现在二维码越来越流行，很多网页都会有个二维码，扫描后可通过手机浏览。 以前做类似的项目一般是在网页上生成图片，然后把图片插入到网页。 这样做不能每个页面都生成二维码。jquery-qrcode是一个能够在浏览器端生成二维码的jquery插件。它是独立的，最小压缩之后不足4k，也没有图片下载请求。引入该类库之后，只需要一行代码，就可以很容易在web页面加上二维码。qrcode其实是通过使用jQuery实现图形渲染，画图，支持canvas（）和table两种方式，可以到/jeromeetienne/jquery-qrcode获取最新的代码。如何使用1、首先在页面中加入jquery库文件和qrcode插件&script type="text/" src="jquery.js"&&/script& &script type="text/javascript" src="jquery.qrcode.min.js"&&/script&2、在页面中需要显示二维码的地方加入以下代码：&div id="code"&&/div&3、调用qrcode插件qrcode支持canvas和table两种方式进行图片渲染，默认使用canvas方式，效率最高，当然要浏览器支持html5直接调用:$('#code').qrcode("http://www."); //任意字符串高级属性:$("#code").qrcode({ render: "table", //table方式 width: 200, //宽度 height:200, //高度 text: "" //任意内容 });

排队的时候你会发现一个规律：另一排总是动的比较快，当你换到另一排，你会发现，你原来站的那一排就开始动的比较快了。你站的越久，越可能感觉自己是站错了排。这就是神奇的墨菲定理。所以，不让自己后悔的最好办法，就是坚持。坚持你的人生梦想，而不去张望别人并受之影响。坚信自己当下的选择，不犹疑，不浮躁，心怀梦想，务实前行！相信成功就是将别人坚持不下来的事情坚持做下去。
