How to detect a key modifier during mouse click

Hi guys,
Is there a Seaside way to detect if a key modifier is pressed during a mouse click event?

i.e. with standard jquery I can code something like:

$(#myDiv).click(function (e) {
    if (e.keyCode == 18) {
        alert("ALT was pressed");
    }
     else ...
});

but I can't imagine how to do the same on Smalltalk

html div onClick: ????

Can you help me please?
TIA
Dave

The code from previous email wasn't visible, so I repost the email again:

Dave,

Not sure what exactly is the question. Here is what pops to my mind:

html div
        script: (html jQuery this on: 'click' do: ((JSStream on: 'if(e.keyCode === 18) … ‘) asFunction: #(e)))

Seaside’s Javascript generation feature is focused on generating wrapper code around Seaside-generated JQuery callbacks, etc.. so you can easily tie those together with your Javascript code.
If you’re looking to add (jQuery) ajax callbacks in your JS code, here’s an example:

html div
        script: (html jQuery this on: 'click' do: (((JSStream on: 'e.keyCode === 18') then: (html jQuery ajax callback:[ … ])) asFunction: #(e)))

If you need the keyCode to be transported to the server:

html div
        script: (html jQuery this on: 'click' do: ((html jQuery ajax callback:[:keyCode | ... ] value: ((html javascript alias:'e') access: 'keyCode')) asFunction: #(e)))

And there’s many more possibilities.
In general, I think you need to do as much as possible in hand-written Javascript and use Seaside-Javascript to glue server-side Smalltalk callbacks to your client-side Javascript code.

cheers
Johan

Thanks Johan,
That solves my question.
