话不多说先放几张图,首页的 css 是借鉴的,核心代码已经贴出.

Home 首页
selectAllRows: function (cb) {
pool.getConnection(function (error, connection) {
if (error) {
console.log('获取数据库连接失败');
throw error;
// return;
}
connection.query(sqlList.selectAllRowsData, function (error, result) {
if (error) {
console.log('查询失败');
throw error;
// return '查询失败';
}
if (result) {
try {
//result = JSON.stringify(result);
} catch (e) {
if (e) {
console.log(e.stack);
}
}
cb(error, result);
}
connection.release();
});
});
}
List 页面
selectAllRows: function (cb) {
pool.getConnection(function (error, connection) {
if (error) {
console.log('获取数据库连接失败');
throw error;
// return;
}
connection.query(sqlList.selectAllRowsData, function (error, result) {
if (error) {
console.log('查询失败');
throw error;
// return '查询失败';
}
if (result) {
try {
//result = JSON.stringify(result);
} catch (e) {
if (e) {
console.log(e.stack);
}
}
cb(error, result);
}
connection.release();
});
});
}
Update 页面
updateDataForAdmin: function (req, res, next, cb) {
pool.getConnection(function (error, connection) {
if (error) {
console.log('获取数据库连接失败');
throw error;
// return;
}
//获取请求参数
var param = req.body || req.params;
var date = new Date();
// 'update readinglist set title = ?, subtitle = ?, iconUrl = ?, editTime = ? where rid = ?'
connection.query(sqlList.updateData, [param.editTitle, param.editSubtitle, param.editIconUrl,date,param.rid], function (error, result) {
console.log('插入开始');
if (error) {
console.log('新增失败');
throw error;
// return;
}
// assert.ifError(error);
if (result) {
cb(req, res, error, result);
}
//formatData(res, result);
connection.release();
});
});
}
Delete 页面
deleteDataForAdmin: function (req, res, next, cb) {
pool.getConnection(function (error, connection) {
if (error) {
throw error;
console.log('获取数据库连接失败');
//return;
}
//获取请求参数
var param = req.param('rid');
console.log('参数为:' + param);
var comma = ',';
if (param.indexOf(comma) < 0) {
console.log('删除多个');//删除单个
connection.query(sqlList.deleteData, param, function (error, result) {
console.log('删除开始');
if (error) {
throw error;
console.log('删除失败', error);
//return;
}
if (result) {
cb(error, result);
}
connection.release();
});
}
else {
console.log('删除多个');//删除多个
var itemsCount = 0;
var items = param.split(',');
for (var i = 0; i < items.length; i++) {
//console.log('参数是一个数组' +param.length + "-----" + param[i].rid);
connection.query(sqlList.deleteData, items[i], function (error, result) {
console.log('删除开始' + i);
if (error) {
throw error;
console.log('删除失败', error);
//return;
}
if (result) {
itemsCount++;
console.log(itemsCount + '==========');
if (itemsCount == items.length) {
console.log('循环' + i);
cb(req, res, error, result);
connection.release();
}
}
});
}
}
});
}
配置的路由 js 如下:
var express = require('express');
var router = express.Router();
var dbDao = require('../db/DBDao');
var async = require('async');
/* GET home page. */
router.get('/', function (req, res, next) {
res.render('index', {title: 'Express'});
});
router.get('/showDetail', function (req, res) {
dbDao.selectAllRows(function (error, result) {
if (result) {
console.log('回调结果' + result);
res.render('detail', {
dataRows: result,
title: req.param('pagetype')
});
} else {
res.render('error', {});
}
});
});
router.post('/addData', function (req, res, next){
dbDao.insertDataForAdmin(req, res , next ,function(error, result){
if (result){
console.log('插入成功');
//重新查询,渲染页面
dbDao.selectAllRows(function (error, result) {
if (result) {
console.log('回调结果' + result);
res.render('detail', {
dataRows: result,
title: req.param('pagetype')
});
} else {
res.render('error', {});
}
});
}
});
});
router.get('/deleteData',function(req, res, next){
dbDao.deleteDataForAdmin(req, res , next ,function(error, result){
if (result){
//console.log('删除成功');
//重新查询,渲染页面
dbDao.selectAllRows(function (error, result) {
if (result) {
console.log('回调结果' + result);
res.render('detail', {
dataRows: result,
title: req.param('pagetype')
});
} else {
res.render('error', {});
}
});
}
});
});
router.post('/updateData',function(req, res, next){
dbDao.updateDataForAdmin(req, res , next ,function(error, result){
if (result){
//重新查询,渲染页面
dbDao.selectAllRows(function (error, result) {
if (result) {
console.log('回调结果' + result);
res.render('detail', {
dataRows: result,
title: req.param('pagetype')
});
} else {
res.render('error', {});
}
});
}
});
});
module.exports = router;
