clearable：清除 在框的末尾，鼠标移动到框末尾，会出现清除符，可清除框的内容

readonly：只读，框中内容不可编辑。对下拉框无效

filterable：下拉框的筛选属性，输入某字，可从下拉框模糊 筛选出相应的值 ，等同于 sql 中的like

 size="mini"：框 下拉框，都默认是最小的，比如，框的宽度会默认系统最小

js 方法

activated() {},


getNodeData(r) {
      this.city = r
      this.dialogVisible = true
    },
    putSuccess() {
      this.$message.success('成功!')
    },
    submitForm(formName) {
      this.$refs[formName].validate(valid => {
        if (valid) {
          this.dialogVisible = false
          this.$message.success('成功!')
        } else {
          this.$message.console.error('失败!')
          dialogVisible = false
          return false
        }
      })
    },
    resetForm(formName) {
      this.$refs[formName].resetFields()
      this.dialogVisible = false
    },

this.$refs：获取表单数据

activated：加载机制
