One Window Inspecting And Controlling Elements In Another?
Oct 4, 2010
Is it possible to have a javascript read elements from one browser tab from another? What I want to do is have a simple script that refreshes a page that I don't host every second or so and if the text on it changes from a preset string then to stop refreshing. So I have one tab open running the JS that I host which is pressing refresh repeatedly on the other tab and if that changes then it stops refreshing.
I've tried to think of a way to do this server-side (PHP) but couldn't think of one. I could make a script that reads the remote page repeatedly and if it changes then loads it, but to load it the remote page would refresh and then would probably lose the string I am after.
Even if just to say "nah, not possible" or something about XSS that I don't really understand...!

I'm trying to control a popup window from two different pages in my main window but having troubles.
My first page (bigpage1.asp) opens a popup window called 'PopCreate'. This popup window opens a frameset with two frames; 'TopFrame' and 'BottomFrame'. While 'BottomFrame' is processing some information, the top frame's page (top1.asp) refreshes to page 2 (top2.asp) after 3 seconds (using meta refresh). On page 2 (top2.asp), I want the entire popup window to close. I'm having troubles with this.
Alternatively, when the first page (bigpage1.asp) in my main window refreshes to the main second page (bigpage2.asp), the second page (bigpage2.asp) could close the popup window (PopCreate).

Is it possible for javascript to inspect the contents of an iframe or
is it an external object?
<iframe id="myiframe" src="">
<script>
document.getElementById.myiframe.src =
"http://www.wherever.com/foo.php"
</script>
I can set the src of the iframe from javascript, can I read the
results, assuming the iframe returns some text?
like with frames you can nest the document object,
mytext = document.getElementById.myiframe.document.body

As someone who has a web site, there is this popup (not my own) that comes
up that I can't make go away when others view the page. Is there anyway,
at least, to make sure that the parent window supersedes and is the top
lawyer vs. this smaller pop-up using javascript?

I have a few checkboxes in a form. Some of them work independently, but some make the others go on and off. Specifically the lower ones are controlling the upper ones.
<td>
<input type="checkbox" name="weddingitem1" value="Toppers" id="Toppers"/><label for="Toppers" >Toppers<br />
<input type="checkbox" name="weddingitem2" value="Champers" id="Champers"/><label for="Champers" >Champers<br />
</td>

In Firefox, the JavaScript code an interact with the document object to affect HTML structure and CSS style rules as well as define behaviors for given events.
Can the JavaScript code also modify elements of the window object, like menus, not just enable or disable them in a new window? If so, how?

I'm trying to achieve this: when I click on the "Zgodovina_Prikaz" div, "Zgodovina_Vsebina" div should appear, which is inside "Zgodovina_Prikazj" div.
Here's the code that works now, but I have to add the "Zgodovina_Prikaz" exactly before "Zgodovina_Vsebina" for it to work.
$(document).ready(function() {
$(".Zgodovina_Vsebina").hide();
$(".Zgodovina_Prikaz").click(function() {

I have found out that doing a window.resizeTo(w,h) does not resize the
client area tot his size, but the entire window (including tool bars etc).
So, with an address bar, a tool bar and a status bar etc showing, the
window.document.body.offsetHeight value will be ~200 points smaller than the
required size.
We have a simple set of data in a table, but it can resize based on a font
size.
On change of font from a combo we call a resize function.
How can I ensure that the body.offsetHeight and widths are enough to show
all of my table, without hard coding for toolbars etc (Because they may not
be there on some browsers.)
Is there a way like in java to *pack* the client area to best fit?

I'm trying to use unobtrusive javascript for a page I am building. I want to insert a "bookmark me" item into the page. This is the script I am using:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html xmlns="[URL]" xml:lang="en" lang="en">
<head><title>Page</title>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
<link rel="stylesheet" type="text/css" href="/css/base.css" />
<script type="text/javascript">
<!--
function add_favorite() {
document.getElementById('bookmark').innerHTML="<a href="#" rel="sidebar" onclick="if(navigator.appName=='Microsoft Internet Explorer'){ window.external.AddFavorite(location.href, document.title); return false; }else{ this.title = document.title; }" onMouseover="window.status='Bookmark Us';return true" onMouseout="window.status=";return true" title="Bookmark This Page"><img src="/images/bookmark65-3.png" alt="Bookmark This Page" /></a>";
} window.onload=add_favorite();
-->
</script></head><body>
<div id="wrapper">
<div id="header">
<h1>Heading goes here...</h1>
<div id="bookmark">
</div></div>
<div id="main">
<h2>Content goes here...</h2>
</div><div id="footer">
Footer goes here...
</div></div></body></html>
It's pretty simple stuff that just populates an empty div with an image link to bookmark the page when users have javascript enabled. Now when I call the function using <body onload="add_favorite();"> and cancel out the window.onload=add_favorite(); from the script it works just fine (it throws a line-1 syntax error up in IE that I can't figure out, but functionally everything still works in IE7 and FF2). When I try to do it the "unobtrusive" way I get nothing at all in either browser.
A little debugging revealed that the function is indeed being called and is running successfully, however the function is somehow unable to locate the element with ID of "bookmark" when it is fired with window.onload and as a result I get no bookmarking link. It's almost like window.onload is triggering itself too soon, before the div of "bookmark" is in the page, but how can that be?

