regex - Not allowing \ through regular expression -


i have created below regular expression:

"format":"^[^/]*$"

to not allow forward slash , works. doesn't have allow forward slash. how can modify regular expression.

i tried below 1 doesn't work:

"format":"^[^/\\]*$"

the backslash special character in regular expressions. that's why need escape backslash, loses special meaning (don't copy code yet, below):

"format":"^[^/\\]*$"

if programming language uses backslashes escaping, might need apply 4 backslashes: first, parsed compiler, , later, regex engine process them time.

"format":"^[^/\\\\]*$"
