js中如何根据多级索引数值来获得多级数组的元素?例如下面一个无限级评论数组,如果根据[0,1]找到数组第一级的index为0的数组下的replydata的index为1的元素?并且是引用传值,修改data会影响之前的结果。
let data = [
{
"id": 1,
"pid": 0,
"topicid": "16936077025814910031",
"zannum": 0,
"uid": 1,
"atime": 1693732973,
"words": "你好",
"replynum": 0,
"replydata": []
},
{
"id": 2,
"pid": 0,
"topicid": "16936077025814910031",
"zannum": 0,
"uid": 1,
"atime": 1693732982,
"words": "你好鲜牛奶",
"replynum": 1,
"replydata": [
{
"id": 3,
"pid": 2,
"topicid": "16936077025814910031",
"zannum": 0,
"uid": 1,
"atime": 1693735364,
"words": "你就",
"replynum": 0,
"replydata": []
}
]
}
];
const indexes = [0, 1]; // 例如,获取第一个元素的第二个元素
const result = getValueByIndexArray(data, indexes);
console.log(result)
result.replynum=111;
