Question

我需要转换这个json对象：

"forms":
        {
            "Circle":
            {
                "color" : "red",
                "size" : "1"
            },
            "Square":
            {
                "color" : "blue",
                "size" : "3"
            },
            "triangle":
            {
                "color" : "black",
                "size" : "4"
            }
        }

进入javascriptArray。该数组应包含formType，颜色和大小。我创建了以下脚本

var formsArr=[]; 
$.each(forms, function(i, obj){ var form={color: obj.color, size: obj.size};
                formsArr.push(form);

该数组仅包含颜色和大小。我希望它也包含formType ie。圈，我怎样才能获得钥匙？

这是一种方法：

var forms = {
  "Circle": {
    "color" : "red",
    "size" : "1"
  },
  "Square": {
    "color" : "blue",
    "size" : "3"
  },
  "triangle": {
    "color" : "black",
    "size" : "4"
  }
};

var result = Object.keys(forms).map(function(key) {
  return { type: key, color: this[key].color, size: this[key].size };
}, forms);

使用jQuery：

var result = $.map(forms, function(val, key) {
  return { type: key, color: val.color, size: val.size };
});
