I have a range input I use to filter my model which is binded to the value attribute.
{{input type="range" class="range" name="range" min="0" max="64" value=bindvalue}}
The problem is that it filters for every step you drag the slider, instead of just filter the value when you release the slider. Which really makes the slider lag.
So I thought I could use this instead:
<input type="range" onchange="number.value=value" name="range" min="0" max="64" value="0">
{{input type="number" id="number" name="number" value=bindvalue}}
The range input sets the number inputs value on release but ember doesn't update my filter when this happens. only when I edit the number input myself.
How would you go about letting ember know when the range input sets the number inputs value?
Regarding your last approach and if not debounce is used, as stated here
Ember.js textField change event
the field needs to lose focus.
So you can do something like,
function updateNumberValue(value){
var num=document.querySelector("#number");
num.value=value;
$(num).blur();
}

I didn't do too much but up and down arrow doesn't detect the changes when we type number manually it bind with totalQuantity but if we tries to use down or up arrow which is inside input box, it doesn't detect that value is changed. It shows me previous value
<input type="number" name="quantity" [(ngModel)]="totalQuantity" />
Can you check this in stackblitz.
https://stackblitz.com/edit/angular-z1ntzg?file=src%2Fapp%2Fapp.module.ts
For instance:
<input class="table-input" type="number" name="qty" [(ngModel)]="cpy.qty"
matInput min="1" max="{{cpy.qty}}"
where cpy is object.
And cpy.qty is changing dynamically. Now I have to perform operation on onInputChange
How to detect dynamically inputchange Value?
For dynamically changed value, you can handle change logic with ngDoCheck https://angular.io/api/core/DoCheck
Is it possible to have an input element with type equal to number, whose arrow buttons would change the value not by step attribute, but by other given number?
I need to have a field with step equal to .001, buy I'd like to make +-1 jumps by clicking arrows. (I ask aboout native arrow buttons, of course I can simulate them anyhow, but that's not the question.)
googling turned this up first
<input type="number" name="points" min="0" max="100" step="0.001" value="30">
Other than that, I guess you'll need to use JS to manipulate the behaviour. Maybe sth like:
<input id="example" type="number" name="points" step="0.001" onchange="checkChangedInput();">
<script>
function checkChangedInput() {
// check if number got lower or higher
...
document.getElementById("example").value += OldValuePlusZeroPointNineNineNine;
</script>
Though I guess using onchange might give unexpected results when sth is being typed in the field. So you should also check if in/decrement was more than your step(0.001).
This might yield some useful information as well: HTML5 input type=number change step behavior
I'm facing the issue for input field's attributes min and max values in Firefox (v_30.0) browser.
This works
<input name="year" type="number" placeholder="YYYY" required min="1" max="12"/>
But this does not
<input name="year" type="number" placeholder="YYYY" required min="1990" max="20014"/>
it displays 1 on input box and does not move further.
Firefox (unlike Chrome) seems to follow the HTML5 definition for stepping up the value of an input type=number element. When the value is not set, as it here isn’t initially, it is interpreted as 0, so the result of incrementing is 1. Since it is outside the range, it is an invalid value, and further stepping is not possible.
This means that input type=number is intended for use with quantities for which an initial value can be set (or the default initial value of 0 can be accepted). After all, stepping up and down is really the reason for using this element type, and it needs to start somewhere.
Consequently, there is not much point in using required for such an element, unless the implicit default of 0 is acceptable and within the bounds set.
If you still want to use input type=number, you need to set some initial value with the value attribute that is within the bounds. Technically, this means that the pattern attribute has no effect.
To read a required 4-digit number when no default value is set, optionally with a placeholder, you can use a text input field with suitable attributes (but you cannot express a range requirement in HTML, in any reasonable way, in this approach):
<input name="year" type="text" placeholder="YYYY"
size="4" maxlength="4" pattern="\d[4}" required
style="font-family: Consolas, monospace">
Just set the starting value and it will work
<input name="year" type="number" min="1990" max="2014" value="1990" required />
http://jsfiddle.net/ywq6dq93/
EDIT:
As another user previously pointed out, this will not show the placeholder but instead the starting value of 1990. In Chrome it works to not set the value and still show the placeholder and achieve the desired functionality, however it seems that in FF you would need to set the value by javascript when focusing on the input field, if you want to show a placeholder instead of a starting value.
Demo for this: http://jsfiddle.net/1pg5727f
<input type="number" step="1" min="1" name="product_qty" value="1" title="Qty" class="input-text" size="4" maxlength="10" pattern="\d*" required />
if you still looking for the answer you can use input type="number".
min max work if it set in that order:
1-name
2-maxlength
3-size
4-min
5-max
just copy it
<input name="X" maxlength="3" size="2" min="1" max="100" type="number" />
Hello and could make a required HTML5 in input type range
<form>
<input type="range" min="1" max="10" value="" required="required" />
<input type="submit">
</form>
The required attribute does not apply to an input element in Range state.
The value sanitization algorithm is as follows: If the value of the element is not a valid floating-point number, then set it to the best representation, as a floating-point number, of the default value.
The default value is the minimum plus half the difference between the minimum and the maximum, unless the maximum is less than the minimum, in which case the default value is the minimum.
Range state (type=range)
You will never reuire required attribute because Validation/required is irrelevant since a slider will always have a valid value - the UI slider does not allow for selecting invalid values.

This needs an answer. Required means required to be answered by a user through active participation, not because of default values on a scale.
ie. The rules of html forms were originally intended to follow survey and research methodology design principles, NOT coding quirks. HTML forms were built to meet real-world form requirements not the other way around.
If you create a form and want a range to be explicitly answered before the form can be submitted, you can add a self-contained workaround into the range input.
Simply do the following:
Add a standard text input field which is set to required but is hidden from view with with class=d-none / or css display:none. Do not use type=hidden, as this won't support this workaround. Insert this input after the input range field.
In the input type=range field, add a javascript method to remove the 'required' property of the hidden field with onChange.
in code terms:
<input type="range" id="rangeinput" name="rangeinput" min="0" max="50"
onchange="$('#'+this.id+' + input').prop('required',false);"
value="0">
<input type="text" class="d-none" value="" required>`
This will prevent the form from being submitted until the user changes the initial value of the range input. However, it will not 'focus' the range input to alert the user that this field was not attempted.
Feedback for the user can be provided, but depends on your preferred messaging approach.. whether it's toasts, popups, text fields, etc.
