FreeLists / dokuwiki / [dokuwiki] [OFFTOPIC] odd addEvent problem

[Michael Klier <chi@xxxxxxxxxxx>]

Hi folks,

sorry for this totally dokuwiki unrelated post but maybe one of you can
help me.

I am currently working on a calendar plugin for dokuwiki (again...).
This plugin has a toolbar with several buttons (in their own forms) to
switch the calendar view (week/month/year). I like to do this
view-switching thing via ajax. Therefore I call a JS function
addToolEvents() via the addInitEvent() in order to attach an event
to each of these buttons.

addInitEvent(
    function() {
        calendar.attachToolEvents($('plugin_calendar_tools'));
    }
);

the attachToolEvents() function looks like this:

calendar = {

    ...

    attachToolEvents: function(obj) {
        if(!obj) return;

        var argv    = '';
        var button  = '';
        var arg     = [];

        // attach toolbar buttons
        var tool_btns = getElementsByClass('cal_tool_btn',obj,'form');
        if(tool_btns) {
            for(var i=0;i<tool_btns.length;i++) {
                argv   = '';
                button = getElementsByClass('button',tool_btns[i],'input')[0];
                arg    = getElementsByClass('arg',tool_btns[i],'input');
                for(var j=0;j<arg.length;j++) {
                    argv += arg[j].name + '=' + arg[j].value + '&';
                }
                // add calendar namespace to argument list
                argv += 'cal_ns=' + calendar.calNS;
                // attach the Event
                addEvent(button,'click',function() { return 
calendar.show(argv); });
            }
        }
    },

    ...

};

The odd thing is that every Button gets the arguments of the last button
attached, so clicking on any of these buttons results in the same action.
I really don`t know why this is happening. I use a more ore less equal
function in another place and have no problems there :-?. I have
checked so far:
    - that I have no JS Errors in Firefox JS-Console
    - that the objects returned by getElementsByClass() are the right
      ones
    - that argv has the right values for every button

Any feedback on this would be highly appreciated :-).

Thanks in advance.

Michael
