网站抄袭/简易的旅游网页制作

项目需求：动态循环表单，并实现动态表单校验

页面：

		<u--form label-position="top" :model="tmForm" ref="tmForm" label-width="0px" :rules='rules'><div v-for="(element, index) in tmForm.tmList.filter((item) => item.delFlag !== 1)" :key="index"class="form-item"><div v-if="element.txTip == 'Input'">{{ element.tmTitle }}</div><u-form-item :required="element.pz.sfBt == '0'" :prop="`tmList[${index}].value`":label="`第${getFilteredIndex(index)}题`" v-if="element.txTip != 'Input'"><div class="tm-title">{{ element.tmTitle }}</div><div class="tm-sm" v-if="element.tmSm">题目说明：{{ element.tmSm }}</div><div class="tm-sm" v-if="element.txTip == 'Textarea'">题目规则：请填写『{{ element.pz.zfMin }} ~ {{ element.pz.zfMax }}』个字</div><div class="tm-sm" v-if="element.txTip == 'InputNumber'">题目规则：请填写『{{ element.pz.szMin }} ~ {{ element.pz.szMax }}』之间，小数点不超过{{element.pz.szDeciPlace}}位的数</div><div class="tm-sm" v-if="element.txTip == 'CheckBox' || element.txTip == 'twCheckBox'">题目规则：请选择『{{ element.pz.dxMin }} ~ {{ element.pz.dxMax }}』个选项</div><div class="tm-sm" v-if="element.txTip == 'TimePicker'">题目规则：请选择『{{ element.pz.rqMin }} ~ {{ element.pz.rqMax }}』之间的时间</div><div class="tm-sm" v-if="element.txTip == 'Upload'">题目规则：请上传『{{ element.pz.dxMin }} ~ {{ element.pz.dxMax }}』张图片</div><component style="margin-top: 10upx;" :optionList="element.optionList" :options="element.pz"v-model="element.value" :is="getWidget(element.txTip)"@updateValue="(newValue) => updateValue(element, newValue)"></component></u-form-item></div></u--form>

直接给rules里面循环加上校验规则，注意页面prop的写法  :prop="`tmList[${index}].value`"

	export default {data() {return {tmForm: {tmList: []},rules: {}}},mounted() {this.setRules()},methods: {// 循环设置rulessetRules() {this.tmForm.tmList.forEach((ele, index) => {this.$set(this.rules, `tmList[${index}].value`, [{validator: this.validate(ele),trigger: 'change'}])}),},// 表单验证方法validate(element) {return (rule, value2, callback) => {let value = element.value  //value2是空的，我手动赋值了if (element.pz.sfBt === '0' && (!value || value.length < 1)) {callback(new Error("请输入"));return;}if (element.txTip == "Textarea") {if (value && value.length > element.pz.zfMin) {callback(); // 通过验证} else {callback(new Error("文本长度不能小于10位"));}}if (element.txTip == "InputNumber") {const regex = new RegExp(`^-?\\d+(\\.\\d{0,${element.pz.szDeciPlace}}})*$`);// 判断是否在指定范围内且满足小数点位数要求if (value >= element.pz.szMin && value <= element.pz.szMax && regex.test(value)) {callback(); // 通过验证} else {callback(new Error(`请输入『${element.pz.szMin} ~ ${element.pz.szMax}』之间，小数点不超过${element.pz.szDeciPlace}位的数`)); // 验证失败}}if (element.txTip == "CheckBox" || element.txTip == "twCheckBox") {if (value.length >= element.pz.dxMin && value.length <= element.pz.dxMax) {console.log(1);callback(); // 通过验证} else {callback(new Error(`请选择『${element.pz.dxMin} ~ ${element.pz.dxMax}』个选项`)); // 验证失败console.log(2);}}if (element.txTip == "Upload") {const imageUrls = value.split(","); // 将图片 URL 字符串拆分为数组if (imageUrls.length >= element.pz.dxMin) {callback(); // 验证通过} else {callback(new Error(`请至少上传 ${element.pz.dxMin} 张图片`)); // 验证失败}}if (element.txTip == "Address" && element.pz.sfXxdz == "0") {if (value.value2) {callback(); // 验证通过} else {callback(new Error(`请填写详细地址`)); // 验证失败}}if (element.txTip == "PhoneNumber") {const reg = /^1[3-9]\d{9}$/; // 定义手机号码的正则表达式if (reg.test(value)) {callback(); // 验证通过} else {callback(new Error("手机号码格式不正确")); // 验证失败}}if (element.txTip == "IdNumber") {const reg = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/; // 定义身份证号码的正则表达式if (reg.test(value)) {callback(); // 验证通过} else {callback(new Error("身份证号码格式不正确")); // 验证失败}}if (element.txTip == "Email") {const reg = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$/; // 定义邮箱地址的正则表达式if (reg.test(value)) {callback(); // 验证通过} else {callback(new Error("邮箱地址格式不正确")); // 验证失败}}callback();};},}
