elementUI的验证表单粗心导致的错误

<el-form v-show="!isLogin" :model="registerForm" status-icon :rules="registerRules" ref="registerForm" label-width="70px" class="demo-ruleForm">
          <el-form-item label="昵称" prop="registerNickName">

data里的if (!value) {

return callback(new Error('昵称不能为空'));
        } else {
          callback();
        }

callback();不能不写，否则提交会一直卡着
