Question

我想使用Javascript从以下api获取“Subscribercount”的具体值：

https://www.googleapis.com/youtube/v3/channels?part=statistics&id=UCJwchuXd_UWNxW-Z1Cg-liw&key=AIzaSyDUzfsMaYjn7dnGXy9ZEtQB_CuHyii4poc

然后我想将它存储在2位变量中，我的意思是，如果数字是3256，我想存储：一个变量32个，一个变量56个。

如果你能提供帮助我会很高兴。

获取api数据，将它们放入变量并运行while循环，使用str.substring()从字符串中删除两个字符并将其写入变量。

示例：在“splitCount”数组中写入所有拆分号码：

var splitCount = []; // This is the array in which we store our split numbers
//Getting api results via jQuery's GET request
$.get("https://www.googleapis.com/youtube/v3/channels?part=statistics&id=UCJwchuXd_UWNxW-Z1Cg-liw&key=AIzaSyDUzfsMaYjn7dnGXy9ZEtQB_CuHyii4poc", function(result) {
    //result is our api answer and contains the recieved data
    //now we put the subscriber count into another variable (count); this is just for clarity
    count = result.items[0].statistics.subscriberCount;
    //While the subscriber count still has characters
    while (count.length) {
        splitCount.push(count.substr(0, 2)); //Push first two characters into the splitCount array from line 1
        count = count.substr(2); //Remove first two characters from the count string
    }       
    console.log(splitCount) //Output our splitCount array
});

使用JQuery。

$(document).ready(function(){
        $.ajax({
            url: "https://www.googleapis.com/youtube/v3/channels?part=statistics&id=UCJwchuXd_UWNxW-Z1Cg-liw&key=AIzaSyDUzfsMaYjn7dnGXy9ZEtQB_CuHyii4poc",
            dataType: "json",
            complete: function(data){
                var response = data.responseJSON;
                var items = response.items;
                var item = items[0];
                var statistics = item.statistics;
                var subscriberCount = statistics.subscriberCount;
                console.log(subscriberCount);

            }
        });
    });

如果需要，您可以将所有变量放在一行。

从API获取特定值并存储在变量内（JavaScript）
