咦那不就是object么,

var obj={name:'zhangsan',id:'00123456',sex:'m',age:30}
Copy after login

应该是JSON吧?JSON有两种格式,一种是对象的表示法,另一种是数组的表示法。楼主说的是数组,应该就是JSON的数组表示法了,格式如下:

<code>var arr = [
    {
        name:"zhangsan",
        id:"00123456",
        sex:"m",
        age: 30
    }
]</code>
Copy after login

js里的数组下标只能是数字,所以想要实现类似功能就用object吧。
