@wslyhbb/vuejs-datepicker/src/utils/cellUtils.js

A simple Vue.js datepicker component. Supports disabling of dates, inline mode, translations. Fork of initial vuejs-datepicker which is abandoned.

const cellUtils = {
  isDefined (obj, prop) {
    return obj && typeof obj[prop] !== 'undefined'
  },

  hasArray (obj, prop) {
    return obj && Array.isArray(obj[prop])
  },

  hasDate (obj, prop) {
    return this.isDefined(obj, prop) && this.utils.isValidDate(obj[prop])
  },

  dayMonthYear (obj, prop) {
    const { utils } = this
    const hasDate = this.hasDate(obj, prop)

    if (!hasDate) {
      return {
        day: undefined,
        month: undefined,
        year: undefined
      }
    }

    const d = obj[prop]

    return {
      day: utils.getDate(d),
      month: utils.getMonth(d),
      year: utils.getFullYear(d)
    }
  }
}

export default (utils) => ({
  ...cellUtils,
  utils
})
