[Proto-Scripty] Re: Using a prototype function in dynamic content.
Ah, now, that's interesting. I did try to use evalScripts, but I couldn't find any clear examples of how or where to apply it. I tried putting it in the places it seemed logical, but without effect. So, ok, I have an HTML page includes an onclick to fetch some content which will include scripts. The JS functions to handle this are in an external file. Do I put the evalScripts() in onclick="getStuff(param, param).evalScipts(); or do I apply it to the returned text before putting it in innerHTML like var thereturn = http_request.responseText.evalScripts(); document.getElementById(div).innerHTML = thereturn; I tried both, but couldn't get either to work.

[Proto-Scripty] how can i implement rails' link_to_remote :submit options using Ajax.updater?
Hello.
<%= link_to_remote 'click here', :update=>'some_div', :url=>
{:action=>'some'}, :submit=>'group' %>
is what I want to implement using Ajax.updater.
To do this I coded ( it is invoked when I clicked some link or button,
whatever )
new Ajax.Updater('some_div', url(:action=>'some'),
{ parameters: $('group').serialize(true), method: 'get'} );
group div looks like below:
<%= radio_button_tag(:myvalue, 1 %>
<%= radio_button_tag(:myvalue, 2 %>
on the controller's 'some' looks like below
def some
if params[:myvalue] == blah blah
end
if i use link_to_remote with submit options, it worked properly.
but in case of my code using Ajax.updater, params[:myvalue] is not set
properly.
What's wrong with me?
Somebody help me.
Thanks.

[Proto-Scripty] Re: Escaping Input
Hi,
I'm surprised by the POST data you quoted, but it doesn't matter, I'm
pretty sure I know what's wrong.
I was hurrying too much when posting my reply. You don't have to URL-
encode the JSON string if you're going to give Ajax.Request a
parameters *object* rather than parameters *string*, because Prototype
will do it for you -- which is half the point of using an object. So
drop the encodeURIComponent bit:
// Using an object:
entry = Object.toJSON($('busCalForm').serialize(true));
new Ajax.Request(
"modules/buscal/processes/saveBooking.php", {
parameters: {
year: year,
recnum: busmstr_id,
json: entry
},
onSuccess: busCal.gotEntry.bind(this),
onFailure: busCal.gotFailure.bind(this)
});
// Using a string (not recommended, data gets transformed to an object
// and then back again -- but it demonstrates using the
// encodeURIComponent function
entry = Object.toJSON($('busCalForm').serialize(true));
new Ajax.Request(
"modules/buscal/processes/saveBooking.php", {
parameters:
"year=" + encodeURIComponent(year) +
"&recnum=" + encodeURIComponent(busmstr_id) +
"&json=" + encodeURIComponent(entry),
onSuccess: busCal.gotEntry.bind(this),
onFailure: busCal.gotFailure.bind(this)
});
Note that I'm escaping all of the components, although if you *know*
year and busmstr_id won't include any characters that are special in
URLs, you can skip it. Again, though, best to use the object feature
of Ajax.Request and let it handle URL-encoding.
Sorry for the bum steer earlier, rushing too much. "Do less, better"
should be my motto. ;-)

[Proto-Scripty] Re: IE, attachEvent to div
Hi Jake,
I know you said to cancel your post (it had already been posted), so
you're not expecting an answer, but:
> element = Element('div') // Doesn't work when created this way.
It's "new Element(...)", not "Element(...)". (See [1], scroll down to
"Element as a constructor").
> element.attachEvent('onclick', function(evt) {alert('hello')} ); //
If you're using Prototype, why not use Prototype?[2]
[1] http://prototypejs.org/api/element
[2] http://prototypejs.org/api/element/observe

[Proto-Scripty] Simple Yes/No prompt inside a layer with timeout
I'm looking for a simple (Yes/NO) prompt with a timeout and fade away function so it can "live" on the screen, accept "Y" or "N" or enter or escape, with "N" as the default, and Escape as cancel. It should live within a layer and disappear after a set number of seconds. Any leads?

[Proto-Scripty] IE, attachEvent to div
I am using prototype 1.6.0.3 and IE8. Although I think the same
problem occurred in IE7. Why do the following lines of code give
errors?
element = Element('div') // Doesn't work when created this way.
element.attachEvent('onclick', function(evt) {alert('hello')} ); //
can't attach event.
This doesn't work either:
element = Element('div')
Event.observe(element, 'click', function(evt) {alert('hello')});
However, when I do not use prototype to create the div element, both
of these do not generate errors:
element = document.createElement('div');
element.attachEvent('onclick', function(evt) {alert('hello')} );
element = document.createElement('div');
Event.observe(element, 'click', function(evt) {alert('hello')});
I was thinking that a div created with
element = Element('div')
can do everything that a div created with
element = document.createElement('div');
can do, but it will not allow me to attach an event for some reason.
Any ideas as far as why the first two don't work?
Thanks.
