html端输入数据，利用qrcode.js生成打印二维码

在前端页面中导入qrcode.js（下载）和jquery.js（下载）

index.html

<script>
    function print() {
        var textbox1 = $('input[name="textbox1"]').val();
        if(!textbox1){
            alert("待生成的页面不能为空");
        }else{
            var symHref = 'print.html?id=' + textbox1;
            window.open(symHref);
        }
    }
</script>  

print.html

<script>
    var text = window.location.href.split('?')[1].split('=')[1];
    var text = decodeURI(text);
    var myDate = new Date();
    var time = myDate.getFullYear() + "-" + myDate.getMonth() + "-" + myDate.getDate();
    myHtml = "<div style='border:2px solid #000;width:405px;height:260px;position:relative;' class='demo'>"
        + "<div style='width:405px;margin-top:30px;'>"
        + "<table cellspacing=\"15px\";cellpadding=\"0px\";border=\"0\";>"
        + "<tr>"
        + "<td style='width:200px;font-size:10pt;text-align:left;font-weight:bold;font-family:微软雅黑;'>"
        + '当前日期：'
        + time
        + "</td>"

        + "</div>"
        + "<div style='z-index:-1;position:absolute; top:25px; right:-10px;'>"
        + create_qrcode(text, 9, "H", 4)
