element-ui动态新加一行，动态表单验证

先看效果图：

以上是一个表单，俱乐部的名称是必填的；俱乐部成员是一个table数据，至少有一个，且可以点击添加按钮添加多个 ，但动态添加的行都需要进行表单验证。这里演示说明，电话没有做正则验证。代码如下：

<template>
  <el-dialog :visible.sync="dialogVisible" width="50%">
    <el-form ref="myform" :model="myform" label-width="120px" :rules="rules">
      <el-form-item label="俱乐部名称" prop="jlbName">
        <el-input v-model="myform.jlbName" />
      </el-form-item>
      <el-form-item label="俱乐部成员">
        <el-button icon="el-icon-plus" type="success" size="mini" @click="chickPlus">添加</el-button>
        <el-table :data="myform.userList" align="center">
          <el-table-column label="姓名">
            <template slot-scope="scope">
              <el-form-item :prop="`userList.${scope.$index}.chinaName`" :rules="rules.chinaName">
                <el-input v-model="scope.row.chinaName" />
              </el-form-item>
            </template>
          </el-table-column>
          <el-table-column label="电话">
            <template slot-scope="scope">
              <el-form-item :prop="`userList.${scope.$index}.phone`" :rules="rules.phone">
                <el-input v-model="scope.row.phone" />
              </el-form-item>
            </template>
          </el-table-column>
        </el-table>
      </el-form-item>
    </el-form>
    <div slot="footer" class="dialog-footer">
      <el-button @click="dialogVisible = false">取消</el-button>
      <el-button type="primary" @click="handleCreate">保存</el-button>
    </div>
  </el-dialog>
</template>

<script>

  export default {
    data() {
      return {
        dialogVisible: true,
        myform: {
          jlbName: '',
          userList: [{
            chinaName: '',
            phone: ''
          }]
        },
        rules: {
          jlbName: [{ required: true, message: '必填', trigger: 'blur' }],
          chinaName: [{ required: true, message: '必填', trigger: 'blur' }],
          phone: [{ required: true, message: '必填', trigger: 'blur' }],
        }

      }
    },

    methods: {
      //添加一行
      chickPlus() {
        this.myform.userList.push({
          chinaName: '',
          phone: ''
        })
      },
      handleCreate() {
        this.$refs['myform'].validate((valid) => {
          if (valid) {
            console.log(this.myform)
          }
        })
      }
    },

  }

</script>

<style scoped>
</style>

从代码可以看出，在el-form-item标签中嵌套了el-table标签，在el-table中每一列又包含了el-form-item，也就需要对此进行验证。scope.$index表示每一行的索引值，而${scope.$index}结合prop就绑定了每一行每一列的验证。
