Regular Expression to limit characters to 5000

Question

I need a regular expression to simply limit the number of characters in a textarea to 5000. If there are more secure regular expressions I could use, I am open to suggestions.

Thanks

Answer 1

^.{0,5000}$ should work. Although using a regular expression for this is probably an odd choice.

Answer 2

You will always get the job done with:

^[\\s\\S]{0,5000}$

• First there´sa character class that says: match whitespace ( \\s ) or non-whitespace ( \\S ) -- ie any possible character
• Repeat that between zero and 5000 times.
