Can someone, please, explain to me, why in the code snippet below I get request.response == null? In my JSON file I have an array with some data, which I want to use further.
After spending a lot of time on finding a problem, I found that there is a problem with link. When I uploaded JSON file into web service and used a link from that, it works fine. But when I use a link to the file in my file system, it doesn't want to work.
let requestURL = "../sliderContent.json";
const request = new XMLHttpRequest();
request.open('GET', requestURL);
request.responseType = 'json';
request.send();
request.onload = () => {
if (request.readyState === 4 && request.status === 200) {
let slidesContent = request.response;
console.log(slidesContent);
returnSlidesReducer(slidesContent);
}
};
