如何從json文件創建jQuery變量？

Question

任何幫助非常感謝。

基本上我使用的是mashape的api，但我對JSON文件有點新手。

我想要做的是爲每個團隊總積分創建一個jQuery變量的負載。

請記住，團隊根據其在表格中的位置更改JSON文件中的位置。

下面是我到目前爲止的jQuery代碼（沒有認證碼）和JSON文件。

$.ajax({ 
url: 'https://heisenbug-premier-league-live-scores-v1.p.mashape.com/api/premierleague/table', 
type: 'GET', 
data: {}, 
dataType: 'json', 
success: function(data) { 
    $(data.records).each(function(index, value) { 



    }); 

    console.dir((data.source)); 
}, 
error: function(err) { alert(err); }, 
beforeSend: function(xhr) { 
xhr.setRequestHeader("X-Mashape-Authorization", 
"Auth Code"); 
} 
}); 

和JSON文件。

要創建一個對象併爲每個團隊添加總點數，您需要創建一個映射（鍵/值），其中鍵是每個團隊的名稱，值是每個團隊的總點數。

我承載您的數據在MyJSON。

下面是檢索從遠程服務器中的數據的功能，並初始化包含的總點數爲每個團隊的對象：

function getData() { 
    // https://api.myjson.com/bins/1c6utx 
    var teamScores = {}; 

    $.get("https://api.myjson.com/bins/1c6utx", function(data, status){ 
    $.each(data.records, function(index, value) { 
     if (!teamScores[value.team]) { 
     teamScores[value.team] = 0; 
     } 

     teamScores[value.team] += value.points; 
    }); 

    console.log(JSON.stringify(teamScores)); 
    }); 
} 

/* Output: 
{"Manchester City":24,"Arsenal":23,"Tottenham":19,"Leicester":19,"Manchester United":19,"West Ham":16,"Liverpool":15,"Norwich":15,"Southampton":14,"Chelsea":14,"West Bromwich Albion":14,"Crystal Palace":14,"Watford":14,"Stoke":13,"Swansea":13,"Everton":13,"Sunderland":11,"Bournemouth":10,"Newcastle United":10,"Aston Villa":3} 
*/
