v-for 创建 ref

 <el-form :model="item" :rules="state.rules" :ref="el => getRiskSpreadRef(el, index)" ></el-form>

// 定义ref list
const riskSpreadRefList = ref<HTMLElement[]>([]);

// ref存到数组
const getRiskSpreadRef = (el, index) => {
  if (el) {
    riskSpreadRefList.value[index] = el; 
  }
};



// 使用

console.log(riskSpreadRefList.value[index])
