明扼要说明一下吧:先new一个Array,遍历NodeList,然后将每一个单独的元素push到数组变量里,最后操作数组变量,over。有没有智商受辱的感觉? 下面是在网上google到的,两行代码就可以将NodeList转换成Array来使用了: varanchors = document.getElementsByTagName("a");vararr = Array.prototype
通过测试,使用如:obj instanceof Object的形式,只能是判断两种类型Object和Array,其中Boolean、Number、String可以判断,但是会返回false,如上面i和b变量;如果判断为null或者undefind会报Uncaught TypeError: Right-hand side of 'instanceof' is not an object这样的错误。 测试5: 直接通过Array.isArray(obj),javascri...

【Java 进阶篇】JavaScript Array数组详解,JavaScript数组是一种有序的数据集合,它可以存储多个值。数组的每个值称为元素,每个元素都有一个与之关联的索引,用来标识
filter<S>((value: Vault, index: number, array: Vault[]) => boolean, any) 返回满足回调函数中指定的条件的数组的元素。 find((value: Vault, index: number, obj: Vault[]) => unknown, any) find<S>((this: void, value: Vault, index: number, obj: Vault[]) => boolean, any) ...
