如何从Javascript中的字符串中删除以某个字符开头的单词

Question

我有一个像

'here is some #tweet from @someone to @somebody-else'

并且我需要删除所有以@mentions开头的单词（和短语），并返回不包含它们的字符串，以使其变为

'here is some #tweet from to'

如何在Javascript中做到这一点？

谢谢！

Answer 1

var str = 'here is some #tweet from @someone to @somebody-else';

str = str.replace(/\s?@\S+/g, '');

Answer 2

var s = 'here is some #tweet from @someone to @somebody-else';
s = s.replace(/\s?@[\w-]+/g, "");
//here is some #tweet from to
