Showing Console Errors And Alerts In A Div Inside The Page

When you're developing a website or a web application, it’s essential to be able to see any errors or alerts that happen in the console. However, sometimes it would be more convenient to display these messages directly on the page itself, making it easier to spot issues or debug problems. In this article, we'll show you how to display console errors and alerts in a

inside your web page.

To achieve this functionality, we can use JavaScript to capture the console messages and then inject them into a

element on the page. This way, you can keep track of any errors or alerts that occur during the execution of your code without having to constantly switch back and forth between the console and the page.

Let's dive into the code!

First, we need to create a

element in our HTML file where we want the console errors and alerts to be displayed. You can place this

anywhere on your page, but for simplicity, let's add it at the bottom:

Html

<div id="error-container"></div>

Next, we'll write a JavaScript function that listens for console errors and alerts and then appends them to the

element we created. Here's the code for that:

Javascript

(function() {
    var oldError = console.error;
    console.error = function(message) {
        oldError.apply(console, arguments);
        document.getElementById('error-container').innerHTML += '<p style="color: red">Error: ' + message + '</p>';
    };
    
    var oldAlert = window.alert;
    window.alert = function(message) {
        oldAlert.apply(window, arguments);
        document.getElementById('error-container').innerHTML += '<p style="color: blue">Alert: ' + message + '</p>';
    };
})();

In this script, we're overriding the default console.error and window.alert functions with our custom functions. These custom functions not only log the messages to the console but also append them as

elements to the

with the id 'error-container'. We apply different styles (red for errors and blue for alerts) to differentiate between the two types of messages.

Now, when an error occurs, it will be displayed in red inside the

element, and when an alert is triggered, it will appear in blue. This makes it easy to spot and address any issues that arise in your code without having to leave the page.

That's it! With this simple trick, you can now display console errors and alerts directly in a

inside your web page, streamlining your debugging process and making it more user-friendly. Happy coding!
