Есть два массива объектов:
var all_labels_list = [{id: "e:1222", text: "1"},
{id: "e:1244", text: "11"},
{id: "e:1237", text: "111"},
{id: "e:1236", text: "1111"},
{id: "e:1223", text: "2"},
{id: "e:1224", text: "3"},
{id: "e:1225", text: "4"},
{id: "e:1226", text: "5"},
{id: "e:1228", text: "6"},
{id: "e:1229", text: "7"},
{id: "e:1249", text: "8"},
{id: "e:1250", text: "9"},
{id: "e:1220", text: "d"},
{id: "e:1219", text: "ds"},
{id: "e:1217", text: "dsd"},
{id: "e:1227", text: "dsddsdds"},
{id: "e:1215", text: "dsdsd"},
{id: "e:1216", text: "dsdsdsd"},
{id: "e:1232", text: "fdfdfdffdfd"},
{id: "e:1230", text: "fff"},
{id: "e:1231", text: "ffff"},
{id: "e:1221", text: "s"},
{id: "e:1218", text: "sd"},
{id: "e:1247", text: "sdsd"},
{id: "e:1243", text: "sdsdsd"},
{id: "e:1233", text: "ss"},
{id: "e:1235", text: "sss"},
{id: "e:1234", text: "ssss"},
{id: "e:1212", text: "\u0412\u0435\u0431\x2D\u0441\u0430\u0439\u0442"},
{id: "e:1242", text: "\u0432\u044B\u0432\u044B\u0432\u044B"},
{id: "e:1248", text: "\u043D\u043E\u04321"},

{id: "e:1246", text: "\u043D\u043E\u0432\u0430\u044F\x20\u043C\u0435\u0442\u043A\u0430\x20\u0438\u0437\x20\u0441\u043A\u0440\u044B\u0442\u043E\u0433\u043E\x20\u0438\u043D\u043F\u0443\u0442\u0430"},];
var selected_labels = [{id: "e:1222", text: "1"},
{id: "e:1244", text: "11"},
{id: "e:1237", text: "111"},
{id: "e:1236", text: "1111"},];
Как их конкатенировать сравнивая по ID (он уникальный), а повторяющемся элементам добавить:
selected = true?
