How to get JSON into JavaScript object array?

Question

I'm stuck with getting the JSON below, generated in Spring Boot, into a JavaScript object array. Could you please help to solve?

I'm using XMLHttpRequest. My JS looks like:

let evtObjt = [];

var request = new XMLHttpRequest(); 

request.onreadystatechange = function () {

   if (request.readyState == 4 && request.status == 200){
      var data = JSON.parse(request.response); 
      console.log(data);

      evtObjt = data; 
   }                
}
request.open('GET', '/rest-view/events', true); 
request.send();

Regards

Does this answer your question? How do I return the response from an asynchronous call? — Taplar

It's convenient for other members if you transcribe your source code into the question instead of posting a picture of it. Please consider the guidelines in asking a question: stackoverflow.com/help/how-to-ask — bad_coder

Hi bad_coder, thank you for your tip but, in this case, I used image for two basic reasons: 1. The image isn't a source code, it's a console print for debugging insight only, as considered in the link you sent me for good/bad practices: "demonstrating rendering bugs, things that are impossible to describe accurately via text." (stackoverflow). 2. The actual source code is in edditable format. Regards — Murilo de Melo Reis

If I understand you correctly you might just need to change your assignment to fix it:

evtObjt = data._embedded.events;

This would assign the events array into the evtObjt. Hopefully that's what you were looking to do.

Hi ORunnals, that makes sense, but I'm getting this error in console : "Uncaught TypeError: Cannot read property 'events' of undefined"
