js怎么解析jsonArray里面的数据

科普

[]是数组；{}是对象；

首先判断接受的数据是否是正确的json格式对象

第一种形式   [[ ]]

[["12","32","56","10","67","89","12","12","8","42","33","9"]]

怎么处理上面的数据，处理以后是以下的形式；因为我要在页面上循环遍历

["12","32","56","10","67","89","12","12","8","42","33","9"]

解决方案  eval(数据)

eval(数据)可以对数据进行运算，例如返回数组对象，自动去掉外面多于的[]

  this.tableData=eval(e.data);

第二种形式 {"属性名":"属性值"}

{"sz":["12","32","56","10","67","89","12","12","8","42","33","9"]}

我要获取["12","32","56","10","67","89","12","12","8","42","33","9"]

解决方案

       var obj = eval('(' + e.data + ')');
            alert(obj.sz);
          this.tableData=obj.sz;
