what is difference between ajax() and web2py_component() ?

[Ariya Owam-aram]

Hi everyone,

I often use ajax and web2py_component for onclick action (for example) but I never know what is difference between them and how to use them the right way.  Can anyone guide me a good example, please?

Thank your

Ariya

The ajax() function provides basic functionality for making an Ajax request, with some additional features, such as automatically sending values from named input fields and inserting the returned data into a particular target within the DOM (or optionally executing some returned Javascript code).

web2py_component (which is a backward compatible alias for $.web2py.component) is a more sophisticated facility for embedding the output of controller actions within web pages. It is much like a page within a page, with the ability to load new content into the component. In particular, it is possible to trap both links and forms, so when you click a link or submit a form contained within a component, the new content will be loaded within the component (without reloading the rest of the page). Components also include functionality to automatically refresh themselves at a fixed interval.

You would generally use the LOAD helper -- see http://web2py.com/books/default/chapter/29/12/components-and-plugins#Components--LOAD-and-Ajax.

From Javascript, you can also do:

$.web2py.component("{{=URL('mycontroller', 'mycomponent.load')}}", "target_div");

Which will load the component in an existing div whose id is "target_div".

Hi Anthony,

Thank you for your clear and helpful explanation. I still have a question, what is .load is for? Why do I need to specific view extension to .load?  Sometime I use .html for LOAD() or web2py_component() but did't see the difference.

Thank you again

.load is just a convention to help distinguish from a full HTML page, but you can use any extension you want. In some cases, the same controller might be used as both a component and a full web page, so you could have separate .load and .html views for that controller.
