在javascript中使用正则表达式在破折号后匹配数字

Question

您好，我正在尝试在javascript中使用正则表达式来匹配破折号。

句子如下：

on agreeing to the resolution Agreed to by recorded vote: 238 - 182 (Roll no. 164).

我目前可以使用以下方式选择数字238：

(?:\s-\s)[0-9]+

但是我无法找到选择182的解决方案。

提前谢谢你的帮助！

您可以将每个人捕获到自己的组中，然后像这样对他们进行操作

string = "on agreeing to the resolution Agreed to by recorded vote: 238 - 182 (Roll no. 164)."    
var regex = /(\d+)\s*\-\s*(\d+)/;

string.replace(regex, "$1 what is this doing here $2");
=> "on agreeing to the resolution Agreed to by recorded vote: 238 what is this doing here 182 (Roll no. 164)."

您还可以删除它们，将它们添加到其中，等等。

string.replace(regex, "<strong>$1</strong> - <strong>$2</strong>");
=> "on agreeing to the resolution Agreed to by recorded vote: <strong>238</strong> - <strong>182</strong> (Roll no. 164)."

希望这可以帮助。
