在javascript中初始化自定义对象数组

Question

I have data coming in from the db I need to store in a js array of objects. How do I initialize this js array of objects , so that I can keep adding the data when I get it from the db .

The object structure will be of this format

var OsNames = [{deviceName:"TV",
releases: [
{release: "rel1", hws : [{hw:"h1"},{hw:"h2"},{hw:"h3"}]},
{release: "rel2", hws: [{hw:"h1"},{hw:"h2"},{hw:"h3"}]}
]},
{deviceName:"Phone",
  releases: [
  {release: "rel1", hws: [{hw:"h1"},{hw:"h2"},{hw:"h3"}]},
  {release: "rel2", hws: [{hw:"h1"},{hw:"h2"},{hw:"h3"}]}]
}];

Answer 1

var OsNames = [];

You can add data to Array by pushing elements in it when you get it from the db

eg

OsNames.push({release: "rel1", hws : [{hw:"h1"},{hw:"h2"},{hw:"h3"});

Answer 2

I think that is what you are looking for.

var osNames = [];
// Get Data from Database
var myData = ajax.get(...);
for (var i=0; i < myData.length; i++) {
    osNames.push(myData[i]);
}
