生成二维码

直接在前台生成的不需要经过后台：所以用JS较多

<script src="~/Scripts/jquery-1.10.2.js"></script>
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script src="~/Scripts/framework-ui.js"></script>
<script src="~/Scripts/jquery.qrcode.js"></script>
<script src="~/Scripts/qrcode.js"></script>
<script src="~/Scripts/bootstrap.js"></script>
<script src="~/Scripts/jquery.validate.js"></script>

<script>
$(function () {
$('#qrcodeTable').qrcode({
render: "table",
text: "http://www.nfine.cn",
width: "265",
height: "265"
});
});
function createqrcode() {
if (!$('#form1').formValid()) {
return false;
}
$("#qrcodeTable").html("");
$('#qrcodeTable').qrcode({
render: "table",
text: $("#txt_barcod").val(),
width: "265",
height: "265"
});

 

}
</script>

<form id="form1">
<div class="mail-box">
<div class="mail-header">生成二维码</div>

 @*二维码测试 如需跳转则设置成http://www.baidu.com*@  
<div class="mail-body">
