我正在编写一个函数来检查对象是否包含“id”或“serif:id”等键。不幸的是这不能正常工作。

function returnIdPreferSerifId(object) {
    if (object.hasOwnProperty('serif:id' === true)) {
        return object['serif:id'];
    } else if (object.hasOwnProperty('id' === true)) {
        return object.id;
    } else {
        console.log(object)
        console.log(object.hasOwnProperty('serif:id' === true))
        console.log(object.hasOwnProperty('id' === true))
        throw `ID not found in Layer 1!`;
    }
}

测试对象为：

{ 
  id: 'ska',
  d: 'M255.848,145.321l19.839,0.054l12.677,8.62l6.085,-8.62l-8.62,-29.41l-30.488,13.637l0.507,15.719Z',
  style: 'fill:rgb(187,222,251);stroke:white;stroke-width:1.33px;' 
}

我希望该函数返回“ska”，因为它是对象 ID。相反，控制台显示

{ 
  id: 'ska',
  d: 'M255.848,145.321l19.839,0.054l12.677,8.62l6.085,-8.62l-8.62,-29.41l-30.488,13.637l0.507,15.719Z',
  style: 'fill:rgb(187,222,251);stroke:white;stroke-width:1.33px;' 
}

提前感谢您的帮助！
