类数组对象

可以使用Array.prototype.slice.call()方法将HTMLCollection/NodeList/伪数组转换成数组，示例如下：，，“javascript，var htmlCollection = document.getElementsByTagName(‘div’);，var nodeList = document.querySelectorAll(‘div’);，var pseudoArray = {0: ‘a’, 1: ‘b’, 2: ‘c’, length: 3};，，var arrayFromHtmlCollection = Array.prototype.slice.call(htmlCollection);，var arrayFromNodeList = Array.prototype.slice.call(nodeList);，var arrayFromPseudoArray = Array.prototype.slice.call(pseudoArray);，“
