Question

Is there a jQuery equivalent to this prototype code?

Ajax.Responders.register({
  onException: function(x,y)
  {
    if(y.message!="Syntax error") new Insertion.After("toperrorbox","<p style='color:red'>"+y.message+"</p>");
  }
});

Answer 1

http://docs.jquery.com/Ajax/ajaxError#examples

$('#toperrorbox').ajaxError(function (event, request, settings) {
   $(this).after("<p style='color:red'>"+ request.responseText +"</p>");
}

Attach a function to be executed whenever an AJAX request fails.
