Question

{"some_id":
    [
    {"city":"Bellevue"},
    {"state":"Washington"}
    ]
}

Answer 1

var theJSonString = '({"some_id": [ {"city":"Bellevue"}, {"state":"Washington"} ] })';
var x = eval(theJSonString);
alert(x.some_id[0].city); // will display "Bellevue"

Answer 2

var json = {"some_id": [ {"city":"Bellevue"}, {"state":"Washington"} ] }

json.some_id[0].city等于“Bellevue”

和

json.some_id[1].state等于“华盛顿”

Answer 3

this (the json parser and stringifier from json.org)可能会有所帮助:)（请查看页面底部的链接）

Answer 4

目前所有浏览器都支持window.JSON.parse()。它需要一个JSON格式的字符串并返回一个Javascript对象或数组。

演示：http://jsfiddle.net/ThinkingStiff/KnbAJ/

脚本：

var json = '{"some_id":[{"city":"Bellevue"},{"state":"Washington"}]}'
    object = window.JSON.parse( json );

document.getElementById( 'length' ).textContent = object.some_id.length;
document.getElementById( 'city' ).textContent = object.some_id[0].city;
document.getElementById( 'state' ).textContent = object.some_id[1].state;

HTML：

length: <span id="length"></span><br />
some_id[0].city: <span id="city"></span><br />
some_id[1].state: <span id="state"></span><br />

输出：

length: 2
some_id[0].city: Bellevue
some_id[1].state: Washington

我怎么读这样的JSON结构？
