I was using CodeSandbox to test JavaScript codes in my browser fast. And tried hard to get the key to switch tabs, but I couldn't. I tried Ctrl+Tab But it would rather switch the browser tabs.
So what is the hotkey to switch tabs? if there is no direct key, what is the workaround?
By default you can switch between tabs on Mac using option + command + left or right arrows or on PC using windows key + alt + left or right arrows.
Another option is to use control + number (1, 2, etc) to pick the tab in the corresponding order.
Your browser may have a keyboard shortcut associated with those combos. In my case I can do any of the commands in Safari, but Firefox switches browser tabs with the first combo I shared, so I just use the second option to pick individual tabs.
You can change your keyboard shortcuts by clicking the hamburger menu in the top left, going to file -> preferences -> keyboard shortcuts.
It actually works with Ctrl+Tab
You would only have to make the page Fullscreen in the browser, using F11
Is there a way that i can force google chrome on my pc to open my web project in a mobile view port automatically
I thought changing the meta tag of the view port in my DOM would get the job done.
If you only want to take a look of your project in mobile view, you would simply just use the DevTools (F12) and then click the Toggle device Toolbar (Top left Conner icon) or Ctrl + Shift + M to mobile view.
I'm just moved to windows 10.
And have latest version of Google Chrome on it.
But whenever I tried to access developer’s tool it shows nothing.
I have tried,
1) Right Click + Inspect element.
2) F12.
3) Right corner tab on Google chrome + more tools + developers tool.
But none of them working.
Please help.....
I don't know what is missing.
I had the same issue but in my scenario I was on a Virtual Machine with some complex display settings. The procedure here worked for me in other contexts:
You should see the process in the Windows bar on the bottom of your screen.
When you click on it, nothing is shown.
Bring back in the viewport
If the conditions above apply, then the window is simply displayed out of the display viewport. TO bring it back, do the following:
Make sure you have selected the window in the Windows bar.
Hit ALT + SPACE to show the menu
Select "Maximize".
The window should appear in one of your monitors.
Drag it around and resize it.
You should try also Ctrl+Shift+I for windows as written on the following doc
https://developers.google.com/web/tools/chrome-devtools/
I fixed this of this way
Open chrome dev tools
using the chrome page that you need debug press Win + "<" (left arrow)
windows ask you which window you want to the right and select chrome dev tool icon, but click should be in the icon instead of the rectangle of the windows
Just had the same problem. The window is apparently minimized.
On windows, hold the mouse on the chrome icon in the taskbar, when the thumb shows up, right click on it and select maximize window.
First thing i would try is closing all processes and restarting Chrome and if that doesn't work i would uninstall and reinstall chrome
I know this isn't really an answer but hope it might help
Goodluck!
Chrome -> Setting -> Extensions (Side Menu) -> Turn on Developer Mode
Had the same issue, The thing is just minimized. Hover over the side of the options at the bottom and drag to top and you will see the options.
see following image and hover over ht area highlighted in yellow
Your dev-tool might be on your second monitor, which you are not looking at but connect with your PC.
Disclaimer: Please try this at your own risk, I'm not fully aware of its consequences. It apparently clears chrome's local storage for all websites
All the solutions I saw didn't work for me, but this one did:
I deleted this folder:
// AppData\Local\Google\Chrome\User Data\Default\Local Storage\leveldb
If you enter a command in Chrome Dev tools (which could be one big block of code) and hit enter, is there a way to "undo" changes made to the DOM? Or do you simply have to refresh the page?
I too was looking for an answer to this question beyond "refresh the page"... Stumbled across this solution:
Enter Chrome dev tools (CMD + Shift + I on Mac)
Click the three dots aligned vertically to get the settings menu
Hover over "More Tools" then go to "Changes"
On the changes window you can see all the changes made during your current DOM editing session - to revert them all, simply click the
undo arrow in the bottom left...
See the visual below
Reset all changes made in Chrome dev tools
Depends on what that code actually does. For example if you change something in the style (css) or structure (html), if you refresh it will show the original page. But if that code changes a cookie value, refreshing is not enough, or even closing the browser and opening again.
I am trying to debug the features of a website when users disable their JavaScript. I was wondering how do you disable JavaScript for a page from the Google Chrome DevTools?
Click the gear icon in the corner of the Developer Tools, click Settings, then under Debugger, check Disable Javascript, as shown in the following video:
Update August 2020
Developer Tools (F12)
Click the Gear icon
Should open the Preference tab
Disable Javascript option is on the far right
Original answer
Developer Tools (F12)
Three vertical dots in upper right
Settings
Under the "Preferences" tab on the left
There will be a "Debugger" section with the option (probably on far right)
Official documentation: Disable JavaScript With Chrome DevTools
There's now a command menu built into DevTools that makes it easier to disable JavaScript. This has been around as of April 2016 or so.
Open DevTools.
Press Command+Shift+P (Mac) or Control+Shift+P (Windows, Linux) to open the Command Menu. Make sure that your cursor's focus is on the DevTools window, not your browser viewport.
