Prototype.__defineGetter__() Equivalent In Konqueror
Jul 20, 2005
Is there an equivalent in Konqueror's KJS engine to Gecko's
__defineGetter__() and __defineSetter__() methods? Our web application
uses a ton of Javascript, written based on Internet Explorer's object
model as that's the primary platform that we're supporting. For
Netscape support we uses __defineGetter__() and __defineSetter__() to
emulate the many IE-only properties. I've tested our site using
Safari, and to my surprise, it renders perfectly. Alas, it's
completely non-functional. If it's somehow possible, I'd love to write
a similar emulation library for KJS so that our non-Windows users
would have an alternative to crummy Netscape/Mozilla.

I discover a strange bug in Konqueror 3.1.1.
I design a javascript application which acts in one file called
example.html. At the beggining of this js i write:
if (document.images)
{
folderopen= new Image(16,16);
folderopen.src="http://www.sergioamo.8m.com/buttons/folder_open.png";
folderclose= new Image(16,16);
folderclose.src="http://www.sergioamo.8m.com/buttons/folder_close.png";
}
functions....
....
...
..
and my javascript works perfect.
If i write:
if (document.images)
{
folderopen= new Image(16,16);
folderopen.src="./buttons/folder_open.png";
folderclose= new Image(16,16);
folderclose.src="./buttons/folder_close.png";
}
functions...
....
...
..
my javascript does not work properly. Does anyone knows if is imposible
to use relative references with konqueror 3.1.1 or which is the problem?

I am creating a chat script that uses PHP and Javascript. For part of it I need to empty one of the text boxes. The scripts I use work fine in IE and Firefox, however the the text box will not clear in Opera and Konqueror. I have tried the follwoing:
document.getElementById('commentbox').innerHTML = ''
and
document.chatform.comment.value = "";
Like I said they are both fine in IE and Firefox, but not in Konqueror or Opera. I have searched for hours looking for code that will work.

I am trying to capture the image coordinates when a user clicks on an
image. My code is working in Firefox, Mozilla, Netscape, IE, and
Opera, but fails under Konqueror (and I suspect Safari). The code below
fails in Konqueror when the page is scrolled down; the coordinates are
off by the scroll amount.
My code in the html img tag: onClick="MLDot(event)"
and the related statements in the MLDot function:
xPosition =
event.offsetX?(event.offsetX):event.pageX-document.getElementById("clickImage").offsetLeft;
yPosition =
event.offsetY?(event.offsetY):event.pageY-document.getElementById("clickImage").offsetTop;
Anyone know how to pick up image coordinates in Konqueror/Safari?

I have a Web page with two frames.
The left frame has a DHTML-generated tree of links (to images). The
right frame displays the image link you click in the tree of links.
It works great on all browsers except Konqueror/Safari, where it
displays the first image link you click on in the tree of links. But
then subsequent clicks on other links do nothing.
That is, the first time you click on a DHTML-generated link,
Konqueror/Safari loads the corresponding image in the other frame.
However, after that, when you click on links, the other frame is not
updated.
Do you know why this happens?

According to ECMAScript, the root of the prototype chain is Object.Prototype. Each object has an internal property [[Prototype]] that could be another object or NULL.... However, it also says that every function has the Function prototype object: Function.Prototype, it confused me, because a function is an object, for a function object, what is its function prototype and object prototype..For example:
var x = function (n) {return n+1;};
what is the relationships of x, Object.Prototype and Function.Prototype

I am trying to get to the bottom of javascript object, prototypes etc. I have a fairly good grasp of it, but I get confused the closer I get to the base object.prototype. FIrst of all, I was under the impression that all objects descend directly from Object. But some objects (like Array) seem to inherit properties and methods from the function.prototype. So does this mean that the chain is like this:
object -- function -- array Second, I noticed (on the mozilla javascript reference site that object.prototype inherits properties and methods from function.prototype and vice versa!? How can this be? I must be missing something important about understanding the chain?

Is there a way to achieve multithreading in JavaScript? I'm looking to
fetch a page into a div while allowing the user to interact with another
div. At some point the newly fetched page contents will be available to the
div that the user is working in but I don't want to cause unnecessary
blocking. I've thought of using frames (would prefer divs) plus timeouts
and checking for when a load completes. Does anyone have an idea of how
this could work?

A friend of mine has built as simple site for use on his company's
intranet. It uses JavaScript to read comma-delimited information from a
text file and displays it in tabular form.
When I looked at the source there is js like this:
function forwardClick() {
if (sitelist.recordset.AbsolutePosition !=
sitelist.recordset.RecordCount) {
sitelist.recordset.moveNext();
} else {
alert("You are already at the last record in the database.");
}}
and HTML like this:
<OBJECT id="sitelist"
classid="clsid:333C7BC4-460F-11D0-BC04-0080C7055A83" border="0"
width="0" height="0">
<PARAM name="DataURL" value="sites.txt">
<PARAM name="UseHeader" value="True">
</OBJECT>
Obviously it's a Windows and IE only thing but is there an equivalent
for non-IE browsers and/or non-Windows OS?

wondering if there is a va_list equivalent in Javascript. Well,
actually, I know that there is, but I don't know if its user...
applicable. va_list in C/++ anyhow is a way of being able to pass in
any number of arguments at the end of a function, I'll show an example:
Code: ( text )
Header:void addLine(int, const char*, ...); cpp:addLine(int line, const char *string, ...) {char *output;va_list args;va_start(args, string);vasprintf(&output, string, args);va_end(args);}
So as you can see, the space is reserved at the end of the function
declaration with the "..." syntax, and in the function body is expanded
and processed. I could be way off here, but I think I'm on the right
track.

I'm trying to find out if javascript has something akin to $$ in php.What I'm trying to do:
var costs = {
cost1: 5,
cost2: 10,
cost3: 15
}
// Retrieve cost user has selected
alert(costs.selectedCost);
Its obviously a hyper-simplified example of what I'm trying to do, but the premise is the same. In PHP, I could use $$ to convert one variable into another, not sure if JS can do the same.

I've been using display:none on the style property of some <option>
elements in my forms, which works fine with Mozilla - as expected it
removes the option from my dropdown (although it still exists in the
code). Is there an equivalent in IE?
The reasoning behind this is that I want users to rank objects using a
<select> for each place (see below), and to remove the choice of earlier
objects from <select> drop-downs later in the list.
1st place: [<Select> with option 2 chosen]
2nd place: [<select> with option 4 chosen]
3rd place: [<select> --> Option 1
Option 3
Option 5
Option n]

Mozilla-equivalent of the following line of code:
document.getElementById('editorContent').contentWindow.event.srcElement.href
The purpose of this line is to get the "href" value of a link when clicked on inside a content-editable iframe.I have the function working perfectly in IE, but not having much luck with Mozilla browsers.

Whats the Javascript equivalent for PHP's file_get_contents ?
<script type="text/javascript">
document.open("http://anotherpage.php"); // I know this is not the way because this opens a new page

Any way without using frames ?

<html><head>
<script src="jquery.js"></script>
<script type="text/javascript">
addIframe = function() {
$('body').append('<iframe>');
} appendIframe = function() {
$('iframe').contents().find('body').append('appended');}
</script>
</head><body>
<button onClick="javascript:addIframe();">addIframe</button>
<button onClick="javascript:appendIframe();">appendIframe</button>
</body></html>
Now this work perfectly fine with jQ 1.6.2, but does not work with 1.4.2 because 1.4.2 does not yet know .find(element).
