[jQuery] ajaxForm adding parameters to the success option function

[jQuery] ajaxForm adding parameters to the success option function


Hi
I know that the success function has 2 default parameters but how do I
add a custom parameter?
1 - A user clicks a form (with a ID of TOM) button
2 - The loading function gets called which just adds a class to a div
with the ID of TOM_output.
3 - Then ajax requests comes back with success and I want to remove
the class for the target div
How do I access the the target div from with my loaded function??
function button_click(myform){
var button_output = '#' + myform.id + '_output';
var options = {
target: button_output,
    beforeSubmit: loading,
    success: loaded(responseText, statusText, button_output)
};
$(myform).ajaxForm(options);
return false;
}
function loading(formData, jqForm, options){
    // get form id
    var form_id = jqForm[0].id;
// add loading class (starts a spinning gif)
$(form_id).addClass('spinner');
}
function loaded(responseText, statusText,myform){
// remove loading class (stops the spinning gif)
    $(myform).removeClass('spinner');
}
Any help most appreciated
Cheers
Tom
