这里涉及到动态input表单校验 我仅给自己记录一下
<!-- 动态添加行 -->
<a-form-model-item
:wrapper-col="newWrapper"
style="padding-left:63px;padding-right:40px;"
v-for="(item, index) in form.information"
:key="item.key"
>
<a-form-model-item class="fl" :prop="'information.' + index + '.name'"
:rules="{
required: true,
message: '店铺名不能为空',
trigger: ['blur','change'],
}">
<a-input
v-model.trim="form.information[index].name"
placeholder="请输入店铺名称"
style="margin-right: 1%"
/>
</a-form-model-item>
<a-form-model-item class="fl" :prop="'information.' + index + '.address'"
:rules="{
required: true,
message: '店铺地址不能为空',
trigger: ['blur','change'],
}">
<a-input
v-model.trim="form.information[index].address"
placeholder="请输入店铺地址"
style="margin-right: 1%"
/>
</a-form-model-item>
<a-form-model-item class="fl" :prop="'information.' + index + '.storeManagerName'"
:rules="{
required: true,
message: '店长姓名不能为空',
trigger: ['blur','change'],
}">
<a-input
v-model.trim="form.information[index].storeManagerName"
placeholder="请输入店长姓名"
style="margin-right: 1%"
/>
</a-form-model-item>
<a-form-model-item class="fl" style="margin-right: 3%;" :prop="'information.' + index + '.storeManagerPhone'"
:rules="[{required: true,message: '店长手机不能为空',trigger: ['blur','change']},
{validator: mobilephoneValidate,trigger: ['blur','change'] }]"
>
<a-input
v-model.trim="form.information[index].storeManagerPhone"
placeholder="请输入店长手机号"
/>
</a-form-model-item>
<a
v-if="form.information.length > 1"
:disabled="form.information.length === 1"
@click="removeRows(item)"
>删除</a>
</a-form-model-item>
添加 删除的方法
// 动态删除添加输入行
removeRows(item) {
let index = this.form.information.indexOf(item);
if (index !== -1) {
this.form.information.splice(index, 1);
}
},
addRows() {
this.form.information.push({
name: '',
address: '',
storeManagerName: '',
storeManagerPhone: '',
key: Date.now(),
});
},手机号或者其他单独的表单校验写在methods里
// 动态添加行 店长手机号验证
testMobilephone: function (str) {
const regex = /^1[3456789]\d{9}$/
if (!regex.test(str)) {
return false
} else {
return true
}
},
mobilephoneValidate (rule, value, callback) {
// 主要就是添加一个对undefined和空串的判断
if (typeof (value) === 'undefined' || value === '') {
callback()
} else {
if (!this.testMobilephone(value)) {
callback(new Error('请输入正确手机格式'))
}
callback()
}
},这里information数组 在data里写上一组空对象 是为了保证有一组input行显示出来 不写input行则会隐藏掉
