提问by mike
Basically I want to create one large object of many object in JavaScript. Something like:
基本上我想在 JavaScript 中创建一个包含多个对象的大对象。就像是：

objects.x = {name: etc}
Any ideas?
有任何想法吗？

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

An actual implementation
一个实际的实现
Populate a container object with 100 other objects.
用 100 个其他对象填充一个容器对象。
<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...
测试结果 - 迭代和显示对象...
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
输出就像
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...
等等...

Try this
尝试这个
var objects = new Array();
var howmany = 10;
for (var i = 0; i < howmany; i++)
{
objects[i] = new Object();
}
