使用jquery.qrcode.min.js实现中文转化二维码

今天还是要讲一下关于二维码的知识，前几篇讲解中有讲到我使用的可以生成二维码的js是qrcode.js，然后结合Cordovad的插件$cordovaBarcodeScanner插件可以扫描二维码，这样就基本完成了简单的扫一扫功能。后来在项目进行，开始要调用后台数据和传参数到接口的时候发现qrcode.js它只能解析英文或者数字，并且只能解析一个字符串！

      而我所需要的是将一个对象转化成二维码，然后在扫描的时候取出对象中的数据，显然qrcode.js不能实现，经过查找，找到另一个jquery.qrcode.min.js(支持中文转化二维码).

     下面让我来介绍一下具体的步骤和代码实现吧！

一、这是我找到的jquery.qrcode.min.js(支持中文转化二维码)代码，需要引入到你的项目里去：
