{couid: 1006, couname: "3阿", coname: "娜", couprice: "6", couduration: 3, maxnum: 3, residue: 3} coname : "娜" couduration : 3 couid : 1006 couname : "3阿" couprice : "6" maxnum : 3 residue : 3怎么去除coname

如果你想从该对象中删除 "coname" 属性，可以使用 delete 操作符。例如：

var course = {couid: 1006, couname: "3阿", coname: "娜", couprice: "6", couduration: 3, maxnum: 3, residue: 3};
delete course.coname;
console.log(course);

这将输出：

{couid: 1006, couname: "3阿", couprice: "6", couduration: 3, maxnum: 3, residue: 3}

如你所见，"coname" 属性已经从对象中删除了。
