Node實現搜尋框進行模糊查詢
阿新 • • 發佈:2021-06-29
本文例項為大家分享了Node實現搜尋框進行模糊查詢的具體程式碼,供大家參考,具體內容如下
一、需求
點選導航欄中的搜尋圖,出現搜尋框,從而進行文章的模糊查詢
二、建表
1.blog表
新增外來鍵:
2.nav表
3.type表
4.user表
三、頁面及樣式
like.e:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width,initial-scale=1.0"> <title>查詢</title> <link rel="stylesheet" href="//bootstrap.min.css" ><link rel="stylesheet" href="/css/index.css" > <script src="js/-3.3.1.min.js"></script> <script src="js/index.js"></script> </head> <body> <%-include('detachPart/nav.ejs')%> <%-include('detachPart/search.ejs')%> <div class="container"> <div class="row"> <div class="col-lg-9"> <%-include('bigPart/ownblog.ejs')%> </div> <div class="col-lg-3"> <%-include('smallPart/recommend.ejs')%> <%-include('smallPart/rank.ejs')%> <%-include('smallPart/rightimg_1.ejs')%> <%-include('smallPart/information.ejs')%> <%-include('smallPart/mylink.ejs')%> </div> </div> </div> <%-include('detachPart/footer.ejs')%> </body> </html>
search.ejs:
<div class="container searchclose"> <form action="/like" method="GET"> <input name="link" type="text" placeholder="請輸入關鍵字詞"> <input type="submit" value="搜尋"> <img class="closebtn" src="image/icon/close.png" alt="Node實現搜尋框進行模糊查詢"> </form> </div>
index.css:
.searchclose{ display: none; position: relative; margin: 0.5rem auto; padding: 1rem 0; text-align: center; background-color: white; } .searchclose input:nth-child(1){ width: 25rem; height: 2.2rem; outline: none; font-size: 0.9rem; padding-left: 0.5rem; border: 1px solid silver; box-sizing: border-box; vertical-align: middle; } .searchclose input:nth-child(2){ display: inline-block; width: 10rem; height: 2.2rem; line-height: 2.2rem; background-color: rgb(41,41,41);; color: white; vertical-align: middle; border: 1px solid rgb(41,41); border-style: none; margin-left: -1rem; } .searchclose img{ position: absolute; top: 0; right: 0; }
index.js:
$(function(){ $(".searchbtn").click(function(){ $(".searchclose").show(); }); $(".closebtn").click(function(){ $(".searchclose").hide(); }); });
四、www.cppcns.com資料
connection.js:
var mysql=require("mysql"); var setting=require("./setting"); var connection; var connectionmysql=function(){ connection=mysql.createConnection({ host:setting.host,port:setting.port,user:setting.user,password:setting.pwd,database:setting.base }); } connectionmysql(); exports.select=function(str,callback){ connectionmysql(); connection.query(str,function(err,res){ if(err) throw err; callback(res); connection.end(); }); } exports.find=function(str,params,res){ if(err) throw err; callback(res); connection.end(); }); }
sql.js:
module.exports={ findTitle:"select * from nav",clickRank:"select id,title from blog order by num desc limit 7",recommendInfo:"select id,title,logo,recommend from blog where recommend=1 limit 8",likeBlog:"select blog.id,intro,time,type.typeinfo,user.face from blog,type,user where blog.type=type.id and blog.face=user.id and title like ? order by time desc" }http://www.cppcns.com
promise.js:
var mysql=require("../MySQL/connection"); var sql=require("../MySQL/sql"); module.exports={ findTitle:function(){ return new Promise(function(resolve){ mysql.select(sql.findTitle,function(result){ resolve(JSON.parse(JSON.stringify(result))); }); }) },clickRank:function(){ return new Promise(function(resolve){ mysql.select(sql.clickRank,function(result){ resolve(JSON.parse(JSON.stringify(result))); }); }); },recommendInfo:function(){ return new Promise(function(resolve){ mysql.select(sql.recommendInfo,likeBlog:function(msg){ return new Promise(function(resolve){ mysql.find(sql.likeBlog,msg,function(result){ resolve(JSON.parse(JSON.stringify(result))); }); }); } }
router.js:
var promise=require("../MySQL/promise"); var url=require("url"); module.exports=function(app){ // 搜尋框進行模糊查詢 app.get("/like",function(req,res){ var likeurl=url.parse(req.url,true).query.link; async function getData(){ var res1=await promise.findTitle(); var res5=await promise.clickRank(); var res11=await promise.recommendInfo(); var res21=await promise.likeBlog("%"+likeurl+"%"); var allres={ titleindex:0,navres:res1,rankres:res5,recommendres:res11,blogres:res21 } return allres; } getData().then(function(result){ res.render("like",result); }); }); }
注:like 路由中的blogres:res21和首頁中的blogres:res10,所渲染到頁面中的資料名稱需一致,在此均為 blogres
五、效果展示
