javascript - 使用javascript，如何转换为JSON、类似Java-POJO的类？

Question

我想在我的 JS 项目中使用类似 Java-POJO 的类:仅私有(private)字段、getter 和 setter。

function Event() {
var homeTeam;
var awayTeam;
var id;
var singleBets = [];
var bet;

...

this.getHomeTeam = function(){
    return homeTeam;
}
this.setHomeTeam = function(data){
    homeTeam = data;
}

this.getAwayTeam = function(){
    return awayTeam;
}
this.setAwayTeam = function(data){
    awayTeam = data;
}

this.getId = function(){
    return id;
}
this.setId = function(data){
    id = data;
}

this.getSingleBets = function(){
    return singleBets;
}
this.setSingleBets = function(data){
    singleBets = data;
}

this.getBet = function(){
    return bet;
}
this.setBet = function(data){
    bet = data;
}

}

我会将类似 Java-POJO 的类转换为 JSON 字符串，以将其发送到服务器。我无法使用 JSON.stringify(myClass) 因为这些字段是私有(private)的。所以我想使用像这样的递归方法......

var myJsonParse = function(data){
    var result = "";
    for(var propertyName in data) {
        var method = propertyName;
        if (method.substring(0,3)=="get"){
            ... data[propertyName].call() ...
        }
    }
    return result;
}

...但在我花很多时间写它之前，我想问你是否存在更好的方法来将 Java-POJO 类对象转换为 JSON。谢谢。

我为自己感到羞耻!这是我的工作(但绝对是临时的)解决方案:

this.toJSON = function() {
    var bettableEventsString =  [];
    for (var i = 0, len = bettableEvents.length; i < len; i++) {
        bettableEventsString[i] = bettableEvents[i].toJSON();
    }
    var result = JSON.stringify({
        userId: userId,
        championshipDayId: championshipDayId,
        championshipDayName: championshipDayName
    });

    result = result.substring(0, result.length-1);
    result += ',\n  "bettableEvents" : [ ' + bettableEventsString + " ] ";
    result += " } "

    return result;
}

我能想到的唯一简单的方法是添加导出方法:

this.toJSON = function() {
    return JSON.stringify({
        homeTeam: homeTeam,
        awayTeam: awayTeam,
        id: id,
        // etc...
    });
}
