You should mention that you have to have Firebug installed before you can use console.log sent from iPhone On Sep 22, 2007, at 3:58 PM, Pierre Spring <caillou-OI3hZJvNYWs@public.gmane.org> wrote:> > hi, > >> how can i test if a object is in the dom without a js alert>> >> for example >> >> $("filter_sum").value; > > if you use firebug in firefox, you can use > > console.log($("filter_sum").value); > > as described on [1]. > > hope this helps. > > greez . caillou > > links: > [1] http://www.getfirebug.com/console.html > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

if $(''filter_sum'') does not exist than the value can not
either..
in the original sample sample provided, they tested for $
(''filter_sum'') befor trying to read
$(''filter_sum'').value
this will not throw an error
if ($(''filter_sum'')) {
// "filter_sum" exists
alert($(''filter_sum'').value);
} else {
// "filter_sum" dosn''t exist
}
but this would....
if ($(''filter_sum'').value) {
// "filter_sum" exists
alert($(''filter_sum'').value);
} else {
// "filter_sum" dosn''t exist
}
