分别打印元音和辅音的代码不起作用 [英] Code for printing vowels and consonants separately not working

问题描述

输入一个字符串。然后执行：
每个字母都打印在新行上。
然后，按照与中出现的顺序打印元音。
然后，辅音按照它们出现的顺序打印

Input a string. Then perform:: Each letter is printed on a new line. Then the vowels are printed in the same order as they appeared in . Then the consonants are printed in the same order as they appeared in

样本输入

javascriptloops

样本输出

a
a
i
o
o
j
v
s
c
r
p
t
l
p
s

这就是我所做的

let a = [];
let b = [];
vowelsAndConsonants("javascriptloops");

function vowelsAndConsonants(s) {
  let i;
  let k = 0,
    j = 0;
  s.trim();
  s.toLowerCase();
  for (i = 0; i <= s.length; i++) {
    if (s.charAt(i) === "a" || s.charAt(i) === "e" || s.charAt(i) === "i" || s.charAt(i) === "o" || s.charAt(i) === "u") {
      a[k] = s.charAt(i);
      k++;
    } else {
      b[j] = s.charAt(j);
      j++;
    }
  }

}

for (let i = 0; i <= a.length; i++) {
  console.log(a[i]);
}
for (let i = 0; i <= b.length; i++) {
  console.log(b[i]);
}

推荐答案

执行此操作的最佳方法是使用正则表达式匹配元音和辅音，然后打印每个元音和辅音。

The best way to do this is using regular expression to match vowels and consonants, and then print each of them.

下面是工作代码段：

Below is the working code snippet:

        function vowelsAndConsonants(s) {
            var vw =s.match(/[aeiouAEIOU]+?/g); //regular expression to match vowels
            var con=s.match(/[^aeiouAEIOU]+?/g); //regular expression to not match vowels, ie. to match consonants
            printOnConsole(vw); //print vowels
            printOnConsole(con); //print consonants
       }

      //function to print values on console.
       function printOnConsole(arrPrint){
         for(var i=0;i<arrPrint.length;i++){
            console.log(arrPrint[i]);
          } 
       }
