删除 object 中多个 key 有什么优雅的写法吗？

Question

deleteobject.nid
deleteobject.uuid
deleteobject.desktop
deleteobject.isHide
deleteobject.sortId
deleteobject.dateBean
类似这种需要删除很多个元素的有什么优雅的写法吗？

Answer 1

把key值放到一个数组中，然后循环删除key值：varkeys=["nid","uuid","desktop","isHide","sortId","dateBean"];keys.forEach(function(item){deleteobject[item]});

Answer 2

//首先定义一个函数来判断数组中是否有某个元素，我选择给数组对象拓展一个方法Array.prototype.contains=function(needle){for(iinthis){if(this[i]==needle)returntrue;}returnfalse;};//然后这里模拟一个要删除的arrayvardelArr=['nid','uuid','desktop','isHide','sortId','dateBean'];for(varkeyinobject){if(delArr.contains(key)){deleteobject[key];}}
