ElementUI中form表单组件自定义手机号验证规则

<el-form :model="ruleForm" status-icon :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
  <el-form-item label="手机号" prop="phone">
    <el-input type="text" v-model="ruleForm.phone"></el-input>
  </el-form-item>
  <el-form-item>
    <el-button type="primary" @click="submitForm('ruleForm')">提交</el-button>
    <el-button @click="resetForm('ruleForm')">重置</el-button>
  </el-form-item>
</el-form>

data(){
	//3.配置自定义规则
    let validatePhone = (rule,value,callback)=>{
      /*console.log(rule);
      console.log(value);
      console.log(callback);*/
      if (!value){
        callback(new Error('手机号不能为空！'));
      }
      //使用正则表达式进行验证手机号码
      if (!/^1[3456789]\d{9}$/.test(value)){
        callback(new Error('手机号不正确！'));
      }
    };
    return {
      rules: {
       //2.自定义验证规则
        phone: [
          { validator: validatePhone, trigger: 'blur' }
        ],
      },
      //1.表单数据
      ruleForm: {
        phone: ''
      }
    }
  },
