mongodb模糊查询并分页

1.建立数据库

代码如下：

var mongoose = require('mongoose');var shortid = require('shortid');var Schema = mongoose.Schema;var IndexDataSchema = new Schema({ _id: { type: String, unique: true, 'default': shortid.generate }, type: String, city: String, name:string, value: [{name: String, value: String}], create: {type: Date, default: Date.now}, expand: String});IndexDataSchema.statics = { defaultSort: {'create': 1}, defaultOptions: {'pageSize': 0}};var IndexData = mongoose.model('IndexData', IndexDataSchema);module.exports = IndexData;

页面布局 这里只需要搜索框和搜索按钮，再点击按钮时，执行search()方法并发送请求

代码如下：

<div class="searchPart"> <input type="text" class="form-control" id="txtSearch" placeholder="请输入项目名称"> <button class="btn btn-success search_btn" onclick="search()">搜索</button> </div> <script> var paginObj; //设置每页显示页码 var pageSize = 20; //设置当前页码为1 var currentPage = 1; var condition = {'city': currentCityId, 'name': ''} jQuery(document).ready(function () { refresh(); }); //获取查找条件 function getCondition() { var name = $('#txtSearch').val(); if (name && name.trim()) { // {'$regex': name, '$options': 'i'}}为模糊查询固定语法，name为参数 condition = {'city': currentCityId, 'name': {'$regex': name, '$options': 'i'}}; } else { condition = {'city': currentCityId} } return condition; } //刷新页面 function refresh() { //查找内容 $.get('/Manage/list/projects', { 'pageSize': pageSize, 'currentPage': currentPage, 'condition': getCondition() }, function (result) { appendData(result.data); })//查找个数 $.get('/Manage/listCount/projects', {'condition': condition}, function (result) { paginObj = new DataPagin(document.querySelector('.projects-list'), result.count, { 'pageSize': pageSize, 'changePageFun': rquestPageData }); }) }//重新分页 function rquestPageData(currentPage, callback) { $.get('/Manage/list/projects', { 'pageSize': pageSize, 'currentPage': currentPage, 'condition': getCondition() }, function (result) { appendData(result.data); }) if (callback) { callback(); } }//改变页码，显示相应的内容 function changePage(paginObj, index) { paginObj.setPageNumber(index); } function appendData(data) { //debugger; var list = $('.projects-list').children('tbody'); list.html(''); // 页面显示模板 for (var i = 0; i < data.length; i++) { ......... //此部分自己定义 }) } //点击搜索按钮执行该方法 function search() { currentPage = 1; refresh(); }</script>

到数据库查找并返回相应内容

var formidable = require("formidable"); var common = require('./common'); var path = require("path"); var fs = require('fs'); var path = require('path'); var guid = require('guid'); var shortid = require('shortid'); var AuctionHouse = require('./db/IndexData'); var funs = { getList: function (collectionName, req, res, next) { var mainObj = transformCollctionName(collectionName); if (!mainObj) { next(); } var options = req.query; var sort = options.sort || mainObj.defaultSort; var pageSize = options.pageSize || mainObj.defaultOptions.pageSize; var currentPage = options.currentPage || 1; var condition = options.condition || {} //此部分为查找条件 mainObj.find(condition).sort(sort).skip((currentPage - 1) * pageSize).limit(pageSize).exec(function (err, docs) { if (err) { next(err); } return res.json(common.returnData(true, docs)); }) }, countList: function (collectionName, req, res, next) { var mainObj = transformCollctionName(collectionName); if (!mainObj) { next(); } var condition = req.query.condition || {} mainObj.find(condition).count().exec(function (err, docs) { if (err) { next(err); } return res.json({'count': docs}); }) }, HandleEvent: function (collectionName, actionsName, req, res, next) { var mainFuns = getCollctionFuns(collectionName) if (!mainFuns) { next(); } var fun = mainFuns[actionsName]; if (!fun) { next(); } fun(req, res, next); }
