Check if a variant div exists

Question

I have several Ivs with the class prefix "webserver_[.. ]" and would like to check if any div with the prefix "webserver_[.. ]" exists, only with jQuery, how to do?

Answer 1

You can use ^= which is a pseudo-selector meaning that a given attribute "begins with" and so search for elements whose class starts with this string "webserver_".

Example:

$('[class^="webserver_"]').length // vai dar o numero de divs existentes
