Question

我有一个object，例如“模型”：

var model = {
    comments: {
        123: "I disagree on this",
        42563: "Sounds correct"
    },
    answer: {
        123: "No",
        87: "Yes"
    }
};

我需要将“模型” object重构为：

var wishModel = {
    123: {
        answer: "No",
        comments: "I disagree on this"
    },
    87: {
        answer: "Yes"
    },
    42563: {
        comments: "Sounds correct"
    }
};

我在使用JavaScript objects方面是一个新手，并且不知道从哪里开始。

Answer 1

这是一种符合新手的方式：

var wishModel = {};

for (var key of ["comments", "answer"]) {
  for (var prop in model[key]) {
    wishModel[prop] = wishModel[prop] || {};
    wishModel[prop][key] = model[key][prop];
  }
}

Answer 2

您可以像下面一样使用<script type="text/javascript"> if (screen.width <= 720) { window.location = "indexm.php"; } else { window.location = "index.php"; } </script>遍历对象