<BODY onload="window.scrollTo(x,y)">
However I am linking to Google Images so I can't modify their page
code.
Is there a way to link from frame a to frame b so that the javascript
in frame a decides and controls at what position the page will load?

I want control a hardware device using a Web browser.
I created a page which has a form containing all necessary INPUTs.
By clicking a button, all current settings are sent to the server side
(using POST or GET) so that the server can interact with the hardware,
which is under the server's control.
Now, in some cases, I want to update the INPUT (w/ readonly) with the
data from the hardware, such as a status value.
Most primitive approach is creating a new page with new value to the
INPUT, where I want to show the value.
But that is not quite efficient as the page appearance won't change
except the contents of the INPUT.
As Javascript can make any change to the HTML page (at client's side)
that is currently being displayed, it is more straight forward if the
server can send a set of Javascript commands to the web server so that
it can just update the display contents rather than refreshing
everything.
I thought such scheme was already available, but so far, I don't see
anything usable.
The Web server is not a commercial one but a custom Web server
(written in Python) so that I want to keep the scheme as simple as
possible. I checked AJAX but I'm not sure I can use AJAX in my
application.

I'm using the following to allow dynamic resixing of an image (when the usre
presses down on a button):
function widthup() {
image.width = image.width + 1;
width.innerText = image.width;
if(x==1) {
setTimeout('widthup()',0);
}
}
even when the 'setTimout' is at zero it goes pretty slowly. Any way to have
something faster?

Does anyone know if it is possible to control UI tabs from an external URL, is this possible?
For example, right now, the ui-tabs-nav list of anchors correspond to the divs automatically. I would like to make the tabs' navigation controllable from a separate draggable modal or popup window so I can drag it to a second monitor and use the main screen on GoToMeeting, to switch tab panels almost like Powerpoint (but more useful.) In advance I want to preempt suggestions that I do something different entirely, like simply make the browser window span two monitors, etc. Easy idea but doesn't work; I've tried it.

I have an index.html that sets up 3 Frames. They are called FrameTop, FrameA and FrameB. See pic below. In FrameTop the user can type in a url into a textbox with id="urlINPUT". When user clicks LOADA it loads that url into FrameA. User can then browse web in FrameA, clicking links etc and going to new pages. The second button LOADB is designed to determine the current location/url of the page displayed in FrameA and load that into FrameB. So far when I write the javascript in FrameTop LOADA works but LOADB loads the FrameTop into FrameB! [error!]
-----------------Index.html-------------------------------------
<frameset rows="5%,*">
<frame name="FrameTop" src="frame_top.html" />[code].....

In a form, how do I have a set of radio buttons with the last one being an other option that shows and hides a textfield depending on if it is selected or not? I have seen how to disable the textfield if the radio button is not selected, but not how to hide it. Is this possible?

I am working on a project and want to give the users the option to scale their font sized up and down, using a javascript or javascript/CSS combo. Basially, clicking the text icon once will enlarge it (to whatever I determine) and clicking that icon again will revert it to the normal size. They will not be able to incrementally get larger with each click... just one size. Code:

I’m using the following Java Script to set the width of text fields:
<SCRIPT>
if (navigator.appName == 'Netscape') {
document.write('<INPUT type="text" name="textfield" maxlenght="30" class="forms" size=14>
');
} else {
document.write('<INPUT type="text" name="textfield" maxlenght="30" class="forms" size=30>
');
}
</SCRIPT>
How do I use that script to set the width of the text area field below?
<textarea name="textfield2" cols="50" rows="6" class="forms"> </textarea>
