    {
        list:[
            {id: 118, name: "测试1", group_id: 4, os: 2}
            {id: 120, name: "测试11", group_id: 4, os: 2}
            {id: 123, name: "测试111", group_id: 4, os: 1}
        ]
        name: "测试1111"
    },
    {
        list:[
            {id: 118, name: "测试2", group_id: 4, os: 2}
            {id: 120, name: "测试22", group_id: 4, os: 2}
            {id: 123, name: "测试222", group_id: 4, os: 1}
        ]
        name: "测试2222"
    },
]

            {value: 120, name: "测试22", group_value: 4, os: 2}
            {value: 123, name: "测试222", group_value: 4, os: 1}
        ]
        name: "测试2222"
    },
]

var productArr = JSON.parse(JSON.stringify(appList).replace(/list/g, 'children'));
productArr = JSON.parse(JSON.stringify(productArr).replace(/id/g, 'value'));
