vue element项目中，提示框点击取消报错：Uncaught (in promise) cancel Promise.then (async)

解决方案： 加.catch(() => {})

this.$confirm(this.$t('message.delete'), this.$t('message.warning'), {
        confirmButtonText: this.$t('message.confirm'),
        cancelButtonText: this.$t('message.cancel'),
        type: 'warning',
        center: true
      }).then(() => {
        deleteRole(id).then(() => {
          this.$message({
            type: 'success',
            message: 'Success!'
          })
        })
        this.getRoleList()
      }).catch(() => {})
