I use a imacros.
However , I do not want to use the code of imacros.
I use a javascript file.
Is an application of the web browser using the imacros.
I want to wait for the reading to imacros.
I wrote the src of the following
window.console.log("start");
window.location.href = 'https://google.com/';
function addlisteners(){
window.alert("read the end");
}
window.onload = addlisteners;
[Alert] will not be displayed.
window.onload does not work with iMacros. You will need to use SET !WAITPAGECOMPLETE YES to achieve this effect.

Alternatively, you could use Selenium rather than iMacros which supports muc

How do i set up a custom protocol handler in chrome? Something like:
myprotocol://testfile
I would need this to send a request to http://example.com?query=testfile, then send the httpresponse to my extension.
The following method registers an application to a URI Scheme. So, you can use mycustproto: in your HTML code to trigger a local application. It works on a Google Chrome Version 51.0.2704.79 m (64-bit).
I mainly used this method for printing document silently without the print dialog popping up. The result is pretty good and is a seamless solution to integrate the external application with the browser.
HTML code (simple):
Click Me
HTML code (alternative):
<input id="DealerName" />
<button id="PrintBtn"></button>
$('#PrintBtn').on('click', function(event){
event.preventDefault();
window.location.href = 'mycustproto:dealer ' + $('#DealerName').val();
});
URI Scheme will look like this:
You can create the URI Scheme manually in registry, or run the "mycustproto.reg" file (see below).
HKEY_CURRENT_USER\Software\Classes
mycustproto
(Default) = "URL:MyCustProto Protocol"
URL Protocol = ""
DefaultIcon
(Default) = "myprogram.exe,1"
shell
open
command
(Default) = "C:\Program Files\MyProgram\myprogram.exe" "%1"
mycustproto.reg example:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Classes\mycustproto]
"URL Protocol"="\"\""
#="\"URL:MyCustProto Protocol\""
[HKEY_CURRENT_USER\Software\Classes\mycustproto\DefaultIcon]
#="\"mycustproto.exe,1\""
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell]
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell\open]
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell\open\command]
#="\"C:\\Program Files\\MyProgram\\myprogram.exe\" \"%1\""
C# console application - myprogram.exe:
using System;
using System.Collections.Generic;
using System.Text;
namespace myprogram
{
class Program
{
static string ProcessInput(string s)
{
// TODO Verify and validate the input
// string as appropriate for your application.
return s;
}
static void Main(string[] args)
{
Console.WriteLine("Raw command-line: \n\t" + Environment.CommandLine);
Console.WriteLine("\n\nArguments:\n");
foreach (string s in args)
{
Console.WriteLine("\t" + ProcessInput(s));
}
Console.WriteLine("\nPress any key to continue...");
Console.ReadKey();
}
}
}
Try to run the program first to make sure the program has been placed in the correct path:
cmd> "C:\Program Files\MyProgram\myprogram.exe" "mycustproto:Hello World"
Click the link on your HTML page:
You will see a warning window popup for the first time.
To reset the external protocol handler setting in Chrome:
If you have ever accepted the custom protocol in Chrome and would like to reset the setting, do this (currently, there is no UI in Chrome to change the setting):
Edit "Local State" this file under this path:
C:\Users\Username\AppData\Local\Google\Chrome\User Data\
or Simply go to:
%USERPROFILE%\AppData\Local\Google\Chrome\User Data\
Then, search for this string: protocol_handler
You will see the custom protocol from there.
Note: Please close your Google Chrome before editing the file. Otherwise, the change you have made will be overwritten by Chrome.
Reference:
https://msdn.microsoft.com/en-us/library/aa767914(v=vs.85).aspx
Chrome 13 now supports the navigator.registerProtocolHandler API. For example,
navigator.registerProtocolHandler(
'web+custom', 'http://example.com/rph?q=%s', 'My App');
Note that your protocol name has to start with web+, with a few exceptions for common ones (like mailto, etc). For more details, see: http://updates.html5rocks.com/2011/06/Registering-a-custom-protocol-handler
This question is old now, but there's been a recent update to Chrome (at least where packaged apps are concerned)...
http://developer.chrome.com/apps/manifest/url_handlers
and
https://github.com/GoogleChrome/chrome-extensions-samples/blob/e716678b67fd30a5876a552b9665e9f847d6d84b/apps/samples/url-handler/README.md
It allows you to register a handler for a URL (as long as you own it). Sadly no myprotocol:// but at least you can do http://myprotocol.mysite.com and can create a webpage there that points people to the app in the app store.
