返回正确的元素ID的问题

Question

I've got three links which serve as sorting headings for a table, each is a member of the "sort" class. I wrote a simple jquery function that gets triggered when any "sort" class link is clicked. There's a switch case that assigns a certain column number (columnNum) to be used with the tablesorter plugin. However, right now I'm getting some weird values returned for the id of the sort classes.

$(".sort").toggle(function() { 
    // the column id's are datecaption, hourscaption, taskcaption
    var column = $(this).attr('id');
    var columnNum;

    switch(column){
        case 'datecaption':
            columnNum = 1;
            break;
        case 'hourscaption':
            columnNum = 2;
            break;
        case 'taskcaption':
            columnNum = 3;
            break;
        default:
            break;
    }

    var sorting = [[columnNum,1]]; 
    $("#task_table").trigger("sorton",[sorting]); 
    return false; 
}, function(){
    var sorting = [[columnNum,0]]; 
    $("#task_table").trigger("sorton",[sorting]); 
    return false;               
});  

If I alert the column variable, I get "aeaoofnhgocdbnbeljkmbjdmhbcokfdb-mousedown"--which doesn't serve the rest of the function well.

Can anyone tell me why this might be happening?

Thanks

Without more code or the HTML it's hard to say. My guess is $(this) isn't what you think it is. Try adding console.log($(this)); (preferably in Firebug) click the result and you will see what $(this) is actually referring to.

Additionally, you could query the DOM for $('#aeaoofnhgocdbnbeljkmbjdmhbcokfdb-mousedown') and see and you should get the element $(this) is referring to.
