通过类名称和属性值获取元素并在AngularJS中设置CSS

Question

I have a directive:

class LkfsSliderDirective {

constructor() {
    this.restrict = "E";
    this.templateUrl = "./controls/lkfsSlider/lkfsSliderTemplate.html";
    this.controller = 'LkfsSliderController';
    this.controllerAs = 'slider';
    this.replace = true;
    }

    link(scope, element, attrs) {

    }
}

export default LkfsSliderDirective;

In HTML:

<img ng-src="{{slide.image}}" class="lkfs-slider-slide" alt="" id="{{slide.id}}" ng-repeat="slide in slider.slides"/>

I would like get img tag by class name with specific id (for example = 0) and set CSS ( display: block ).

I tried in many ways but nothing works, for example:

var elem = document.getElementsByTagName("img")[0];
angular.element(elem).css('display', 'block');

Also in link.

Any ideas?

Answer 1

Just select the element with the specific ID using document.getElementById() :

var elem = document.getElementById("0");
angular.element(elem).css('display', 'block');
