从字符串中删除以某个字符开头的单词

Question

let string = 'the username @bradley is ready'

如何删除以@ 符号开头的所有单词，以便输出为“用户名已准备好”

Answer 1

 string.replace(/\@[^\s]*/g, "")

Use a regex to match every @ followed by non whitespace characters . Replace those with an empty string.

Answer 2

Here's a solution that should remove words starting with @ from your strings. It should preserve punctuation and not create duplicate spaces. (This solution does not exclude emails though)

 // \\s? optional preceding space // [^\\s.,!?:;()"']+ at least one character that isn't a space or punctuation // ([.,!?:;()"'])? an optional punctuation character, saved to a capture group function stripUserHandles (string) { return string.replace(/\\s?@[^\\s.,!?:;()"']+([.,!?:;()"'])?/g, "$1") } console.log( stripUserHandles('The username @bradley is ready') // The username is ready ) console.log( stripUserHandles('The username is @bradley. It is ready') // The username is. It is ready ) console.log( stripUserHandles('Alright "@bradley", Here\\'s your username') // Alright "", Here's your username )
