Vuelidate date input field


I hope someone can clarify to me, how to properly use Vuelidate while validating Date object. I want to use the current date as a minimal date, so if a user inputs a date later, an error will be shown.

I have an example: https://jsfiddle.net/cheslavcc/fns8eh0f/1/

Vue.use(window.vuelidate.default)
const { required, minValue } = window.validators

new Vue({
  el: "#app",
  data: {
    text: ''
  },
  validations: {
    text: {
        minValue: minValue(moment(new Date(), 'DD.MM.YYYY').format('DD.MM.YYYY')),
    }
  }
})

I'm using Moment.js as a date formatter, and minValue from the official Vuelidate documentation: https://monterail.github.io/vuelidate/#sub-builtin-validators

Any help appreciated, thanks a lot!


Solution

  • You can define custom validator:

    Vue.use(window.vuelidate.default)
    const { required, minValue } = window.validators
    
    const currentDate = moment(new Date()).startOf('day')
    const minDate = window.vuelidate.withParams({minDate: currentDate.format('DD.MM.YYYY')}, value => moment(value, 'DD.MM.YYYY', true).isSameOrAfter(currentDate))
    
    new Vue({
    	el: "#app",
      data: {
      	text: ''
      },
      validations: {
      	text: {
    			minDate
        }
      }
    })
    input {
      border: 1px solid silver;
      border-radius: 4px;
      background: white;
      padding: 5px 10px;
    }
    
    .error {
      border-color: red;
      background: #FDD;
    }
    
    .error:focus {
      outline-color: #F99;
    }
    
    .valid {
      border-color: #5A5;
      background: #EFE;
    }
    
    .valid:focus {
      outline-color: #8E8;
    }
