在Javascript中将数字转换为数组 [英] Convert number into array in Javascript

问题描述

当我输入一个带有提示符 var myNumber = parseInt（提示符（...））的数字时，我想将它转换为数字数组。当我尝试 myNumber = myNumber.split（）时，它返回：

When I type a number with prompt var myNumber = parseInt(prompt("..."))I want it to be converted into an array of numbers. When I try with myNumber = myNumber.split("") it returns:

对象1没有方法'拆分'

Object 1 has no method 'split'

请帮助我

推荐答案

你不能拆分int，你需要有一个字符串数据类型才能使这个代码有效！

You cannot split the int, you need to have a string data type for this code to work!

所以，我想要建议首先拆分它，然后将其转换为int

So, I would like to suggest to first split it and then convert it to int as

var numbers = "1, 2, 3";
var eachNumber = numbers.split(",");
/* now parse them or whatso ever */

这将有效，因为你'只是拆分字符串。然后你将按照第一种方法（你的方法）解析它。

This will work, as you're just splitting the string. And then you will parse it just the way you did it in the first method (of yours).
