1. The 3.8 code for Fabrik is now available on github, in the 'master' branch. If you are familiar with updating Fabrik from github, we would appreciate it if you could test this code on J! 3.8 for us. Once we have some feedback, we'll build a 3.8 release.

Element Javascript (Advanced)

  • Introduction (top)

    Each element in your form has a JavaScript object attached to it. It provides a common interface for managing the element.

    When element's are duplicated in a repeating group a new instance of the original element object is created for the duplicated element.

    Accessing the element (top)

    Elements are contained within their Form's object's formElements property. In turn you can access the form from Fabrik's global namespace. E.g. to access an element called 'users___name' in form 1:

    For Fabrik 3.0 or earlier:
    Code (Javascript):
    var name = Fabrik.blocks['form_1'].formElements.get('users___name');
    For Fabrik 3.1+
    Code (Javascript):
    var name = Fabrik.getBlock('form_1').elements.get('users___name');
    Note that name is an instance of a 'FbElement' class and is not a direct reference to a DOM node which may have the id of 'users___name'.

    To ensure that the form and element is loaded before calling them you should wrap your code in inside the following method:

    Code (Javascript):

    requirejs(['fab/fabrik'], function () {
      // This is your form's id:
      var formId = 1;
      Fabrik.getBlock('form_' + formId, false, function (block) {
        // Block is a reference to the Fabrik form 1 object.
        var field = block.elements.get('users___name');
        field.addEvent('blur', function () {
          alert('you blurred this element');

    File locations (top)

    • media/com_fabrik/js/element.js - All element javascript objects are children of this 'FbElement' class.
    • media/com_fabrik/js/elementlist.js - All 'list' type elements (dropdown, radio, checkbox, databasejoin) elements inherit from this class, which in turn inherits from element.js.
    Finally each plugin has its own file, which is located in:
    • plugins/fabrik_element/{pluginname}/{pluginname}.js - Contains the element specific logic

    Element Javascript Methods (top)

    Code (Javascript):

    var name = Fabrik.getBlock('form_1').formElements.get('users___name');
    // Get an element's value:
    value = name.get('value');
    // Update the value
    name.update('new value');
    // Update list element values
    // This example will select the suboptions with values of 4 and 5,
    // and deselect all others
    name.update(['4', '5']);
    // or since June 2013
    name.set('new value');
    // Reset to original value
    // Clear values:
    // Get the <div> that surrounds all the element's DOM nodes:
    var container = name.getContainer();
    // Get the error message <div>
    var error = name.getErrorElement();
    // Set the element's error message:
    // className can take: 'fabrikValidating', 'fabrikError' or 'fabrikSuccess'
    name.setErrorMessage('this is the message', className);
    // Add an event
    name.addEvent('blur', function () {
        alert('you blurred this element');
    // Get the repeat group #
    Note that if you are adding an event inside the element's Javascript tab, then you can reference the element object with the variable 'this'
