How to Extend $.get Function to Call failHandler on Request Failure

How can you extend the $.get function to call the failHandler when the request fails?

To extend the $.get function to call the failHandler when the request fails, how can you achieve this using jQuery?

Answer:

To extend the $.get function to call the failHandler when the request fails, you can use the .fail() method provided by jQuery. Here's an example of how to modify the code:

When working with the $.get function in jQuery, it is essential to handle request failures gracefully. One way to achieve this is by extending the $.get function to call a failHandler function when the request fails. This can be done using the .fail() method provided by jQuery.

By chaining the .fail() method after the .done() method in the $.get function, you can specify a failHandler function to be called in case the request encounters an issue, such as an internet connection problem. This helps in providing feedback to the user and handling error scenarios effectively.

Here is an example code snippet showing how to extend the $.get function to call a failHandler function:

    function requestHandler() {
        console.log("Internet connection issue. Please try again.");
    }

    $.get("https://wp.zybooks.com/fakeur1.php", { "zip": "98210" })
        .done(function(data) {
            console.log("Data handled");
        })
        .fail(requestHandler);
    

In the code snippet above, the .fail() method is used to specify the requestHandler function to be called if the $.get request fails. This ensures that appropriate feedback is provided to the user in case of any issues with the request, such as network problems.

By utilizing the .fail() method in conjunction with the $.get function, you can enhance the robustness of your code and improve the overall user experience by handling request failures effectively.
