Hi Sam,

Tracker and event capture apps are based on AngularJS, which works a little
differently from the standard jQuery way of accessing and modifying form
fields.

The steps below, will give you a general structure to interact with form
fields.

First access the custom form

var myForm = document.querySelector('d2-custom-form'); // in tracker custom
forms are under special tag <d2-custom-form />

Now this form contains all models that are exposed inside custom form. In
Angularjs models are defined as scope.

var $scope = angular.element(myForm).scope();

This gives you all scopes, but you need only those relevant to the custom
form input fields. If it is about data entry - the model is "currentEvent"
but if it is registration it is "selectedTei"

$scope.currentEvent - gives you access to data entry fields
$scope.selectedTei - gives you access to registration fields

To access values per data element or attribute, you just say

$scope.currentEvent[data_element_id] or
$scope.selectedTei[attribute_id]

If you want to change value just do

$scope.$apply(function(){
        $scope.currentEvent[data_element_id]= 'new_value';  // if you want
to change data element value
        $scope.currentEvent[attribute_id]= 'new_value;  // if you want to
change attribute value
});


Hope this gives you some direction. As Alex mentioned, you need to think
the AngularJS way :)

Thank you,
Abyot.
