To allow only one forward slash "/" in a regular expression, you can use the following pattern:
1
|
^[^/]*/[^/]*$ |
Explanation:
- ^ : Start of the line
- [^/]* : Zero or more characters that are not a forward slash
- / : The forward slash character
- [^/]* : Zero or more characters that are not a forward slash
- $ : End of the line
This regex pattern will only match strings that contain exactly one forward slash.
