Restrict Input Field To Only Allow Decimal Values – decimal-input

Preview:

Description:

decimal-input is a small JavaScript plugin that automatically formats and restricts the number input to only allow decimal values.

How to use it:

1. Download and insert the JavaScript decimal-input.js into the HTML file.

<script src="./decimal-input.js"></script>

2. Initialize the plugin on the number input and done.

<input class="decimal" type="number">

decimalInput();

3. Set the formatting type. Default: ‘standard’.

<input class="decimal" type="number" data-format="height">

// or
decimalInput({
  format: "height"
});

4. Set the number of decimal places. Default: 2.

<input class="decimal" type="number" data-length="3">

// or
decimalInput({
  length: 3
});

5. It also provides a basic validator for height, which can be used to correct feet and inches values.

decimalInput({
  validation: "soft" // or 'hard'
});

6. Override the default selector.

decimalInput({
  selector: ".decimal"
});
