如何在循环中创建动态对象？

Question

基本上我想在JavaScript中创建一个很多对象的大对象.就像是:

var objects = {}
for (x)
objects.x = {name: etc}

有任何想法吗？

Answer 1

var objects = {};

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

Answer 2

一个实际的实现

使用100个其他对象填充容器对象.

<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
           }; 
}

测试结果 - 迭代并显示对象......

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>

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

等等...

Answer 3

使用object[propertyname]与使用相同object.propertyname，因此我们可以动态创建格式为例如的对象object[propertyname]键
：

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);

Answer 4

尝试这个

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

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

}
