list: [
    { 
        id: "1",
        name: "暗夜行者-完整版",
        tags: ["3","5","6"]
    },
    { 
        id: "2",
        name: "蹦蹦小开心-高潮版",
        tags: ["2","4"]
    },
    { 
        id: "3",
        name: "蹦蹦小开心",
        tags: ["1","2","4"]
    }
]
type: [
    { 
        id: "1"
        name: "美食"
    },
    { 
        id: "2"
        name: "逛街"
    },
    { 
        id: "3"
        name: "旅行"
    },
    { 
        id: "4"
        name: "萌趣"
    },
    { 
        id: "5"
        name: "时尚"
    },
    { 
        id: "6"
        name: "搞怪"
    },
    { 
        id: "7"
        name: "情感"
    },
    { 
        id: "8"
        name: "夜生活"
    }
]

要求：把list里的tags转换成type对应的name值展示出来

this.list.forEach(item => { 
    item.tags = this.getTag(item.tags) // '旅行，时尚，搞怪' '逛街，萌趣' '美食，逛街，萌趣'
})
getTag(tags) { 
    let str = ""
    this.type.filter(el => { 
        if (tags.indexOf(el.id) !== -1) { 
            str += el.name + ','
        }
    })
    return str.slice(0, -1)
}
