My flex app has a call in it to:
navigateToURL(new URLRequest(_rURL),'_self');
But it takes about 3-5 or even more seconds before it will leave the current page.
If I omit the '_self' the new window opens immediately and the page loads immediate...but only when I set it to _self I get a few seconds of a delay before it loads...I have no idea why but it is annoying.. I am wondering if anyone might have any idea why this is happening or anything I can do?
Thanks!
Some browsers process the request before redirecting to the new page. For example, if the URL is a file to be downloaded it will not redirect. You can use the name or ID of the window or frame to get the same effect, "top", "window", "parent", "self" (not _self) etc. More info here, http://www.howtocreate.co.uk/tutorials/javascript/browserinspecific

So I would like to be able to have a print button for entries in our database so users can print an entry via a print friendly "form".
My thought was to create a separate page, add labels and have those labels pull the relevant information.
I know I can add the open widget information via this code:
app.datasources.ModelName.selectKey(widget.datasource.item._key);
app.showPage(app.pages.TestPrint);
But I'm running into a few problems:
I can't get the page to open in a new window. Is this possible?
window.open(app.pages.TestPrint);
Just gives me a blank page. Does the browser lose the widget source once the new window opens?
I can't get the print option (either onClick or onDataLoad) to print JUST the image (or widget). I run
window.print();
And it includes headers + scroll bars. Do I need to be running a client side script instead?
Any help would be appreciated. Thank you!
To get exactly what you'd want you'd have to do a lot of work.
Here is my suggested, simpler answer:
Don't open up a new tab. If you use showPage like you mention, and provide a "back" button on the page to go back to where you were, you'll get pretty much everything you need. If you don't want the back to show up when you print, then you can setVisibility(false) on the button before you print, then print, then setVisibility(true).
I'll give a quick summary of how you could do this with a new tab, but it's pretty involved so I can't go into details without trying it myself. The basic idea, is you want to open the page with a full URL, just like a user was navigating to it.
You can use #TestPrint to indicate which page you want to load. You also need the URL of your application, which as far as I can remember is only available in a server-side script using the Apps Script method: ScriptApp.getService().getUrl(). On top of this, you'll probably need to pass in the key so that your page knows what data to load.
So given this, you need to assemble a url by calling a server script, then appending the key property to it. In the end you want a url something like:
https://www.script.google.com/yourappaddress#TestPage?key=keyOfYourModel.
Then on TestPage you need to read the key, and load data for that key. (You can read the key using google.script.url).
Alternatively, I think there are some tricks you can play by opening a blank window and then writing directly to its DOM, but I've never tried that, and since Apps Script runs inside an iframe I'm not sure if it's possible. If I get a chance I'll play with it and update this answer, but for your own reference you could look here: create html page and print to new tab in javascript
I'm imagining something like that, except that your page an write it's html content. Something like:
var winPrint = window.open('', '_blank', 'left=0,top=0,width=800,height=600,toolbar=0,scrollbars=0,status=0');
winPrint.document.write(app.pages.TestPage.getElement().innerHTML);
winPrint.document.close();
winPrint.focus();
winPrint.print();
winPrint.close();
Hope one of those three options helps :)
So here is what I ended up doing. It isn't elegant, but it works.
I added a Print Button to a Page Fragment that pops up when a user edits a database entry.
Database Edit Button code:
app.datasources.ModelName.selectKey(widget.datasource.item._key);
app.showDialog(app.pageFragments.FragmentName);
That Print Button goes to a different (full) Page and closes the Fragment.
Print Button Code:
app.datasources.ModelName.selectKey(widget.datasource.item._key);
app.showPage(app.pages.ModelName_Print);
app.closeDialog();
I made sure to make the new Print Page was small enough so that Chrome fits it properly into a 8.5 x 11" page (728x975).
I then created a Panel that fills the page and populated the page with Labels
#datasource.item.FieldName
I then put the following into the onDataLoad for the Panel
window.print();
So now when the user presses the Print Button in the Fragment they are taken to this new page and after the data loads they automatically get a print dialog.
The only downside is that after printing the user has to use a back button I added to return to the database page.
1.
As far as I know, you cannot combine window.open with app.pages.*, because
window.open would require url parameter at least, while app.pages.* is essentially an internal routing mechanism provided by App Maker, and it returns page object back, suitable for for switching between pages, or opening dialogs.
2.
You would probably need to style your page first, so like it includes things you would like to have printed out. To do so please use #media print
ex: We have a button on the page and would like to hide it from print page
#media print {
.app-NewPage-Button1 {
display : none;
}
}
Hope it helps.
1. Here is how it is done, in a pop up window, without messing up the current page (client script):
function print(widget, title){
var content=widget.getElement().innerHTML;
var win = window.open('', 'printWindow', 'height=600,width=800');
win.document.write('<head><title>'+title+'/title></head>');
win.document.write('<body>'+content+'</body>');
win.document.close();
win.focus();
win.print();
win.close();
}
and the onclick handler for the button is:
print(widget.root.descendants.PageFragment1, 'test');
In this example, PageFragment1 is a page fragment on the current page, hidden by adding a style with namehidden with definition .hidden{display:none;} (this is different than visible which in App Maker seems to remove the item from the DOM). Works perfectly...
2. You cannot open pages from the app in another tab. In principle something like this would do it:
var w=window.parent.parent;
w.open(w.location.protocol+'//'+w.location.host+w.location.pathname+'#PrintPage', '_blank');
But since the app is running in frame nested two deep from the launching page, and with a different origin, you will not be able to access the url that you need (the above code results in a cross origin frame access error). So you would have to hard code the URL, which changes at deployment, so it gets ugly very fast. Not that you want to anyway, the load time of an app should discourage you from wanting to do that anyway.
