I was playing with a webapplication page developed by me using selenium.
Using selenium JavaScriptExecutor I executed following script.
executor.executeScript("return window.innerWidth");
executor.executeScript("return window.innerHeight");
to my surprise, the so called viewport size came different from Chrome, IE & Firefox.
Chrome: 1366x667
IE: 1366x667
Firefox: 1366x657
Then I realized that for body and main div, right next to body I gave css style width and height as 100% which in turn effects the view port size. As different borwsers are having different size of toolbars and menu, this 100% value changes when actual page is rendered.
So I used window.resizeTo(w,h) for setting a common viewport size. But I realized it doesn't work with modern browsers until and unless window is opened by the same script.
So I used selenium's
driver.manage().window().setSize(new Dimension(w,h));
yet I am not able to set the common view port size.
Please help to find, is it possible to set common viewport size using selenium?
Do let me know, if you need anymore info.
I executed following line for all browsers:
driver.manage().window().getSize();
Answer I got is 1382x744
So I believe this about the overall browser window, not only rendering area.
And I got confused that based on the difference of innerWidth how to calculate the browser window's new size?
PS: I have all the browsers upgraded to latest version (IE is version 11 as I am on windows 7), selenium version I am using is 2.46.x
"to my surprise, the so called viewport size came different from Chrome, IE & Firefox."
It should not be surprising that the view port size is different on all browsers, Safari even has a different one as well. When you are calling window.innerHeight it only counts the browsers inner content. So anything outside of it is not counted, the area where you enter your URL is entered is not counted for example. So each browser uses a different amount of maximum height by their tabs, and Global address bar.
When you use driver.manage().window().setSize(new Dimension(w,h)); and set it to 1920x1080 for example then all browsers will be set to that size, but of course they will have different inner height being used.
If you want the entire browser to render as 1920x1080 then I would suggest with
using Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_F11);
Thread.sleep(250);
robot.keyRelease(KeyEvent.VK_F11);
but I would advise against it, since a more valid test is to use the normal inner height of the browser, since most user do not press F11 and view their content at full screen.

I want to determine the viewport height with $window.innerHeight or document.documentElement.clientHeight but it turns out that Firefox and Chrome are returning different values (a few pixels).
Anyone already faced this issue?
The height of the body is determined by the available height inside the browser window.
Different browsers have different graphic interfaces, varying toolbar heights, number of toolbars, etc. All those elements will influence the height available for the actual HTML content.
Try the following in various browsers (in full size)
console.log(document.documentElement.clientHeight)
The height you are getting is more that likely because the design of firefox and chrome are different by a few pixels. I can resize my browser to however I want. Monitor and resolution also determines that. Not really an issue if you are designing your UI correctly, meaning using media queries in CSS and creating a responsive design instead of fixed values.
I'm sure this is the working as intended, but I find it kind of a pain.
In Chrome (and probably other browsers)
Generally, window.innerHeight gives me 801 (for example).
If I have a console open along the bottom half of my screen (going horizontally), this changes my window.innerHeight. If I've downloaded something, this pops up a bar at the bottom of the window and also changes window.innerHeight.
I don't having the dev tools open to make my site feel broken.
Is there a different measurement to use in javascript to ignore UI?
I don't want outerWidth, because this includes window tab heights and they won't be consistent cross browser.
I essentially want the height to be consistent whether or not there are any chrome ui elements present.
I don't think you can get exactly that number! The closest you can get is calculating the available height, minus os taskbar and such by using:
window.screen.availHeight
Which MDN says:
Returns the amount of vertical space available to the window on the
screen.
I made a jsfiddle to try it in here

How to make the window full screen with Javascript (stretching all over the screen)

