Javascript Zoom Browser

[Frida Kosofsky]

Iwould say not possible in most browsers, at least not without some additional plugins. And in any case I would try to avoid relying on the browser's zoom as the implementations vary (some browsers only zoom the fonts, others zoom the images, too etc). Unless you don't care much about user experience.

If you need a more reliable zoom, then consider zooming the page fonts and images with JavaScript and CSS, or possibly on the server side. The image and layout scaling issues could be addressed this way. Of course, this requires a bit more work.

Try if this works for you. This works on FF, IE8+ and chrome. The else part applies for non-firefox browsers. Though this gives you a zoom effect, it does not actually modify the zoom value at browser level.

here is my web link recently i got the task to increase its width just like if Firefox we press Ctrl + and browser zoom level is increases is there any way to do this automatically in all browsers on page load.

Note that previous versions of this answer used transform to support more browsers. However, this shortened code appears to work for current versions of Chrome, FF, Safari and IE (as well as previous versions of IE, which have supported zoom for a long time).

So when you open it on a very big screen (tv or large monitor) it looks really ugly (because it is too much whitespace at that point). And as a user, I need every time zoom it in. My webapp is more aesthetically pleasing as well as easier to use from a sofa on tv when it is scalled up a bit on that large screen.

(recommended, harder for existing page) To use em and rem units while developing your page. That will allow changing "zoom" of the page as easy as changing font size on body.

(not-recommended, easy for existing page) To use CSS "zoom" property despite the fact that it is not a standard property. Sacrifices Firefox. Also, have some minor unexpected behavior with absolutely positioned flexboxes.

In 2022, almost browsers still block the behavior of customization the browser zoom level from code (as I read somewhere, it is stated to be a bad practice and it should be controlled by the user, not the web itself).

Although, we still can handle this by a small "hack", which just effect the view (look & feel), not changing the real browser zoom level. It may also break your layout in some situations (if responsiveness available).

StackOverflow answers paint how weird cross-browser it can be. This script from 2013 works for me in Chrome, but not at all in Safari and reports incorrectly in Firefox. Even if that script worked, it relies on user agent detection (which is not long for this world) and some incredibly weird hacks.

Did you ever find a solution to this. We have the same issue never had a client with this but they view everything at 150% OS side and it ruining our layouts .! Any way to limit it or prevent it from happening?

After spending several frustrating hours on this problem I have reluctantly come to the conclusion that it is not possible to reliably read out the zoom factor on desktop because W3C and the browser vendors worked together harmoniously to completely fuck up the viewport system. On mobile it IS possible.

First, window.visualViewport.scale gives you the zoom level in supporting browsers (Chromium-based ones + Firefox Android + Safari iOS), BUT ONLY if you use pinch-zoom. With page zoom it always stays 1, as you saw. Obviously.

1) Pick one graveyard plot as your reference element and read out its offsetWidth once.

2) Compare this value to window.innerWidth and decide whether the user has zoomed in or out enough to warrant showing or hiding the text.

3) Ideally, repeat this with every resize event. Unfortunately resize events are untrustworthy on both mobile and desktop browsers because why would you make them trustworthy? So maybe add a scroll event as well, and maybe a polling script that checks once every two seconds or so.

I have been able to detect text-zoom via JS for quite a while now: when a text-zoom happens, I add a class to the tag so that I can style the page so zoomed text is still legible. You can see a demo here:

After I realized that the event.preventDefault() has been cancelled by the browser devs, along with all the relevant books and articles on the web, I stumbled upon a couple of three.js websites that have arrived to at least some decent workarounds - if not satisfying solutions.

My guess is that they provide an HTML layer and three.js is running in the background.

When the user zooms in or out, the three.js rendering is not affected, only the HTML elements are affected.

Am I right? Are there any further hints about that kind of workaround, or other solutions?

Hi

I want to display very large area in single view and to viewing different part user had to zoom/pan the view. (power distribution grid of a city)

And if I manage some how the current web browser zoom level, I can simply hide and hide object depend on current zoom level and making cluttering/de-cluttering effect.

Is there any trick to do that?

