API & Demo

<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>
