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

Get or set the Date and Time field value.

//return field value as a string
fd.field('Field1').value;

//set the field value to the current date
fd.field('Field1').value = new Date();

//set the field value to the specific date and time
fd.field('Field1').value = new Date(2021, 11, 24, 10, 33, 30, 0);

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;

Calendar start view

Specify the initial view of the calendar:

fd.field('Field1').widgetOptions = {

The following settings are available for the start property:

‘month’ - Shows the days of the month.
‘year’ - Shows the months of the year.
‘decade’ - Shows the years of the decade.
‘century’ - Shows the decades from the century.

Calendar navigation depth

Specify the navigation depth. By defining the start and depth properties for the calendar views, you can limit the navigation between views for a user.

//displays the calendar in decade view
//allows a user to select a date in month view
fd.field('Field1').widgetOptions = {
    start: 'decade',
    depth: 'year'
}

The start option must be greater than depth.

Always set both start and depth options.

‘year’ - Shows the months of the year.
‘decade’ - Shows the years of the decade.
‘century’ - Shows the decades from the century.

    disableDates: ['we', 'th', 'mon'],
}

//disables specific dates
fd.field('Field1').widgetOptions = {
    disableDates: [new Date(2024,6,1), new Date(2024,7,1)],
}

//disables specific dates and certain week days
fd.field('Field1').widgetOptions = {
    disableDates: function(date) {
        //dates to disable
        var dates = [new Date(2024,6,1), new Date(2024,7,1), new Date(2024, 9, 28)];
        if (date) {
            //disable Sunday (0), Saturday (6) and specified dates
            return date.getDay() === 0 || date.getDay() === 6 || dates.map(Number).indexOf(+date) >= 0
