[Proto-Scripty] Re: Using store with options and IE7
Hi,
The `Option` constructor is provided by the browser and returns an
HTMLOptionElement instance; since IE6 and IE7 don't allow prototypical
extensions to these things[1], you have to run it through `$` (or
`Element.extend`) to extend the element:
function optionAdder(s) {
var optIdx = $('mySelect').options.length;
$('mySelect').options[optIdx] = $(new Option(s.text, s.val)); // <==
Change is here
$('mySelect').options[optIdx].store("meta", s.meta);
}
In contrast to `Option`, the `Element` constructor is provided by
Prototype and does this for you automatically.

[Proto-Scripty] Re: PeriodicalExecuter
Hi,
All you need to do is make sure you have a reference to the PE, so you
can call its stop function. The PE will pass a reference to itself
into the function it's calling, so you can do this with arguments. Or
you can just keep a reference to the PE when you create it, and later
use that reference to stop it.
Option 1: Use the argument the PE passes you:
* * * *
// No need for the extra wrapper function, the PE can call `checkAll`
directly
// and doing so gives us access to the argument
//WAS: new PeriodicalExecuter(function() { checkAll() },30);
new PeriodicalExecuter(checkAll, 30);
// `checkAll` now gets the PE instance as an argument
//WAS: function checkAll(){
function checkAll(pe){
for (i=1; i<=6; i++){
// pass it on to `check`
check(i, pe);
}
}
// `check` now receives the PE instance as an argument
//WAS: function check(num){
function check(num, pe){
$('jetway0'+num).value ='...';
$('jetway0'+num).style.color='black';
new Ajax.Request("http://someIP:80"+num+"/somefile.jsp";, {
onSuccess: function(transport) {
if (transport.status == 200) {
$('jetway0'+num).value ='Up';
$('jetway0'+num).style.color='green';
}else{
$('jetway0'+num).value ='Code: '+transport.status;
$('jetway0'+num).style.color='olive';
}
},
onFailure: function(){
$('jetway0'+num).value='Down';
$('jetway0'+num).style.color='red';
// Stop the PE
pe.stop();
}
});
}
* * * *
Option 2: Remember a reference when you create it (I wouldn't create a
new global variable, though, which is what this does if all of this is
at the top level of the file):
* * * *
// Remember a reference to the PE we're creating
//WAS: new PeriodicalExecuter(function() { checkAll() },30);
var theAjaxPE = new PeriodicalExecuter(function() { checkAll() },30);
// Or, again, there's no need for that wrapper function, could be:
//var theAjaxPE = new PeriodicalExecuter(checkAll, 30);
function checkAll(){
for (i=1; i<=6; i++){
check(i);
}
}
function check(num){
$('jetway0'+num).value ='...';
$('jetway0'+num).style.color='black';
new Ajax.Request("http://someIP:80"+num+"/somefile.jsp";, {
onSuccess: function(transport) {
if (transport.status == 200) {
$('jetway0'+num).value ='Up';
$('jetway0'+num).style.color='green';
}else{
$('jetway0'+num).value ='Code: '+transport.status;
$('jetway0'+num).style.color='olive';
}
},
onFailure: function(){
$('jetway0'+num).value='Down';
$('jetway0'+num).style.color='red';
// Stop the PE
theAjaxPE.stop();
}
});
}

