Open new page at specific size - html

I have rollover that when clicked opens a link (video) in a new page or tab depending on if I specify target="_blank".
Question? Can I control the width of this new (parent) page. I would like it to be ~80% smaller than the parent just to show the user that it is a separate page. Or.. How can I have this code open in a window of the existing page?
Thank you for your time
<div id="apDiv3"><img src="Rollover blankBL.png" alt="Fork at 5.7 Km stay right" width="400" height="225" id="fork 57" /></div>

As you mentioned in your own post you can use window.open read the window.open documentation for more info. You can specify many parameters about the popup. A simple popup with explicit width / height would look like this:
window.open('http://www.google.com',"My Window Name", "width=400,height=400")
I also created a plunker so you can see it in action
HOWEVER, I really advise against using this. This is the OLD way of doing things. This type of popup hasn't been popular for well over 10 years now. Outside of being annoying and unpopular it is also not dependable. Some browsers / popup blockers will totally block this window from opening.
A better alternative is to use some sort of JS modal library to load the content within the actual page (not in a new window).
One I really like is Magnific Popup they have a bunch of examples on their page.

Overlay one iframe on top of another, scroll them together

Following up on How to rewrite URLs referenced by Javascript code? I'd like to overlay a button on top of someone else's website (e.g. overlay a Paypal button alongside Stackoverflow's bounty button) and have the two <iframe>s scroll together. The button would reside in the top layer. The website would reside in the bottom layer.
I understand that transparent <iframe>s were/are abused for clickjacking but the browser security mechanism seems to block legitimate use-cases. In my case the user is seeing the same button he/she is clicking. It's even possible that this is a browser bug.
Here is what I see under Chrome:
The top <iframe> intercepts all mouse clicks, even for areas that do not contain any components. Meaning, users cannot interact with the bottom layer at all.
If I style the top <iframe> with pointer-events: none the opposite problem occurs: users are able to see the top layer but all mouse clicks go to the bottom layer. Applying pointer-events: auto to child components does not help (clicks still pass through to the bottom layer).
If I size and position the top <iframe> so its area is equal precisely to the button I am trying to overlay, then mouse clicks go to the right layer but the top layer fails to scroll alongside the bottom layer. Meaning, the button always remains in the same absolute position as the bottom layer scrolls.
Is it possible for me to position a button in the top layer so that it always aligns with a certain position in the bottom layer? In the example where I position a Paypal button alongside the Stackoverflow bounty, I expect the Paypal button to scroll off the page as the user scrolls down the question.
https://stackoverflow.com/a/4087397/14731 leads me to believe this is not possible. Is there another way to implement this?
UPDATE: Here is a jsfiddle for you to play with. The test button is found to the right of "NEWS & VIEWS" in the middle of the page.
Update: New approach
Following discussion with Gili below, the requirement for the solution to work across multiple pages made me rethink my solution.
The new approach:
Doesn't require any code changes or specific features on the target site.
Works on every page while the user navigates (as long as they stay on the same domain)
Could be tweaked to inject any HTML/JS into any DOM element within any target page
My solution works as follows:
Send the person you want to demonstrate Widget X to an email with a link to your instructions page
That instructions page contains a bookmarklet which they add to their bookmarks bar
They visit their own site and click your bookmarklet
Your bookmarklet injects javascript into their page
That javascript creates a pop-up window with content that appears to belong to the target domain, since that domain generated the popup
That pop-up window then monitors the DOM on the target browser window (window.opener) and injects our arbitrary HTML whenever the current page doesn't contain our target node ID.
It seems to work well in my testing (perfect in Chrome, haven't tested across all browsers yet) and seems to work on every target site from StackOverflow to Twitter.
Live demo here: How to demo an web widget on a third party site without having access to their code
Sample code below, expanded for readability:
s = "<script type='text/javascript'>setInterval(function() { if(!window.opener.document.getElementById('gctrlPixelator')) {var i=document.createElement('IMG');i.src='//lorempixel.com/400/200/';i.id='gctrlPixelator';i.style.cssText='top:20;right:20;position:absolute;z-index: 9999;';window.opener.document.getElementsByTagName('body')[0].appendChild(i);}},500);</script>";
t = "<div style='text-align: center; font-family: Arial, Helvetica;'><h1 style='font-size: 18px;'>Demo running!</h1> Keep this window open and return to the main site window to continue the demo.</div>";
w = window.open('','name','height=200,width=400');
w.document.write(s);
w.document.write(t);
The above should be converted into a bookmarklet before deploying to an 'instructions' landing page for a potential client.
Original solution
First, sorry for posting this as an answer rather than as a comment. I've been thinking about this for half an hour, and only just realised I need 50 reputation to comment. So, apologies, but I wanted to share...
I agree that it's unlikely there is a cross browser way to do this double iframe trick. I read your other question about javascript URL rewriting and it lead me to an idea: Rather than trying to embed/hijack their site on another URL, how about creating a bookmarklet that allows you to inject your Javascript into their page?
It could work like this:
Direct them to your site where you host the custom bookmarklet link. Ask them to add it to their favorites.
Ask them to go to their own site, then click your bookmarklet in their bookmarks.
This would inject your JS into their page, allowing you to edit the DOM any way you wanted (e.g. changing styles, adding DOM elements, etc.)
Code something like this, converted to a bookmarklet (i.e. wrapped in a function with a javascript: at the start) could do the trick...
var script = document.createElement("script");
script.setAttribute("type", "text/javascript");
script.setAttribute("src", "http://www.example.com/file.js");
document.getElementsByTagName("head")[0].appendChild(script);
I've tested that in Chrome and it seems happy to load the JS cross-domain. The only rule seems to be that the protocols must match (http or https).
Not quite what you asked for, but a possible solution.

