[Solved] js: check if 2 elements has the same class and do something


If I understand correctly, when div.element1 is clicked on, you want find div.element1 on object2 and if it exists scroll to it. You can usee something like this:

$(".object1 > div").click(function (){
    var class = $(this).attr("class");
    if ($(".object2 > div." + class).length > 0){
         var matchingDivOn2ndObject = $(".object2 > div." + class)[0];

         $('html, body').animate({
               scrollTop: matchingDivOn2ndObject.offset().top
          }, 1000);
    }
});
