用循环或if语句从json中取数据示例

首先,例如json数据如下书写: {"head": [ {"text":"广州","id":"广州","pid":"广东省"}, {"text":"郑州","id":"郑州","pid":"河南省"}], } 如上,倘若想将id和pid数据依次取出,就只能用循环,代码如下: var head_id = ""; var head_pid = ""; for (var i = 0; i < data.head.length; i++) { head_id += data.head[i].id + " "; //循环输出json数据 head_pid += data.head[i].p
