目前有一个需求，就是使用ant-desing for vue 1.7.8版本的框架做一个表单，但是在过程中出现了Bug，现在想要记录下来：
遇到的bug：我有一个下拉框，这个下拉框旁边有一个选择的弹出框，在弹出框点击确认后，可以赋值到下拉框，下拉框也可以选择，但是有一个bug，那就是如果我先在弹出框选择了，并且赋值了，这个时候我再在下拉框选择，会出现校验不通过，会有一个提示。后面修复了。

一、VUE 代码

我这里使用的a-form-model的表单，并且使用了循环

<div v-for="(form, formIndex) in formDataList" :key="form.tid" class="problem_form_wrapper"><div style="margin-bottom: 15px;text-align: right;"><a-button class="delete_btn" type="primary" @click="handleDelete(form.tid)" icon="delete">删除问题</a-button></div><div class="table-page-search-wrapper"><a-form-model :model="form" :ref="`form_${form.tid}`" layout="inline"><a-input v-decorator.trim="['planCode', planCode]" type="hidden"></a-input><a-input v-decorator.trim="['issuesId', form.issuesId]" type="hidden"></a-input><a-row :gutter="30" style="margin-bottom:

我上面的代码直接复制的，懒得删减。

二、方法

 //点击搜索弹出违章类型搜索openCode(index) {this.breakRuleVisibleCode = truethis.breakIndex = index},onSelect(value, index) {this.myMethod(value, index);const formRef = this.$refs[`form_${this.formDataList[index].tid}`];},myMethod(value, index) {let newData = this.viotionRecords.filter(item => item.code === value)[0];this.$set(this.formDataList[index], 'violationsCoding', value);this.$set(this.formDataList[index], 'violationsType', newData.violationsType);this.$set(this.formDataList[index], 'violationsPhenomena', newData.regulations);this.$nextTick(() => {const formRef = this.$refs[`form_${this.formDataList[index].tid}`]?.[index];formRef.clearValidate('violationsCoding')});this.$forceUpdate()},handleCancelBreak(record, index) {this.myMethod(record.code, this.breakIndex)this.breakRuleVisibleCode = false;

主要的解决方法就是用了同一个赋值的 方法，以前是分开的： this.myMethod(record.code, this.breakIndex)
