Question

我有一个JavaScript对象是通过MSQL查询从PHP创建的。

但是，JavaScript对象并不是我需要的。

JavaScript对象：

  var data = [{"name":"Ashley","latitude":"51.46619000","longitude":"-2.58345600","type":"% respondents who go to work (as driver) by car","percentage":"25.3","year":"2013"},{"name":"Ashley","latitude":"51.46619000","longitude":"-2.58345600","type":"% respondents who go to work by walking","percentage":"37.7","year":"2013"},{"name":"Avonmouth","latitude":"51.49275700","longitude":"-2.68259000","type":"% respondents who go to work by train","percentage":"0.0","year":"2013"},{"name":"Avonmouth","latitude":"51.49275700","longitude":"-2.68259000","type":"% respondents who go to work by moped\/motorbike","percentage":"1.2","year":"2013"}...etc];

上面只是一个例子，总共有35个不同的病房＆＃34;名称＆＃34;并且每种类型都有一个单独的，即＃34;％为每个名字开车上班的人（作为司机）＃34;

我需要它为每个名称提供一个对象，并且所有类型和百分比都在子数组中。例如：

var data = [{"name":"Ashley","latitude":"51.46619000","longitude":"-2.58345600”,"types":[{“type”:”% respondents who go to work (as driver) by car”,”percentage”:”25.3”,”year”:”2013”},{"type":"% respondents who go to work by walking","percentage":"37.7","year":"2013”}}...etc]},{"name":"Avonmouth",...etc}];

有没有办法可以在JavaScript中重新构造对象？所以它基本上合并了数据，因此没有重复的名称对象，并且每个名称都将所有类型放入子数组中。

修改

我尝试过stackoverflow的各种解决方案，例如：

var res = {};

$.each(data, function (key, value) {
    if (!res[value.name]) {
        res[value.name] = value;
    } else {
        res[value.name].type = [res[value.name].type, value.type].join(',');
    }
});

data = $.map(res, function (value) {
    return value;
});

console.log(data);

这会删除所有重复的＆＃34;名称＆＃34;因此，每个病房名称只有一个，所以只有35个对象（这是对的）。但只保留一种类型和百分比，并删除每个名称的其余部分。

阿曼，噢，伙计！您正在覆盖type而不是push ..

试试这个..

$.each(data, function (idx, value) {
    var type = value.type;

    if (!res[value.name]) {
        res[value.name] = value;
        res[value.name].type = []
    }

    res[value.name].type.push(type);
});

好吧，它没有处理你需要的其他字段，但是它应该指出你在代码中存在的逻辑错误......你应该能够自己完成任何进一步的工作..
