Hello I am new to Weinre and I need to debug my website which seems to act strange when opened using an IOS platform.
So I am using Weinre to debug it. I installed the tool and tested it running with the demo targets in the server itself.
Now I need to add my website as a target and run it with an iphon (or ipad) and debug it with Weinre. I don't know how to add my website as a target, I cannot manually add the
<script src="http://123.456.7.89:8080/target/target-script-min.js#anonymous"></script>
script (do not have permission to manually change the page). so How can I do my debugging with Weinre?
Thanks
You can try using a bookmarklet. The main weinre server page actually has a bookmarklet in it, for itself, that you should be able to use directly, if you can figure out how to set up a bookmarklet for your device. This seems to change release-release for mobile browsers, so you might want to do a google search on "bookmarklet" and your device's name or the OS release, to see if anyone has any tips.

The Chrome dev team apparently just rolled out a new "feature" called SuppressDifferentOriginSubframeJSDialogs, which makes it so alert+confirm boxes from an iFrame on a different domain than the parent does not show up, by default: https://www.chromestatus.com/feature/5148698084376576
This means if you have an embedded form, and you relied upon the standard JavaScript alert to inform the user of errors (or a confirm to ensure they want to make a change), it now does nothing, completely destroying the UX.
Obviously we can overwrite the built-in alert and confirms with custom ones, but moving away from what is built into the browser now introduces re-designs for every UI (mobile, tablet, laptop, desktop, etc.) instead of just relying upon proven, built-in technology.
Is there a way to change this cross-domain setting, or to whitelist specific domains to override this feature? We do have access to the parent site with an external JS include file (obviously, otherwise this would be a wide-open back door).
To Disable SuppressDifferentOriginSubframeJSDialogs , which block js Dialog box pop up
If you are single users ( Windows ) :
Right click on desktop and create a shortcut
Windows will pop up a screen and ask you "type the location of the item:"....now paste those value into the textbox
"C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-features=SuppressDifferentOriginSubframeJSDialogs
Click "next" then "finish" button to create the shortcut
Now you shall see a chrome shortcut created in your desktop .Close all active Chrome instance ( if exists ) then launch the shortcut and you will found Js pop up wont block anymore.
Tips :
If you want push this fix to all your cooperate domain users , you may consider use Domain group policy to update Chrome shortcut value or use custom domain logon script logic to do so
I found a setting in the latest Chrome GPO template that creates a reg entry that will deal with this and the same reg entry placed in the Edge location also resolves the error there. (at least it worked for the problem that came up for us yesterday FWIW)
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge]
"SuppressDifferentOriginSubframeDialogs"=dword:00000000
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]
"SuppressDifferentOriginSubframeDialogs"=dword:00000000
The latest Edge GPO templates do not have the setting yet, but I imagine it's only a matter of time.
Today I tried it again with Google Chrome Version 92.0.4515.131 and it suddenly worked again. Can anyone confirm this?
Add for Mac users.
If you use mac OS:
Quit all running instances of Chrome.
Run the terminal application.
In the terminal, run the command:
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --disable-features="SuppressDifferentOriginSubframeJSDialogs"

This question is related to my earlier question How to Debug Javascript in IOS Action App Extension. Basically, I am developing an mobile safari extension, and part of the work is to develop a javascript (operating on top of "document" provided by mobile safari) to run inside the app extension.
However, I have not found a way to debug a javascript file inside an app extension. Now, I am trying to ask the question a bit differently - given mobile safari on a page, can I somehow run an external javascript on that page and debug this external javascript? I suppose that Safari Web Inspector could help with that? Thanks.
(This is a slightly customized answer from your other question)
The official documentation for this is [here][1].
It's not too hard, although recently I've had an issue with the page showing up when connected to the iOS simulator. In that case I just ended up using my phone directly. (Apparently you need to start desktop Safari after the iOS Simulator has started to inspect "remote" Simulator sessions)
Ensure that on the device Settings->Safari->Advanced->Web Inspector is on.
(Make sure you've Trusted the computer from the device)
Start MobileSafari on your device.
Start Safari on your desktop, make sure Show Develop menu in menu bar is on in Preferences.
In the Develop menu you will see your device name, say 'BSharer's iPhone'.
select the page name underneath your device name, say 'en.m.wikipedia.org - Wikipedia'.
You are now debugging that device's page on your desktop. The developer page will open and you can debug as if it was running on the desktop machine. You should now see all the JavaScript that is available to that page and set breakpoints.
(The app extension requires the debugger; statement because we don't see the javascript files injected by the app extension. You can still use the debugger statement but it's not usually necessary.)
I have a typical modern web-app, regularly shared on Twitter.
I recently noticed that, when opening our web-app in the Twitter internal browser, localstorage is deactivated, which breaks our app.
How could I break out of the Twitter internal browser and open the page in the default Android browser?
I haven't tried this but just a suggestion. You could take a look at this and give it a try.