Type Disable JavaScript (or some version of that... it's a fuzzy search) and then press Enter.
Use the Enable JavaScript command when you want to turn it back on.
chrome://settings/content Javascript/Manage Exceptions
This extension makes it faster (I am the author) : Quick Javascript Switcher
It is open source: https://github.com/maximelebreton/quick-javascript-switcher
You can also run Chrome with JavaScript disabled by default by using the flag:
-disable-javascript
You would use this for example by running Chrome like this:
C:\Documents and Settings\%username%\Local Settings\Application Data\Google\Chrome" -disable-javascript
The quickest way is problably this one:
F12 to open the dev console
ctrl + shift + p to open the command tool (windows)
Type 'disable javascript' and hit enter
On OSX, I had to click the triple vertical dots, and uncheck a box in the settings section. Which can also be opened with f1
Using only the keyboard at least for Windows 10:
F12, shows Developer Tools
F1, shows Settings
tab, moves to the "Disable Javascript" check box
space, toggles the option
esc, hides Settings
The fast way:
1) just click on CTRL + SHIFT + P
2) fill the field by the 3 letters dis and will appear this box and select the item Disable Javascript
.
that's all folks!
On Mac OS X:
Preferences
Show advanced settings
Press the "content settings" button
Scroll to the "JavaScript" section
Check the checkbox in front of "Do not allow any site to run JavaScript"
The Chrome Quick JavaScript Switcher extension is a lot easier though :-)
Go to options (Windows: three vertical dots in the top right) -> Settings, or hit F1.
In the General section you find "disable JavaScript"
The gear icon is no longer part of developer tools. Since Chome 30.0 it is not even possible to bring it back (In Google Chrome Developer Tools, the toolbar icons disappeared. What gives?)
To temporarily block JavaScript on a domain :
Click on the Button left to the address on the address bar (which says View site information)
In the drop-down next to JavaScript, select Always block on this site
Reload Page
Click the ⋮ menu in the corner of the Developer Tools, click Settings
Click on Advanced at the bottom
Click on Content Settings
Click on JavaScript
Switch off
Full and fast instructions for Chrome browsers (Opera incl.)
The first way
If Developer Tools aren't open then press F12 key on keyboard to show the Developer Tools. In Opera browser you have to use key combination Ctrl + Shift + i on keyboard to open it.
To show the settings just press F1 key on keyboard. The Developer Tools window must be focused when you are doing it. Or if you want to open the settings with the mouse then you have to click on ⋮ button in the top right corner of the Developer Tools, then click Settings in the menu.
Then you have to scroll down the settings window to bottom and then you will see the checkbox for disabling JavaScript like follows:
Just click on this checkbox and push esc key on keyboard for hide the settings. If you want to enable it then you have to do the same way again.
The second way
If Developer Tools aren't open then open it like in the first way is described.
Press the key combination Ctrl + Shift + P (for Windows or Linux) or Cmd (⌘) + Shift + P (for Mac) to open the Command Menu. Be sure that the focus is on the DevTools window.
Type there "Disable JavaScript" and then press Enter or click it with the mouse. If you want to turn back the enanled JS then open the Command Menu again and type there "Enable JavaScript" and then press Enter or click it with the mouse. You could also write just only "JavaScript" or "Java" there and then choose it with the mouse.
If all this does not work
For some reason it is possible that it does not work. I this case open a new empty site in "Incognito Mode" and do all this there.
The quickest way
In Chrome Web Store or on Opera Addon site you can find and install extensions which do it per one click. Just search "Javascript Switcher":
For Chrome browser
For Opera browser
Press F8 for temporarily freezing / unfreezing JS (with DevTools open).
This is very useful for debugging UI issues on elements that may lose focus if you click or press anything outside of that element. (Chrome 71.0.3578.98, Ubuntu 18.10)
Paste it: chrome://settings/content
Go to "Javascript" section and disable it.
Chrome://chrome/settings/Privacy/Content settings/JavaScript
and there you can PASTE your website's URL in Manage exceptions.. and change the JavaScript priority from ALLOW to BLOCK.
This is the latest setting for the windows
Settings > Advanced > Privacy and security > Site Settings > Javascript > Blocked then get switch on and off
good question, i try so many way, but it is curry and boring, until i find shortcut.
alt + cmd + i, this open dev tools, unless you use pocket, that need set other shortcut.
shift + cmd + p, then input: javascript
only two shortcut, but i think safari is more convenient for that.
There's a settings in chrome
open the menu from chrome,
click settings > type in "javascript" in the search bar > click site settings > click javascript.
from here you can toggle javascript specifically to a site using their url.
or just click the big button to allow/block it to all sites.
I arrived here simply wanting to know how to disable javascript in chrome:
Right click on the website
Click "inspect"
Hit keys: ctrl + shift + p
Type: "Java"
Click "disable JavaScript"
Refresh page
It's from here
