About CODE128

CODE128 is one of the more versatile barcodes. It has support for all 128 ASCII characters but does also encode numbers efficiently. It has three modes (A/B/C) but can switch between them at any time. CODE128 is the default barcode that JsBarcode will choose if nothing else is specified.

Supported modes

Auto (recommended)

JsBarcode("#barcode", "Example1234"); //CODE128 (auto) is the default mode
JsBarcode("#barcode", "Example1234", {format: "CODE128"}); //But you can still specify it

Forced modes

If the barcode scanner only support one type of CODE128 you can force that mode.

JsBarcode("#barcode", "EXAMPLE\n1234", {format: "CODE128A"});
JsBarcode("#barcode", "Example1234", {format: "CODE128B"});
JsBarcode("#barcode", "12345678", {format: "CODE128C"});
