Issue
I am using the following script to show the barcode on the Invoice of my product SKU. But when I use the same script again to show the bar code for the product name{{ product.name }} and SKU barcode disappear, It only shows one barcode ie Product name barcode. How can I use the script to show multiple barcodes, for the product names and SKU?
FYI: I have no knowledge of codes.
<script src="https://cdn.jsdelivr.net/jsbarcode/3.3.20/JsBarcode.all.min.js"></script>
<h1><img id="upc"/><script> $('#upc').JsBarcode("{{ product.sku }}",{width:1,height:50,lineColor: "#333333" }); </script></p></h1>
Solution
First I would say, learn how to use HTML, script and other code! Second (also said already), use correct code.
- add the script to your template (only once!), like:
<script src="//cdn.jsdelivr.net/npm/jsbarcode@3.11.5/dist/JsBarcode.all.min.js"></script>
Do that at the end of the template.
- use correct HTML-Code, e.g.
<svg class="barcode" jsbarcode-format="code128" jsbarcode-value="{{ item.model }}"></svg>
beside each position the barcode shall be displayed.
- call the script and init it:
<script>JsBarcode(".barcode").init();</script>
at the end of your template.
- (optional): style your barcode output, according explained here: JSBarcode
p.s.: what I would do, is to store the jsbarcode script locally and call the local stored script.
I know many users intend to use cdn sources. Nice, but not effectful, imagine you want to diplay your solution locally without any internet connection. Or - think about the massive outfall a few weeks ago, where important sources were not reachable.
What you have, is what you can control!
pps: the difference in using a dot instead a # is, # indicates an ID, where the dot is simply a CSS-Class.
