javascript正则表达式只有在另一个模式不匹配时才排除模式

Question

A regex is needed in order to exclude sentences with wag[.|on] or ut[i|e] but only if NO sed[.|an] is present and allow all other sentences. any suggestions?
ie. exclude matches that are only wagon or only ute.

I tried /[^wag[on|.]]/ig.test(sentence) but this way will not allow exclusion. I need to select the "yes" sentences only as below.

Given the following sentences:
the sedan is fast <-- yes
other sed. is fast too <-- yes
the wagon is slow <-- no
other wag. is also slow <-- no
the ute is slow <-- no
other uti is also slow <-- no
the wag. and wagon slower then sed. or sedan <-- yes
the uti or ute is slower then sed. or sedan <-- yes
both wag. wagon and uti and ute are slow <-- no
nothing is fast or slow <-- yes

Answer 1

this does the trick

function isMatch(input) {
   var regno = /(wag[.|on]|ut[i|e])/gi;
   var regyes = /sed[.|an]/gi;
   return !regno.test(input) || regyes.test(input);
}

result:

Answer 2

/^(?:.*sed[.|an].*|(?:(?!wag[.|on]|ut[i|e]).)*)$/

您可以使用(?!)匹配与某些模式不匹配的字符串。
