vee-validate验证不为空后输入不进去

Question

代码如下：

<input type="text" name="attachmentName" class="form-control" v-model="caseAttachmentManage.attachmentName" autocomplete="off" placeholder="附件名称"  v-validate="'required'" :class="{'input': true, 'is-danger': errors.has('attachmentName') }"/>

                <span v-show="errors.has('attachmentName')"  class="text-danger" >{{ errors.first('attachmentName') }}</span>

输入框输入不进去，求解决办法

Answer 1

input的初始值要保证为一个字符串，不可以是 undefined, v-model="caseAttachmentManage.attachmentName"caseAttachmentManage.attachmentName 是否有初始定义为字符串
