在普通表单中对输入框、选择框都有校验案例。

但是在自定义非空中如何进行校验官网并没有说明

关键代码 clearValidate 方法清除校验

 this.$refs.formValue.clearValidate('signinimg')

使用案例

<template><div class="stylebg"><Tabs icons="el-icon-shopping-bag-2" :arrs="tabs" /><!--表格  --><div style="margin-top: 20px"><el-form ref="formValue"  label-width="120px" :rules="rules" :model="formValue"><el-form-item label="标题" prop="title"><el-input v-model="formValue.title" placeholder="请输入标题"></el-input></el-form-item><el-form-item label="单选图"><div class="imagelist"><div class="imagelist imgbox" @click="uploadimg('img','1')" v-if="formValue.img"><el-image class="img" :src="formValue.img" fit="cover" ></el-image></div>  <div  style="border: 1px dashed #d9d9d9;" class="avatar-uploader"   @click="uploadimg('img','1')" v-else><i class="el-icon-plus" style="width: 100px;height: 100px;display: flex;align-items: center;justify-content: center;"></i></div></div></el-form-item><el-form-item label="多选图"><div class="imagelist"><div v-for="(item, i) in formValue.imgs" :key="i" class="imagelist imgbox"><el-image class="img" :src="item" fit="cover" ></el-image><img src="@/assets/close.png" class="close" @click="handleRemove(i)"/></div>  <div  style="border: 1px dashed #d9d9d9;" class="avatar-uploader"   @click="uploadimg('imgs','2')"><i class="el-icon-plus" style="width: 100px;height: 100px;display: flex;align-items: center;justify-content: center;"></i></div></div></el-form-item><el-form-item label="电子签名" prop="signinimg"><div  @click="signinVisible=true" style="width: 200px;background-color: #d9d9d9;"><el-image :src="formValue.signinimg" style="width: 200px;height: 100px;display: flex;align-items: center;justify-content: center;color: #999;"><div slot="error" > 点击签名 </div></el-image></div></el-form-item><el-form-item label=""><el-button type="primary" size="small"  @click="upform">确定</el-button><el-button type="primary" size="small"  @click.native="back">返回</el-button></el-form-item></el-form></div><el-dialog title="选择图片" :visible.sync="dialogVisible" width="900px"><uploadDialog  v-if="dialogVisible" @getPic="getPic" :chosetype="picChoseType"></uploadDialog></el-dialog><el-dialog title="电子签名" :visible.sync="signinVisible" width="700px"><signinDia @setsignin="setsignin"></signinDia></el-dialog></div></template><script>import wueditor from '@/components/wueditor.vue';