Hy all,
I need a javascript code, that when my site loads, automatically load it into full screen mode, as if i was pressing F11, and i have my reasons to do that..So anyone knows the right code to do that?
I also need to prevent the user from changing the screen size of the page
There is a full screen API, but it is currently an early draft and browser support is very weak.
Foisting full screen mode on anyone who visits your site is one of the more hostile things you can do as a web author. You should seek an alternative design that solves whatever problem you have without doing that.
Unfortunately, there is no perfect way to get the browser to come up in full screen mode. However, you can use the screen object to determine the screen size, and set your window size appropiately. The useful screen properties are availWidth and availHeight or width and height. You can then use those to set the window object properties, either innerWidth and innerHeight or outerWidth and outerHeight. I suggest you play around with retrieving and setting these properties. Also, different browsers behave slightly differently, so, if possible, I suggest you try your code on IE (which (surprise!) is the least standard), Firefox, Safari, and Chrome.
I know the "purists" will tell you forcing a certain window size is not a good thing to do. But in some cases it is appropriate. I have written an application related to the card game bridge, and, if the browser comes up too small, the card images are unreadable. So, the first time a user accessses my web page, I make it as large as I can. Most people leave it that size. But, if they reduce the size, I store the dimensions in a cookie, and the next time they go to my page, it remembers how big to make the page. I have received many compliments on using this approach.
I am trying to make some javascript that will automatically resize an iframe based on the height of the content in the iframe.
This from QuirksMode, implies that I can use clientHeight. I am getting it this way: var innerHeight = ele.contentWindow.document.documentElement.clientHeight, and then setting ele.height = innerHeight.
On desktop Chrome this works perfectly and will make the iframe exactly fit the content. However on the default android 2.2 webbrowser, the iframe is not tall enough and some content from the bottom of the iframe is cropped. I've also tested it on iPhone (3 I think), and it behaves the same as the Android
Is there a better way to automatically adjust the height of the iframe to fit the content?
I am not sure of the exact code to use in this context, but Android has a great resource for best practices for developing for the mobile web here:
http://developer.android.com/guide/webapps/best-practices.html
and this may also help:
http://developer.android.com/guide/webapps/targeting.html
and of course it would be remiss to read what the W3C has to say here:

I know it's not like handing over code, but at least it's a start.
it it possible to resize the browser window width to fit 2 monitors through JavaScript ?
Let's say we have 2 monitors with same resolutions : 1280x760.
is it possible to expand the width of the browser to fit 2 monitor? that 1280 X 1280.
thanks.
Firstly: Don't do this! Your users will hate you for it.
Secondly, there are a number of possible configurations possible for users who have more than one monitor.
Some users will have them set to be treated as a single extra-large display; others will have them working more independantly of each other. A colleague of mine has a display-splitter hardware which means that although he has two monitors, the PC only sees one, so when he maximizes his windows, they cover both screens. My set up on the other hand is different; when I maximize, the window expands to fill a single monitor.
Some users will even have different monitor sizes and different resolutions betweeen their monitors. I know one person who has one monitor in landscape mode, and the other rotated 90 degrees in portrait mode.
A lot of these things will make it phyically impossible to have a window that is maximized across all monitors, so even if you could make it work for some users, it wouldn't work for everyone.
Assuming you do manage to get the browser window stretched across both monitors, you now have the problem of working out how to layout your page without your text and graphics being split by the edges of the monitors. Your browser won't know where the monitor edges are, so you could easily end up with important parts of your page content being broken in half which could make your site virtually unreadable.
Even if you know in advance exactly what the user's screen resolution is going to be, you still have this problem because you don't know what the user's browser window looks like. They may have the history or bookmarks side-panels open. Their desktop settings may be different too; they may have their Windows taskbar aligned on the side of the screen rather than the bottom. None of these things are in your control, and will affect the screen space available to your browser, which in turn means you can't predict where the edges of the monitors will be even in an environment where you know the screen resolution.
In short, I don't believe it's possible, and I don't believe it's desirable. I strongly recommend not doing it.
To quote from David Flanagan, "Javascript, The Definitive Guide" (5th edition), Section 14.4.3:
"The Window object defines methods that move and resize a window. Using these methods is typically considered very poor form: the user should have exclusive control of the size and position of all windows on her desktop. Modern browsers typically have an option to prevent JavaScript from moving and resizing windows, and you shuld expect this option to be on in a sizable percentage of browsers" (emphasis added)
