More on the window. How can I bring back the window if it is minimized or behind another window? How do I force a maximized window?
How do I turn off window resizability or remove toolbars? How do I resize a window to fit its content? How do I know whether a window I opened is still open? How can I tell when my window was blocked by a popup blocker?
What is the JavaScript relationship between the main window and the secondary window? I cannot access the properties of the new secondary window. Why is that? Most modern browsers offers a popup-blocking feature. Users can be using browser-built-in feature or extensions include opening a link in a new window or not, in the same window, in a new tab or not, in «background» or not.
Coding carelessly to open new windows can no longer be assured of success, cannot succeed by force and, if it does, it will annoy a majority of users. New windows can have menubar missing, scrollbars missing, status bar missing, window resizability disabled, etc. Therefore, tab-browsing is preferred by a lot of users because the normal user-interface of the browser window they prefer is kept intact, remains stable.
Opening new tabs is less demanding on the user’s system resources and faster to achieve than opening new windows. Several corporations allow their employees to surf on the web but under strict security policies: no JavaScript enabled, no Java, no ActiveX, no Flash.

Opening New Browser Windows, Jakob Nielsen, May When extreme changes in context are explicitly identified before they occur, then the users can determine if they wish to proceed or so they can be prepared for the change: not only they will not be confused or feel disoriented, but more experienced users can better decide how to open such links in a new window or not, in the same window, in a new tab or not, in «background» or not.

HTML Standard dom-open-dev. Uncheck your camera and then check it again. See if the video starts working. The next simple fix to try is to restart the Zoom app. Sometimes stopping and restarting an app will work. Does your device have all the latest system updates? If not, update them now. Once you are sure your device is up to date, check your Zoom app. First, determine if the cause of your problem is your camera or the Zoom app itself. If it works on another application, the problem is with the Zoom app.
The reverse is also true. Your device may be blocking access to your camera. To verify that the Zoom app has camera permission settings on Windows 10, start by typing Settings into the search bar. The first section allows access to your camera on your device. SVG is supported on most browsers. I found this article enormously helpful. Huge thanks to yonran. I wanted to pass on some additional learning I found while implementing some of the techniques he provided. In FF6 and Chrome 9, support for media queries from JS was added, which can greatly simplify the media query approach necessary for determining zoom in FF.
See the docs at MDN here. For my purposes, I only needed to detect whether the browser was zoomed in or out, I had no need for the actual zoom factor. I was able to get my answer with one line of JavaScript:.
I have a solution for this as of Jan The principle is as follows. Collect 2 MouseEvent points that are far apart. Each mouse event comes with screen and document coordinates. Measure the distance between the 2 points in both coordinate systems. Although there are variable fixed offsets between the coordinate systems due to the browser furniture, the distance between the points should be identical if the page is not zoomed.
The reason for specifying «far apart» I put this as 12 pixels is so that small zoom changes e. Only do the distance calculations rarely, e. Limitations: Assumes user will move the mouse at least a little, and zoom is unknowable until this time. It is standard and works both on desktop and mobile: browser support.
If you need to detect zoom level that might be a sign of bad UI design. On mobile devices with Chrome for Android or Opera Mobile you can detect zoom by window. Detect on Safari: document.
Your calculations are still based on a number of CSS pixels. They’re just a different size on the screen now. That’s the point of full page zoom. What would you want to happen on a browser on a dpi device which therefore normally displayed four device pixels for each pixel in an image?
This is for Chrome , in the wake of user answer But this approach has limitations : for example if you play the accordion with the application window rapidly enlarge and reduce the width of the window then you will get gaps between zoom levels although the zoom has not changed may be outerWidth and innerWidth are not exactly updated in the same time. If you want the zoom level right after the pinch move, you will probably have to set a little timeout because of the rendering delay but I’m not sure because I didn’t test it.
This answer is based on comments about devicePixelRatio coming back incorrectly on user’s answer. I found that this command was coming back incorrectly in some instances too when working with a desktop, Surface Pro 3, and Surface Pro 4. What I found is that it worked on my desktop, but the SP3 and SP4 were giving different numbers from each other and the desktop. I noticed though that the SP3 was coming back as 1 and a half times the zoom level I was expecting.
So, the solution to the comments should be to divide the returned zoom level by the scale of the machine you are currently on. Have it currently working however still need to separate by browser.
Tested successfully on Chrome 75 and Safari It also gets the zoom value correct on retina display and calculations are triggered on resize event. Zoom factor and scale are not to be confused with each other. Users control «zoom»; «scale» is a CSS transformation. This does that. I use it in conjunction with media queries to detect in JavaScript device scaling, i. I used a different approach, i created a dom element with a fixed height and width of px, position fixed and opacity of 0, basically a hidden element.
From my page I had to link to JQuery and this file to get it work, even though my master page already had a link to JQuery. This is question was posted like ages back, but today when i was looking for the same answer «How to detect zoom in and out event», i couldn’t find one answer that would fit all the browsers.
This can be captured using:. The problem lies in the types of monitor used, a 4k monitor vs standard monitor. Chrome is by far the smartest at being able to tell us what the zoom level is just by using window. Other browsers, not so much. IE and Edge are probably the worst, as they handle zoom levels much differently. As of May , here’s what I have to detect zoom levels for a few of the most popular browsers, Chrome, Firefox, and IE I have it tell me what the zoom percentage is.
If anyone would care to take a stab at other browsers and update the fiddle, then please do so. Stack Overflow for Teams — Start collaborating and sharing organizational knowledge.
