使用RegExp轉換JSON鍵值

Question

我從服務器調用中收到一個JSON字符串，格式如下：

{"0":{"jpgN":"2","spread_value":"392.22","relevant_new":"text"},"1":{"jpgN":"1","spread_value":"395.28","relevant_new":"text"},"count":2}

使用RegExp，有沒有辦法用字符串"http://mydomain.com/keyValue.jpg" （例如"http://mydomain.com/2.jpg" ）替換任何鍵jpgN的值？

Answer 1

將"jpgN":"([^"]+)" "jpgN":"http://mydomain.com/$1.jpg"為"jpgN":"http://mydomain.com/$1.jpg" 。

但是最好使用您的編程語言解析json並更改值。

Answer 2

那樣的東西？

var json = {"0":{"jpgN":"2","spread_value":"392.22","relevant_new":"text"},"1":{"jpgN":"1","spread_value":"395.28","relevant_new":"text"},"count":2};
var s = JSON.stringify(json);

s.replace(/\"jpgN\":\"(\w+)\"/g, "\"jpgN\":\"http://mydomain.com/$1.jpg\"");