At the end of the article, it says that the external app won't be invoked if triggered without a user gesture but I believe that the limitation won't be there in case of the In-App browser.
Well, I think it isn't quite easy to say Android via a WebView to open the Chrome Browser as this in-app browser could be a lot different.
What you could try, as mentioned in the article Here is to trigger a click on an anchor which is calling an "pseudo" intent and add the fallback_url .
There isn't much details provided but it could be a possible hack / workaround.
In your HTML
...
And with JS:
$(".open_me").trigger("click");
According to the article
Now the URL will get you to zxing.org if the app could not be found, or the link was triggered from JavaScript without user gesture
(or for other cases where we don’t launch an external application.)
If you're lucky it will open the fallback_url, but as mentioned before it is a WebView which isn't the same as the Chrome Browser, therefore it is possible that nothing happens.
You can use a iFrame in your HTML like this:
<iframe src="url.com" width="900" height=400"></iframe>
I have seen several posts that talk about remote debugging of javascript code on Android, but they all miss the point of what I am trying to do.
I have a Nexus 7 and I want to use it as a remote development environment when I am away from my desktop. I have created a chrooted debian distribution to run apache and php and git (via ssh). This chrooted environment mounts a subdirectory of the /sdcard directory from outside the chroot environement. Apache document root of a virtual host is pointing at a directory within this. Before leaving the desktop I can git push the latest release to the tablet. When I return git pull can get what I have done back again.
I then (when away from home and NOT connected to any network) can edit the code using an Android editor (using the 920 text editor), but then run the browser to look at what I have developed using localhost the apache virtual host picks this up and displays it.
The application I am developing IS NOT FOR ANDROID - it is ultimately for the desktop. But I want to be able to debug it like I was on the desktop. Breakpoints and single stepping are the prime thing, but also I tend to use the html section in firebug to adjust my CSS before editing it.
Is there a way to get either the chrome developer tools or firebug add on for firefox to load into a browser that will run in android?
I use Firebug lite bookmarklet for iPhone and iPad, never tried on Android, check this out http://martinkool.com/post/13629963755/firebug-on-ipad-and-iphone it must be similar on Android.
To activate it use this steps:
Create a new bookmark or bookmark a page
Rename the bookmark to “Firebug”
Copy the textarea link:
javascript:(function(F,i,r,e,b,u,g,L,I,T,E){if(F.getElementById(b))return;E=F[i+'NS']&&F.documentElement.namespaceURI;E=E?Fi+'NS':Fi;Er;Er;Er;(Fe[0]||Fe[0]).appendChild(E);E=new%20Image;Er;})(document,'createElement','setAttribute','getElementsByTagName','FirebugLite','4','firebug-lite.js','releases/lite/latest/skin/xp/sprite.png','https://getfirebug.com/','#startOpened');
Edit the Firebug bookmarklet, remove the URL and paste the
bookmarklet
Choose “Done” (on the virtual keyboard) and you’re all set
Hitting that bookmarklet should give you a fully functioning Firebug at the bottom of your mobile device.
At least not for Firefox Mobile, because all the devtools are still partially based on XUL, where the Firefox Mobile is using Native UI.
I don't think there is any plan in the close future to change this situation; it's not a common scenario.
However, you should be able to do something using the Debugger API, creating an add-on for Firefox Mobile. But I don't know if it's worthy.
We are using Google Apps at our company and everyone has Chrome installed on their computers. The problem is that we still have to use IE for certain things. I have a few html files on our intranet site that link to Google Docs, but it's opening in an IE browser. I need it to open a Chrome browser so the user doesn't have to sign in each time they open the file. I only have control of the html files settings so is there any way to use Javascript to force a window to open in Chrome?
Thanks!
I believe that if you're using IE you can use ActiveX to open up specific programs.
For instance try looking at 'new ActiveXObject'
You must explicitly allow this however as IE confirms if you want to allow it to be executed.
function loadProg(path){
var active = new ActiveXObject("WScript.Shell");
activeX = active.Run(path);
}
If you know the direct file path use this like
loadProg(path);
More specifically like
window.onload = function(){
loadProg("\"C:\\Program Files (x86)\\Guitar Pro 5\\GP5.exe\"");
};
I don't know the path to Chrome so i used something else instead.
Check if current browser is chrome:
var is_chrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1;
if not, alert user to show a message.
Are you asking if you can open a Chrome window from Javascript in an IE window? If so, then no, this is not possible. Javascript code in browsers run within a very strict sandbox that would not permit you to make any system calls. Opening a Chrome window from IE would effectively require you to execute chrome.exe on the client's machine. I'm sure you can see how this ability, if granted, could be misused to execute malicious exe's on the client' system.
I am quite sure that the best you can do using JavaScript is show a message to the user and tell them to open the file in Chrome instead. JavaScript does not have the right to execute an external application such as Chrome. See http://www.w3schools.com/js/js_browser.asp for information about detecting the browser using JavaScript.