While executing a selenium script, we are getting a overlay (like popup) which is asking to confirm yes or no.
In this case the main problem being the Overlay popup does not come at a constant place,instead it comes at differen places.
example :- consider we have 4 pages to navigate some time it comes in first page and some times it comes in second page, and sometimes
it comes in the same page while we are accessing different elements.sometimes we are not getting overlay.
please let me know how to solve this issue, Thanks in advance
You can handle that through driver options, at least in Internet Explorer. This is how I do in Selenium.NET binding
var options = new InternetExplorerOptions { EnableNativeEvents = false };
options.UnexpectedAlertBehavior = InternetExplorerUnexpectedAlertBehavior.Dismiss;
It will force close any unexpected pop up.
Not sure that this is correct solution, but this must solution of your task.
You can create simple function(method) that checks for existence of this popup with some timeout. And put in in all possible places.
Or you can check it by some timer in another thread(with pause of main thread)
Is there a way to close a pop up window after the page writes binary data (PDF) to the browswer?
Here are the details:
Whenever my web appilcation needs to print, it will pass some parameters over to a pop up window, which will display the print options. When the user clicks on the Print button, it will set the src of a iframe that will call the page that does the printing.
I have PDFConverter to convert URL / HTML to a pdf file. At the end of the converting, it will write the binary to the browser. Here are some code:
response.AddHeader("Content-Type", "binary/octet-stream");
response.AddHeader("Content-Disposition",
"inline; filename=" + fileName + ".pdf; size=" + pdfBytes.Length.ToString());
response.Flush();
response.BinaryWrite(pdfBytes);
response.Flush();
After this is done, i will need to close the pop up window. However it seems like you can't do anything after the response is flushed. Any ideas?
Thanks in advance!

Instead of creating the iframe in the popup window, you could create it in the parent window. This way once the user clicks the print button, you could safely close the popup without interupting the printing process. But instead of going through all the pain of creating new popups windows which might be blocked by some browsers, I would simply create some placeholder in the main page so that the user could choose printing options and then print the document.
Just in case anyone else is having the same problem. This is the solution that seems to work for me.
I use the jQuery Simple Modal to show my option list page. On this page, I have a window timer running every 1 second to check against the server if the print job is done. I use ajax for that. Once the job is done, I update the session variable, and the ajax call to the server will pick up the session value and close the pop up window.
Is it possible to get up to date contents from an iframe? Lemme explain the problem I am encountering:
function modify_iframe(url){
my_iframe.src = url;
iframe_content = my_iframe.contentDocument;
//....code to modify the content goes here,,,,
}
The first time I call modify_iframe(url_a) it sets the source as I would expect but the iframe_content is a blank document.
The second time I run modify_iframe(url_b) it sets the source as I would expect but the iframe_content is actually that of url_a.
So it seems that contentDocument is not returning the contents of the new source, but rather the source before it was changed. Anyone know why that is and if there is a way around it?
Additional background info: We have been adding an event listener to fire off on the iframe load event which occurs when the src is changed. This was giving us the contents when calling contentDocument; however, users were being prompted that our site had unauthenticated content even though we use https for everything including the src. After removing the event listener we no longer receive the unauthenticated content warning, but the contentDocument of our iframe is always one step behind as described above.
Um, first try using a setTimeout to wait for the page content to load. But that's not a nice solution. What browser are you testing on? If it were me I would try to get to the bottom of the "unauthenticated content" error prompt.
I'm showing a modal dialog via "window.showModalDialog(..." which happens in a vbscript function (the page shown is aspx). I'd like to do some resizing of the window based on the number of rows in a datatable that's coming back. So naturally I go to register a startup script that resizes the window based on the number of rows. Well, that didn't work, so I tried to register a script that just showed a msgbox.
The code looks like (in the OnLoad event handler):
if (!this.ClientScript.IsStartupScriptRegistered(typeof(MyPageClassName), "hello"))
{
this.ClientScript.RegisterStartupScript(typeof(MyPageClassName), "hello",
#"<script language=vbscript>
sub fnWindowOnLoad()
MsgBox ""hello""
end sub
<script>", false);
}
if (!this.ClientScript.IsStartupScriptRegistered(typeof(MyPageClassName), "hello"))
{
throw new Exception("Failed to load script");
}
To me it looks like this should work and show a message box that says "hello" when the page loads (I've got the window's onload event set to fnWindowOnLoad). But what happens is nothing, no exception, no alert. I've tried every Type I could think of in the typeof call. Nothing seems to work. The only thing I can think of is that since the dialog is a modal ClientScript.RegisterStartupScript won't run properly. But that doesn't make any sense to me.
I put the MsgBox "hello" call into my script block directly and the alert showed, so it's possible. But I need to modify some arguments in the code behind so I have to use RegisterStartupScript as far as I can tell.
Have you tried opening your window via window.open() rather than window.showModalDialog()? I've seen some postings on the web about incompatibilities between showModalDialog() and RegisterStartupScript.
showModalDialog() is an IE only method, so it's not recommended anyway. I know it's convenient because it returns a value, but there are various ways to simulate this functionality.
Edit: The other problem with showModalDialog() is that IE often caches the results. This means that if one time you calling the dialog, you do not resize it, then another time you do, then 2nd time might get your the first cached dialog. A way to get around this is to add a unique querystring at the end. Like MyDialog.aspx?q=320934 (randomly generated or generated based on server tics).
The solution for this was to have a script that read a value out of a hidden field and then resized the dialog. The value was set on the Page_Load. Using RegisterStartupScript never seemed to work, neither did RegisterClientScript, so I'm pretty sure modal dialog and RegisterXxx don't get along. Need to use window.dialogHeight & window.dialogWidth in the vbscript.
