What is the most effective method for adding data from an AJAX call?

Currently, I am utilizing JSON in conjunction with AJAX to dynamically generate all necessary DOM elements. However, I have been contemplating whether this approach is ideal. For instance, when creating a table of data, would it be more efficient to construct it using JavaScript or generate it on the server and then append the result to the page?

UPDATE: My current process involves:

jQuery.getJSON(url, function(result){var table = jQuery('<table/>').append([jQuery('<td/>.....

Alternatively, I could simplify it by doing:

jQuery.get(URL, function(result){jQuery('body').append(result);}.......

Answer №1

It's impossible to give a definitive answer to your query as it largely depends on the type of software you're using and the expected traffic load.

If you were to move "rendering" to the client side, this could potentially reduce the amount of code exchanged between the server and the client, leading to less strain on server resources when generating HTML (although the difference may be minimal). This optimization becomes crucial when dealing with high volumes of online visitors.

However, if your website is attracting thousands of users, chances are you wouldn't be contemplating this question in the first place :) It might be best to handle all formatting on the server side and avoid getting caught up in this dilemma.

Answer №2

The impact greatly varies based on the size of the output. For smaller outputs, the format used may not have much significance.

However, when dealing with a large volume of data to populate a table, opting for a JSON response proves to be more efficient compared to generating HTML code for the table.

Incorporating a template engine, as suggested by @Arun P Johny in the comment, is an effective approach to handle and present JSON results.

There are no absolutes when it comes to choosing the right format for your data. It's all about finding what works best for you. Personally, I prefer using JSON for its versatility. However, one thing you should always avoid is returning data as HTML that needs to be directly appended. Keeping your data separate from any presentation-related structures is key.
