如何将JSON数组转换为json数据。 [英] How do I convert a JSON array to json data.

问题描述

她是我的代码





我收到这种格式的数据。



{d：[{Vehicle：BMW，Date：30，Jul 2013 09:24 AM，Location：Hauz Khas，Enclave，New Delhi，Delhi，印度，速度：42}，

{车辆：本田CBR，日期：30，2013年7月12日上午12:00，位置：军事道路，西孟加拉邦734013，印度，速度：0}，

{车辆：本田雅阁，日期：2013年7月30日上午11:05，地点：DLF Phase IV，Super Mart 1，Gurgaon，Haryana，India，Speed：71}]}





但我需要这种格式的数据没有数组。



[{车辆：宝马，日期：30，2013年7月09:24 AM，位置：Hauz Khas，Enclave，新德里，德里，印度，速度：42}，

{车辆：本田CBR，日期： 2013年7月30日上午12:00，地点：军事道路，西孟加拉邦734013，印度，速度：0}，

{车辆：本田雅阁 ，日期：2013年7月30日上午11:05，Loca ：DLF第四期，超级市场1，古尔冈，哈里亚纳邦，印度，速度：71}]



我尝试过：



成功：功能（数据）{



var dt = JSON.stringify（数据）;

var newdt = dt.replace（/ \\ / g，）;

alert（newdt）; //这里我得到了这个Json数组，我需要将这种格式改为json

}，

Her is my code


I receive data in this format.

{"d":"[{ "Vehicle": "BMW", "Date": "30, Jul 2013 09:24 AM", "Location": "Hauz Khas, Enclave, New Del Del India", "Speed": 42 },
{ "Vehicle": "Honda CBR", "Date": "30, Jul 2013 12:00 AM", "Location": "Military Road, West Bengal 734013, India", "Speed": 0 },
{ "Vehicle": "Honda Accord", "Date": "30, Jul 2013 11:05 AM", "Location": "DLF Phase IV, Super Mart 1, Gurgaon, Haryana, India", "Speed": 71 }]"}


But I need data in this format without the array.

[{ "Vehicle": "BMW", "Date": "30, Jul 2013 09:24 AM", "Location": "Hauz Khas, Enclave, New Del Del India", "Speed": 42 },
{ "Vehicle": "Honda CBR", "Date": "30, Jul 2013 12:00 AM", "Location": "Military Road, West Bengal 734013, India", "Speed": 0 },
{ "Vehicle": "Honda Accord", "Date": "30, Jul 2013 11:05 AM", "Location": "DLF Phase IV, Super Mart 1, Gurgaon, Haryana, India", "Speed": 71 }]

What I have tried:

success: function (data) {

var dt = JSON.stringify(data);
var newdt = dt.replace(/\\/g, "");
alert(newdt); //Here i get this Json array and I need to chenge this format to json
},

推荐答案

var o = [{ "Vehicle": "BMW", "Date": "30, Jul 2013 09:24 AM", "Location": "Hauz Khas, Enclave, New Delhi, Delhi, India", "Speed": 42 }, 
{ "Vehicle": "Honda CBR", "Date": "30, Jul 2013 12:00 AM", "Location": "Military Road, West Bengal 734013, India", "Speed": 0 },
{ "Vehicle": "Honda Accord", "Date": "30, Jul 2013 11:05 AM", "Location": "DLF Phase IV, Super Mart 1, Gurgaon, Haryana, India", "Speed": 71 }]

。 each（o，function（key，val）{
var Vehicle = ;
var 日期= ;
var 位置= ;
var Speed = ;



Vehicle = o [key] .Vehicle;
Date = o [key] .Date;
Location = o [key] .Location;
Speed = o [key] .Speed;

}）;

.each(o, function (key, val) { var Vehicle = ""; var Date = ""; var Location = ""; var Speed = ""; Vehicle = o[key].Vehicle; Date = o[key].Date; Location = o[key].Location; Speed = o[key].Speed; });

success: function (data) {

var dt = JSON.stringify(data);
var newdt = dt.replace(/\\/g, "");
alert(newdt); //Here i get this Json array and I need to chenge this format to json

Can you try code such as:

var dt1 = JSON.parse(JSON.stringify(data.d)); //Edit: added .d which the is root element of the data
//Iterate over records
for (var i = 0; i < dt1.length; i++) {
   var row = dt1[i];
   var vehicle = row.Vehicle; //or you can get values such as  = row["Vehicle"] 
}

},