It looks like there is now broader support for getting and setting the zoom through JS apis. I've opened a ticket to review compatibility and see if this is something we can look to add now that there's broader support across browsers (looks like mobile firefox is an exception, but seems an uncommon use case).

We simply implement zooming and panning with CSS transform and mouse events. Even BJIC creates a new container for that as a module. So at this point having this feature is useless. Instead having the scroll position and changing its position is a very good tool for us.

Scaling (zooming) the browser is a useful feature that allows you to increase or decrease the size of the content on a web page. In this article, we will explore how to use JavaScript to change the browser zoom within a specific range of window widths.

Changing the browser zoom can be beneficial when you want to optimize the display of your website on different devices and screens. For example, you may want to set a specific zoom level for medium-sized screens to improve readability and visual perception on such devices.

To change the browser zoom using JavaScript, we will use the matchMedia method, which checks the condition of the browser window width. If the condition is met, we apply the scaling to the body element. Additionally, we add a resize event handler to automatically update the scaling when the window size changes.

We call the setZoom() function once when the page is loaded to set the initial scaling. Then we add a resize event handler that calls the setZoom() function whenever the browser window size changes.

As the title indicates, I cannot access Zoom either on my browser (at zoom.us) or through the app. This issue is only on a single computer, which is hard wired into my modem, and not any other device connected to my home wifi network. Does not matter which browser is used, and I have cleared cache several times. In fact, my work even replaced the computer (it's a PC) thinking it was a hardware issue, but even with a new desktop, the issue persists.

To be clear, I cannot even *access* the website zoom.us, though oddly I can get to Zoom support, and even more oddly, can get to ZoomGov. This issue rather suddenly arose one day midday, and it's extremely frustrating. It doesn't affect any other similar app (like Teams) and when I did have the Zoom app downloaded, that wouldn't work either.

Omg its happening to me I have open a support ticket and zoom is not responding I'm just glad I'm not the only one. I can only access zoom on my phone. Its like I'm being punish this happen before this Tuesday and have not been able to get on since. Zoom claims all is peachy but its not of you have pro like I have your just screwed because you cannot get anyone live and it support ticket is just been mia to me

This is happening to me too. One computer can not access the following important websites: https:/zoom.us, https:/zoom.us/signin, Https:/zoom.us/support/download, https:/zoom.us/download#client_4meeting. I was frustrated with this so I reset windows- did not work, so I reinstalled windows 10 to start fresh, but can not download zoom or login! I used another computer to put the installer on a thumb drive and put the app on my computer but it will not accept my email and password! Also have tried what you have tried, three different browsers and cleared my cashe and accept all cookies. The next drastic step would be to reformat my hard drive and reinstall windows again- but would rather not do this B/c afraid will mess something up!!

I may have solved this problem. For this particular computer I had been connected to the internet by hardwire ethernet cable. I unplugged the ethernet and connected by WiFi and I have access to the Zoom Websites now! Not sure why this happened but I have a functional solution now!

If you have trouble starting Zoom on the desktop or web, joining a meeting, or signing in to your Zoom account, i recommend clearing cache and cookies in your device or in your browser. Clear the cache and cookies from the Google Chrome browser, then relaunching Google Chrome also fixes the issue.

I have a business scenario that am creating script using TruClient Web protocol. There are some buttons which are not visible at 100% zoom but its visible at 80% zoom. Can someone please suggest how to implement zoom out in TruClient Web protocol.

In Truclient "Evaluate JavaScript" you can only write common JS, perhaps you can try this: window.document.body.style.transform = 'scale(0.8)'; or maybe you can use the General Browser Action - resize to resize the browser window. I can only provide these ideas because I don't really understand your scenario, zoom out to 80% to make some buttons visible, like press Ctrl and scroll the mouse wheel

Even worse, the experience seems incredibly pointless. Zooming in on keyboard input doesn't seem to serve a useful purpose. After all you're not actually entering any input into the text field - you're using the pop up keyboard. If the field was too small before zooming, it would be bad UI to just display it inactively. It's likely if the input field is too small to read/view it would get fixed, but zooming into the field on input doesn't make that scenario any better. It only provides annoying behavior that doesn't even revert when input is complete. Grrrr!
