<script type="text/javascript">
var objBj="animated fadeInUp marginImgThis imgSrcA imgAHover";
var strs=[];
    strs=objBj.split(" ");
var newArr=[];


            
    $.each(strs,function(index,value){
          if(value!="imgAHover"){
              newArr[index]=value;
              }
        
        })
        alert(newArr[0])
</script>
