vue输入节流,避免实时请求接口的实例代码

/
  @param func 输入完成的回调函数
  @param delay 延迟时间
 /
export function debounce(func, delay) {
 let timer
 return (...args) => {
  if (timer) {
   clearTimeout(timer)
  }
  timer = setTimeout(() => {
   func.apply(this, args)
  }, delay)
 }
}

<template>
 <div class="xn-container">
  <input type="text" class="text-input" v-model="search">
 </div>
</template>

<script>
 import {debounce} from '../utils/debounce'
 export default {
  name: 'HelloWorld',
  data () {
   return {
    search: ''
   }
  },
  created() {
   this.$watch('search', debounce((newQuery) => {
    // newQuery为输入的值
    console.log(newQuery)
   }, 200))
  }
 }
</script>

<!-- Add "scoped" attribute to limit CSS to this ponent only -->
<style scoped>
 .text-input {
  display: block;
  width: 100%;
