将每个单词推送到一个数组 [英] pushing each word to an array

问题描述

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？

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?

类似于：

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

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

1 =遍历名为words
2的字符串中的每个单词=将该单词推送到数组

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

这将创建以下数组：

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

推荐答案

不要迭代，只需使用 split（） 返回一个数组：

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

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

console.log(wordArray); // ["never", "forget", "to", "empty", "your", "vacuum", "bags"]
