您应该使用hasOwnProperty而不是!item.hasBox来检查对象是否有属性,否则您将得到错误的结果,例如'',0,null,undefined。。。 const items = [ {}, {hasBox: undefined}, {hasBox: true}, {hasBox: false}, {hasBox: null}, {hasBox: ''}, {hasBox: 0}];const updatedArray = items.map(item =>...

<script>varresult=Array.prototype.sort.apply([3,2,1]);console.log(result);</script> 结果: Array详细 (2)、call( ) 功能与apply类似,将函数作为指定对象的方法来调用,传递给它的是指定的参数。 对于第一个参数意义都一样,但对第二个参数:
myArray[0].name将返回John Doe 下面来看看数组排序。JS的Array对象有一个sort方法可用于排序,该方法可接受一个比较函数用于比较数组元素,决定排序顺序。 arr.sort([compareFunction]) compareFunction(a, b) 返回值 < 0, 则a排在b前 compareFunction(a, b) 返回值 > 0,则b在a前 ...
