lodash
是一个一致性、模块化、高性能的 JavaScript 实用工具库。
在vue官方文档中使用了lodash中的debounce函数对操作频率做限制。其引入的方式是直接引入了js
<script src="https://cdn.jsdelivr.net/npm/lodash@4.13.1/lodash.min.js"></script>
而现在我们使用vue-cli脚手架搭建的项目在这样使用，明显会很不合适。所以我们需要通过npm来安装
$ npm i --save lodash
然后在项目中通过require去引用
// 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');
引用在当前组件即可，如在App.vue中引用
<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)
}
