Monitor the element's height for any changes and update it accordingly on a separate element

Question

Monitor the element's height for any changes and update it accordingly on a separate element

Is there a way to accomplish the following:

I currently have a navigation bar with the class of "navbar-fixed-top", and I've also added a style of min-height: 50px;

Beneath the navigation bar, I have a content section with a class style of padding-top: 70px;

The issue arises when resizing the window smaller - if the height of the navigation bar increases, the content below it is hidden underneath.

How can I monitor the height of the navigation bar in order to dynamically adjust the style of the content class "padding-top" to a higher value?

I attempted using this solution, but it required me to watch one element for changes and then assign something to another element.

Note: I'm seeking a solution using Angular only, not jQuery

To accomplish this task, we can utilize jqLite which is integrated into Angular.js. Unfortunately, in Angular.js version 1, there isn't a direct method to capture window change events.

I have put together a brief demonstration on jsfiddle to illustrate the clean approach: https://jsfiddle.net/example123.

The essential steps involve using angular.element on the $window object to access jqLite events and monitoring the resize event. When the resize event occurs, you need to invoke $scope.$apply(); to notify Angular of any updates.

By tracking the window width, you can also observe changes in the navigation bar's behavior. If needed, you can substitute the window resize event with another jqLite event and follow the same procedure.

$scope.$watch(function() {
    return $window.innerWidth; // Retrieve the window width value
}, function(newValue) {
    $log.info('Width changed!', newValue);
});

angular.element($window).on('resize', function() {
    $scope.$apply(); // Inform the scope of changes
});
