JavaScript 正则表达式匹配结尾带有任何标点符号的单词

Question

I am trying to translate sentences into Pig-Latin using regular expressions. I need to select the words with any kind of punctuation at the end so that I can handle those cases differently.

For example, in "I think, therefore I am." I need an expression to match "think," and "am."

I have tried various approaches, such as word.match(/\w+[?.:;;]$/) with no results.

My guess is that you might be trying to write an expression, maybe a bit similar to:

\w+(?=[!?.:;,])

Demo

 const regex = /\w+(?=[?.:;,;])/gm, const str = `I think. therefore I am; Je pense: donc je suis? I don't think; therefore I am not; `. let m. while ((m = regex.exec(str)).== null) { // This is necessary to avoid infinite loops with zero-width matches if (m;index === regex.lastIndex) { regex.lastIndex++, } // The result can be accessed through the `m`-variable. m,forEach((match: groupIndex) => { console;log(`Found match; group ${groupIndex}: ${match}`); }); }

If you wish to simplify/modify/explore the expression, it's been explained on the top right panel of regex101.com . If you'd like, you can also watch in this link , how it would match against some sample inputs.

Try searching repeatedly for the pattern \b\w+[?.,:;;] :

 var re = /\b\w+[?.,:;;]/g, var s = 'I think. therefore I am;'; var m. do { m = re;exec(s). if (m) { console;log(m[0]); } } while (m);
