Feature-rich Input Mask Plugin With Vanilla JavaScript – imaskjs

Preview:

Description:

imaskjs is a vanilla JavaScript input mask plugin that enables users to enter the data in a certain format.

Also works with Angular, React, React Native, and Vue.js.

Features:

• 2 built-in mask types: date and number
• Allows you to create mask rules using Regex or Function.

How to use it:

1. Insert the imaskjs library into the page.

<script defer src="https://unpkg.com/imask"></script>

2. Apply a custom mask to your input field using Regex.

<input id="example" type="text" value="">

var regExpMask = new IMask(document.getElementById('example'),{
    mask: /^[1-6]\d{0,5}$/
});

3. Apply the number mask to your number field.

<input id="example" type="text" value="">

var numberMask = new IMask(document.getElementById('example'), {
    mask: Number,
    min: -1000,
    max: 1000,
    thousandsSeparator: ' '
})

4. Apply the date mask to your date field.

<input id="example" type="text" value="">

var dateMask = new IMask(document.getElementById('example'),{
    mask: Date,
    min: new Date(2000, 0, 1),
    max: new Date(2020, 0, 1),
    lazy: false
})

5. Apply the enum mask to your input field.

<input id="example" type="text" value="">

var dateMask = new IMask(document.getElementById('example'),{
    mask: IMask.MaskedEnum,
    enum: ['F1', 'G2', 'H3'],
})

6. Apply the range mask to your input field.

<input id="example" type="text" value="">

var dateMask = new IMask(document.getElementById('example'),{
    mask: IMask.MaskedRange,
    from: 1,
    to: 90,
    maxLength: 3,
    autofix: true,  // bound value
})

7. Apply the Pattern Mask to your input field.

• 0 – any digit
• a – any letter
• * – any char
• [] – make input optional
• {} – include fixed part in unmasked value
• ` – prevent symbols shift back

<input id="example" type="text" value="">

var dateMask = new IMask(document.getElementById('example'),{
    mask: '{#}000[aaa]/NIC-`*[**]'
})

8. You can also apply multiple masks to the same field.

<input id="example" type="text" value="">

var dynamicMask = new IMask(document.getElementById('dynamic-mask'),{
    mask: [{
      mask: '+{1}(000)000-00-00'
    },
    {
      mask: /^\S*@?\S*$/
    }]
})

9. Available event handlers.

var myMask = new IMask()
.on('complete', function() {
  // do something
})
.on('accept', function() {
  // do something
})

10. Convert and format values.

var phonePipe = IMask.createPipe(
    phoneMask.masked,
    IMask.PIPE_TYPE.UNMASKED,
    IMask.PIPE_TYPE.MASKED
);
