JavaScript Bracket Notation
Aug 8, 2005
I have difficulty understanding how square brackets work in JavaScript and this is causing me difficulty retrieving the values of the options of my Select controls.
My form contains many select boxes. Their names are stored in variables(in this case concat is the select control name) and I have no trouble accessing methods for the select object ie:
document.Allan.elements[concat].selectedIndex;
I would like to get the value of the selectedIndex but I am having difficulty because I don't know the right syntax. I'm looking for a statement like the one that follows but uses variables
document.form.theDay.options[2].text
Could some one help me use the right syntax?

I have created a html ncaa tournament bracket for my website in which I hold annual competitions. Recently, my competition has grown and I need a better way for users to submit their brackets. What Im looking for is a way to allow the person filling out the bracket to click on their predicted winner for each game, which will then fill out the bracket as they move through the bracket until the have predicted a national c

Is it possible to have something like the following so that 'three'
can access 'one':
var x = {
one: 1,
two: { three:this.one } // Or parent.one ?
}
If not (which I have nearly come to a conclusion on) what is the next
best way to accomplish this?

i want to update several Textboxes by reading the value of another Box. For that i use the following small script:
<form name="form1" method="POST">
<input type="text" name="xx" value ="1"
<input name="tex1" type="text" size=16 maxlength=80 value="1">
</form>
Everything works fine, but for my PHP-Script i need square brackets [
]. If i try to add them, my Script got an error:
<form name="form1" method="POST">
<input type="text" name="xx" value ="1"
<input name="tex[1]" type="text" size=16 maxlength=80 value="1">
</form>
Whats wrong?

I've started learning writing javascript objects with literal notation...
Instead of the usual syntax...
The problem is that it's hard for me to adapt procedures which I'm used to within the normal syntax for the literal notation. E.g:
Is this variable global or local? If it's local, how do I declare a variable globally? I also wonder if it is possible to bind events to objects from within the object? And if I'm correct - jQuery is coded this way, but how can they then make use of their selector:
When it is an object defined with literal notation that doesn't have a constructor?

I'm declaring a class in OLN:
Code:
The problem is that in IE, when I call myfunc() it complains with the error: Class is undefined
I'm not sure what I'm doing wrong. Class is declared in as much global scope as possible, and that shouldn't even matter in JS.

I'm trying to put a function in a object created using JSON notation. The syntax looks like this...
Code:
historySet = { ajaxRunFunction: "updatePageCopy('" + pageID + "','','" + pageName + "')"};
It works fine in FF, but in IE it calls the function updatePageCopy when it creates the object history set. I don't want to call the function when the object is created.

I have the following code:
A = {
"value": "a",
};
B = A ;
B.value = "b";
alert (A.value); // => b
I expected A.value to be "a". how can I change values of a new object, without changing the parent-object?

I have a line which looks like this in PHP:
Code:
<input id="btnCancel$folder_id" type="button" value="Cancel" onclick="swfu.$folder_id.cancelQueue();" disabled="disabled" />
and of course when output looks like this:
Code:
<input id="btnCancel111" type="button" value="Cancel" onclick="swfu.111.cancelQueue();" disabled="disabled" />
It seems that the .111. throws an expected ";" error. swfu.cancelQueue(); by itself does not.
These objects are being defined in a function which takes in the folder ID as a variable, and then builds using this line:
Code:
swfu[folderId] = new SWFUpload(settings);

