Searching for a nested element within an AngularJS directive

While working on a directive, I am facing an issue with using the element parameter to locate its children by class name.

.directive("ngScrollList", function(){
    return {
        restrict: 'AE',
        link: function($scope, element, attrs, controller) {

            var scrollable = element.find('div.list-scrollable');

            ...
        }
      };
})

Although I can locate it by the tag name, I am unsuccessful in finding it by class name, as evident from the console output:

element.find('div')
[<div class=​"list-viewport">​…​</div>​,<div class=​"list-scrollable">​…​</div>​]
element.find('div.list-scrollable')
[]

What is the correct approach to achieving this? I am aware that I can incorporate jQuery, but I am concerned if that would be excessive....

Answer №1

When using jQlite (angular's version of jQuery), it is important to note that it does not support class lookup.

One workaround is to incorporate jQuery into your application.

Alternatively, you can utilize QuerySelector or QuerySelectorAll:

link: function(scope, element, attrs) {
   console.log(element[0].querySelector('.list-scrollable'))
}

In this code snippet, we access the first item in the element array, which represents the HTML element. Using element.eq(0) would produce the same result.

FIDDLE

Answer №2

When implementing your link function, remember to follow these steps:

// link function
function (scope, element, attrs) {
  var myElement = angular.element(element[0].querySelector('.list-scrollable'));
}

Furthermore, when using your link function, avoid naming your scope variable with a $. The convention of prefixing with a $ is reserved for Angular's built-in services and should not be used for your own variables.
