在vue-cli中引入lodash.js并使用详解

<script src="https://cdn.jsdelivr./npm/lodash@4.13.1/lodash.min.js"></script>

$ npm i --save lodash

// Load the full build.
var _ = require('lodash');
// Load the core build.
var _ = require('lodash/core');
// Load the FP build for immutable auto-curried iteratee-first data-last methods.
var fp = require('lodash/fp');
 
// Load method categories.
var array = require('lodash/array');
var object = require('lodash/fp/object');
 
// Cherry-pick methods for smaller browserify/rollup/webpack bundles.
var at = require('lodash/at');
var curryN = require('lodash/fp/curryN');

<script>
let lodash = require('lodash')

export default {
 data () {
  return {
   firstName: 'Foo',
   lastName: 'Bar2',
   question: '',
   answer: 'ask me'
  }
 },
methods: {
 getAnswer: lodash.debounce(function () {
  if (this.question.indexOf('?') === -1) {
   this.answer = 'without mark'
   return
  }
  this.answer = 'Thinking...'
  var vm = this
  vm.$http.get('https://yesno.wtf/api').then(function (response) {
   vm.answer = lodash.capitalize(response.data.answer)
  })
   .catch(function (error) {
    vm.answer = 'error' + error
   })
 }, 500)
}
