如何将JS的对象类型转换成数组类型

Answer 1

只需要一句，arr.__proto__=[];但是要注意浏览器支持__proto__才行，最新的浏览器应该都支持。以下两种都可以解决此问题：function&nbsp;transform(obj){var&nbsp;arr&nbsp;=&nbsp;[];for(var&nbsp;item&nbsp;in&nbsp;obj){arr.push(obj[item]);}return&nbsp;arr;}或者public static void main(String[] args) {String [] s={"2","3","4"};int [] array=new int[3];for(int i=0;i<s.length;i++){array[i]=Integer.parseInt(s[i]);System.out.println(array[i]);}}
