Javascript - 在句子中反转单词

Question

请引用- https://jsfiddle.net/jy5p509c/

var a = "who all are coming to the party and merry around in somewhere";

res = ""; resarr = [];

for(i=0 ;i<a.length; i++) {

if(a[i] == " ") {
    res+= resarr.reverse().join("")+" ";
    resarr = [];
}
else {
    resarr.push(a[i]);
}   
}
console.log(res);

最后一个词不反转，不在最终结果中输出。不确定缺少什么。

Answer 1

问题是你的 if(a[i] == "") 最后一个词不满足条件

var a = "who all are coming to the party and merry around in somewhere";

res = "";
resarr = [];

for (i = 0; i < a.length; i++) {
  if (a[i] == " " || i == a.length - 1) {
    res += resarr.reverse().join("") + " ";
    resarr = [];
  } else {
    resarr.push(a[i]);
  }
}

document.body.appendChild(document.createTextNode(res))

你也可以试试更短的

var a = "who all are coming to the party and merry around in florida";

var res = a.split(' ').map(function(text) {
  return text.split('').reverse().join('')
}).join(' ');

document.body.appendChild(document.createTextNode(res))
