[英]Regex - Right/Left trim + reduce more than one space in middle to one + remove line break at beginning & end incl reduction to two if in middle & >2
[英]Regexp example for input accepting one or more spaces at the beginning and at the end but not in the middle
regexp = / ^([a-zA-Z0-9 @_ \\ s。#] +)$ /; 我已經嘗試過了但是沒有工作
這樣的事情可以幫助您嗎?
// no spaces in the middle at all
regexp=/^[ ]{,2}[^ ]+?[ ]{,2}$/
// no two spaces in the middle, one is ok
regexp=/^[ ]{,2}[^ ]+?(?! )[^ ][ ]{,2}$/
