javascript 将每个单词推入一个数组

pushing each word to an array

提问by Hello World

If I had a string of text, how would I convert that string into an array of each of the individual words in the string?

如果我有一个文本字符串，我如何将该字符串转换为字符串中每个单词的数组？

Something like:

就像是：

var wordArray = [];
var words = 'never forget to empty your vacuum bags';

for ( //1 ) {
  wordArray.push( //2 );
}

1. go through every word in the string named words
2. push that word to the array

1. 遍历名为 words 的字符串中的每个单词
2. 将该词推送到数组

This would create the following array:

这将创建以下数组：

var wordArray = ['never','forget','to','empty','your','vacuum','bags'];

Don't iterate, just use split()which returns an array:

不要迭代，只需使用split()which返回一个数组：

let words = 'never forget to empty your vacuum bags',
  wordArray = words.split(' ');

console.log(wordArray);

And, using String.prototype.split()with the regular expression suggested by @jfriend00(in comments, below):

并且，使用@jfriend00String.prototype.split()建议的正则表达式（在下面的评论中）：

let words = 'never forget to empty your vacuum bags',
  wordArray = words.split(/\s+/);

console.log(wordArray);
