because the list will go on
<input type="number" min="0" max="24" />
How to can I accept any value between 0 - 24 not 0 or 24
<input type="number" min="0" max="23.9">
or
<input type="number" min="0" max="23.99">
or
<input type="number" min="0" max="23.999">
or
<input type="number" min="0" max="23.999">
or
<input type="number" min="0" max="23.9999">
I need to accept floating values, options other than regex
You can give the input a step to define the increments.
<input type="number" min="0" max="23.99" step="0.01">
input number should not allow number to type more than the maximum value please check my below code it will help you for sure.
$("[type='number']").keypress(function (evt) {
console.log(evt.key);
var regex = /[0-9]/;
if(regex.test(evt.key) ) {
let value = parseInt($("[type='number']").val()+evt.key);
console.log("value",value);
value <= 24 ? "" : evt.preventDefault();
}
else
evt.preventDefault();
});

I have an HTML input that accepts decimal numbers starting from 0.001. The problem is when the user clicks the down arrow it starts from -0.001. How can I avoid the negative ??
<input type="number" name="amount" placeholder="0.001" step="0.001" required>
Set the attribute min:
<input type="number" name="amount" min="0.001" placeholder="0.001" step="0.001" required>
JSFiddle: https://jsfiddle.net/6spubgjm/
You can add a min attribute of 0 to fix this.
<input type="number" name="amount" placeholder="0.001" step="0.001" min="0" required>
<input type="number" name="amount" placeholder="0.001" step="0.001" min="0" required>
You can use min property
<input type="number" min="0" name="amount" placeholder="0.001" step="0.001" required>
<input type="number" name="amount" placeholder="0.001" step="0.001" min="0.001" required>
How do I code script that compares a a range slider value with 49. If more than 49 if shows true, if less than 50 displays false.
<input type="range" min="0" max="100" id="var1" step="1">
Assuming you want something to change while when the user changes the slider, try this
window.onload=function() {
document.getElementById("number").onchange=function() {
document.getElementById("rngnum").innerHTML=this.value<49?"False":"True";
}
document.getElementById("number").onchange(); // trigger when loaded
}
<input type="range" min="0" max="100" id="number" step="1" value="50"><label for="number" id="rngnum"></label>
If you just need to interrogate it:
var lessthan49=parseInt(document.getElementById("number").value)>49?true:false;
The increment and decrement button doesn't work.
<input type="number" min="0" value="0">
<label for="movie">How often you watch movie in week : </label><input id="movie" type="number" value="0"/>

I have to set limit of input number limit so that user can type only 3 numbers.
here my input tag:
<input type="number" name="age" id="age" class="inPadd" maxlength="3">
You should use attributes min="0" and max="999" instead of maxlength
<input type="number" name="age" id="age" class="inPadd" min="0" max="999">
I'm using this code:
<input type="range" min="1" max="100" name="points">
How do I display the current value in the slider?
If you want to display the concrete number you could have a span or something over top the input and use jquery to handle the onchanged event.
HTML:
Price: <input id="price" type="text" value="10.50" readonly /><br/>
Quantity: <input id="qty" type="text" value="1" readonly />
<input id="rangePoints" type="range" min="1" max="100" value="1"/><br/><br/>
Total Price: <input type="text" id="total" readonly />
JS:
$(function() {
$("#rangePoints").change(function() {
var qty = $("#rangePoints").val();
var price = $("#price").val();
$("#qty").val(qty);
$("#total").val(qty*price);
});
});
Working JsFiddle
The range input type is supported only by newer browsers. But with a bit of JavaScript magic you can make it accessible for older browers too, you don't even need jQuery in order to do this.
In JavaScript, add the following snippet:
function updateCurrentValue(val) {
document.getElementById('currentValue').value=val;
}
And then, in the HTML add another input element where to show the current value of the slider:
<input type="range" min="1" max="100" name="points" onchange="updateCurrentValue(this.value);">
Current value: <input type="text" id="currentValue">
