如何過濾映射字段數(shù)組

我映射了以下項(xiàng)目數(shù)組以獲得結(jié)果

 var items = $.grep($.selections);

其中項(xiàng)目如下：

0: {ID: "310882", Type: "W", Total: 10}
1: {ID: "31094", Type: "W",  Total: 10}
2: {ID: "307969", Type: "W",  Total: 10}
3: {ID: "311951", Type: "W",Total: 10}
4: {ID: "ItemCover_1611315351331", Type: "F", Total: 5, AmountDue:55}

所以我想做的是得到所有我能得到的總數(shù)，如下所示

var AllTotal=items.map(x => x.Total);

這給了我下面的結(jié)果

0: 10
1: 10
2: 10
3: 10
4: 5

我的問題是，你是否注意到數(shù)組中的這個(gè)項(xiàng)

4: {ID: "ItemCover_1611315351331", Type: "F", Total: 5, AmountDue:55}

它有一個(gè)ID：以“ItemCover”開頭，AmountDue為55

當(dāng)我有這樣一個(gè)性質(zhì)的項(xiàng)目，我怎么能過濾出5的總數(shù)，并替換為到期金額，使它現(xiàn)在應(yīng)該像這樣

var AllTotal
   0: 10
    1: 10
    2: 10
    3: 10
    4: 55
