从本地嵌套的JSON对象检索数据

[英]Retrieve data from a local nested JSON objects

I made a little test page which looks something like this: 我做了一个小的测试页面,看起来像这样:

<!DOCTYPE html>
<html lang="en" class="no-js">
<head>
    <title>Get JSON Value</title>

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>

</head>
<body>

    <script>

        var json = $.getJSON("../js/report.json", function(data) 
        {
            var items = [];

            $.each(data, function (key, value)
            {
                items.push(key + " " + value);  
            });

            alert(items[3]);
        });

    </script>

</body>
</html>

It fetches the data from a local JSON file stored on my local server. 它从本地服务器上存储的本地JSON文件中提取数据。

The JSON object looks something like this: JSON对象如下所示:

{
  "reportTitle": "Results",
  "inlineAssets": false,
  "stats": {
    "suites": 7,
    "tests": 13,
    "passes": 11,
    "pending": 0,
    "failures": 2,
    "start": "2016-08-11T13:30:48.362Z",
    "end": "2016-08-11T13:31:29.433Z",
    "duration": 41071,
    ...
}

alert(items[2]); gives me stats [object Object] alert(items[3]); 给我stats [object Object] alert(items[3]); gives me suites [object Object] 给我suites [object Object]

Is it possible for me to retrieve the number of suites , tests and passes ? 我可以检索suitestestspasses吗? So the output of the alert would be suites 7 , tests 13 and passes 11 . 因此,警报的输出将为suites 7tests 13passes 11

EDIT: 编辑:

Ideally I'd like to store these values in variables of their own instead of just alert or console.log . 理想情况下,我想将这些值存储在它们自己的变量中,而不是仅将alertconsole.log

EDIT 3: 编辑3:

I've tried: 我试过了:

console.log(items[2].suites); => undefined => undefined

You did not push stats to items array. 您没有将统计信息推送到项目数组。 Thats why you can`t got it data. 这就是为什么您无法获取数据的原因。 Try to do it simpler 尝试使其更简单

var json = $.getJSON("../js/report.json", function(data) {
    var stats = data.stats;
    $.each(stats, function(key, val){
       alert(key + " " + val)
    });
});

Simulation example 模拟实例

Here is a way to retrieve number of suites , tests , passes . 这是一种检索suitestestspasses

Retrieving number of suites => items[3].stats.suites 检索suites数量=> items[3].stats.suites

Retrieving number of tests => items[3].stats.tests 检索tests数=> items[3].stats.tests

Retrieving number of passes => items[3].stats.passes 检索passes => items[3].stats.passes

Replace 3 inside the brackets with whatever index number you want. 将括号内的3替换为所需的索引号。


EDIT 编辑

You can forget my answer above. 您可以忘记我上面的答案。 This is the real answer. 这是真正的答案。 I have modified your code a bit to get your desired answer. 我对您的代码做了一些修改,以获得所需的答案。

var items=[];
function recursive(data){
    $.each(data, function (key, value)
    {
        if (value instanceof Object) {
            recursive(value);
        } else {
            items.push(key + " " + value);
        }
    });
}

var json = $.getJSON("report.json", function(data) 
{
    recursive(data);
    console.log(items[2]); // return 'suites 7'
    console.log(items[3]); // return 'tests 13'
    console.log(items[4]); // return 'passes 11'
});

Since there is an object inside an object, I have to use recursive to trace all the data. 由于对象内部有一个对象,因此我必须使用递归来跟踪所有数据。
