vue实现防抖的实例代码

const debounce=function(fn, delay){
	let timer = null
	return function(){
		let content = this;
		let args = arguments;
		if(timer){
			clearTimeout(timer)
		}
		timer = setTimeout(()=>{
			fn.apply(content,args)
		}, delay)
	}
}
export default debounce

<template>
 <div class="main">
  <el-input v-model="input" @change="changeSeletc" placeholder="请输入内容"></el-input>
 </div>
</template>
<script>
 import debounce from "../utils/debounce"
 export default {
  name: "alarm",
  data(){
   return{
    input: ''
   }
  },
  methods:{
   changeSeletc:debounce(function () {
    console.log(this.input)
   },500),
  }
 }
</script>
<style scoped>
</style>
