Arranging a stack of IonicModals in a specific order

Question

Arranging a stack of IonicModals in a specific order

If you need help with the $ionicModal service, check out this link: http://ionicframework.com/docs/api/service/$ionicModal/

I've encountered a situation where I find myself opening more than two modals at once.

For example:

First, I open a loginModal
Within that modal, the user clicks on a button "openSignUp()" which opens the SignUpModal

But sometimes, the signup modal appears below the login modal. This means I have to close the login modal first before I can access it.

Is there a way to either: - bring the new modal to the front - or organize the order of the modals?

Here is the solution I came up with to address this issue:

To start, create a CSS style for a specific class name

.custom-modal {
    z-index: 11;
}

Next, update the modal's class name by including custom-modal when initializing it

$ionicModal.fromTemplateUrl('myCustomModal.html', {
    scope: $scope,
    animation: 'slide-in-left'
})
.then(function (modal) {
    modal.el.className = modal.el.className + " custom-modal";
    $scope.myCustomModal = modal;
});

When you open modals, they are added to the DOM. Keep in mind that the first modal you open will be the first one added to the DOM.

Additionally, all modals have the same CSS property z-index:10.

To understand why overlapping occurs, consider this scenario:

Modal1 is opened -> Appended to the <body> tag of the DOM.
Modal2 is opened -> Appended to the <body> tag after Modal1's <div> tag.
Modal3 is opened -> Appended to the <body> tag after Modal2's <div> tag.

Bug condition: If you have a button on Modal3 to open either Modal2 or Modal1

The Modal1 or Modal2 will appear behind Modal3.

WORKAROUND: Adjust the z-index of each modal so that when multiple modals are opened, the last one clicked will always appear on top.

I cannot give you a simple solution as it requires editing the source code. However, I successfully addressed this issue by modifying the Pull Request in the Ionic repository. You can review the changes made there for a resolution. It mainly involves manipulation of the z-index property.

One possible approach is to add and delete the modal from the DOM every time it is opened and closed, ensuring that it is always the most recently added modal.

Below is the code snippet demonstrating this technique:

// Function to open the login modal
$scope.openLoginModal = function() {
    $ionicModal.fromTemplateUrl('templates/login.html', {
        scope: $scope
    }).then(function(loginModal) {
        $scope.loginModal = loginModal;

        // Show the modal once it has loaded completely
        $scope.loginModal.show();
    });
};

// Function to close the login modal
$scope.closeLogin = function() {
    $scope.loginModal.hide();

    // Remove the login modal from the DOM
    $scope.loginModal.remove();
};

If you only want to display one modal at a time, you can achieve this by managing the visibility of the modals. For instance:

function showSignupModal() {
   if ($scope.loginModal.isShown())
      $scope.loginModal.hide();
   $scope.signUpModal.show();
}

On the other hand, if you need to keep the loginModal active in the background for some reason, you can handle it like this:

function showSignupModal() {
   if (!$scope.loginModal.isShown()) {
      $scope.loginModal.show();
      $scope.loginModal.hide();
   }
   $scope.signUpModal.show();
}
