Question

What is the best way to limit the date picker to only accept numbers and hyphens in the input field while blocking any other input in Vue?

I have been utilizing the vue2-datepicker npm package for handling dates. The date input currently accepts all alphabets, numbers, and special characters but I only want it to allow numbers, hyphens, and forward slashes. It's simple to achieve this using a regular HTML input field, but how can I implement this restriction in the date picker? Any assistance on this matter would be highly appreciated. Thank you in advance.

Here is the link to the npm package I am utilizing.

An image demonstrating the input field with various values being accepted.

Below are the tags and attributes I am employing:


        <date-picker
          :placeholder="fieldItem.name"
          v-model="fieldItem.value"
          format="MM-DD-YYYY"
          v-if="fieldItem.type == 'datePicker'"
          type="number"
        ></date-picker>

To achieve this, you can utilize scoped slots like so:

<date-picker
  format='MM-DD-YYYY'
  value-type='format'
  v-model='time'>
  <template #input='{ props, events }'>
    <input
      v-bind='props'
      v-on='events'>
  </template>
</date-picker>

For a full list of available slots with vue2-datepicker, check out the documentation here.

Now, you can intercept the input event and eliminate unwanted characters by modifying the code as follows:

<date-picker
  format='MM-DD-YYYY'
  value-type='format'
  v-model='time'>
  <template #input='{ props, events }'>
  <input
    v-bind='props'
    v-on='{
      ...events,
      input: event => handleInput(event, events.input)
    }'>
  </template>
</date-picker>

...
  methods: {
    handleInput (event, update) {
      let value = event.target.value.replace(/[^0-9/-]/g, '')

      // force Vue to refresh input after remove some characters
      this.$forceUpdate()

      // Apply new value to let vue2-datepicker continue its flow
      update(value)
    }
  }
...
