如何使用正则表达式删除字符串中最后一个字母字符后的任何非字母字符？
[英]How do I use regex to remove any non alpha characters after last alpha character in string?
问题描述
So the rule I would like to apply to clean the strings I have is:
所以我想应用来清理我所拥有的字符串的规则是：
Search for last character in that has a letter between AZ/i and remove all characters after it.搜索在 AZ/i 之间有字母的最后一个字符，并删除其后的所有字符。 Like this:像这样：
"WASHER," -> "WASHER" (R is last alpha character)
"VALVE,NEEDLE," -> "VALVE,NEEDLE" (E is last alpha character)
"HOSE,HYDRAULIC. 3466" -> "HOSE,HYDRAULIC" (C is last alpha character)
"WASHER . " -> "WASHER" (R is last alpha character)

I found it, by using: [^AZ]+$我找到了，通过使用：[^AZ]+$
console.log("WASHER,".replace(/[^AZ]+$/,"")) console.log("VALVE,NEEDLE,".replace(/[^AZ]+$/,"")) console.log("HOSE,HYDRAULIC. 3466".replace(/[^AZ]+$/,"")) console.log("WASHER . ".replace(/[^AZ]+$/,""))
