array: [
    {
    tags: "沙发",
    count: "2"
    },
    {
    tags: "椅子",
    count: "5"
    },
    {
    tags: "床单",
    count: "1"
    },
    {
    tags: "床垫",
    count: "1"
    },
    {
    tags: "衣柜",
    count: "1"
    },
    {
    tags: "大闸蟹",
    count: "6"
    }
]

this.array.splice(index,1)
