Moving an item programmatically with jQuery sortable while still triggering events

Question

I am using jQuery Sortable. I have the HTML setup like so:

  
1
  
2         


        

Answer 1

$("selector").trigger("sortupdate");

you will have to maybe pass in as second argument a function where to put in the event and the ui, event is not as important as ui

the inside code of the sortable widget for event triggering looks like this

this._trigger("update", event, this._uiHash(this));

So you may want to do following

function triggerUpdateFor(selector) {
    var widget = $(selector).sortable("widget");
    if (widget) widget._trigger("update", null, widget._uiHash(widget));
}
