javascript - 我想按垂直顺序打印一个字符串数组， const myArr = ['Google' , 'Dell' ,'Atlas' ];

Question

应该是这样的，首先是垂直打印 Google，然后是 Dell，然后是 Atlas。我的意思是每个单词的每个字母都会以垂直方式打印。我做了如下:

const myArr = ['Google', 'Dell', 'Atlas'];

function myPattern(arr) {
  arr.forEach(function(elem) {
    let line = "";
    elem.split('').forEach(function(item) {
      line += `${item} `;
    })
    console.log(line);
  });
}
myPattern(myArr);

Answer 1

如果您希望它们并排显示，这应该适合您(在下面运行):

const myArr = ['Google', 'Dell', 'Atlas'];

// function to check if value is empty
function returnValue(value) {
  if (typeof value != 'undefined' && value.length > 0) {
      return " " + value + " ";
  }
  return "   ";
}

function myPattern(arr) {
  let arrLength = arr.length;
  let finished = false;
  let level = 0;
  
  do {
    let result = "";
    
    for(let i=0; i<arrLength; i++) {
       result += returnValue(arr[i][level]); 
    }
    
    let row = result.trim();
    
    if(row != "") {
      console.log(row);
    } else {
      finished = true;
    }
    
    level++;
  } while(!finished);
}

myPattern(myArr);
