如何创建多维数组，该数组的维数由字符串的长度确定，以创建数组 [英] How do I create a Multidimensional Array which the dimension is determined by the length of the strings to create the array

问题描述

我想从HTML中的input元素得到的给定字符串创建矩形多维数组。矩形的尺寸取决于字符串的长度。

I want to create a rectangular multidimensional array from a giving string gotten by input element in HTML. The dimensional of the rectangular will be determined by length of the string.

例如

ifmanwasmeanttostayonthegroundgodwouldhavegivenusroots

纯文本应组织为矩形。矩形（rxc）的大小应取决于消息的长度，以使 c> = r 和 c-r< = 1 ，
其中 c 是列数和r是行数。

我们的规范化文本长54个字符，规定了c = 8和r = 7的矩形：


ifmanwas
meanttos
tayonthe
groundgo
dwouldha
vegivenu
sroots


The plain text should be organized in to a rectangle. The size of the rectangle (​r x c​) should be decided by the length of the message, such that ​c >= r​ and ​c - r <= 1​, where ​c​ is the number of columns and ​r​ is the number of rows.
Our normalized text is 54 characters long, dictating a rectangle with ​c = 8​ and ​r = 7​:
"ifmanwas" "meanttos" "tayonthe" "groundgo" "dwouldha" "vegivenu" "sroots

const  myFunction = ()  =>
{
  let message = document.getElementById("message").value;
 if (message.length < 50) {
   alert ("Your Message can not be less than 50 Characters");
 }
  else {
  let removedSpace = message.replace(/[^a-zA-Z0-9]/g, '').toLowerCase();
  document.getElementById("noSpace").innerHTML = removedSpace;
  let squared = Math.sqrt(removedSpace.length);
  let column = Math.ceil(squared);
  let row = Math.floor(squared);
   document.getElementById("no-Space").innerHTML = row;
 }
}

我希望有一段array

I expect to have a block of array

推荐答案

让正则表达式执行此工作：

Let the regex do the job:

s = 'ifmanwasmeanttostayonthegroundgodwouldhavegivenusroots'
n = Math.ceil(Math.sqrt(s.length))
r = s.match(new RegExp(`.{1,${n}}`, 'g'))
console.log(r)