I'm working on some code and am running into brick walls. I'm trying
to write out Javascript with Javascript and I've read the clj Meta FAQ
and didn't see the answer, read many similar posts (with no luck
though), and searched through the IRT.ORG Faqs
(www.irt.org/script/script.htm).
The Javascript is designed to open an popup window and then inside that
window call another script which will resize that window. There may be
another way around this but the reason I tried this approach initially
was that I wanted to call the onload handler in the popup window to
resize the image only after the image had completely loaded. I've had
some code in the primary Javascript file (showimage.js) before that
works if the image has been cached but on the first load, it doesn't
resize properly which tells me it is probably because it is trying to
resize the window based on the image size but it isn't completely known
at that point. So I removed that code and tried placing the resizing
code in the second Javascript file (resizewindow.js). BTW I've tried
other code to open a popup image and automatically size it ie Q1443 at
irt.org but that doesn't do exactly what we need.
Even if there is another way to do this with one file, I still want to
figure out why this isn't working in case I run into it in the future.
I thought what I would need to do to use document.writeln to write
Javascript would be to escape any special characters and to break
apart the script tag ie
document.writeln('</SCRIPT>');
would become
document.writeln('</SCR' + 'IPT>');
I have a HTML page and 2 Javascript files. All files are in the same
directory and have permissions set correctly.
Here are the 3 files (keep in mind wordwrap has jacked up the
formatting):
index.html
----------
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Test</title>
<SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1"
SRC="showimage.js">
</SCRIPT>
</head>
<body>
Click the house<BR>
<A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG
SRC="house1thumb.jpg"></A>
</body>
</html>
showimage.js
------------
function newWindow1(pic,sitename)
{
picWindow=window.open('','','width=25,height=25,sc rollbars=1,resizable=1');
picWindow.document.writeln('<html> <head>');
picWindow.document.writeln('<SCR' + 'IPT type="text/javascript"
LANGUAGE="JavaScript1.1" SRC="resizewindow.js"></SCR' + 'IPT>');
picWindow.document.writeln('</head>');
picWindow.document.writeln('<body onload="resizewindow();">');
picWindow.document.writeln('<img src=' + pic + '>');
picWindow.document.writeln('</body> </html>');
picWindow.document.close();
}
resizewindow.js
---------------
function resizewindow()
{
// Do resizing here.
// Right now this isn't being executed
alert("resizing window");
}
Can anyone provide some pointers as to why this javascript is failing?
I'm using IE6 on Win2k and when I click on the image to open the popup
window, it does open the window but it is white with no content and the
system immediately goes from about 4% CPU usage to 100% and
consistently stays there until I kill that window with the task
manager.

Attached is a simple HTML file that adds and delete rows. In the add
row function I set an attribute "onClick" this triggers the
testMessage() function. When I try this in Firefox it works just fine
however on IE it just refuses to work.
What is interseting is the ROW that already exists has a similar
'onClick' event which works when the page is loaded, but subsequent
"row" additions to the table to not work in IE. Code:

I'm getting errors in Firefox everytime I try to run this frame resize code, but it works fine in IE. I can't seem to figure out what the problem is with it.
The error is: Error: theFrame has no properties
Line: 8
The line that the javascript console is showing an error for is in italics.
code from page:
<html>
<head>
<script type="text/javascript">
var defaultCols="100px,*";
var hiddenCols="0px,*";
function ShowHideMenu(){
theFrame = document.getElementById("framed");
if(theFrame.cols == defaultCols) theFrame.cols=hiddenCols;
else theFrame.cols=defaultCols;
}
</script>
<frameset cols="100px,*" name="framed">
<frame src="lframe.htm" name="frameMenu">
<frame src="mframe.htm" name="content">
</frameset>
</head>
<body>
</body></html>
Come someone let me know what I'm doing wrong here?

I'm already past the basics of Javascript, and i need something that takes me to the other level and teaches me the new technologies and cool stuff (drag&drop, AJAX, OOP in javascript, maybe XUL...etc). So far i found these two books:
1. Sitepoint's "The JavaScript Anthology: 101 Essential Tips, Tricks & Hacks".
2. Worx's "Professional JavaScript for Web Developers (Wrox Professional Guides)"
Both seems to cover very insteresting topics, but i can only buy one of them. So which one do you suggest?
and by the way, i've read the sample chapter 5 of Sitepoint's book, and it seems like the author(s) just put the solutions/codes there and let you figure them out on your own. Is this how the rest of the chapters are?

