Javascript开关语句多个案例返回值

我有一个json对象，我从中获取数据，其中包含值（Cow:'Yes'，Chicken:'NULL'）和（Cow:'Yes'，Chicken:'Yes'）等。我只想显示包含'Yes'的值，然后显示它们的值。目前，我只能返回包含“是”的第一个案例，例如，它只返回“Cow”，但是如果两者都有“Yes”值，则目标是返回“Cow，Chicken”。我做错了什么？或者如果有更好的方法，谢谢你的帮助

switch ("Yes") {
    case popup.properties.Beef:   return "<span>Cows</span>";
    case popup.properties.Pork: return "<span>Pigs</span>";
    case popup.properties.Sheep:  return "<span>Sheep</span>";
    case popup.properties.Goat: return "<span>Goats</span>";
    case popup.properties.Lamb:  return "<span>Lambs</span>";
    case popup.properties.Rabbit: return "<span>Rabbit</span>";
    case popup.properties.OtherMeat:  return "<span>Other</span>";
    case popup.properties.Chicken: return "<span>Chicken</span>";
    case popup.properties.Turkey:  return "<span>Turkey</span>";
    case popup.properties.Duck: return "<span>Duck</span>";
    case popup.properties.Goose:  return "<span>Geese</span>";
    case popup.properties.Pheasant: return "<span>Pheasants</span>";
    case popup.properties.Quail:  return "<span>Quail</span>";
    case popup.properties.OtherPoultry:  return "<span>Other Poultry</span>";
    default:      return "";
}

开关（“是”）{
case popup.properties.Beef：返回“Cows”；
case popup.properties.Pork：返回“Pigs”；
case popup.properties.Sheep：返回“Sheep”；
case popup.properties.Goat：返回“山羊”；
case popup.properties.Lamb：返回“Lambs”；
case popup.properties.Rabbit：返回“Rabbit”；
case popup.properties.OtherMeat：返回“其他”；
case popup.properties.Chicken：返回“Chicken”；
case popup.properties.Turkey：返回“Turkey”；
case popup.properties.Duck：返回“Duck”；
case popup.properties.Goose：返回“Geese”；
case popup.properties.phiasant：返回“phiasants”；
case popup.properties.Quail：返回“Quail”；
case popup.properties.otherfollowing：返回“Other following”；
默认值：返回“”；
}

您可以获取具有所需值的对象，并获取字符串数组

var values = { Beef: "Cows", Pork: "Pigs", Sheep: "Sheep", Goat: "Goats", Lamb: "Lambs", Rabbit: "Rabbit", OtherMeat: "Other", Chicken: "Chicken", Turkey: "Turkey", Duck: "Duck", Goose: "Geese", Pheasant: "Pheasants", Quail: "Quail", OtherPoultry: "Other Poultry" };
    result = Object
        .keys(popup.properties)
        .filter(k => popup.properties[k] === 'Yes')
        .map(k => values[k]);

最好使用数组。filter（）并过滤掉具有“是”函数的动物只能返回一次。最好使用数组。filter（）并过滤掉具有“是”函数的动物只能返回一次。太快了。我只是做了一个类似的回答+太快了。我只是做了一个类似的回答+1.
