[英]Regular expression to strip all non numeric characters except scientific notation
[英]How to match all the non numeric characters except a plus symbol using regular expression?
如何使用正则表达式匹配非0-9和+的任何字符? 我希望能够匹配除数字和加号以外的所有字符。
/ \\ D + /匹配所有不是数字的字符,但我希望它对于数字和+为假
按照regex101示例 ,使用[^0-9+]+
模式:
[^0-9+]+
Match a single character not present in the list below [^0-9+]+
+ Quantifier — Matches between one and unlimited times, as many times as possible, giving back as needed (greedy)
0-9 a single character in the range between 0 (index 48) and 9 (index 57) (case sensitive)
+ matches the character + literally (case sensitive)
您可以使用以下表达式:[^ 0-9。$]
