How to create a dynamic object in a loop?

Basically I want to create one large object of many object in JavaScript. Something like:

var ob开发者_JAVA百科jects = {}
for (x)
objects.x = {name: etc}

Any ideas?

var objects = {};

for (var x = 0; x < 100; x++) {
  objects[x] = {name: etc};
}

An actual implementation

Populate a container object with 100 other objects.

<script>
var container = { }; // main object

// add 100 sub-object values
for(i = 0; i < 100; ++i) {
 container['prop'+i ]  /*property name or key of choice*/
         = { 'a':'something', 
             'b':'somethingelse', 
             'c': 2 * i
           }; 
}

TEST THE Results - iterate and display objects...

for(var p in container) {
 var innerObj = container[p];
 document.write('<div>container.' + p + ':' + innerObj + '</div>');
 // write out properties of inner object
 document.write('<div> .a: ' + innerObj['a'] + '</div>');
 document.write('<div> .b: ' + innerObj['b'] + '</div>');
 document.write('<div> .c: ' + innerObj['c'] + '</div>');
}
</script>

Output is like

container.prop0:[object Object]
.a: something
.b: somethingelse
.c: 0
container.prop1:[object Object]
.a: something
.b: somethingelse
.c: 2
container.prop2:[object Object]
.a: something
.b: somethingelse
.c: 4

etc...

Using object[propertyname] is the same as using object.propertyname and hence we can dynamically create object keys with object[propertyname] format
for eg:

var fruits = ["Apple", "Orange", "Banana","Grapes"];
var colors = ["red", "Orange", "yellow","blue"];
var newObj = {};
for (var i = 0; i < fruits.length; i++) {
  newObj[fruits[i]] = colors[i];
}
console.log(newObj);

Try this

var objects = new Array();
var howmany = 10;

for (var i = 0; i < howmany; i++)
{
    objects[i] = new Object();

}

//On Nested Obj like that
var playersCount = {
    "Players" : {}
}

var exempleCount = 5;

for(i=0; i <= exempleCount;i++){
    var BadID = Math.floor(Math.random() * 10000);
  
        playersCount.Players["Player_"+i] = {
            "id":BadID, 
            "xPos":0, 
            "yPos":0, 
            "zPos":0
        };
    }
  console.log(playersCount);
