Question

我需要使用JAVA脚本生成一个JSON文件，但是没有得到预期的输出，你能不能帮助我生成这个。

预期结果：

{
    "ewh5yuwe": {
        "NumCopies": "1",
        "NumPages": "10",
        "Status": "done printing",
        "Title": "demo.jpg",
        "Username": "keshavka",
        "date": "23:06 Feb 5, 15",
        "print status": "OK",
        "time": "1429036296",
        "timestamp done printing": "${__time(yyyyMMddHMS)"
    }
}

调用print();函数后收到的

输出如下：

""rYajbQx":{[object Object]}"

代码：

function makeid() {
    var text = "";
    var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

    for (var i = 0; i < 7; i++)
        text += possible.charAt(Math.floor(Math.random() * possible.length));

    return text;
}
//above Code is to generate a Random variable

function test() {
    var jobid = Math.random();
    var jobkey = jobid;
    var time = new Date().getTime()
    var kes = makeid()
    var joblog = {
        "NumCopies": "1",
        "Status": "done printing",
        "Title": "demo.jpg",
        "Username": "keshavka",
        "date": "23:06 Feb 5, 15",
        "print status": "OK",
        "time": "1429036296",
        "timestamp done printing": time
    };

    json = JSON.stringify(joblog);
    console.log(joblog);
    return joblog;
}

// Above code is to generate JSON

var x = test();
console.log(x);
var y = makeid();
console.log(y);


function print() {
    a = ('{' + (test()) + '}');
    return a;
}

好的，我想我知道你想要什么。您希望返回一个具有属性的对象，其中包含您生成的id的名称，并将其值设置为上面代码中列出的属性。我要改变的主要是如何创建对象。因此，在您的测试函数中，我将进行以下更改：

var joblog = {};
joblog[kes] = {    
   "NumCopies":"1",
   "Status": "done printing",
   "Title": "demo.jpg",
   "Username": "keshavka",
   "date": "23:06 Feb 5, 15",
   "print status": "OK",
   "time": "1429036296",
   "timestamp done printing": time 
};

因此，如果您生成了＆＃39; 5YhDv7n＆＃39;的ID，您将获得一个类型为的对象：

{
  5YhDv7n:{
      ObjectNumCopies: "1",
      Status: "done printing",
      Title: "demo.jpg",
      Username: "keshavka",
      date: "23:06 Feb 5, 15",
      print status: "OK",
      time: "1429036296",
      timestamp done printing: 1435580266234
   }
}

我编辑了我JSFiddle以反映这些变化。

问题是你没有返回JSON，而是返回对象本身。

function test() {
    [...]

    var json = JSON.stringify(joblog);
    console.log(json);
    return json;
}

使用JavaScript生成所需文件
