javascript - 正则表达式仅匹配具有特殊字符的长字符串中的单词

Question

我有一个 javascript 函数，我试图匹配长字符串中的每个单词，我的匹配工作基本上只是在空格上爆炸，尽管我想修改我的正则表达式以自动删除特殊字符，例如 ! , - 等

例如:

var a = 'This! is a sample sentence, only words should be extracted from it!!';

我正在寻找正则表达式的结果

{This,is,a,sample,sentence,only,words,should,be,extracted,from,it}

Answer 1

试试这个

> var a = 'This! is a sample sentence, only words should be extracted from it!!';

> a.match(/\w+/g);

["This", "is", "a", "sample", "sentence", "only", "words", "should", "be", "extracted", "from", "it"]
