每个单词中的字符数

Posted 2021-05-03

我想开发一个代码来计算句子中每个单词的字符数，并测试它是否在2到14个字符之间。

如果它在2到14个字符之间，那么result1 = true

否则result1 = false

这是我的代码：

var sentence = "Now is the time for all men"
var re = /\s+/;
var resultat1 = false;
var nameList = sentence.split(re); //cutting the sentence into words
console.log(nameList);               //List of words in the sentence
var NbMot = nameList.length; //Number of words in the sentence
var NbCarMot = 0; //Numer of caracter in each word
for (i = 0; i < NbMot; i++) {
  NbCarMot = (nameList[i].length); //Numer of caracter in each word
  console.log(NbCarMot);
}
console.log(NbCarMot);
if (NbCarMot <= 14) {
  resultat1 = true;
}
console.log(resultat1)

答案

var sentence = 'hello Good morning';
var resultat1 = true;
var re = /\s+/;
var nameList = sentence.split(re);    //cutting the sentence into words

for (i = 0; i < nameList.length; i++) {
    var len = nameList[i].length; //Numer of caracter in each word
    if (len < 2 || len > 14)     //Test your counts
    {
        resultat1 = false; // if not match set variable to false and break
        break;
    }
}

alert(resultat1); // check your final result

另一答案

我想开发一个代码来计算一个句子中每个单词的字符数，并测试它是否在2到14个字符之间，

一旦发现第一次违反规则（2到14个字符），您需要立即退出循环。

使用some尝试这个简单的

var isInvalid = sentence.split( /\s+/ ).some( s => s.length < 2 || s.length > 14 );