This is how I did it. Your app would need to install a few reg keys on installation, then in any browser you can just link to foo:\anythingHere.txt and it will open your app and pass it that value.
This is not my code, just something I found on the web when searching the same question. Just change all "foo" in the text below to the protocol name you want and change the path to your exe as well.
(put this in to a text file as save as foo.reg on your desktop, then double click it to install the keys)
-----Below this line goes into the .reg file (NOT including this line)------
REGEDIT4
[HKEY_CLASSES_ROOT\foo]
#="URL:foo Protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\foo\shell]
[HKEY_CLASSES_ROOT\foo\shell\open]
[HKEY_CLASSES_ROOT\foo\shell\open\command]
#="\"C:\\Program Files (x86)\\Notepad++\\notepad++.exe\" \"%1\""
Not sure whether this is the right place for my answer, but as I found very few helpful threads and this was one of them, I am posting my solution here.
Problem: I wanted Linux Mint 19.2 Cinnamon to open Evolution when clicking on mailto links in Chromium. Gmail was registered as default handler in chrome://settings/handlers and I could not choose any other handler.
Solution:
Use the xdg-settings in the console
xdg-settings set default-url-scheme-handler mailto org.gnome.Evolution.desktop
Solution was found here https://alt.os.linux.ubuntu.narkive.com/U3Gy7inF/kubuntu-mailto-links-in-chrome-doesn-t-open-evolution and adapted for my case.
I've found the solution by Jun Hsieh and MuffinMan generally works when it comes to clicking links on pages in Chrome or pasting into the URL bar, but it doesn't seem to work in a specific case of passing the string on the command line.
For example, both of the following commands open a blank Chrome window which then does nothing.
"c:\Program Files (x86)\Google\Chrome\Application\chrome.exe" "foo://C:/test.txt"
"c:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --new-window "foo://C:/test.txt"
For comparison, feeding Chrome an http or https URL with either of these commands causes the web page to be opened.
This became apparent because one of our customers reported that clicking links for our product from a PDF being displayed within Adobe Reader fails to invoke our product when Chrome is the default browser. (It works fine with MSIE and Firefox as default, but not when either Chrome or Edge are default.)
I'm guessing that instead of just telling Windows to invoke the URL and letting Windows figure things out, the Adobe product is finding the default browser, which is Chrome in this case, and then passing the URL on the command line.
I'd be interested if anyone knows of Chrome security or other settings which might be relevant here so that Chrome will fully handle a protocol handler, even if it's provided via the command line. I've been looking but so far haven't found anything.
I've been testing this against Chrome 88.0.4324.182.
open
C:\Users\<Username>\AppData\Local\Google\Chrome\User Data\Default
open Preferences then search for excluded_schemes you will find it in 'protocol_handler' delete this excluded scheme(s) to reset chrome to open url with default application
I'm using the QT WebEngine framework to display web pages. I'm injecting javascript into a page when it loads, and want to allow the javascript to be able to access a QT object. Apparently, to do this a QWebChannel must exist that establishes some IPC between chromium (the javascript) and the rest of my C++/QT project. I came across the QWebEnginePage::setWebChannel (QWebChannel *channel) function, however I can't find any examples of its use. The documentation (http://doc.qt.io/qt-5/qwebenginepage.html#setWebChannel) mentions that qt.webChannelTransport should be available in the javascript context, but I don't see where that is established in qwebchannel.js (https://github.com/qtproject/qtwebchannel/blob/dev/src/webchannel/qwebchannel.js). I've seen the WebChannel examples (http://doc.qt.io/qt-5/qtwebchannel-examples.html) and would like to avoid WebSockets if possible.
Below is how I tried to implement the web channel.
Whenever a page loads I establish a channel and inject the javascript in C++:
QWebChannel *channel = new QWebChannel();
channel->registerObject(QStringLiteral("jshelper"), helper);
view->page()->runJavaScript(qwebjs); //this is qwebchannel.js
view->page()->setWebChannel(channel);
view->page()->runJavaScript(myfunction); //function that calls QT object (jshelper)
In Javascript:
new QWebChannel(qt.webChannelTransport, function(channel) { ... });
Which results in the channel not being connected properly (assuming this is because of qt.webChannelTransport, as it was working when I was using WebSockets). Any pointers to examples of QWebChannel being set up with QWebEnginePage this way is also appreciated.
