Button control

Properties

Here you can find properties specifically related to the Button control.

Name

A unique identifier for the control.

Name property

JavaScript

The Name property allows to work with the control via JavaScript code, like this:

fd.rendered(function(){
    //can access the control using its Name:
    fd.control('Button1').text = 'Press me!';
 });

Text

Allows you to type in or copy in the exact text the button will display on the form:

Text property

Type

Allows you to select a type of a button from available types in Bootstrap buttons:

Type property

The color and the appearance of the button will change depending on its type.

Click

Add JavaScript to execute when the button is clicked. With this property empty, the button won’t do anything.

Click code

Width

You can specify the Width of the button in pixels:

Width property

If left empty, the button will take only as much space as necessary for the text, though you can adjust it in Grid Cell properties:

Alignment and Grid Width property

Class

Add a CSS class to the control, which comes in handy with CSS or even JavaScript code. This will work as a class attribute for an HTML tag.

Control's class

The same class can be applied to multiple fields and controls, and then you can use CSS to modify the appearance of these. For example, here we’ve used the following CSS code in the CSS editor to give controls with my-class a rounded appearance:

.my-class {
    border-radius: 12px!important;
}

box-shadow: 0 9px #999;

JavaScript

If you are not familiar with the JavaScript framework, get started with the JavaScript basics.

Note

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

fd.rendered(function(){
    //hide the control
    $(fd.control('Control1').$el).hide();
    //show the control
    $(fd.control('Control1').$el).show();
});

Get or set text

Get or set the text of the button with the following property:

//return the text as a string
fd.field('Control1').text;

//set the text
fd.control('Control1').text = 'New text for the button';

Get HTML element

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

//access control's HTML
var htmlControl = fd.control('Control1').$el;

Get or set script that runs on click

Property that holds JavaScript that is executed when the button is clicked:

//get the script that runs on click
fd.control('Control1').onclick;

//set the script that runs on click
fd.control('Control1').onclick = 'alert("Button is clicked!")';

//trigger the code to run with JavaScript
fd.control('Control1').click();
