使用到qrcode.js生成二维码
pako.js压缩字符串:https://github.com/nodeca/pako
参照代码如下：

原始:
<div id="qrcode"></div>
压缩后:
<div id="qrcode2"></div> <script> //var ticketData = 'http://www.baidu.com/efying/com/aa/d/sfa/sf.do?safafasdfasfdfhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhgggggggggggggggggggggggggggggggsafafasdfasfdfhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhgggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg';
var ticketData = 'www.baidu.com';
var data = zip(ticketData);
console.log("压缩后:");
console.log(data); var s = unzip(data);
console.log("解压后:");
console.log(s); var qrcode = new QRCode(document.getElementById("qrcode"), {
width : 166,//设置宽高
height : 166 });
qrcode.makeCode(s); var qrcode2 = new QRCode(document.getElementById("qrcode2"), {
width : 166,//设置宽高
height : 166 });
qrcode2.makeCode(data); function unzip(b64Data) {
var strData = atob(b64Data); // Convert binary string to character-number array
var charData = strData.split('').map(function(x) {

var data = pako.inflate(binData); // Convert gunzipped byteArray back to ascii string:

return strData;
} function zip(str) {
var binaryString = pako.gzip(str, {

}); return btoa(binaryString);
