I am trying to automate a site in a WPF application with WebBrowser control.
The site checks for the javascript window.name in each page and throws an error if this does not match with the preset value.
Look at the sample below.
var id="1234";
if (window.name != id)
{
window.open("home.html", id)
}
Is there a way to get this value and set it when I create a new WebBrowser object?
I tried the following and my problem is resolved. Hope this may help somebody.
I first navigated the page to a blank page with this code.
var html = string.Format(
"<html><body><h4>Opening ...</h4><script type='text/javascript'>window.open('about:blank', '{0}');</script></body></html>",
popupWindowName);
var w = new Browser();
w.NavigateToString(html);
And then in the page is load completed event, I navigated to the original URL.
w.Navigate("https://somesite.com/page.aspx",
null, null, h);
The popup window name was changed to what I wanted and the session continuted correctly. This is not a solution to the problem I faced, but it is more like a work around.
I also had to deal with the popups that kept coming. I had handled the NewWindow2 event to handle the popups.

I am new to angularjs , so this question might seems silly to experience ones , But i really not able to perform this , can any body tell me that how to come back to app from webview after reaching to specific url , Like i am opening a window in browser for payment process so what i need is that when url in webview comes up with a success msg , i want to close the webview and get back to my application , I goggled and found a way that in $window.open() we pass three parameters and through second i can do that , but don't know how to implement that , can any one provide me a way to deal that.
i studied thi link :- Tracking a child window across page loads
i tried this function too :-
if (!$window.closed){
if($window.location.href =="http://www.magentomobileshop.com/demo/index.php/payu/index/success")
{
$window.close()
}
}
Thanks
Please have a look on it :-
Close a child window in an Android app made with Angularjs
here is my updated Answer ...and I have tested it
and its working fine
var url = "test_Url";
var socialLoginWindow = window
.open(url,
'_blank',
'location=no');
// listen to page load
// events
socialLoginWindow
.addEventListener(
'loadstart',
function(
event) {
var url = event.url;
if (url == "http://www.magentomobileshop.com/demo/index.php/payu/index/success/") {
socialLoginWindow
.close();
}
});
And here is the reference link for it :-
https://forum.ionicframework.com/t/opening-external-link-and-closing-it-at-an-event/6660/9
Here "Loadstart" will track your every change of url in window.So, the current URL can be get from event.url
Cheers !!!
Happy coding.
Use $window.close() in $window service.
You can broadcast the result to another controller like this AngularJS – Communicating Between Controllers

You can use the $window.location.href to check for the particular URL to be true
I'm trying to get pdf.js to work locally on a windows phone app written in Xamarin but I can't understand why if I pass a url without any querystring it works:
url = "Assets/pdfjs/web/viewer.html"
Uri uri = new Uri(url, UriKind.Relative);
PdfWebViewer.Source = uri;
The above displays the pdf.js viewer correctly but with no pdf file of course but if I change the url to:
url = "Assets/pdfjs/web/viewer.html?file=test.pdf"
Uri uri = new Uri(url, UriKind.Relative);
PdfWebViewer.Source = uri;
I just get a page not found. Note the javascript is enabled.
I've added the various web browser events to see if I could spot anything else, and when I call the url without a querystring, it calls the Navigating event followed by the Navigated event but as soon as I specify a querystring, it triggers the Navigating followed by NavigationFailed event but I can't see the error as the exception returned in e.exception is null.
Am I missing something?? Is this not allowed?
Thanks.
UPDATE:
It may not be a problem with Xamarin as I've just tried the same thing in a WP8.1 using the WebBrowser control and I get exactly the same behaviour.
Private Sub Button_Click(sender As Object, e As RoutedEventArgs)
WebBrowser.IsScriptEnabled = True
WebBrowser.Source = New Uri("/Html/Viewer.Html?file=1", UriKind.Relative)
End Sub
My Viewer.html is the most basic page you could have:
<html>
<body>
Test
</body>
</html>
Get rid of the query string and the web browser will display Test. Any ideas??
Let's say normally my users access our web page via https://www.mycompany.com/go/mybusinessname
Inside this web page, we have a iframe which actually comes from https://www.mycompany.com/myapp
Everything is working fine, except that if for some reason, the users come to know about this url https://www.mycompany.com/myapp. They can start accessing it directly by typing into the address bar.
This is what I want to prevent them from doing. Is there any best practice to achieve this?
==== Update to provide more background ====
The parent page which is https://www.mycompany.com is the company's page and it's maintained by some other team. So they have all the generic header and footer, etc. so each application is rendered as an iframe inside it. (This also means we cannot change the parent page's code)
If users access https://www.mycompany.com/myapp directly, they won't be able to see the header and footer. Yes, it's not a big deal, but I just want to maintain the consistency.
Another of my concern is that, in our dev environment (aka when running the page locally) we don't have the parent-iframe thing. We access our page directly from http://localhost:port. Hence I want to find a solution that can allow us access it normally when running locally as well.
