基于JavaScript实现生成名片、链接等二维码

<div id = "qrcodeid"></div> //生成的二维码放在此 div 中<script type="text/javascript" src="js/jquery.qrcode.min.js"></script>//引入qrcode.js（到https://github.com/jeromeetienne/jquery-qrcode 下载 ）<script>function utf16to8(str) { //解决中文乱码  var out, i, len, c;   out = "";   len = str.length;   for(i = 0; i < len; i++) {   c = str.charCodeAt(i);   if ((c >= 0x0001) && (c <= 0x007F)) {     out += str.charAt(i);   } else if (c > 0x07FF) {     out += String.fromCharCode(0xE0 | ((c >> 12) & 0x0F));     out += String.fromCharCode(0x80 | ((c >> 6) & 0x3F));     out += String.fromCharCode(0x80 | ((c >> 0) & 0x3F));   } else {     out += String.fromCharCode(0xC0 | ((c >> 6) & 0x1F));     out += String.fromCharCode(0x80 | ((c >> 0) & 0x3F));   }   }   return out; } </script><script>//此处生成名片二维码（如要生成普通链接二维码 则 “text”参数值 直接替换成普通链接即可）var the_text = "BEGIN:VCARD /r/nFN:姓名 /r/nTEL;CELL,VOICE:15000000000 /r/nTITLE:职称 /r/nORG:公司（组织） /r/nEMAIL;INTERNET,HOME:123@qq.com /r/nADR;WORK,POSTAL:地球中国山东... /r/nURL:http://leerd.cn /r/nEND:VCARD";the_text = utf16to8(the_text);//alert(the_text);jQuery('#qrcodeid').qrcode({width:140,height:140,render:"canvas", //设置渲染方式 table canvastypeNumber : -1,  //计算模式 correctLevel  : 0,//纠错等级 background   : "#ffffff",//背景颜色 foreground   : "#000000",//前景颜色 text:the_text}); </script>
