基于vue、iview单张图片、多张图片上传功能

效果展示：

复制代码立即可用，只需更改data中的图片上传的接口就可以了

1、demo.vue

2、js代码

export default {
  name: 'slideshow',
  data () {
    return {
      actionUrl: '服务器请求地此，上传文件的接口',
      imageUrl: '',
      hasImage: false,
      showImageUrl: '',
      visible: false,
      imageUrlList: [
        {
          url: '***.jpg'
        }
      ]
    }
  },
  methods: {
    handleMaxSize (file) {
      this.$Notice.warning({
        title: '图片大小限制',
        desc: '文件 ' + file.name + '太大,不能超过 2M.'
      })
    },
    upload () {
      this.loadingStatus = true
      setTimeout(() => {
        this.file = null
        this.loadingStatus = false
        this.$Message.success('Success')
      }, 1500)
    },
    handleView (imageUrl) {
      this.showImageUrl = imageUrl
      this.visible = true
    },
    handleRemove () {
      this.imageUrl = ''
      this.hasImage = false
    },
    handleRemoveList (index) {
      // 删除
      this.imageUrlList.splice(index, 1)
    },

    handleSuccessList (res, file) {
      let image = { url: res.data }
      console.log('image:' + image.url)
      this.imageUrlList.push(image)
      console.log(this.imageUrlList)
    },
    handleSuccess (res, file) {
      console.log(res)
      this.imageUrl = res.data
      this.hasImage = true
      console.log(file)
    }
  }
}

3、css

.demo-upload-list {
  display: inline-block;width: 60px;height: 60px;text-align: center;line-height: 60px;
