jsBarcode生成条形码
1.pc端/移动端生成条形码
html
<svg id="svgcode">svg>
<canvas id="canvascode">canvas>
<img id="imgcode" />
js
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.3.min.js">script>
<script src="./jsBarcode.js">script>
<script type="text/javascript">
$("#svgcode").JsBarcode('123333');
$("#canvascode").JsBarcode('234234234');
$("#imgcode").JsBarcode("11111111");
script>
条形码样式设置
JsBarcode("#barcode", "11111", {
format: "pharmacode",
lineColor: "red",
width: 2,
height: 40,
displayValue: true
});
2.小程序端生成条形码
<canvas canvas-id="barcode" />
var wxbarcode = require('../../utils/barcode.js');//文章底部有补充代码
Page({
data: {
code: '121211212',
},
onLoad: function (options) {
this.barc('barcode', this.data.code, 680, 200);
},
barc(id, code, width, height) {
wxbarcode.code128(wx.createCanvasContext(id), code, this.convert_length(width), this.convert_length(height))
},
convert_length(length) {
return Math.round(wx.getSystemInfoSync().windowWidth * length / 750);
},
})
补充说明
生成的条形码不能使用微信进行扫描使用，只能自己编写扫码功能，扫描携带的内容。
如果要使用微信进行扫描显示商品需要：
1、去国家物品编码中心申请69商品条形码，费用自行查看。
2、申请好了之后，编码中心会给条码卡账号和密码，登陆国家后台进行备案。
3、1-2个工作日微信可以扫描出来，如果没显示，需要联系第3方。
