HomeWeb Front-endHTML Tutorial我一个正则表达式,如何判定里面不包含某个内容的_html/css_WEB-ITnose

本帖最后由 qq914260102 于 2013-11-06 15:06:27 编辑

比如:我要写一个正则表达式,不包含,"正确"两个字的(不正确、不正确的)的这种情况也要考虑进去。

如果反过来,必须元包含"正确"两个字的(不正确、不正确的)的这种情况也要考虑进去。
又该怎么写呢。

回复讨论(解决方案)

str.indexOf("正确")==-1不包含 反之包含

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script><script type='text/javascript'>	var reg=/正确/;	alert(reg.test("我鹅鹅鹅正确的"));	alert(reg.test("我鹅鹅鹅四十四"));</script>

这个是包含正确,不包含if(!reg.test("我鹅鹅鹅正确的"))

(?!(?:正确)).*
