I am trying to find everything in a paragraph that is not abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 and not space / /gi

/[^a-zA-Z0-9]|[^ ]/gi

the above doesn't work!

回答1:

You could also try with:

/[^a-zA-Z0-9\s]/gi

回答2:

If you only want to exclude spaces use:

[^ ]*

Test the regex here if you want.

回答3:

try ^[\d\w]*$ or ^[\w]*$ as reg' Expression means from ^(start) to $(end) match 0-9a-zA-Z only

for c++ ansistring="^[\\d\\w]*$";
