Help to translate the content of this tutorial to your language! Most modern browsers are configured to open new tabs instead of separate windows. Popups exist from really ancient times.

The initial idea was to show another content without closing the main window. So, popups is not something we use everyday. Still, there are tasks where popups are still used, e.

In the past, evil sites abused popups a lot. A bad page could open tons of popup windows with ads. So now most browsers try to block popups and protect the user. Most browsers block popups if they are called outside of user-triggered event handlers like onclick. This way users are somewhat protected from unwanted popups, but the functionality is not disabled totally. What if the popup opens from onclickbut after setTimeout?

So the first one is blocked, and the second one is not. There is also a number of less supported browser-specific features, which are usually not used. Check window. Run it and see what really happens.

jQuery Popup Overlay

The open call returns a reference to the new window. Please note: immediately after window. So we wait for onload to modify it. Otherwise, e. For the details, see chapter Cross-window communication. It is null for all windows except popups. So the connection between the windows is bidirectional: the main window and the popup have a reference to each other. Technically, the close method is available for any windowbut window.

The closed property is true if the window is closed. A user can close it anytime, and our code should take that possibility into account. To prevent abuse, the browser usually blocks these methods. They only work reliably on popups that we opened, that have no additional tabs.

JavaScript has no way to minify or maximize a window. These OS-level functions are hidden from Frontend-developers. We already talked about scrolling a window in the chapter Window sizes and scrolling. Theoretically, there are window. When a user attempts to switch out of the window blurit brings it back to focus.The site in general is mostly perfectly OK, but one of the links I use all the time doesn't behave in a usable way.

The link on the main page is:. I can re size the window, but not enough to view all the contents. I am migrating from the Opera browser and in Opera, when I use the embedded link it does open a new window but does have the scroll bars present. Is this a Firefox issue, or maybe the site is the source of this problem - I couldn't guess which.

I have looked through a bunch of FF options, but so far haven't found anything that could be relevant to the problem. IMO, that website is setting the size of that popup windows too small, not leaving enough room for the page content when the viewer zooms the page in. You can disable that feature using this preference in about:config. Changing dom.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note : This will cause you to lose any Extensions and some Preferences. Further information can be found in the Refresh Firefox - reset add-ons and settings article. Hi Thanks for reply. I would be surprised if a reset does fix it, as I have only been using Firefox for 2 days. In any case, I will give it a go.

Hi I have tried disabling ALL of the extensions but the above problem was not effected in any way by that. Do you still feel the Reset is the way to go? Just to add something. As well as no scroll bars, I should also have said that scroll wheel doesn't scroll the content either.

I have contacted the BBC technical department and reported the issue but I don't hold my breath waiting for an answer.

It is better not to increase the minimum font size, but to use an extension to set the default page zoom to prevent issues with text not being displayed properly. With the faulty window, the zoom still works, but of course, is of no use to see all of the page in a readable way. Just to mention. I notice that the pop-up is in fact a second instance of Firefox as opposed to an embedded window in the first instance.

Does that have any bearing on things? Firefox runs only one "instance" for all windows and tabs that are open - i.I'm using the following to open a popup that I'll use for a 'help' dialog. But I'd like the popup to expand in height automatically and be scrollable. I'm not figuring out how to accomplish this feature. Any help will be appreciated. I'd like to limit the scrolling to be just within the dialog.

Why Is My Popup Not Scrolling Properly/Background Scrolling

I need the bookmark to scroll return the dialog back to the top. But instead the bookmark just scrolls the main page. What is the syntax I need to use to scroll up or down really within just the dialog? Is there a way to have the dialog always open scrolled to the top? You can post now and register later.

Sign In Sign Up.Learn Development at Frontend Masters. You open a modal, scroll through it, close it, and wind up somewhere else on the page than you were when you opened the modal.

Sometimes this is a non-issue, like screens that are the exact height of the viewport. The width of the viewport is expanded about 15 pixels more, which is exactly the with of the scroll bar. Note that the modal needs to be shorter than the height of the viewport to make this work. Otherwise, the scroll bar on the body will be necessary. This solution works pretty great on desktop as well as Android Mobile.

That said, Safari for iOS needs a little more love because the body still scrolls when a modal is open when tapping and moving about the touchscreen. Works now! The body will not respond when the screen is touched. We can use JavaScript to avoid the touch event bubble. We all know there should be a backdrop layer when a modal is open. Unfortunately, stopPropagation is a little awkward with touch in iOS.

But preventDefault works well. That means we have to add event listeners in every DOM node contained in the modal — not just on the backdrop or the modal box layer. Oh, and one more thing: What if we need scrolling inside the modal? We still have to trigger a response for a touch event, but when reaching the top or bottom of the modal, we still need to prevent bubbling.

If we know the top of the scroll location and add it to our CSS, then the body will not scroll back to the top of the screen, so problem solved. We can use JavaScript for this by calculating the scroll top, and add that value to the body styles:. Specifically, it appears that the page already loses its scroll position when the modal is open and the body set to be fixed.

So we have to retrieve the location. That does it! The body no longer scrolls when a modal is open and the scroll location is maintained both when the modal is open and when it is closed. Frontend Masters is the best place to get it. Create a position: fixed; overflow: auto; overlay that expands to the window edge, and put the modal box inside that overlay.

No mention of overscroll-behavior: contain? Unfortunately overscroll-behavior: contain does not prevent the scrolling when the content is less or equal to the parent as in, no overflow.

If that would be possible or fixed in browsers? You just need to also set overflow: auto on the same element, or do any of a number of things that turn that element into a scrolling container. Thanks for sharing this article, Brad! Genuinely grateful for that. Weirdly, on some projects this seems to perform between with a transform: translateY I know transform: translateY Do you mean that? Genuine question: can you not just set overflow: hidden on the html element rather than the body and eliminate this issue completely?

There is a list of features for a product on the page, these are about a quarter down the page. Once you click on the a feature, one of your popups opens.

These popups are quite small. From the popup screen, you are able to scroll up and down revealing the content below the page of features whilst the popup with the overlay, sits on top. Depending on how you set those settings depends on what CSS scroll functionality is applied.

By default if they are both off Overlay Enabledthen the popup should work exactly like you want, when you close it you should be exactly where you left off. Sounds like either CSS is not working as expected due to an outside rule causing unwanted effects or possibly a JS error. Last thing it could possibly by is that your footer.

That is not typical. I will do a screencast tomorrow to show what it should do and debug while I am at it, though this is the only report of it not working as expected.
