javascript - JSON 重组， 求各位大神。

问题描述

问 题

问题是：怎样把这个json1， 转换成json2 的格式。。。 急死了， 我们前端不好解析0.0

json1:

 var src = {
    "title": "限制标题字数",
    "desc": "",
    "tagInput": "",
    "interest": "1",
    "fwb": "这是富文本11111",
    "goodImg01": "",
    "goodTitle01": "富文本1下面礼物名字1",
    "goodPrice01": "富文本1下面礼物1的价格",
    "goodId01": "富文本1下面礼物1的ID",
    "goodImg02": "",
    "goodTitle02": "富文本1下面礼物2名字2",
    "goodPrice02": "富文本1下面礼物2的价格",
    "goodId02": "富文本1下面礼物2的ID",
    "goodImg03": "",
    "goodTitle03": "富文本1下面礼物3名字",
    "goodPrice03": "富文本1下面礼物3的价格",
    "goodId03": "富文本1下面礼物3的ID",
    "fwb1": "这是富文本2222",
    "goodImg11": "",
    "goodTitle11": "富文本2下面的礼物名字",
    "goodPrice11": "富文本2下面的礼物价格",
    "goodId11": "富文本2下面的礼物ID"
}

JSON2:

     [{
         "fwb": "这是富文本11111",
         "good": [{
                 "goodImg": "",
                 "goodTitle": "富文本1下面礼物名字1",
                 "goodPrice": "富文本1下面礼物1的价格",
                 "goodId": "富文本1下面礼物1的ID"
             },
             {
                 "goodImg": "",
                 "goodTitle": "富文本1下面礼物2名字2",
                 "goodPrice": "富文本1下面礼物2的价格",
                 "goodId": "富文本1下面礼物2的ID"
             },
             {
                 "goodImg": "",
                 "goodTitle": "富文本1下面礼物3名字",
                 "goodPrice": "富文本1下面礼物3的价格",
                 "goodId": "富文本1下面礼物3的ID"
             }
         ]
     },
     {
         "fwb": "这是富文本2222",
         "good": [{
                 "goodImg": "",
                 "goodTitle": "富文本2下面礼物名字1",
                 "goodPrice": "富文本2下面礼物1的价格",
                 "goodId": "富文本2下面礼物1的ID"
             },
             {
                 "goodImg": "",
                 "goodTitle": "富文本2下面礼物2名字2",
                 "goodPrice": "富文本2下面礼物2的价格",
                 "goodId": "富文本2下面礼物2的ID"
             },
             {
                 "goodImg": "",
                 "goodTitle": "富文本2下面礼物3名字",
                 "goodPrice": "富文本2下面礼物3的价格",
                 "goodId": "富文本2下面礼物3的ID"
             }
         ]
     }
 ]

解决方案

var srcStr=JSON.stringify(src);
//加fwb
srcStr=srcStr.replace(/("goodId\d{2}":"[^"]*",)("goodImg\d{2}":)/g,'$1"fwb":"",$2');
//自定义一个符号比如::分隔
srcStr=srcStr.replace(/,("fwb[^"]*")/g,'::"fwb"');
srcStr=srcStr.split('::');

var srcRes=[];
var i=1;
var temp={};
//一项一项取就好了
while(srcStr[i]){
    srcStr[i]=srcStr[i].replace(/,"([a-zA-Z]+)\d{2}"/g,',"$1"');
    srcStr[i]= srcStr[i+1]?('{'+srcStr[i]+'}'):('{'+srcStr[i]);
    temp=JSON.parse(srcStr[i]);
    temp.mark=i;
    srcRes.push(temp);
    i++;
}
console.log(srcRes);