Short answer: add <script type="text/javascript" src="qrc:///qtwebchannel/qwebchannel.js"></script> to your html page (before you call new QWebChannel of course), and remove the line view->page()->runJavaScript(qwebjs); //this is qwebchannel.js from your C++ code.
Long answer:
I too had a ton of trouble figuring out how to use QWebChannel without WebSockets correctly -- managed to get it working after digging around in Qt 5.5 source code and mailing lists (documentation is still lacking). Note that this only works with the new Qt 5.5.
Here's how to use QWebChannel:
// file: MyWebEngineView.cpp, MyWebEngineView extends QWebEngineView
QWebChannel *channel = new QWebChannel(page());
// set the web channel to be used by the page
// see http://doc.qt.io/qt-5/qwebenginepage.html#setWebChannel
page()->setWebChannel(channel);
// register QObjects to be exposed to JavaScript
channel->registerObject(QStringLiteral("jshelper"), helper);
// now you can call page()->runJavaScript(...) etc
// you DON'T need to call runJavaScript with qwebchannel.js, see the html file below
// load your page
load(url);
And on the JS side:
<!-- NOTE: this is what you're missing -->
<script type="text/javascript" src="qrc:///qtwebchannel/qwebchannel.js"></script>
<script type="text/javascript">
<!-- it's a good idea to initialize webchannel after DOM ready, if your code is going to manipulate the DOM -->
document.addEventListener("DOMContentLoaded", function () {
new QWebChannel(qt.webChannelTransport, function (channel) {
var jshelper = channel.objects.jshelper;
// do what you gotta do
});
});
</script>
Also make sure you've added QT += webenginewidgets webchannel to your .pro file else this won't build!
Bonus: you can debug your JavaScript from the comfort of Chrome Dev Tools now! Just add this somewhere in your Qt code (ideally in your application startup):
#ifdef QT_DEBUG
qputenv("QTWEBENGINE_REMOTE_DEBUGGING", "23654");
#endif
Then start your application, navigate to http://localhost:23654 in Chrome, and you'll get a fully-functional JS debugger, profiler, console, etc :)
Follow-up (19/04/2016): if your remote debugger isn't working, note that the qputenv call must also occur before any calls to QWebEngineSettings or any other WebEngine-related class, because these trigger the WebEngine "zygote" process immediately (the zygote is the parent QtWebEngineProcess from which all future QtWebEngineProcesses are forked) and then qputenv cannot affect it. Spent a few hours tracking this down.
Recently Qt introduced the QtWebEngine module. Is there a way to invoke developer tools and debug JavaScript code inside QWebEngineView? It was possible with QWebView using
page()->settings()->setAttribute(QWebSettings::DeveloperExtrasEnabled, true);
but I couldn't find any similar option in QWebEngineView.
I just ran across this so I added it here for posterity.
It was just added to Qt 5.5 git. You have to enable it via an environment variable QTWEBENGINE_REMOTE_DEBUGGING=<port>. You can put 0.0.0.0:<port> if you are doing debugging of an embedded device and cant use the local console. Then you can point can connect to http://127.0.0.1: to get the debugger. It will need to be a chromium based browser. Do you have to use Chrome, or you can actually use the "quick nano browser" example if you want.
Alternatively, one may embed Firebug Lite to get a JavaScript console and inspectors.
Just add
<script type="text/javascript" src="https://getfirebug.com/firebug-lite.js"></script>
into the page. Pressing F12 will visualize the Firebug console.
If your devtools view and page are in the same program，use qt function to directly navigate to page devtools instead of http://localhost:port whith is devtools index(have to select devtools of whitch page).
