<!--彈出二維碼--><div class="qrcode">    <div>        <p id="saoma">掃描二維碼</p>    </div></div>

js代碼：

$.ajax({     type: ‘POST‘,     url: ‘/house‘,     data: {          data:‘你的資料‘     },     dataType: ‘json‘,     success: function (data) {          if (data.code == 0) {               alert("成功");               $(‘#saoma‘).before(‘<img class="qrcode_show" src="/newQrCode?url=‘+ data.data +‘"/>‘);                        }else {               alert(‘失敗‘);          }     }})

nodejs:

var express = require(‘express‘);var request = require(‘request‘);var url = require(‘url‘);var qrImg = require(‘qr-image‘);
//產生二維碼app.get(‘/newQrCode‘, function (req, res) {    var par = url.parse(req.url, true).query;    var thisUrl = par.url;    var thisParam = par.id;    var imgUrl = thisUrl + ‘?id=‘ + thisParam;    var img = qrImg.image(imgUrl, { size: 10 });    res.writeHead(200, { ‘Content-Type‘: ‘image/png‘ });    img.pipe(res);});

var bodyParser = require(‘body-parser‘);var urlencodeRarser = bodyParser.urlencoded({ extended: false });app.post(‘/house‘,urlencodeRarser,function (req, res) {    var data = req.body;    var result = JSON.stringify({code:0, data:‘http://www.baidu.com/&id=‘ + data.data});    //console.log(result)    res.end(result);});
