Question

Hi I want to hide many elements. Do I need to hide each individually or can I use FOR?
If so, how to do it?

I’ve got this code:

   for (I=0; I <11; I++){
      $('div#r'+I).hide();
   }

But I don’t know what exacly write inside FOR and this one is probably wrong written.

Answer 1

you can hide all the divs starting with a specific id with

 $('div[id^="r"]').hide();

but I would recommend giving them a class which makes it easier

 <div class="hidethis" id="r0">hidden</div>
 <div class="hidethis" id="r1">hidden</div>
 <div class="hidethis" id="r2">hidden</div>

then

  $(".hidethis").hide();
