JSON taglib学习笔记

JSON-taglib 是 JSP 2.0 标签库，用于生产 JSON (JavaScript Object Notation) 数据结构。

使用方法:
  把 Json-taglib.jar 到 WEB-INF/lib目录

下面是一个示例：

<json:object>
  <json:property name = " outer "  value = " foo " />
    
  <json:object name = " inner " >
    <json:property name = " innerProp1 "  value = " val1 " />
    <json:property name = " innerProp2 "  value = " val2 " />
    
    <json:object name = " inner2 " >
      <json:property name = " inner2Prop1 "  value = " in2p1 " />
      <json:property name = " inner2Prop2 "  value = " in2p2 " />
    </json:object>  
      
  </json:object> 
</json:object>

输出的内容如下：

{
   " outer " :  " foo " ,
   " inner " : {
     " innerProp1 " :  " val1 " ,
     " innerProp2 " :  " val2 " ,
     " inner2 " : {
       " inner2Prop1 " :  " in2p1 " ,
       " inner2Prop2 " :  " in2p2 "
    }
  }
}

JSON Arrays


使用数组

<json:object> 
  <json:array name = " days "  items = " ${days} " />
  <json:array name = " bools "  items = " ${bools} " />
  <json:array name = " numbers "  items = " ${numbers} " />
</json:object>

输出的结果:

{
   " days " : [ "Mon","Tue","Wed","Thur","Fri","Sat","Sun" ] ,
   " bools " : [ true,false,true ] ,
   " numbers " : [ 1,2,3 ]
}
