<number-input>
An input for numeric values.
Motivation
The normal input with type="number" is fairly good to use, but it has some flaws, because it should if wanted e.g.:
- prevent non numeric input
- guarantee live-data to be valid
- use the local decimal separator
- pad a value with
0(to a specific length) - size the input (according to it's length)
- overflow to minimum or underflow to maximum
- saturate to minimum or to maximum
- display a specified unit
- display a specified currencies
- can use percentage values and do have automatically the correct decimal value
This element wants to achieve that, by using the Intl.NumberFormat API. A more simpler element <integer-input> just uses integer values and doesn't use units or percent values.
Example
<span>using units: </span><number-input min="-150" step="0.15" max="300" pad-length="3" default="15" unit="°C"></number-input><br>
<span>in percent: </span><number-input min="-1" step="0.15" max="3" start-at="1" default="1" number-style="percent"></number-input><br>
<span>using currencies: </span><number-input min="0" step="0.01" always-sign start-at="1000" default="1000" use-grouping number-style="currency" currency="EUR"></number-input><br>
<span>as integer: </span><integer-input min="-150" step="15" max="300" default="15"></integer-input>Styling
