How to eliminate copy & Paste in textarea in javascript

Kindly, helpe me in this regard,

I have a textarea and should accept only alphanumeric characters upto 500 characters and if we do copy and paste more than 500 characters it should take 500 characters and remaining should eliminate.

kindly, provide me the code how to perform this

This is not really a Struts question. I know that there are some pages in my application that use JavaScript to limit the length. I suggest that you jump over to your favorite search engine and search for "limit textarea size".
