查找字符串中长度最大的所有单词 [英] Find all the words in a string which have the greatest length

问题描述

我想从字符串中找到长度最大的所有单词.

I want to find all the words from the string which have the greatest length.

目前，结果只是长度最大的第一个:'jumped1'，而我想要它们全部: ['jumped1'，'jumped2'] .

At the moment, the result is just the first with the greatest length: 'jumped1', whereas I want them all: ['jumped1', 'jumped2'].

我该如何调整以下内容?

How can I adapt the following?

function test(str) {

  var newStr = str.split(' ');
  var nu = 0;
  var word =null;

  for(var i=0; i < newStr.length; i++){
     if(newStr[i].length > nu){
       nu = newStr[i].length; // length
       word = newStr[i]; // word

     }    
  }
  return word;
}

console.log(test("The quick brown fox jumped1 over the lazy dog - jumped2"));

推荐答案

找到最长的单词时，与其分配给变量 word ，而不是将其推入最长的单词数组，而不是将其分配给变量.找到新的最长单词时，您必须处理空白数组.

Instead of assigning to a variable, word, when you find longest word, push it to an array of longest words. You have to handle blanking the array though when a new longest word is found.

function test(str) {
  var split_string = str.split(' ');
  var longest_length = 0;
  var words = [];
  for(let string of split_string){
     if(string.length > longest_length){
       words = [string];
       longest_length = string.length;
     } else if (string.length == longest_length){
       words.push(string);
     }
  }
  return words;
}

console.log(test("The quick brown fox jumped1 over the lazy dog - jumped2"));
