When working with AngularJS, I encounter an error when trying to use querySelector.
angular.element(angular.element(e).querySelector('.open')).removeClass('open');
However, if I switch to using:
angular.element(angular.element(e).find('.open')).removeClass('open');
The code works perfectly fine without any issues.
The specific error message that is thrown:
TypeError: angular.element(...).querySelector is not a function
querySelector is actually a native JavaScript method and not specific to Angular. It is a function provided by the DOM API that can be used on any DOM element.
Therefore, to achieve the same outcome in your code, you can make the following modification:
angular.element(angular.element(e)[0].querySelector('.open')).removeClass('open');
querySelector belongs to the DOM Element, not angular.element (jqLite).
When using querySelector with a jqLite instance, you must first obtain the raw HTMLElement:
angular.element(angular.element(e)[0].querySelector('.open')).removeClass('open');
angular.element(e) is an angular.element instance, which acts like an array of HTMLElements. To access individual elements, you must specify their index, hence angular.element(e)[0].
