jQuery UI Sortable Position

Question

How do I track what position an element is when its position in a sortable list changes?

Answer 1

I wasn't quite sure where I would store the start position, so I want to elaborate on David Boikes comment. I found that I could store that variable in the ui.item object itself and retrieve it in the stop function as so:

$( "#sortable" ).sortable({
    start: function(event, ui) {
        ui.item.startPos = ui.item.index();
    },
    stop: function(event, ui) {
        console.log("Start position: " + ui.item.startPos);
        console.log("New position: " + ui.item.index());
    }
});
