1、前端配置正则表达式入存入数据库，前端表单反显校验

 <script>const rgxFunc = new RegExp(item.fieldRegexp.trim());const rules=[];console.log('正则表达式', rgxFunc);console.log('正则表达式', rgxFunc.test('中文'));rules.push({message: item.regexpTip || '请输入正确格式',pattern: rgxFunc});
</script>

2、动态生成校验

     <divv-for="(item, index) in fillDataForm.fieldArray":key="'options' + index"class="flex option-box"><el-form-itemlabel="选项名：":prop="'fieldArray.' + index + '.label'":rules="rules"><el-inputv-model="item.label"maxlength="15"show-word-limitclearable/></el-form-item><el-form-itemlabel="选项值：":prop="'fieldArray.' + index + '.value'":rules="[{ required: true, message: '必填项', trigger: 'blur' }]"><el-inputv-model="item.value"maxlength="15"show-word-limitclearable/></el-form-item></div>
