Selecting elements within a sub directive in AngularJS

I am working with a nested directive setup like this.

<main>
 <app-header></app-header>
 <app-footer></app-footer>
</main>

The app-footer directive contains a small div with a height of approximately 50px.

<div class="footer"></div

My goal is to retrieve the height of the footer within the main directive's link function.

angular.module("app").directive("main", [function () {

    return {
        "restrict": "E",
        "transclude": true,
        "template": "<h1>hello</h1><div ng-transclude></div>",
        "link": link
    };

    function link(scope, element) {

        var footerHeight1 = $(".footer").height() || 0;  // returns 0
        var footerHeight2 = element.find('.footer');  // returns prevObject

    }
}]);

Unfortunately, I have been unable to successfully retrieve the height of the footer.

Answer №1

To determine the margin, padding, and height of the main section based on the footer's height, you can use the following approach (keeping in mind that the footer's height may vary over time):

function updateMainHeight(scope, element) {
    var footer = element.find(".footer");

    scope.$watch(function() {
        return footer.height();
    }, function(footerHeight) {
        // Perform actions on the main section using the footer's height
        // mainHeight = footerHeight
    });

}
