使用 JSBarCode 创建条形码
Creating barcodes using JSBarCode
我正在使用 JSBarCode 来尝试为资产生成条形码。我需要能够创建静态条形码，然后我想我可以自己获得动态部分。到目前为止，我的代码是从上面 link 中找到的文档直接复制的。我认为文档会给出一个工作示例来作为我的代码的基础。也许我写错了代码，我有下面的代码，我已经为 jsbarcode 和 canvas.
安装了 NPM
服务器端代码：
var JsBarcode = require('jsbarcode');
var Canvas = require("canvas");
var canvas = new Canvas();
JsBarcode(canvas, "Hello");
JsBarcode(".barcode").init();
HTML:
<svg class="barcode"
jsbarcode-format="upc"
jsbarcode-value="123456789012"
jsbarcode-textmargin="0"
jsbarcode-fontoptions="bold">
</svg>
我在尝试 运行 我的节点应用程序时遇到错误。它很长，对我来说用处不大，但希望你们中的一个人能理解它。这是：

我在 2014 年构建了一个小型条码生成器，它可以执行 Code128。我正在清除代码上的灰尘并将其在 codepen 上流通。它是 100% 客户端，纯香草 Javascript。没有 jQuery，没有库，没有字体，不需要服务器。您可以 运行 它与 U 盘断开连接。所有条形码均由浏览器生成。
old code 应该可以在任何支持 javascript 的浏览器中运行，并且它会生成 HTML "img" 标签，因此您可以将结果嵌入 "div" 并显示在页面上，即使客户端关闭了 JS。这都是 MIT 许可证，因此您可以免费下载和使用，有或没有 U/I。
我正在开发一款打印条码表的应用程序，如果您正在批量发布条码，请继续关注。
您可以使用 jsBarcode library 执行此操作，请参阅下面的演示
JsBarcode(".barcode").init();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jsbarcode/3.8.0/JsBarcode.all.js"></script>

old code 应该可以在任何支持 javascript 的浏览器中运行，并且它会生成 HTML "img" 标签，因此您可以将结果嵌入 "div" 并显示在页面上，即使客户端关闭了 JS。这都是 MIT 许可证，因此您可以免费下载和使用，有或没有 U/I。
我正在开发一款打印条码表的应用程序，如果您正在批量发布条码，请继续关注。
您可以使用 jsBarcode library 执行此操作，请参阅下面的演示
JsBarcode(".barcode").init();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jsbarcode/3.8.0/JsBarcode.all.js"></script>
<svg class="barcode" jsbarcode-format="upc" jsbarcode-value="012345678912" jsbarcode-textmargin="0" jsbarcode-fontoptions="bold">
