[jQuery] How to pass parameter to the "close" event handler of the jQuery.ui.dialog?

[mctpursuer]

The following codes won't work. If you call rPrompt twice with
different index value, the second index value won't be passed to the
"close" event handler. I can work around this issue by using a global
var like gIndex to store the index value, but I would like to know if
there is a more elegent solution. Thanks.

function rPrompt(index, msg)
{
        alert(index);

        if($("#prompt").length == 0){
                $("<div id='prompt'><label></label><textarea rows='5' 
cols='30'></
textarea></div>").appendTo("body");
                $("#prompt").dialog({
                        title: "Test",
                        modal: true,
                        bgiframe: true,
                        overlay: {
                                backgroundColor: '#000',
                                opacity: 0.3
                        },
                        buttons: {
                                'Cancel': function(){
                                        $(this).dialog("close");
                                },
                                'OK': function(){
                                        $(this).dialog("close");
                                }
                        },
                        close: function(){

                                alert(index);
                        }
                });
        }else{
                $("#prompt").dialog("open");
        }
        $("#prompt label").html(msg);
}
