[Proto-Scripty] using eval inside Ajax Request
Maybe this evals, but the functions do not get exposed. How should I
be doing this?
function reCalc() {
var sendSymsN = new Ajax.Request(url, {method:'post', onSuccess:
function() {
var evalMe=decode(transport.responseText); //
returns
( fname = function() { doStuff; }
eval(ev);
}
}
);
}

[Proto-Scripty] Re: using eval inside Ajax Request
Interesting, I've never done that before. What about this:
eval("someVar=function() { this.elm=$('getElm');
this.elm.innerHTML='test'; };");
alert($('getElm').innerHTML);

[Proto-Scripty] Re: using eval inside Ajax Request
Sorry, should be:
eval("someVar=function() { this.elm=$('outputs');}; s=new
someVar(); s.innerHTML='test';");
alert($('outputs').innerHTML);
// not 'test'

[Proto-Scripty] Re: using eval inside Ajax Request
I was trying to demonstrate my problem, it's not what's actually in my
code. It's seems that $('test') inside my eval is not the same as the
$('test') outside of it. When I try to run that code I'd expect $
('test')'s HTML to change, but it doesn't. Why not and how can I make
it do that?

[Proto-Scripty] Autocompleter.DB
I want to create an autocompleter that uses HTML database storage.
What I'm intending to it modify Autocompleter.Local. My problem is
that I'm not sure how to fit these 2 pieces of code together:
>From Autocompleter:
getUpdatedChoices: function() {
this.updateChoices(this.options.selector(this), searchDB
(this.getToken()));
}
DB function:
function searchDB(searchThis) {
db.transaction(function(tx) { tx.executeSql(" SELECT
info FROM list WHERE (FirstName LIKE ? OR LastName LIKE ?)
ORDER BY
LastName LIMIT 20", [searchThis+'%', searchThis+'%'],
function(tx, result){
// success, but how do I get result to my other function?
}
, function(tx, error) {
alert('Failed to retrieve notes from database - ' +
error.message);
return;
});
});
}

[Proto-Scripty] Ajax.Responders
I seem to have a problem with my code. I won't post all of it here,
but when use this:
Ajax.Responders.register(
{
onCreate: function()
{
if($('loading') && Ajax.activeRequestCount>0)
{
Effect.Appear('loading',{duration: .5, queue: 'end'});
$('loading').update('Loading ('+Ajax.activeRequestCount
+')...');
}
},
onComplete: function()
{
if($('loading') && Ajax.activeRequestCount==0)
{
Effect.Fade('loading',{duration: .5, queue: 'end'});
$('loading').update('Loading ('+Ajax.activeRequestCount
+')...');
}
}
}
);
after the first set of Ajax calls it seems to get stuck and only
increments, does not deduct. (So my loading screen doesn't go away.)
Any ideas what I could be doing wrong? I have many Ajax calls, but
the site seems to be working as expected so I know the data did load.

[Proto-Scripty] Re: Ajax.Responders
Thanks for the optimizations. I think the problem is elsewhere
though No browser errors. I'm on the latest WebKit.

[Proto-Scripty] Re: Ajax.Responders
WebKit has a JS debugger much like Firebug, no errors. Here's the
function I call that seems to no decrement the counter:
function saveAllCEs() {
$A(document.getElementsByClassName("editable")).each(
function(ce){
new Ajax.Updater({ failure: $('evalMsgs') },
'/aa/saveHTML.html', {
parameters: { RxN: gRxN, id: ce.id, HTML: $(ce).innerHTML },
insertion: 'after', onComplete: function(){return true;} }); }
);
}

[Proto-Scripty] Re: Ajax.Responders
My error was not having the success in Ajax.Updater. I didn't want one, but it is required... Thanks!
