I have a basic form input for a number. The form works. The field will not accept letters being type into it. But the increment arrows that usually show up for type="number" aren't showing up. What am I missing?
<div>
<input
type="number"
id="cost"
className="form-field"
placeholder="Cost"
min="0"
onChange={handleChange}
value={hats.cost}/>
</div>
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?
This may be a silly thing to ask but I have the following:
<input ng-model="product.quantity" min="1" type="number" id="quantity" name="quantity" value="1" />
But I can't get the form starts blank.
How can I ensure that the form will be filled with, at least a value of "1"?
The form value is being set by the ngModel value and will ignore the value attribute. Set your model!
$scope.product.quantity = 1;
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 />

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" />
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
