JS解析json问题

json如下：

{
  "code": "0",
  "data": [
    [
      "1657245600000",
      "0.77"
    ],
    [
      "1657245300000",
      "0.76"
    ],
    [
      "1657245000000",
      "0.76"
    ],
    [
      "1657244700000",
      "0.75"
    ],
    [
      "1657244400000",
      "0.74"
    ],
    [
      "1657244100000",
      "0.75"
    ]
]
}

循环解析出里面数据。
谢谢！

forEach?

let data = {
                "code": "0",
                "data": [
                    [
                        "1657245600000",
                        "0.77"
                    ],
                    [
                        "1657245300000",
                        "0.76"
                    ],
                    [
                        "1657245000000",
                        "0.76"
                    ],
                    [
                        "1657244700000",
                        "0.75"
                    ],
                    [
                        "1657244400000",
                        "0.74"
                    ],
                    [
                        "1657244100000",
                        "0.75"
                    ]
                ]
            }
            data.data.forEach(item=>{
                console.log(item)
            })

你想怎么解析，格式又是怎样

 data = {
                "code": "0",
                "data": [
                    [
                        "1657245600000",
                        "0.77"
                    ],
                    [
                        "1657245300000",
                        "0.76"
                    ],
                    [
                        "1657245000000",
                        "0.76"
                    ],
                    [
                        "1657244700000",
                        "0.75"
                    ],
                    [
                        "1657244400000",
                        "0.74"
                    ],
                    [

            }
            for(let d in data){
                if(typeof(data[d])=='string'){
                    console.log(d,':',data[d]);
                }else{
                    let lst = data[d];
                    for(let l in lst){
                        console.log(d,l,lst[l][0],lst[l][1])
                    }
                }

highcharts显示出来后 提示上的时间不对了。

很标准的数据啊，你直接用JSON就可以进行解析的。
