[jQuery] jQuery 1.1 API improvements (macros, events)
Hi folks,
the discussion so far led to the conclusion to remove all those macros
for css() and attr(), eg. color() or val(). css() and attr() are already
quite flexible: Both allow you to get a single property, set a single
property or set a set of properties. I wonder if it would help to extend
them to allow getting of multiple properties at once. A possible
implementation would accept an array of String and returns a key/value
object, with the values of the array as the keys. Is this useful?
Another interesting point that needs some discussion:
The event system is improved by accepting:
- an amount paramter (the number of times to execute an event handler,
default is infinite) and additional data when binding events
- an bubble paramter (to trigger handlers of parent elements) and
additional data when triggering events programmatically
The big so far unsolved question: What should the API methods look like?
How to pass the additional data to the event handler?
Currently I favor an interface that looks like this:
$().bind("type of event", eventHandler, {amount: 5, data: additionalStuff})
$().trigger("type of event", {bubble: true, data: moreStuff});
This avoids any type checking of arguments and provides a clear API: A
little bit more to type, yet less confusion when you need only one of
the optional paramters.
Possible interfaces for the event handlers:
$().bind("click", function(event, bindData, triggerData) { ... });
$().bind("click", function(event) {
event.bind // contains bind data
event.trigger // contains trigger data
});
Your opinions?
