Suggestions for the AJAH Library

Currently, my application is built on classic ASP.

I am interested in incorporating AJAX-style partial page updates to improve the user experience and avoid unnecessary server roundtrips. My goal is to have a list of rows displayed with the option to add more dynamically, save them, and then refresh the table or continue adding new entries.

While I see the value in using AJAX libraries, I believe that for my specific needs, all the additional features they offer might be unnecessary.

I would love to hear recommendations for AJAH libraries that could help me achieve my desired functionality. Additionally, I welcome opinions on whether focusing solely on AJAH, rather than full-blown AJAX, is a viable approach.

(Since my application already has a template rendering function that can convert database data into "rich HTML", I think the most straightforward path forward would be reusing this function to generate replacement HTML to be injected into the page using innerHTML replace through AJAH.)

Thank you.

Answer №1

Have you heard of AJAH? It's not a commonly known term, but it stands for Asynchronous JavaScript and HTML. While Ajax was originally associated with XML, the modern use of Ajax involves making Javascript calls to the server without needing to refresh the entire page. Data can be returned in various formats like JSON, XML, or HTML.

If you're looking to enhance an existing application, jQuery is a fantastic library to consider. It's lightweight, offers numerous plugins, and is great for handling cross-browser compatibility. With jQuery, you can easily create functions like:

<input id="refresh" type="button" value="Refresh">
...
$("#refresh").click(function() {
  $.ajax({
    url: '/getusers',
    type: "GET",
    timeout: 5000,
    dataType: "html",
    failure: function() {
      alert("An error occurred.");
    },
    success: function(data) {
      $("#userlist").html(data);
    }
  });
});

Answer №2

While I prefer to maintain purism, once AJAX is introduced, it's more efficient for the JavaScript code to handle most of the formatting. For instance, when dealing with tables, utilizing a templating plugin for jQuery would be ideal. These plugins allow you to incorporate a static HTML template on the page, and populate it with data retrieved from AJAX queries.

Alternatively, if server-side formatting is preferred, utilizing the .load() method in jQuery can easily fetch HTML content and insert it into any DOM element.
