How to access the jQuery event object in a Seaside

2019-06-16 17:32发布

问题:

Basically, I want to translate the following into Seaside Smalltalk:

$(".myDiv").bind('click', function(e) {
    console.log(e);
}); 

Besides that I don't want to console.log the event, but access it in my ajax callback.

The most promising approach seemed to be something like

html div
    onClick: (html jQuery ajax callback: [:v | self halt] value: (???);
    with: 'Foo'.

But I couldn't find any way to access the event that caused the callback. Intuitively, I would try

html jQuery this event

for the ??? part, but the Seaside jQuery wrapper doesn't know any message that comes close to event.

Any help is appreciated. There has to be away to access the event data...

回答1:

To serialize the x mouse coordinate of the event use the following code:

html div
    onClick: (html jQuery ajax
        callback: [ :x | x inspect ]
        value: JQEvent new pageX);
    with: 'Click'.

There are other properties in the event object that you might be interested in, just serialize them with the same AJAX request by adding multiple callback:value: constructs in a cascade.

In the very latest JQuery code you can use html jQuery event to create the event object. This was missing up to now.