HTML + Chrome help having a form in the page space

I am trying to create a input box somewhere on the screen in chrome, not attached to extension button like a normal popup,
it also needs to be running all the time so the user doesnt need to click the extension button to open it, for example so they do not have to come out of fullscreen.
What i have so far since im not great at html or java just a simple form
What i have: http://i.imgur.com/xCY1a41.png
What i want: http://i.imgur.com/cJH8bD4.png
I would also like to control the position of the form but from what i have above doesnt seem as if i will be able,
Sorry if its a bit vague but anything helps!
What you want to do can't be done in Chrome. This is by design. If web content could display itself outside the boundaries of the browser tab's content area, then users might be confused who was presenting it. Confusion is just the beginning of that problem: if web/extension content could masquerade as a system or browser-level alert, then that content could trick the user into doing something dangerous.
If you need a presence outside of a browser tab, your options are a native app or Chrome App.
If you want the input box to be displayed on the page you could use content script - then it would appear as you presented.

display overflow html content outside browser

This may be the dumbest question ever but our customer really wants this. I am asking this silly question just to be sure that it cannot be done.
We have a popup window which has opened by window.showModalDialog (img 1)
In this window there is a custom autocomplete control which displays an html table. The problem is autocomplete table is wider than the modal dialog. So user is unable to see the contents of this table. (img 2)
Then we made initial size of the modal dialog wider enough to see table contents but customer did not want the initial empty area and did not want the content to be wider also. (img 3)
The customer wants to see the thing as in img 4 which i could only made by paint.
Is it possible to display overflowed html content outside the browser. At least for the ones which has opened by window.showModalDialog.
Note: This is about a 10 years old project and it is totally based on window.open and window.showModailDialog. So using a custom jquery dialog or something similar is not an option.
Within your client's constraints, your task is not possible.
What you could do instead is popup another modal window that shows the contents of the dropdown. That way, you can get a differently sized viewport than what the first modal window offers. Also, if you open the new one as a child, you could even pass messages between the 2 windows.
Of course this will be a very rudimentary stone-age solution! You may also come across a lot of browser limitations/quirks.

Html popup window, the parent should have no access

I'm trying to create a popup() where user clicks on button, then it triggers window where he does some edit.
While the user is editing in the child window, parent window should not be accessed, it should be blocked.
How exactly should i do this?
This is what i'm doing now.
function Popupwindow()
{
name = "Select Requestor";
url = "selectLocation.html";
options = "height=330, width=210, location=no, scrollbars=yes,menubars=yes,toolbars=yes,resizable=yes,left=0";
window.open(url,name,options);
}
So now i'm able to close parent window and even edit parent elements without closing child window.
What you want is called a modal dialog. There's no standard way to do this across multiple browsers, some don't even have anything like it. Your best bet is creating a modal dialog inside the page. Most JS frameworks/toolkits will provide dialogs.
don't use "real" popups, use javascript to "emulate" them in teh same window. take a look at jquerys dialog, where you can also set the modal-mode (example and example) - i think this is what you want.
there are a lot of standalone-js examples out thre if you're not using jquery and a lot of js-frameworks include things like this - just search for "modal dialog".

Open a new browser window WITHOUT using target="_blank"

Every solution I've seen so far for opening a new browser window uses the target property in to set it to "_blank". This is frustrating because in some browsers it only opens a new tab AND combine that with the auto-resizing behvaiour at http://www.facebook.com/connect/prompt_feed.php?&message=test, it basically mangles my browser whenever I try updating my status from my site.
How can I be sure to open a new window when a user clicks on a link?
Thanks!

Popups are windows, they just have some features disables. You can make a popup act like a regular window by enabling these features. For example, if you open a popup with
window.open('url', 'name', 'width=500, height=500, status=1, toolbar=1, location=1, menubar=1, resizable=1');
the window will have a toolbar, a URL bar, a status bar, menus, and it will be resizable. It will the same as any other window.
Keep in mind, however, that many browsers block window.open() under some conditions, and some of them will open new tabs if you specify a lot of features. Some are weird about it too; Chrome, for example, uses scroll bars on popups by default, but if you specifically tell it to use scroll bars in a popup (using scrollbars=1), it will open in a tab instead.
So basically there is no way to be completely sure that your page will always open in a new window, because browsers all handle this stuff differently, users can change settings too. The code above is probably your best bet if you have to have a new window, but you might want to look into other options.
window.open(URL,name,specs,replace)
function newwindow()
{
myWindow=window.open('','','width=300,height=300');
myWindow.document.write("<p>This should open in a popup</p>");
myWindow.focus();
}
There is a legitimate reason for using Target=_blank that everybody has completely overlooked, and that is when a website is written as a BOOK with chapters/pages and the Table of Contents must remain intact without using the BACK button to reload the previous page (Table of Contents). This way all a surfer needs to do is close the Target Page when finished reading and they will be back to the Table of Contents.
Lucky for us that HTML5 has reinstated the Target="_blank" code, but unfortunately the "Block Popups" must be unchecked for it to work.
