XSS可以用handontable而不用PHP吗？

Question

My webpage has the php extension, but there is no php code in it. There is handsontable and user would insert some numbers and get some cool JS effects on the same page. When I was writing the code for comments, I used strip_tags as a protection, but that was working for PHP. Now , I am curious if there is any danger leaving handsontable as it is?

Answer 1

Well the question is, can a visitor alter the content in a way that another visitor will load something to their browser that was not intended by developers. If it's purely client side and if you do not accept any user inputs, I think its pretty safe. If you have any unused php scripts, remove them.
