Implement a function for templateURL in AngularJS using Typescript programming language

Here is my current setup:

export class MyComponent implements ng.IComponentOptions {
    public static componentName: string = "myViewer";

    public bindings: any;
    public controller: any;
    public controllerAs: any;
    public templateUrl: string;

    constructor() {
        this.bindings = {
            configName: '@'
        };

        this.controllerAs = "ctrl";
        this.controller = MyController;
        this.templateUrl = 'scripts/components/my-viewer/my-viewer.html';
    }

}

I am looking to dynamically specify the templateURL by adding it to the bindings:

this.bindings = {
                configName: '@',
                templateURL: '=?'
            };

To achieve this, I want to use a function for templateURL similar to what can be seen in )

In a previous version of code written in plain JavaScript, I was able to create something like:

templateUrl: function ($element, $attrs) {
      return '<SomeLogicToChooseTheTemplate>';
    }

My question now is how do I implement a similar solution in the Typescript version?

Answer №1

Solution:

For optimal performance, the templateURL function should be utilized as follows:
this.chooseTemplate = function(element: IAugmentedjQuery, attributes: Iattributes) : string {
    return '<SomeDynamicTemplateSelectionLogic>';
}
