一層循環嵌套時

<el-form :model="addform"
         ref="addform"
         :rules="rules">
  <el-form-item required
                label="姓名"
                v-for="(item, index) in addform.resourceList"
                :key="index"
                :prop="`resourceList.${index}.name`"
                :rules="rules.name">
    <el-input v-model="item.name"></el-input>
  </el-form-item>
</el-form>

?data數據結構及校驗規則

data() {
    return {
        addform: {
            resourceList: [{
                name: ''
            }]
        },
        rules: {
            name: [{
                required: true,
                message: '請輸入姓名',
                trigger: 'blur'
            }]
        },
    }
},

?prop應該寫成 如?:prop="'resourceList.' + index + '.name'"
?prop格式為?'遍歷的數組 . ' + 下標index + ' . 實際需要校驗的key'

多層循環嵌套時?

?prop應該寫成 如?:prop="'oneCycle.' + index + '.towCycle' + indexSon + ‘.sex’"
?prop格式為?'遍歷的一級數組 . ' + 下標index + ‘.遍歷的二級數組’+ 二級數組下標index + ' . 實際需要校驗的key'
