I would like to find other data values of json object passed as datasource to igCombo, How can I do that in selectionChanged method?
$(this).igCombo({
dataSource: jsonColumnSchema.Visible,
textKey: "headerText",
valueKey: "key",
autoComplete: true,
selectedItems : [{index: 0}],
enableClearButton : false,
width: "200px",
height:"25px",
selectionChanged: function (evt, ui) { var fieldName = ui.items[0].value;}
});
Thanks lot, this is what I was looking for.
Hi Annasaheb,
To get reference to original dataSource, application may use options.dataSource member, which is set on initialization of igCombo. If dataSource is string (like netflex oData), or if application uses dataSourceUrl, then the best I can suggest, is to use internal member variable _dataSource. That member contains reference to instance of internal $.ig.DataSource object.
Below is example:
$("#combo1").igCombo({ textKey: 'a', valueKey: 'id', selectedItems: [{index: 0}], dataSource: [ {a: 'one', id: 1, val: 123 }, {a: 'two', id: 3, val: 345 }, {a: 'three', id: 3, val: 678 }], selectionChanged: function (evt, ui) { var item, index, str = 'no selection', ds = ui.owner.options.dataSource, _ds = ui.owner._dataSource, selItems = ui.items, selItem = selItems ? selItems[0] : null, index = selItem ? selItem.index : -1; if (index >= 0) { item = ds ? ds[index] : null; if (!item) { item = _ds.dataView()[index]; } str = 'index: ' + index + ', a: ' + item.a + ', val: ' + item.val; } alert(str); } });
