Ok I did it, how would anyone ever need.

function isFan(a) 
{
    var myString = a; 
    var fan_page_id = myString.split(',');

    for (var i=0;i<fan_page_id.length;i++)
    { 
        FB.api('me/likes/'+fan_page_id[i] ,function(response) 
        {
            if (response.data.length == 0) 
            {
                $("#myModal2").modal()   
                brake;
            }else{
                //OK i like
            }
        });
    }
}
