正则表达式是 / [^ \\\\ t] |（。） \ 1 / gi

在此测试： http://jsfiddle.net/Cte94/

它使用反向引用来搜索任何字符（。）后跟相同的字符 \1

it uses the backreference to search for any character (.) followed by the same character \1

除非检查重复的字符你的意思是 aaa => a

Unless by "check for duplicate characters" you meant that aaa => a

然后它是 / [^ \\\\ t] |（。）（？= \ 1）/ gi

请注意，两个正则表达式都不区分大小写。 A == a ，所以 Aa 是重复。如果您不想要它，请从 / gi

Be aware that both regexes don't distinguish between case. A == a, so Aa is a repetition. If you don't want it, take away the i from /gi