This is a question about defensive web browsing. Ocassionally I run into a page whose JavaScript does something that I find obnoxious. I would like to turn off JavaScript only for that page (instead of disabling it globally). It would be cool if there were some way to do this through a "bookmarkable" JavaScript snippet using the javascript: pseudoprotocol. Does anyone know any trick to do any of this?

I am looking for a method to extract the links embedded within the
Javascript in a web page: an ActiveX component, or example code in
C++/Pascal/etc. I am looking for a general solution, not one tailored
to a particular page/script.
Hopefully, the problem can be solved without recreating a complete
Javascript interpreter. Any ideas?

I would like to know how to write javascript such that, a part of it isnt considered as script, & rather as HTML. Code:
Ok, the layer div can be written using document.write. But, Google ad itself is a javascript isnt it. How can it be written into this? How does this work?

Ok so, this is my purpose:
- to be able to load asynchronously (via AJAX) some javascript ads (like google's or adbrite) so as to make them be loaded in the background, then update the page after the ads have loaded via innerHTML
Why?
-Because 90% of the time in my newer sites, javascript ads are the major offender in terms of speed of page rendering
My problem:
Via ajax, I can call a php file that retrieves some javascript and outputs it, XMLhttprequest returns those javascript lines, but they don't render in the page, since they miss the whole page loading, and are apparently not parsed
For example, let's say I call a php file via ajax, and it returns the output into a variable named "text" containing "document.write('hello')"
if I use xxx.innerHTML=text, nothing happens
My 1st solution:
Passing those javascript lines to eval() [like eval(text) ], but this produces a second problem, that I couldn't solve (probably because of my lack of knowledge in javascipt):
if I eval the code, it deletes my current page and renders a new one
for example, if I parse a document.write, my page disappears, and a new one is rendered with the document.write text
What I want is basically to make that "document.write" appear inside a div in my page, adding to the content (and not overwriting the whole page), much like what happens when using innerHTML
Is this even possible? How would you go about it?
I tried xxx.innerHTML=eval(outputfromphpfile) but it overwrites my whole page...

Just a quickie: is it possible to place javascript within javascript? The following is the code I am using to create a pop-up for a picture gallery. I would like to place a banner from a banner exchange in bold under each photo. When I use the code below I get an error message:
<SCRIPT language=JavaScript>
<!--
function openpic(pic_name) {
myWin= open("", "displayWindow", "width=640,height=510,status=no,toolbar=no,
menubar=no,scrollbars=yes,resizable=yes,alwaysraised=yes");
myWin.document.open();
myWin.document.write("<html><head><title>" + pic_name + "</title>");
myWin.document.write("</head><BODY><center><TABLE CELLPADDING=Ɔ' CELLSPACING=Ɔ' WIDTH=òr'>");
myWin.document.write("<br><img src=kate/image"+ pic_name + ".jpg><br>");
myWin.document.write("<br><br><BR><br><BR><br><BR>");
myWin.document.write("<script language='javascript' type='text/javascript' src='http://www.linkbuddies.com/ad.go?id=134039+2&n=3'></script>");
myWin.document.write("</center></body></html>");
myWin.document.close();

Basically, on one of my sites I'm running adsense and today I added Chitika. The problem is, I can't run those type of ads through my banner advertising program.
The banner advertising program calls the banners/HTML from code like this:
<script language=JavaScript src=http://www.mysite.com/advertise/abm.asp?z=1></script>
And using that program I'm able to either choose a banner or HTML I want to display when that code above is used. It displays HTML ok... but when I try to run an ad of either adsense or chitika nothing displays on the page. The code that would be called is:
<script type="text/javascript"><!--
*Chicika code in here*
//--></script>
<script src="http://xxx/xxx/mm.js" type="text/javascript">
</script>
So... it looks like I can't have javascript call another javascript to display on a page. My question is then... how can I edit the above to make it work or how can I work around this problem? I'd really want this to work with Chitika and not so much with adsense... but it appears both Chitika and Adsense use similar javascript code.
