使用方法：

1、head引入css文件

<style>
*{
	margin:0;
	padding:0;
}
body{
background-color: #262626;       
}
#box{
	width:1000px;
	height:600px;
	margin:200px auto;
}
#box .qrcode{
	width:400px;
	height: 400px;
	float: left;
	margin: 40px 40px;
}
#box .introduce{
	width:500px;
	height: 600px;
	float: left;
}
.introduce p{
	width:200px;
	height: 40px;
	background: #333; 
	float: left;
	margin:10px 20px;
	color:#fff;
	border-radius: 5px;
	overflow: hidden;
}
.introduce p span{
	float: left;
	width:50px;
	height:40px;
	color:#fff;
	text-align: center;
	line-height: 40px;
}
.introduce p input{
	width:150px;
	height:40px;
	float: left;
	border: 0;
	color:#fff;
	background:#000;
	text-indent:10px; 
	outline: none;
}
.introduce .btn{
	width:440px;
	height:40px;
	text-align: center;
	line-height: 40px;
	background: #6c0;
}
.qrcode>img{
	display: block;border:5px solid white;
}
</style>

2、head引入js文件

<script src="js/jquery.min.js"></script>
<script src="js/qrcode.js"></script>

3、body引入HTML代碼

<div id="box">
	<h3 style="color: aliceblue">請用微信搜生成的二微碼，查看效果</h3>
	<div class="introduce">
		<p>
			<span>姓名：</span>
			<input type="text" id="name" value="光頭強">
		</p>
		<p>
			<span>公司：</span>
			<input type="text" id="company" value="李老板伐木有限公司">
		</p>
		<p>
			<span>職務：</span>
			<input type="text" id="title" value="伐木員">
		</p>
		<p>
			<span>地址：</span>
			<input type="text" id="address" value="黑龍江省哈爾濱市南唐鎮狗熊嶺">
		</p>
		<p>
			<span>手機：</span>
			<input type="text" id="mobile" value="13818585858">
		</p>
		<p>
			<span>郵箱：</span>
			<input type="text" id="email" value="guangtouqiang@163.com">
		</p>
		<p>
			<span>網址：</span>
			<input type="text" id="web">
		</p>
		<p>
			<span>備注：</span>
			<input type="text" id="desc" >
		</p>
		<p class="btn">開啟通訊錄</p>
	</div>
	<div class="qrcode" id="qrcode"></div>
</div>


<script>
var name, company, title, address, mobile, email, web, desc;
$(".btn").click(function() {
	name = "FN:" + $("#name").val() + "\n";             //姓名
	company = "ORG:" + $("#company").val() + "\n";      //公司
	title = "TITLE:" + $("#title").val() + "\n";        //職務
	address = "WORK:" + $("#address").val() + "\n";     //地址
	mobile = "TEL:" + $("#mobile").val() + "\n";        //手機
	email = "EMAIL:" + $("#email").val() + "\n";        //郵箱
	web = "URL:" + $("#web").val() + "\n";              //網址
	desc = "NOTE:" + $("#desc").val() + "\n";           //備注

	var info = "BEGIN:VCARD\n" + name + company + title + address + mobile + email + web + desc + "END:VCARD";
	//console.log(info);
	//生成二維碼
	var qrcode = new QRCode("qrcode");
	qrcode.makeCode(info);

})
</script>
