Question

当JSON数据在JSON响应中返回时，我对解析JSON数组感到有点困难。

我知道如何在数组是json响应的子记录时解析数组，但不是唯一的响应。

例如，我知道如何做data.streams.array [0] .item，但是当没有＆＃39; stream＆＃39;部分原因我不知道该怎么做（基本上它直接到数组[0]

我在下面尝试过的示例代码

    $( document ).ready(function() {
console.log( "ready to explore" );
$("#getMessage").click(function(){
$("ul").empty();
$.getJSON("https://api.planningalerts.org.au/applications.js?key=<<KEY>>&postcode=2000", function(json){
  var test2 = JSON.stringify(json);
  alert(test2);
  var test = json.address; 
  alert(test);

示例json resposne我正在尝试解析（记住它直接进入数组）

首先，你不必解析任何东西; jQuery会在将它提供给你的回调之前解析它。（因此，Sub tempo() tps = Now + TimeValue("00:01:00") 'your refresh rate Application.OnTime tps, "message_ctrl" End Sub Sub message_ctrl() Call Module1.test 'your macro Call tempo 'this just relaunch schedule when test() finished End Sub可能不是一个很好的参数名称;可能是json或data或response。）

要访问其数据，您就像其他任何JavaScript数组一样（因为它是什么）。例如，第一个条目是一个具有名为applications的属性的对象，该属性引用具有名为application的属性且值为address的对象。所以：

"\"Harbour Plaza\" Lot 5, 25-29 Dixon Street, Haymarket 2000"

还有第二个条目，其地址为console.log(json[0].application.address); // "Harbour Plaza" Lot 5, 25-29 Dixon Street, Haymarket 2000，所以：

"World Square L 10 680 George St, Sydney 2000"

或loop through the array，例如：

console.log(json[1].application.address); // World Square L 10 680 George St, Sydney 2000

显示

"Harbour Plaza" Lot 5, 25-29 Dixon Street, Haymarket 2000
World Square L 10 680 George St, Sydney 2000

在第一个响应时解析JSON数组
