javascript - 将 json 文件转换为其他格式

Question

如何最好地将 json 文件转换为其他格式？我读到了“map”方法，但不知道如何使用它。

[{"Southern":"9"},{"South-West":"83"},{"South-East":"448"},{"Western":"638"},{"North-Western":"706"},{"Eastern":"710"},{"North-East":"1055"}]

我想转换:

        [
            ['Southern', 9],
            ['South-West', 83],                   
            ['South-East', 448],
            ['Western', 638],
            ['North-Western', 706],
            ['Eastern', 710],
            ['North-East', 1055],

        ]

代码:

 data.map(function(e) {
    ..........
    });

Answer 1

newData = data.map(function(e) {
    var key = Object.keys(e)[0];
    return [ key, parseInt(e[key], 10) ];
});

但是，如果将其转换为单个对象，似乎会更有用:

{ 
    'Southern': 9,
    'South-West': 83,
    'South-East': 448,
    'Western': 638,
    'North-Western': 706
    'Eastern': 710
    'North-East': 1055
}

这可以通过以下方式完成:

newObject = {};
data.forEach(function(e) {
    var key = Object.keys(e)[0];
    newObject[key] = e[key];
});
