A guide on retrieving information from a JSON object using Typescript

When working with values retrieved from an API in JSON format, I encounter a challenge.

While I can view the object's values in the console, I struggle to assign them to individual variables.

Is there a way to separate and assign these values to different variables?

I aim to validate the data before passing it to the HTML for display.

IMG Values in the console

this.http
  .get(this.url + e)
  .map((res) => res.json())
  .subscribe((data) => this.user = data);

OR

getData() {
let e = md5(this.userString);
this.http
  .get(this.url + e)
  .map((res) => res.json())
  .subscribe(
  user => this.user = user,
  error => this.errorMessage = <any>)}

Thank You

Answer №1

Unfortunately, I am unable to leave comments, but it seems like the function is located in the html page. You need to call the function in a specific div and then retrieve the data with the desired information. For instance, in your scenario, it would look something like this:

<div click()= "getData()">
<p *ngFor="let i of data"> {{i.username}}
<p *ngFor="let i of data"> {{i.id}}

If the data were in an array, this setup would function correctly.
This is my interpretation of your question.
