JSON:JavaScript对象表示法(JavaScript Object Notation)
JSON是存储和交换文本信息的语法。类似XML

JSON比XML更小、更快，更容易解释

<html>      <head>          <title></title>          <meta name="lucheng" content="text/html;charset=UTF-8"/>      </head>      <body>          <script>              function iterateGoodsArr(goodsArr) {                  for(var n=0;n<goodsArr.length;n++) {                      var goods = goodsArr[n];                      document.write(goods.name +"----"+ goods.price  + "<br/>");                  }              }                            /*JSON对象(JSON 数据交换的一种格式)的创建*/              var goodsArr1 = [                  {"name" : "画板","price":100},{"name" : "滑板","price":200}              ];              iterateGoodsArr(goodsArr1);                            /*JSON格式的字符串*/              var goodsArrStr = '[{"name" : "画笔","price":20},{"name" : "杯子","price":20}]';              /*JSON字符串转成JSON对象*/              var goodsArr2 = JSON.parse(goodsArrStr);              iterateGoodsArr(goodsArr2);          </script>      </body>  </html>
