There is error in syntax of jquery.. You missed out syntax of data. This should be like this-

function deleteMediaFromDatabase(val)
{
$.ajax({ url: 'deleteMediaFromDatabase.php',
     data: {'vals' : val},
     type: 'post',
     dataType:'json',
     success: function(output) {
                  alert(output);
              },
      error: function(request, status, error){
        alert("Error: Could not delete");
      }
});
}
