正则表达式与相似词完全匹配

Question

I have a pattern bellow:

var patt = /((name)|(names)*)/g;

var word = "namesnames";

word is according to pattern logicly, but word.match(patt) return :

["name", "", "name", "", ""]

which is wrong! i want "namesnames" result from match, please help me. thanks.

Answer 1

如果我正确理解了您想要的内容，则可以使其更简单：

var patt = /(names?)+/g;

Answer 2

问题是，当您应该执行((name)(?:s))+时，您使用(names)*表示0次或多次，表示1次或多次。
