下载附件时防止连点

如果是button 直接加loading就能搞定

<el-button type="text" :loading="downLoading" @click="downloadFn(item)">下载</el-button>

 

如果是标签要加一个判断事件

<span v-loading="downLoading" class="downText" @click="downloadFn(item)">下载</span>

 

// 下载

    async downloadFn(file) {

      if (this.downLoading === false) {

        this.downLoading = true

        const res = await downloadFileByUniq(file.url)

        this.downLoading = false

        const blob = new Blob([res], { type: '' })

        const downloadElement = document.createElement('a')

        const href = window.URL.createObjectURL(blob)

        downloadElement.href = href

        downloadElement.download = this.$dayJs().format('YYYY-MM-DD HH:mm:ss') + file.name

        document.body.appendChild(downloadElement)

        downloadElement.click()

        document.body.removeChild(downloadElement)

        window.URL.revokeObjectURL(href)

      }

    },
