您可以将正则表达式更改为：

You can change your regex to:

keywords = keywords.match(/\w+|"(?:\\"|[^"])+"/g);

而不是 [^] + 你有（？：\\| [^]）+ 允许 \或其他角色，但不是未转义的引用。

Instead of [^"]+ you've got (?:\\"|[^"])+ which allows \" or other character, but not an unescaped quote.

一个重要的注意事项是，如果你想让字符串包含一个文字斜杠，它应该是b e：

One important note is that if you want the string to include a literal slash, it should be:

keywords = 'pop rock "hard rock" "\\"dream\\" pop"'; //note the escaped slashes.

此外， \w + $ c $之间存在轻微的不一致c>和 [^] + - 例如，它将匹配单词ab * d，但不是 ab * d （没有引号）。考虑使用 [^\ s] + 代替，这将匹配非空格。

Also, there's a slight inconsistency between \w+ and [^"]+ - for example, it will match the word "ab*d", but not ab*d (without quotes). Consider using [^"\s]+ instead, that will match non-spaces.
