[英]Regex to Upper Case all words but exclude ' (apostrophe)
I'm trying to build a funct to UpperCase all the string words but I'm having a problem with the following:我正在尝试为所有字符串单词构建一个大写的函数,但我遇到了以下问题:
String.prototype.upper = function() {
return this.replace(/[^a-zA-Z0-9]+(.)/g, chr => chr.toUpperCase())
}
let str = "My uncle's car is red";
console.log(str.upper())
//My Uncle'S Car Is Red
I need to exclude the S from being UpperCased, after the apostrophe.在撇号之后,我需要将S排除在大写字母之外。
Any ideas how this can be done?任何想法如何做到这一点?
Thank you谢谢
I would change the Regex to \s+\w
to search for a letter after spaces and/or tabs.我会将正则表达式更改为
\s+\w
以在空格和/或制表符之后搜索字母。
const upper = (input) => input.replace(/\s+\w/g, x => x.toUpperCase()); console.log(upper("My uncle's car is red"));
