el-form多表单校验

思路：使用Promise.all以及elementui自带的表单校验去判断

<el-form ref="form" :model="formData">
    ....
</el-form>

<el-form ref="formTwo"  :model="formDataTwo">
    ....
</el-form>

<el-form ref="formThird"  :model="formDataThird">
    ....
</el-form>
...

      <span slot="footer" class="dialog-footer">
        <el-button @click="handleClickCancel">{{ '取消' }}</el-button>
        <el-button type="primary" @click="validFormHandle">{{ '确定' }}</el-button>
      </span>

需求：所有表单通过校验后才可以请求接口

    /**
     * @description: 确定的点击事件
     * @return {*}
     */
    validFormHandle() {
      Promise.all(['formData', 'formDataTwo','formDataThird'].map(item => this.validForm(item))).then(() => {
        this.handleClickOk()
      }).catch(error => {
        this.$message({
          showClose: true,
          message: '请先检查表单是否都已填写',
          type: 'warning'
        })
        console.log('error', error)
      })
    },
    handleClickOk() {
      const params = { ...this.formData, ...this.formDataTwo,...this.formDataThird }
//请求接口处理
xxx(params).then(res =>{
    this.$message.success(res.msg)
)
    },
    // 校验表单
    validForm(formRef) {
      return new Promise((resovle, reject) => {
        this.$refs[formRef].validate(valid => {
          if (valid) {
            resovle()
          } else {
            reject()
          }
        })
      })
    },
