JSON数组：

JSON 数组保存在中括号内。

就像在 JavaScript 中, 数组可以包含对象：

"sites":[

{"name":"Runoob", "url":"www.runoob.com"},

{"name":"Google", "url":"www.google.com"},

{"name":"Taobao", "url":"www.taobao.com"}

]

 

JSON字符串转换为JavaScript对象：

var text = '{ "sites" : [' +

'{ "name":"Runoob" , "url":"www.runoob.com" },' +

'{ "name":"Google" , "url":"www.google.com" },' +

'{ "name":"Taobao" , "url":"www.taobao.com" }

]

}';

 

var text = '{ "sites" : [' +

'{ "name":"Runoob" , "url":"www.runoob.com" },' +

'{ "name":"Google" , "url":"www.google.com" },' +

'{ "name":"Taobao" , "url":"www.taobao.com" } ]}';

obj = JSON.parse(text);

document.getElementById("demo").innerHTML = obj.sites[1].name + " " + obj.sites[1].url;
