Javascript Regex to filter String

I need Regex to filter string to fit with the following conditions :

Example Valid Text :

Developers trust #StackOverflow to help solve #coding problems and use Stack Overflow Careers to find job opportunities. Please visit https://stackoverflow.com/

Example Invalid Text :

Developers trust #StackOverflow to help solve #coding problems and use Stack Overflow Careers to find job opportunities. Please visit https://stackoverflow.com/ or https://stackoverflow.com/company/about

Invalid string above because there are containing two URL.

Any help would be appreciated and thank you very much :)

I think this will help you

^(?!^([^#]*#[^#]*){5,}$)(?!(.*http(s{0,1}):\/\/){2,})(?=.*[a-z]).{0,300}$
  • (?!^([^#]*#[^#]*){5,}$) this will ensure that string should not contain more then 4 #
  • (?!(.*http(s{0,1}):\/\/){2,}) this will ensure that string should not contain more then 2 url
  • (?=.*[a-z]) this will ensure that string should contain at least 1 lower case letter
  • .{0,300} this will ensure that string should contain not more then 300 charter
