How to use the XMLHttpRequest method in Javascript to retrieve an "href-link" from a JSON file?

edit

To retrieve an "href-link" from a JSON file using the XMLHttpRequest method in JavaScript, you can follow these steps:

1. Create a new XMLHttpRequest object using the "new" operator.

var xhr = new XMLHttpRequest();

1. Specify the URL of the JSON file that contains the "href-link" you want to retrieve using the open() method. This method takes two parameters – the HTTP method (GET, POST, etc.) and the URL of the file.

xhr.open('GET', 'path/to/your/file.json');

1. Set the responseType property of the XMLHttpRequest object to "json". This tells the server that you are expecting JSON data in response.

xhr.responseType = 'json';

1. Set up an event listener using the onload property to handle the response. This function will be called when the server returns a response.

xhr.onload = function() {
   var data = xhr.response;
   var link = data.href;
   // Do something with the retrieved link.
};

1. Send the XMLHttpRequest by calling the send() method. This will initiate the network request and retrieve the JSON data from the server.

xhr.send();

Note: Make sure the server is configured to return valid JSON data. Also, ensure that the JSON file has a valid structure with the "href-link" you want to retrieve.
