在一维数组或多维数组中找到某个元素的索引

property：为需要查找的字段key

children：为子数组的key

const arr = [
    {
        id: 1,
        name: '一级菜单1',
        children: [
            { id: 2, name: '二级菜单1', children: [] },
            { id: 3, name: '二级菜单2', children: [] },
            { id: 4, name: '二级菜单3', children: [] },
        ]
    },
    {
        id: 5,
        name: '二级菜单1',
        children: [
            { id: 6, name: '二级菜单4', children: [] },
            { id: 7, name: '二级菜单5', children: [] },
            { id: 8, name: '二级菜单6', children: [] },
        ]
    }

console.log(result) // 输出[0,0]
