#### First create a canvas (or image)
```html





``

#### Simple example:
``javascript
JsBarcode("#barcode", "Hi!");
// or with jQuery
$("#barcode").JsBarcode("Hi!");
``

##### Result:
!Result


#### Example with options:
``javascript
JsBarcode("#barcode", "1234", {
format: "pharmacode",
lineColor: "#0aa",
width:4,
height:40,
displayValue: false
});
``
##### Result:
!Result


#### More advanced use case:
``javascript
JsBarcode("#barcode")
.options({font: "OCR-B"}) // Will affect all barcodes
.EAN13("1234567890128", {fontSize: 18, textMargin: 0})
.blank(20) // Create space between the barcodes
.EAN5("12345", {height: 85, textPosition: "top", fontSize: 16, marginTop: 15})
.render();
``
##### Result:
!Result

#### Or define the value and options in the HTML element:
Use any jsbarcode- or data- as attributes where * is any option.
``html
jsbarcode-format="upc"
jsbarcode-value="123456789012"
jsbarcode-textmargin="0"
jsbarcode-fontoptions="bold">

``

And then initialize it with:
``javascript
JsBarcode(".barcode").init();
``

##### Result:
!Result

#### Retrieve the barcode values so you can render it any way you'd like
Pass in an object which will be filled with data.
`javascript
const data = {};
JsBarcode(data, 'text', {...options});
`
data will be filled with a ` encodings ` property which has all the needed values.
See wiki for an example of what data looks like.
