Manipulate data destination using Javascript

I have a task in my AngularJS application that involves the following steps:

1) Click on a button.
2) If variableA is true, display a modal.
3) If variableA is false, redirect to another link without showing a modal.

Here is the code I am using to achieve this:

HTML:

<span id="id1" ng-click="getClickType($event,row)" href=""> Text </span>

JS:

$scope.getClickType = function(event,row){
    $scope.activeElement = event.target;
    if(row.type == "A"){
        $scope.activeElement.dataset.target = "#ModalA";
        $scope.activeElement.dataset.toggle = "modal";
        /* No hack needed, modal pops up automatically */
    }
    else{
        someFunction().then(someOtherFunction);
    }
}

someOtherFunction(msg){
    if (msg.varA == true){
        var f1 = $scope.activeElement.dataset.target; //hack
        $scope.activeElement.dataset.target = "#ModalB";
        $scope.activeElement.dataset.toggle = "modal";
        if( f1 != $scope.activeElement.dataset.target){ //hack If statement
           $timeout(function () {
                            $scope.activeElement.click();
                       });
           /* Hack needed to click on the element again to show the modal */
        }
    }
    else{
        $scope.activeElement.dataset.target = "";
        $scope.activeElement.dataset.toggle = "";
        window.open(someURL);
        /* Works fine without needing to click again */
    }
}

As you can see, I am using a workaround for ModalB. Changing the dataset.target in someOtherFunction() doesn't show the modal, requiring a click on the active element again.

My question is:
Why do I have to click on the activeElement again to change the data target.
Why is this only necessary in the second function.

Any insights would be greatly appreciated.

Thank you in advance.

Answer №1

What exactly is happening within someFunction? Is it similar to an AngularJS promise like $q or $http? Have you attempted to execute modalB operations within the $scope.$apply function?

There's a helpful tip for when you accidentally step out of the Angular scope or when you're running non-Angular scripts.

$scope.$apply(function() {
    $scope.activeElement.dataset.target = "#ModalB";
    $scope.activeElement.dataset.toggle = "modal";
 }

Alternatively, you can call $scope.$apply right after opening ModalB

$scope.activeElement.dataset.target = "#ModalB";
$scope.activeElement.dataset.toggle = "modal";
$scope.$apply()

This will prompt Angular to carry out a digest and perform necessary checks. However, there's a caveat to this - if you are already within an Angular context and a digest loop is already in progress, an error will be thrown indicating that the process is already underway and the actual error lies elsewhere.
