Question

我在想我对javascript了解多少，但我必须承认我什么都不知道。我一直在尝试创建一个自定义对象，但似乎仍然没有。

var currentline=[
        {"NAME":"Battery For Alarm Panel","CODE":"POWER MAX","OWN":"ONM"},
        {"NAME":"Fire Alarm Panel","CODE":"SANA SERVICES","OWN":"ONM"}...
       ]

通过following question的帮助，我可以创建以下对象

   // skipping main loop code for brevity
   detailObj=[];
   loop{
     singleObj = {};
     singleObj[currentline['NAME']] = {};
     singleObj[currentline['NAME']][currentline['CODE']] = {};
     singleObj[currentline['NAME']][currentline['CODE']][currentline['OWN']] = value;
     detailObj.push(singleObj);
   }

并获得以下detailObj

       [
        {"Battery For Alarm Panel":{"POWER MAX":{"ONM":7}}},
        {"Fire Alarm Panel":{"SANA SERVICES":{"ONM":8}}}
       ]

我怎样才能push一个对象变成对象，尽管进入数组并且可以获得跟随对象？

       {
       "Battery For Alarm Panel":{"POWER MAX":{"ONM":7}},
       "Fire Alarm Panel":{"SANA SERVICES":{"ONM":8}}
       }

是否有任何在对象中添加对象的功能？

如果currentline是这样的

var currentline = [{
    "NAME": "Battery For Alarm Panel",
    "CODE": "POWER MAX",
    "OWN": "ONM",
    "VALUE": 7
}, {
    "NAME": "Fire Alarm Panel",
    "CODE": "SANA SERVICES",
    "OWN": "ONM",
    "VALUE": 8
}];

只需更改detailObj一个对象而不是推送，将NAMES值指定为键，就像这样

var detailObj = {};    // An object, not an array
currentline.forEach(function(line) {
    detailObj[line.NAME] = {};
    detailObj[line.NAME][line.CODE] = {};
    detailObj[line.NAME][line.CODE][line.OWN] = line.VALUE;
});
console.log(detailObj);
# { 'Battery For Alarm Panel': { 'POWER MAX': { ONM: 7 } },
#   'Fire Alarm Panel': { 'SANA SERVICES': { ONM: 8 } } }

在现有对象中添加javascript对象
