正则表达式匹配所有字符到某个标记

I'm trying to write a regex to match all characters up to a '/' My current regex only matches the first character of the string

我正在尝试编写一个正则表达式来匹配所有字符到'/'我当前的正则表达式只匹配字符串的第一个字符

var regex = /[^\/]/
regex.exec("something/15")

This will give me 's'. I have also tried

这会给我''。我也试过了

var regex = /.*[^\/]/

but it returns the whole string undelimited by '/'. I have taken a look at this other SO post as well.

但它通过'/'返回整个字符串不受限制。我也看过其他SO帖子。

Javascript regular expression: match anything up until something (if there it exists)

Javascript正则表达式:匹配任何东西直到某些东西(如果它存在)

You need to use start anchor and quantifier * to match 0 or more characters until a / is found:

您需要使用开始锚点和量词*来匹配0个或多个字符,直到找到/:

var regex = /^[^\/]*/
