QR 不在电子邮件、铁路上展示的法规
原标题:QR Codes not displaying in emails, Rails

I m处理遗留铁路网站。 我试图将QR编码放在电子邮件中(通常在网站上操作),使用QRCode.js。

<% @tires.each do |tire| %>
  <h3>TIRE <%= tire.id %> QR CODE</h3>
  <div class="barcode-main" id="barcode_<%=tire.id%>"></div>
  <script> 
    var qrcode = new QRCode("barcode_<%=tire.id%>", {
    text: "http://jindo.dev.naver.com/collie",
    width: 128,
    height: 128,
    colorDark : "#000000",
    colorLight : "#ffffff",
    correctLevel : QRCode.CorrectLevel.H
    });
  </script>
<% end %> etc

在电子邮件检查中,内容是:

<div id="m_142369116572343918barcode_49"></div>

在《展望》检查中,内容是:

<div id="x_barcode_49"></div>

没有任何阶层,而且假肢在前被人改变。 通常作为附件并在其他地方进行。

...... 我现在还试图与RQRCode和谷歌图QR一样,可以让它们到网站上,但不能在电子邮件中展示。 随着RQRCode的出现,这些元素显示为<u>/u>和谷歌图R。

问题回答

我用了3千兆瓦的宝石,最后用QuickChart(didn tss QR被折旧)。
