Barcode field

The Barcode field allows a user to scan a code with a device camera. The scanned data is then populated into the field as plain text. A user can also manually edit the value by clicking the Edit button.

The scanner supports various types of barcodes. The type of barcode a user can scan can be defined in the field properties.

This page contains a detailed description of the field properties and JavaScript samples which you can use with this field.

JavaScript framework

In this section, you can find basic examples of how to work with the field using JavaScript.

For more examples, check out Working with form fields in JavaScript article. If you are not familiar with the JavaScript framework, get started with the JavaScript basics.

Note

The field is only accessible once the form is rendered, so all calls to the field must be inside fd.rendered event:

fd.rendered(() => {
    // access the field's value and print in the browser's console
    console.log(fd.field('Field1').value);
});

Get or set field value

Get or set the Barcode field value:

// get field value
fd.field('Field1').value;

// set field value
fd.field('Field1').value = 'New Value';

Handle change event

Execute a function when a field value has been changed:

fd.field('Field1').$on('change', value => {
    // log changes to browser's console
    console.log('New value: ' + value);
});

Make field required

Make a field required or optional:

// make field required
fd.field('Field1').required = true;

// make field not required
fd.field('Field1').required = false;

Disable field

Make a field non-editable. The field value can still be changed with JavaScript and saved:

// disabled field
fd.field('Field1').disabled = true;

// enable field
fd.field('Field1').disabled = false;

Get HTML element

Access HTML element inside the field in order to modify it, hide it, or do something else.

// access field's control
let htmlField = fd.field('Field1').$el;

// access field's block, which includes title and control
let htmlFullField = fd.field('Field1').$parent.$el;

Hide field

Hide a field from a user. The field value can still be accessed and changed with JavaScript:

// hide field
fd.field('Field1').hidden = true;

// show field
fd.field('Field1').hidden = false;