[Proto-Scripty] script.aculo.us Ajax AutoComplete - making it slide up...
Hi All,
I've recently had to figure out how to make the Scriptaculous
AutoComplete functionality make it's selection box appear above the
input. It's not a very elegant solution so was wondering if anyone had
created a nicer one.
Basically I've hacked the controls.js file..
1) I set a JS variable 'upDirection' to true on the page where the
Autocompleter needs to slide up.
2) in controls.js I've changed it in two places...
in baseInitialize after the line
update.style.position = 'absolute';
// New Bit Start
if (directionUp)
{
Position.clone(element, update, {
setHeight: false,
offsetLeft: -2,
offsetTop: (0 - update.getDimensions().height)
});
}
else
{
Position.clone(element, update, {
setHeight: false,
offsetTop: element.offsetHeight
});
}
// New Bit End
}
and a similiar change in updateChoices: after the child node IF
statement...
} else {
this.entryCount = 0;
}
// New Bit Start
this.update.style.position = 'absolute';
if (directionUp)
{
Position.clone(this.element, this.update, {
setHeight: false,
offsetLeft: -2,
offsetTop: (0 - this.update.getDimensions().height)
});
}
else
{
Position.clone(this.element, this.update, {
setHeight: false,
offsetTop: this.element.offsetHeight
});
}
Effect.Appear(this.update,{duration:0.15});
// New Bit End.
this.stopIndicator();
this.update.scrollTop = 0; // RP - Part 3 of window jump fix
this.index = 0;
Has someone thought of a better way to do this? Perhaps one not
involving hacking the changes.js
file?
Cheers
Sukh

RE: [Proto-Scripty] Ajax in IE7 vs. IE8
The code posted is all the code there is. It is a simple little script
to check that it can access a specific page on several servers. The
servers are behind a load balancer using port forwarding hence the port
requirement. Port 801 goes to server1 and port 802 goes to server2 and
so on. The code works great in IE8 and Firefox 3.6.3 but not IE7. If I
remove the port it works in IE7 but all 6 requests are now checking a
random server since port 80 using a round robin to split request amongst
servers.

[Proto-Scripty] Using store with options and IE7
Whilst flogging the horse that should be dead (IE7); I discovered that
I was unable to use Element.store on the options within a select:
function optionAdder(s) {
var optIdx = $('mySelect').options.length;
$('mySelect').options[optIdx] = new Option(s.text, s.val);
$('mySelect').options[optIdx].store("meta", s.meta); //<
Object doesn't support this property or method
}
The above function works in IE8. This next function, on the other
hand, does work in IE7:
function optionAdder(s) {
$('mySelect').appendChild(new Element('option', {"value":s.val,
"meta":s.meta}).update(s.text));
}
In this case I use readAttribute instead of the retrieve method. Can
anyone offer insight as to why store doesn't work?

[Proto-Scripty] Re: How can I access an element from outside iframe
You can create a js function in the parent file, something like
function myOpacity(){ new Effect.Opacity('element ID', { from: 1,
to: 0.4, duration: 0.7});}
when you need the opacity to execute, just call the function from de
iframe this way
parent.myOpacity();
hope this helps.

[Proto-Scripty] Re: How can I access an element from outside iframe
I think I solved the problem ... not sure yet ... Yesterday I compressed prototype.js using bananascript. I think it did something wrong inside the source code. Now it seems ok in Google Chrome also... at lease until now. -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.

[Proto-Scripty] Re: Blur, Focus, Event Delegation
Hi, as I said in this ticket, you can use this code: http://gist.github.com/162593 for bubbling focus/blur. I have been using it for months and never have a single problem with this approach :) -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.

[Proto-Scripty] Re: How can I access an element from outside iframe
I did what you told me ... it's working perfectly in Safari 4 and IE8,
but ...
in GoogleChrome i get the following message in the console "Uncaught
TypeError: Object [object HTMLDivElement] has no method 'getOpacity'".
- error in effects.js:line 357 ( "from: this.element.getOpacity() ||
0.0," ). If i modify this to "this.element.style.opacity" it's
working perfectly ...
in prototype.js GetOpacity method is defined "
...
getStyle: function(element, style) {
element = $(element);
style = style == 'float' ? 'cssFloat' : style.camelize();
var value = element.style[style];
if (!value || value == 'auto') {
var css = document.defaultView.getComputedStyle(element, null);
value = css ? css[style] : null;
}
if (style == 'opacity') return value ? parseFloat(value) : 1.0;
return value == 'auto' ? null : value;
},
getOpacity: function(element) {
return $(element).getStyle('opacity');
},
"
so ... is seems to me there is a problem with prototype.js and google
chrome ... am I right ?
