pc端下载图片

移动端一般图片长按会有保存的选项，所以只做pc端了

<template>
  <div>
      <img :src="pic" @click="fun" alt="">
  </div>
</template>
<script>
import pic from '@/static/2.jpg'
export default {
  data(){
      return{
          pic:pic
      }
  },
  mounted(){
    
  },
  methods:{
      fun(){
          var a = document.createElement('a')
          a.download = 'yh'
          // 设置图片地址
          a.href = this.pic;
          a.click();
      }
  }
}
</script>
<style scoped>


</style>
