JS - el-table - :row-key

  getRowKey(row) {
  /** 检查row.id是否有重复的缓存对象 */
  if (!this.checkRepeatObj) {
    this.checkRepeatObj = {}
  }
  if (row) {
    if (row.id) {
      if (this.checkRepeatObj[row.id]) {
        if (!row._secondId) {
          row._secondId = Math.random() + ''
        }
        /** 方便根据key重用元素 */

      } else {
        this.checkRepeatObj[row.id] = 1
        return row.id

el-upload - :before-upload 中 使用接口方法

beforeAvatarUpload (file) {
      let that = this
      return new Promise((resolve, reject) => {
        // 图片不能大于500k
        const isLt500K = file.size / 1024 / 1024 < 5
        let arr = file.name.split('.')
        let type = arr[arr.length - 1]
        let testmsg = /^(jpeg|png|jpg)$/.test(type)
        let name = file.name
        let nameArr = name.split('.')
        let url = '/person/validateIdNo'
        let param = {

        }
        // eslint-disable-next-line no-unused-vars
        let isName = false
        AxiosApi(url, {}, 'GET', param).then(res => {
