Creating a dynamic Ajax-based widget for your website: A step-by-step guide

I have a unique idea for a web widget that I want to create. This widget will need to be easily integrated into any website using javascript. It will post a form to my server, receive the data, and display the results in a small area of the host website's screen, similar to Google Adsense. I am aware of the security concerns related to XSS and cross-domain issues with ajax.

I need help with mapping out the flow of this widget. Has anyone attempted something similar in the past?

The basic process is as follows:

  1. A website embeds external javascript
  2. The javascript generates a form
  3. The user submits the form with POST data
  4. The POST data is sent to an external server
  5. The server responds and the widget updates to display tabular data

Is this concept feasible? How can it be implemented? Should I consider using or avoiding a JS framework like Prototype or jQuery for this project?

If anyone has any helpful tutorials or resources for building widgets, I would greatly appreciate it.

Any assistance would be highly valued.

Answer №1

One cannot rely on using a library such as jQuery, as it may not be referenced in the website where your widget is used.

However, by utilizing an iframe and displaying content from your own host, it should be possible to use a library if I am not mistaken.
