XMLHttpRequest is a JavaScript object that allows developers to send HTTP requests from a web page to a server. The GET request is one of the most commonly used HTTP requests, and it is used to retrieve data from a server. In this blog, we will discuss how to send data in a GET request of XMLHttpRequest in JavaScript.

Create an instance of the XMLHttpRequest object

In this example, we create an instance of the XMLHttpRequest object and assign it to the variable xhr.

Build the query string with the data to send

  .map(([key, value]) => `${encodeURIComponent(key)}=${encodeURIComponent(value)}`)

const url = `https://example.com/api?${queryString}`;

In this example, we create a JavaScript object data with two properties, name and age. We then use the Object.entries method to convert the object to an array of key-value pairs, which we map to an array of encoded key-value pairs. Finally, we join the array of encoded key-value pairs with the & symbol to create a query string. We append the query string to the API endpoint URL to create the full URL for the GET request.

In this example, we use the open method of the XMLHttpRequest object to open a GET request with the URL we created in step 2.

In this example, we use the send method of the XMLHttpRequest object to send the GET request to the server.

In this example, we use the onload method of the XMLHttpRequest object to handle the response from the server. We check the status property of the XMLHttpRequest object to ensure that the response was successful, and we log the response text to the console. If the response was not successful, we log an error message to the console.

By following these steps, you can send data in a GET request of XMLHttpRequest in JavaScript. This approach can be used in a variety of applications, such as retrieving data from an API or server, and can be customized to include additional headers, parameters, or data as needed.

Today we will discuss how to send data in a GET request of XMLHttpRequest in JavaScript, developers can create an instance of the XMLHttpRequest object.
