Question

您好我无法为来自nodejs Server的以下多维JsonArray数据进行循环。

即使jsonarray的索引值也会在有更多数据进入时动态增加。请帮我实现for循环以动态获取数据。

我从服务器获得的响应是： -

[
    [{
        "id": 3,
        "user_id": 22,
        "coin": "btc",

Answer 1

你可以试试这种方式

JSONArray array = yourJsonArrayFromServer;

for(int i = 0 ; i < array.length(); i++){
    // get current object with: array.getJSONObject(i)
    // do something
}

如果我理解你的问题。

Answer 2

var test = []; //your array  
  for(let key of test){
        if(key instanceof Array) {
            console.log('array'); //detect if its an array then do iteration
            getValues(key);
        }else{
            console.log(key); //value to access, its an object
        }
    }

    function getValues(key){
        for(let val of key){
            console.log(val); //value to access, its an object
        }
    }

Answer 3

这将适用于使用JQuery .each()函数

$.each(json, function (key, data) {
  $.each(data, function (index, data) {
    console.log('index', data)
  }) 
});

json是你的JsonArray数据
