微信小程序云开发后端开发框架没有自带的验证性能，因而开发校友录小程序的表单验证时候个别有两种办法，一是本人裸写验证规定，然而须要比拟扎实的正则表达式根底，一种是本人封装Validate插件进行表单验证，基于以上起因，小女子本人封装了云开发后端数据校验规定一套，并且与前端数据校验的写法和规定统一（前端数据校验体系下一篇笔记介绍：））
对立校验路由入口
function check(data, rules, that) { let returnData = {}; for (let k in rules) { let arr = rules[k].split('|'); let desc = ''; // 校友录小程序数据项阐明 for (let i = 0; i < arr.length; i++) { if (arr[i].indexOf('name=') > -1) { desc = arr[i].replace('name=', ''); break; } } //校友录小程序校验 let formName = arr[0]; let val = data[formName]; if (val === undefined) val = ''; if (!Array.isArray(val)) val = String(val).trim(); // 前后去空格 returnData[k] = val; for (let i = 1; i < arr.length; i++) { let result = ''; let rules = arr[i].split(':'); //校友录小程序空不校验 if (rules[0] != 'required' && val == '') continue; switch (rules[0]) { case 'required': result = checkRequired(val, desc); break; case 'array': result = checkArray(val, desc); break; case 'date': result = checkDate(val, desc); break; case 'time': result = checkTime(val, desc); break; case 'datetime': result = checkDatimeTime(val, desc); break; case 'min': result = checkMin(val, Number(rules[1]), desc); break; case 'max': result = checkMax(val, Number(rules[1]), desc); break; case 'len': result = checkLen(val, Number(rules[1]), desc); break; case 'in': result = checkIn(val, rules[1], desc); break; case 'email': result = checkEmail(val, desc); break; case 'mobile': result = checkMobile(val, desc); break; case 'int': result = checkInt(val, desc); break; case 'id': result = checkId(val, desc); break; case 'letter': result = checkLetter(val, desc); break; case 'letter_num': result = checkLetterNum(val, desc); break; } if (result) { wx.showModal({ title: '舒适提醒', content: result, showCancel: false, success(res) { //校友录小程序主动聚焦 if (that) that.setData({ [formName + 'Focus']: true }); } }); return false; } else { if (that) { // 删除原有的校友录小程序主动聚焦 if (helper.isDefined(that.data[formName + 'Focus'])) { that.setData({ //TODO delete? [formName + 'Focus']: false }); } } } } } return returnData;}分项数据校验实现
