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

Get or set field value

The field value is stored as an integer. Get or set the Rating field value:

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

//set field value
fd.field('Field1').value = 2;

Handle change event

Execute a function when a field value has been changed:

fd.field('Field1').$on('change', function(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
var htmlField = fd.field('Field1').$el;

//access field's block, which includes title and control
var 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;

Get or set symbol settings

Symbol settings are stored as an object. Get or set symbol settings:

//return symbol settings as an object
fd.field('Field1').symbol;

//set symbol settings
fd.field('Field1').symbol = {size : 40, color: 'red', character : '☆'}

Get or set range

Get or set the maximum value for the Rating field:

//return range as an integer
fd.field('Field1').range;

//set range
fd.field('Field1').range = 8;
