jQuery.ajax handling continue responses: "success:" vs ".done"?

Dealing with AJAX Response: 🌟"success:" vs ".done"🌟

So you've been working with jQuery and AJAX, and you've stumbled upon two different ways to continue your script after making your AJAX call: "success:" and ".done". 🤔 What's the difference? Can you use them interchangeably? Let's dive in and find out! 🕵️‍♀️

According to the jQuery documentation, here's what we know about each:

1️⃣ "success:"

The "success" option is a function that will be called if the AJAX request succeeds. It gets executed when the request is completed and the server sends back a successful response 📡🎉.

2️⃣ ".done"

On the other hand, ".done" is a method that is part of the "Deferred" object in jQuery. It allows you to attach handlers to be called when the Deferred object is resolved. This means that it will be triggered when the AJAX request completes, regardless of whether it's successful or not. 💪🚀

So, is there a difference between the two? 🤷‍♀️

Yes, there is! While both "success:" and ".done" can be used to handle the response after an AJAX call, their purposes are slightly different:

1️⃣ "success:" focuses specifically on handling successful responses. This is useful when you want to perform certain actions only when the AJAX request succeeds. For example, you might want to display a success message or update specific elements on your page based on the response received.

2️⃣ ".done" is more versatile. It allows you to handle both successful and unsuccessful responses. This means you can perform common tasks that need to be done regardless of the request's outcome. For example, you might want to hide a loading spinner or enable a button after the AJAX call completes, regardless of whether it succeeded or failed.

Okay, I get the difference. But when should I use each one? 🤔

Here's a general guideline to help you decide:

✅ Use "success:" when you only want to handle successful responses and perform actions based on that specific scenario.

✅ Use ".done" when you want to perform tasks that are independent of the request's success or failure. This option is great for handling common actions that need to be done after every AJAX call.

Remember, it's all about choosing the most appropriate tool for your task at hand. Using the right method will make your code more clean, maintainable, and aligned with best practices. 🧹💻

📝 Wrapping Up

To wrap things up, both "success:" and ".done" are ways to handle AJAX responses in jQuery. However, they differ in their focus and purpose. "success:" is for handling successful responses specifically, while ".done" allows you to handle all responses, successful or not.

So, next time you're working with AJAX in jQuery, consider the purpose of your code and choose the appropriate method accordingly. Happy coding! 😄👩‍💻
