Just add .length after $('.new').find('.tr') in check condition

$('button').click(function(){
    if($('.new').find('.tr').length){
        $('.new1').css("position", "absolute");
        alert('absolute');
    }
    else{
        $('.new1').css("position", "relative");
        alert('relative');
    }
});

Do this

$('.new').find('.tr').length!=0 to check whether element exists or not.

According to your HTML, 

$(document).ready(function(){
    $('button').click(function(){
        if($('.new').find('div').hasClass('rt')){
          $('.new1').css("position", "absolute");
          alert('absolute');
        }
        else{
          $('.new1').css("position", "relative");
          alert('relative');
        }
    });
});
