Question

我使用JavaScript代码从页面元素输入中对字符串进行排序，它是这样的：

a=document.getElementsByTagName("textarea");
input=a[0].innerHTML;
input=input.split(',');
input=input.sort();
alert(input);
var str=input.join();
str=str.replace(" ","");

输入字符串有逗号和空格，因此如果输入类似于：

yet, must, has, wants, would, some, are, let, own, can, could, which, his, had, got, our, only, also, every, after, other, may, you, them, while, ever, what, get, its, why, their, her, him, just, say, this, than, have, able, least, like, whom, nor, cannot, into, among

输出是：

able, after, also, among, are, can, cannot, could, ever, every, get, got, had, has, have, her, him, his, into, its, just, least, let, like, may, must, nor, only, other, our, own, say, some, than, their, them, this, wants, what, which, while, whom, why, would, you,yet

你可以注意到它应该在你之前，所以什么错了????

Answer 1

你需要用空格分割。

input = input.split(', ');

否则你在字符串的开头有一个空格。

var input = 'yet, must, has, wants, would, some, are, let, own, can, could, which, his, had, got, our, only, also, every, after, other, may, you, them, while, ever, what, get, its, why, their, her, him, just, say, this, than, have, able, least, like, whom, nor, cannot, into, among';
console.log(input.split(', ').sort());

.as-console-wrapper { max-height: 100% !important; top: 0; }

Answer 2

您应该在排序前删除空格：

var input = 'yet, must, has, wants, would, some, are, let, own, can, could, which, his, had, got, our, only, also, every, after, other, may, you, them, while, ever, what, get, its, why, their, her, him, just, say, this, than, have, able, least, like, whom, nor, cannot, into, among';
input = input.replace(/\s+/g, '').split(',').sort();
console.log(input);

javascript排序与字符串无法正常工作
