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

Access and change field value with the following property:

//get field value
var text = fd.field('Field1').value;

//set field value to something, ignores the mask
fd.field('Field1').value = "L2H 3J3"

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;

Hide field

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

//hide field
$(fd.field('Field1').$parent.$el).hide();

//show field
$(fd.field('Field1').$parent.$el).show();

Get or set field mask

Access and change field Mask with the following property:

//get current field Mask
var text = fd.field('Field1').mask;

//set field value to something
fd.field('Field1').mask = "AAA AAA"
