Is there a comparable function to JQuery's find() in Angular?

When working with Angular, I am looking to replicate the functionality of jQuery's find() method in order to achieve the following:

var $vCard = $(stanza).find("vCard");
var img = $vCard.find('BINVAL').text();
var type = $vCard.find('TYPE').text();
var img_src = 'data:'+type+';base64,'+img;

Instead of relying on jQuery, I want to accomplish this task without it. However, I am struggling to identify the correct approach for extracting these details from a stanza object that contains a VCard received from the server.

Answer №1

Angular, which is based on Javascript (more specifically Typescript), allows you to drop down to plain JavaScript whenever needed. However, it is worth considering alternative approaches to achieving your end goal without relying on the find() method. Angular discourages direct DOM manipulation and instead promotes the use of controllers and templates for designing dynamic pages without directly accessing the DOM.

In the scenario you provided, storing the values of BINVAL and TYPE in the controller could offer a cleaner solution, allowing for reusability when constructing the image URL.

Additionally, ibenjelloun suggested exploring the ViewChild decorator as an alternative if the previous solution does not meet your needs.
