[Element Warn][Form]model is required for validat
如文末的完整例子:
该提示说的是 form表单需要一个绑定一个 对象(使用:model="editform" 不能使用v-model="editform"),
同时v-model="multipleSelectionStudent" 的multipleSelectionStudent一定一定一定要在editform对象中,
而例子中v-model="multipleSelectionStudent" 的multipleSelectionStudent就不一定在editform对象中,因为此字段,没有做验证.
<el-form :model="editForm" ref="form" label-position="left" label-width="100px">
<el-row :gutter="24">
<el-col :span="12">
<el-form-item label="姓名">
<el-input v-model="multipleSelectionStudent" placeholder="请选择"></el-input>
</el-form-item>
</el-col>
<el-col :span="12">
<el-form-item label="地区" prop="selectSources" :rules="[
{ required: true, message: ‘请选择地区‘, trigger: ‘change‘}]">
<el-cascader v-model="editForm.selectSources"
placeholder="请选择"
:clearable="true"
:options="options.resourceGroup"
change-on-select
:props="cascaderProp"
class="el-cascader-100p"
></el-cascader>
</el-form-item>
</el-col>
</el-row>
</el-form>
export default {
data():{
return {
editForm: {
selectSources: [],
},
}
}
}
使用饿了么ui表单验证报错: [Element Warn][Form]model is required for validat
