Working with UnitList

Working with Unit Values

UnitList API makes it possible to get text values of unit headers (unit values) as well as get data items that comply with this or that unit criterion.

  • getUnits() - returns JS array of unit values defined by the uniteBy property. The values are arranged in the alphabetical order, numbers first;
  • getUnitList(id) - returns the ID (or, more often, IDs) of data records united by "unit" criterion.
var units = $$('list').getUnits(); // -> // -> [1, C, M, T]
var unit = $$('unit').getInputNode().value; //getting value of the combo box text field
var id = $$("list").getUnitList(unit);

If you know the ID of any data item, you can easily get to all its properties:

var title = $$("list").getItem(id).title;

If there are several data items that comply to the unit value criterion, they are returned in a JS array, and should be treated accordingly.

Common Functionality:

Note that there's no built-in possibility to edit data with UnitList. You should create a prototype editlist object beforehand.