After QTWEBENGINE_REMOTE_DEBUGGING being set up
>=5.13:
void QWebEnginePage::setDevToolsPage(QWebEnginePage *devToolsPage)
5.11~5.12:
void QWebEnginePage::setInspectedPage(QWebEnginePage *page)
Sample pyqt5.12
dev_view = QWebEngineView() # new web view
self.page().setDevToolsPage(dev_view.page()) # self is the source web view
Reference:
https://doc.qt.io/qt-5/qwebenginepage.html#setDevToolsPage
https://doc.qt.io/qt-5/qwebenginepage.html#setInspectedPage
For PyQt5 the following snippet:
self.mainLayout = QtWidgets.QVBoxLayout()
self.webView = QtWebEngineWidgets.QWebEngineView()
self.mainLayout.addWidget(self.webView, 100)
self.webView.settings().setAttribute(QtWebEngineWidgets.QWebEngineSettings.JavascriptEnabled, True)
self.webView.settings().setAttribute(QtWebEngineWidgets.QWebEngineSettings.LocalContentCanAccessRemoteUrls, True)
self.webView.settings().setAttribute(QtWebEngineWidgets.QWebEngineSettings.ErrorPageEnabled, True)
self.webView.settings().setAttribute(QtWebEngineWidgets.QWebEngineSettings.PluginsEnabled, True)
dev_view = QtWebEngineWidgets.QWebEngineView()
self.mainLayout.addWidget(dev_view, 100)
self.webView.page().setDevToolsPage(dev_view.page())
From http://blog.qt.io/blog/2015/03/17/qt-5-5-alpha-available/:
The remote inspector can be used by either defining the env variable
QTWEBENGINE_REMOTE_DEBUGGING, or by supplying the
–remote-debugging-port command line argument. You can then point a
browser at the specified port and inspect your web content.
look this：
The Chromium DevTools provide the ability to inspect and debug layout and performance issues of any web content

I am running RStudio on a server and I created a RMarkdown (.Rmd) file. It works fine if I create it as a static HTML but it does not work if I want it to be interactive (by adding runtime:shiny).
The issue is that when I add runtime:shiny and press the Run Document button the application will try to open at 127.0.0.1:xxxx (here xxxx is a random port). In order to make it work I would have to be able to change the host parameter to '0.0.0.0'. This is an option in the runApp function from the shiny package but I don't know how to add this option in RMarkdown.
Can anyone help me with this?
Thank you.
The ::run command from rmarkdown invokes shiny::runApp internally. You can set the option shiny.host before running the document:
options(shiny.host="0.0.0.0")
rmarkdown::run("myfile.Rmd")
You an also pass arbitrary paramters to runApp, so this should work too:
rmarkdown::run("myfile.Rmd", shiny_args=list(host="0.0.0.0"))
Neither of these will work with the Run Document button; that button starts a new R session in which to render the document. To change the shiny.host option in that session, you'll need to add the option to your .Rprofile.
Set the default values you want to initialize in (~/.Rprofile) under user directory
Sys.setenv(TZ = "UTC") # for Timezone
options(shiny.port = 9999)
I currently store text to speech mp3 files as varbinary(max) in the database. what I want to do is play those audio files using the embed tag where the source is ashx file that will recieve the id of the database record and write the byte array.
My ashx file has the following code
byte[] byteArray = ttsMessage.MessageContents;
context.Response.Buffer = true;
context.Response.Clear();
context.Response.ClearContent();
context.Response.ClearHeaders();
context.Response.ContentType = "audio/mpeg";
context.Response.OutputStream.Write(byteArray, 0, byteArray.Length);
context.Response.End();
The call from the aspx page is as follows
Panel5.Controls.Add(new LiteralControl(String.Format("<embed src='/TestArea/PreviewWav.ashx?source={0}' type='audio/mpeg' height='60px' width='144px'/>", ttsMessage.Id.ToString())));
I have gotten this to work with the following
Panel5.Controls.Add(new LiteralControl(String.Format("<audio controls='controls' autoplay='autoplay'><source src='/TestArea/PreviewWav.ashx?source={0}' type='audio/x-wav' /></audio>", ttsMessage.Id.ToString())));
Using the audio tag but cannot seem to get it to work with the embed tag.
I am using IE9/VS2010
Any ideas?
I think the wrong thing with embed tag is that...
Embed tag call a plugin like winmediaplayer ocx than handler firstly called from web page than media plugin get the ashx url than it started to call handler.
But web page's request and mediaplayer plugin's requests are diffent so if you check users Authentication or some other header information it fails.
You can easily see that on fiddler utility. On fiddler top-right side shows the request info. there is a user-agent part. Look it carefully.
How many requests happen from your handler,notice them. What are the differs. for each reqs.
If you have this issue,
You may use a ticket system or redirect a safety area for download without header or other request checks. Sadly web page requst cannot complately transfer media player and others.
hope helps
