以上是数据源

javascript 获取jason值

  var jsonData;

$.ajax({
                    type: "Get",   //请求的方法
                    url: "../public/dataaccess/rain/RainAreaMaxDataProvider.ashx?adomParameter=" + Math.floor(Math.random() * 1000 + 1), //要传递参数使用Ajax进行处理的类名称
                    dataType: "text",   //返回的数据类型
                    global: false,  //Ajax的范围
                    async: false,   //异步执行
                    //成功情况下的处理
                    success: function (strReult) {

                       jsonData=eval("("+strReult+")");              
// var f= jsonData.AreaMax.data[0].AREA;
                    }, //失败情况下的处理
                    error: function () {
                        alert("Ajax请求数据失败!");
                    }
             });

            //循环读取

            for(var i=0;i<jsonData.AreaMax.data.length;i++){
                       rainAreaMaxHtml+=jsonData.AreaMax.data[i].AREA+jsonData.AreaMax.data[i].STNM+jsonData.AreaMax.data[i].VAL;
             }
