javascript - 如何将此数组转换为对象数组？

Question

这是我的数组:

[
    ['x', 1],
    ['y', 2],
    ['z', 3],
    ['F', "_180"],
    ['x', 1],
    ['y', 2],
    ['z', 3],
    ['t', 4]
    ['F', "_360"],
    ['x', 1],
    ['y', 2],
    ['z', 3],
    ['t', 4],
    ['m', 5]
    ['F', "_480"],
]

这是我想要实现的:

[{
    profile_180: {
        x: 1,
        y: 2,
        z: 3
    }
}, {
    profile_360: {
        x: 1,
        y: 2,
        z: 3,
        t: 4
    }
}, {
    profile_480: {
        x: 1,
        y: 2,
        z: 3
        t: 4,
        m: 5
    }
}]

我如何得到这个？

Answer 1

data = [
    ['x', 1],
    ['y', 2],
    ['z', 3],
    ['F', "_180"],
    ['x', 1],
    ['y', 2],
    ['z', 3],
    ['t', 4],
    ['F', "_360"],
    ['x', 1],
    ['y', 2],
    ['z', 3],
    ['t', 4],
    ['m', 5],
    ['F', "_480"],
];

var result = {};
var current = {};
data.forEach(function(row) {
  if (row[0] == 'F') {
    result['profile' + row[1]] = current;
    current = {};
  } else {
    current[row[0]] = row[1];
  }
});
console.log(result);
