externalData

allows defining custom 'move' logic for the component.

Example

var dtable = {
    view:"datatable",
    // datatable config
    drag:true,
    externalData: function (data, id){
        data.rank = data.rank || -1;
        data.title = data.title || data.value;
        return data;
    }
};

The property function takes 3 parameters:

• newdata - (object) the data item to move;
• id - (string) the item id in the source element;
• data - (object) original data of the moved data item.

The function is called when a data item is about to be moved to the target component.

When you drag a data item to another component, it preserves its id, unless the target component contains an item with such an id. Then the item will receive a random id. The changed item is newdata. The second parameter, id, stores the initial id of the item and data stores the initial data object.
