Get Current Page Http Status From Javascript

Getting the HTTP status of the current web page using JavaScript can be useful for a variety of reasons. Whether you're troubleshooting errors, implementing error handling, or simply wanting to gather data for analytics, knowing how to retrieve the HTTP status can be a handy skill for any developer.

To get the HTTP status of the current page in JavaScript, you can use the `XMLHttpRequest` object. This object allows you to make HTTP requests from a web page and retrieve information about the response, including the HTTP status code. Here's a step-by-step guide on how to achieve this:

1. Create a new instance of the `XMLHttpRequest` object:

var xhr = new XMLHttpRequest();

2. Use the `open` method to specify the type of request and URL of the current page:

xhr.open('GET', window.location.href, true);

3. Set up an event listener to handle the response and extract the HTTP status:

xhr.onreadystatechange = function() {
  if (xhr.readyState === XMLHttpRequest.DONE) {
    var status = xhr.status;
    console.log('HTTP status of the current page: ' + status);
  }
};

4. Send the request:

javascript
xhr.send();
```

5. When you run the above code in your browser's developer console, you should see the HTTP status of the current page printed in the console. The HTTP status code represents the outcome of the HTTP request, such as 200 for a successful request, 404 for a not found error, or 500 for a server error.

It's worth noting that the code snippet above makes an AJAX request to the current page, so keep in mind potential cross-origin restrictions when testing this in different environments.

By utilizing JavaScript to fetch the HTTP status of the current page, you can gain valuable insights into the state of your web application and improve user experience by handling errors more effectively.

In conclusion, being able to retrieve the HTTP status of the current page using JavaScript is a valuable skill for any web developer. By following the steps outlined in this guide, you can easily access this information and use it to enhance your web development projects.

So next time you find yourself needing to check the HTTP status of a web page dynamically, remember this simple JavaScript technique to get the job done efficiently and effectively. Happy coding!
