For those budding developers out there looking to get into ajax, here is a short tutorial of an easy way to ease into it.
If you haven't yet looked into a javascript framework such as prototype, now is the time to do so.
Prototype gives a quick and easy way to do some simple ajax calls from your javascripts without doing a lot of work.
For example, if you wanted to submit a variable to a backend page, putting the result of the call into a html element.
[code]
function superButtonClick() {
new Ajax.Updater('id_of_the_element','/backend_page.php', {
method: 'get',
parameters: {the_variable_name: 'the_variable_value'}
});
}
[/code]
That simple snippet when called from a button onClick will fetch the results of url "backend_page.php?the_variable_name=the_variable_value" and place them into a html element with the id "id_of_the_element".
It's really that simple to make an ajax call using the prototype js framework.