If such solution simple does not exist, please let me know as well :)
On your iframe's source, you can check the parent's window by using window.top.location and see if it's set to 'https://www.mycompany.com/go/mybusinessname'. If not, redirect the page.
var myUrl = 'https://www.mycompany.com/go/mybusinessname';
if(window.top.location.href !== myUrl) {
window.top.location.href = myUrl;
}
I realized we already had a function to determine whether the page in running under https://www.mycompany.com. So now I only need to do the below to perform the redirecting when our page is not iframe
var expectedPathname = "/go/mybusinessname";
var getLocation = function (href) {
var l = document.createElement("a");
l.href = href;
return l;
};
if (window == window.top) { // if not iframe
var link = getLocation(window.top.location.href);
if (link.pathname !== expectedPathname) {
link.pathname = expectedPathname;
window.top.location.replace(link.href);
}
}
You can use HTTP referer header on server-side. If the page is opened in IFRAME - the referer contains parent page address. Otherwise, it is empty or contains different page.
Now that I discovered here that I can't write JavaScript within one page to enter form data on another external page, I'd like to do this with a browser-based bookmarklet instead.
I'm able to access the data on my original page with this bookmarklet code snippet:
javascript:var%20thecode=document.myForm.myTextArea.value;
If I open the external Web-based form manually in the browser, this code changes what's in the text box:
javascript:void(document.externalForm.externalTextArea.value="HELLO WORLD"));
And this bookmarklet code will open a new browser window with the external form:
javascript:newWindow=window.open("http://www.url.com","newWindow");if(window.focus){void(newWindow.focus());}
However, when I try to put these snippets together in a single bookmarklet to open the external form in a new window and change the data inside, I can't access any of the elements in newWindow. For example, this doesn't work to check the existing value of the text area in the new window
javascript:var%20newWindow=window.open("http://www.url.com","newWindow");if(window.focus){void(newWindow.focus());}window.alert(newWindow.document.externalForm.externalTextArea.value);
Once I use the bookmarklet code to open the new window as newWindow, I don't seem to be able to access the elements within that new window. Any suggestions what I'm missing? Thanks.
That's because the bookmarklet runs within the sandbox (the environment) of the current web page. Since you're not allowed to access (the DOM of) another page which doesn't have the same protocol, domain name and port, you're not able to access the document property of newWindow when protocols, domains and ports don't match. BTW, the same is true for accessing iframes on a page.
As you're talking about an “external form”, I guess you don't stay on the same domain. The other examples retrieve or manipulate data on the current page (at that moment) and won't error out.
Also see Same origin policy.
Update: About the Delicious (et al.) bookmarklet: its code actually reads:
(function () {
f = 'http://delicious.com/save?url=' + encodeURIComponent(window.location.href) + '&title=' + encodeURIComponent(document.title) + '&v=5&';
a = function () {
if (!window.open(f + 'noui=1&jump=doclose', 'deliciousuiv5', 'location=yes,links=no,scrollbars=no,toolbar=no,width=550,height=550'))
location.href = f + 'jump=yes'
};
if (/Firefox/.test(navigator.userAgent)) {
setTimeout(a, 0)
} else {
a()
}
})()
So, yes, the parameters are only transferred using a GET request.
I have been struggling with this for a while now, and decided it was time to ask for help.
I am trying to create a print function on an aspx page, and I am using javascript to do this:
function PrintContentCell() {
var display_setting = "toolbar=yes, location=no, directories=yes, menubar=yes,";
display_setting += "scrollbars=yes, width=750, height=600, left=100, top=25";
var content_innerhtml = document.getElementById("testTable").innerHTML;
var document_print = window.open("Loading.htm", "", display_setting);
document_print.document.open();
document_print.document.write('<html><head><title>Print</title></head>');
document_print.document.write('<body style="font-family:verdana; font-size:12px;" onLoad="self.print();self.close();" >');
document_print.document.write(content_innerhtml);
document_print.document.write('</body></html>');
document_print.print();
document_print.document.close();
return false;
}
I get "Access Denied" when the script tries to write to the new window. The Loading.htm file is just a very slim html document writing out the text "Loading...". I had hoped this would work after reading this thread: IE 6/7 Access Denied trying to access a popup window.document
Anybody can help?
If you want a new, empty popup window to write into, the usual approach is use an empty string for the URL:
window.open('', '_blank', features)
There's no point trying to open HTML from the server when you're immediately going to replace all the content before it's even had a chance to load. (Your empty window name "" may also cause problems.)
However, this is in any case not a good way to implement a “print version” of a page. Instead, use a print stylesheet which hides all but the contents of testTable.
Could you not simply .write() the "Loading" markup after creating an empty (window.open("", ...)) popup?
It would avoid a trip to the server, seem more responsive to the user and solve your problem.
Edit In-fact, as your just shuffling data about on the client side, does the time it takes to render the HTML really warrant a loading banner?
