How to set multiple items in a multi selection combobox in javascript

[Tomasz]

Hello.

I have a multiselect combobox with checkeboxes. Let assume that variable "options" has value "Building 1, Building 2". My combobox has items "Building 1", "Building 2", "Building 3". I want to by using JS select and check those two values. This code check Building 1 and Building 2, but only Building 2 is really selected.

function setValuesInCombobox(options) {
    var controler =$find(getClientIdById(cboBuildingControlName));
    controler.set_value(options);
    controler.set_text(options);
    var allChoicesFromCbo = controler.get_items()._array;
    var selectedOptions =  options.split(",");

    for(i = 0; i < selectedOptions.length; i++) {
      var building = selectedOptions[i].trim();
      for(j = 0; j < allChoicesFromCbo.length; j++) {
        var nameOfBuildingInCbo = allChoicesFromCbo[j]._properties._data.value;
        if( nameOfBuildingInCbo == building) {
          allChoicesFromCbo[j]._setChecked(true);
          allChoicesFromCbo[j].select();
        }
      }
    }

Hi Tomasz,

As there are missing resources, we have remove the if statement and the sample works properly - all items all checked. You can check it by the get_checked() method. We are sending you the sample in the attachment. Could you please modify the sample so the issue will be reproduced?
