arrayObj.shift(); //移除最前一个元素并返回该元素值,数组中元素自动前移 arrayObj.splice(deletePos,deleteCount); //删除从指定位置deletePos开始的指定数量deleteCount的元素,数组形式返回所移除的元素 5、数组的截取和合并 arrayObj.slice(start, [end]); //以数组的形式返回数组的一部分,注意不包括 end ...
有一种,不能迭代map、json对象,只能迭代数组和list。 数组和list都靠下标取值,且js中并无list或map的概念。 所以,数组和list等同,在这里示例中。 map和json对象等同,在这里示例中。【唯一区别在于下面示例中map的key并没有引号,而json对象的key一定要被引号引起来】 [$().each 迭代数组] [$().each 迭代map...
We must first iterate the prototype chain and we list all the properties in an array. Then we check if each single property is a function.An easy way to make sure we don’t duplicate methods as we navigate the prototype chain (like constructor which is always present), we use a Set ...
