Need regex for the “Project name” with following condition. Expected Result: Take alphabetical, alpha numeric, alpha numeric symbolic Actual Result:
1. Take alpha – Pass 2. Take Numeric – Pass 3. Take Alpha numeric – Pass 4. Take alpha numeric special characters - Pass 5. If Only special characters – Fail
that is, Everything is allowed but if it is just special characters and no text than it’s a problem. **Example:
- zjna5726$7&^#bsg //allowed
- %&*% // just special characters not allowed
- I tried /^[ A-Za-z0-9_@./#&+-]*$/ but did not help
- ^([w+d+]+)((-)([w+d+]+))* //did not help it is only excepting one character in between only.
