I want to know how to handle navigation between html pages. When I am using
window.location.href = "Screen1.html";
I am able to load the new page, but when I click the back button, the application gets terminated. How can I handle this?
In native java blackberry, the screen will be on stack, so how it be done in webworks?
i think the better way is to use HTML url
<a href="Screen1.html" >
at the second page when you click on back button it will take you to the previews screen "as the normal browser do"

I've used Vuejs and Framework7 in my PWA. I want to open a remote PDF file in my PWA and also it's important to me that users be able to back to my PWA after opening PDF. I did this using :
window.open(pdf_url, "_blank");
And it works fine for iOS > 12 and after opening pdf file there is an "OK" button for closing pdf.
But for example in iOS 11.3 there is no button and user has to use home button to close PWA.
I tried to solve problem using iframe but I can show only first page of the pdf.
Is there any way to fix this issue?
You can resolve this issue by doing some tricks (for any device without back button):
if you use iframe, you can set height manualy with overflow scroll, and I think this will resolve issue (dependence of style or lib dependency, so that may be not work).
you can add back button to your navbar, or Toolbar to let user click on it to back to previous page. (I prefer this solution).
you can render pdf in popup nested of normal html page, and then you can customize popup component by handling back button, or handling close by dropback overlay.
I use second and third point in real project and its work fine...
This is sample close button code used in popup:
'<p>'+ i18nextHelper.i18next.t('Exit From PDF') +'</p>'
Note: You can also customize height page for pdf page only, and add normal button bellow it, or by add absolute positioning button above PDF, but I think if you use second or third point will be best.
Good luck.
I'm working on pretty simple web side that cointains login screen (almost same as in demo presentation, white page with login and password) and main screen with sidebar and navigation bar. How should it be done? My plan is to build main screen using navigation bar, sidebar (just few buttons in layout basicly) and few layouts with content of the webside. On each button click change layout used to create content to another one, for example for Schudele button I'm gonna load layout that contains some tables, for About button plain text. Is it good idea?
So finnaly is should look like this:
init() function decides if user is logged or not and display Login page or Main page, Main Page is builded from modules like navbar, sidebar and content, content depends on sidebar buttons click. I'm right?
Handling it on your own is legit way to start or learn Vaadin. If you have a first grasp of this works out, the most common way to handle such a scenario is the use of the Navigator See the book of Vaadin.
With the Navigator you define Views and give them a name, register them with the Navigator. Then you can navigate your application with the Navigator, it takes care to give you nice ...#!view... URLs so the Users can have bookmarks and navigate your app also e.g. with the back button in the browser.
The Navigator hooks into an event system, where listeners (ViewChangeListener) can react to "before enter" and "leave". The "before enter" can be used to realize auth needs, since they are allowed to object entering a view.
I am developing an application, where I need to open a full-screen WebView over my existing XAML page.
Now I've added a AppBar over this WebView. The requirement is that, appBar button click should navigate me to different application Page.
e.g. WebView is opened on MainPage.xaml and on clicking the AppBar button added on this webView I have to navigate to SeconsPage.XAML
I am not able to do this now and seeing an exception thrown by COntrol_webview,exe
Can I do such navigation? If Yes, pleas help me to find out what I am I missing?
Thanks in advance!!
go for a native app - it saves you a lot of trouble. Filip Skakun already described the first crazy thing about the webview (with the webviewbrush).
if not, you can use the script notification to communicate back and forth between your webapp and your store app. here's a good link: http://blogs.msdn.com/b/wsdevsol/archive/2012/10/18/nine-things-you-need-to-know-about-webview.aspx
I´m using jquery mobile for an iPad app, and I wanted to have the typical splitview layout so I used the splitview plugin which is working fine until now, but I would still have some minor questions:
Can my first page be a normal page, meaning non-split and then when for example I click on a button go to the second page which would be split?
How do I do to enlarge the left panel if I find it a bit narrow?
Thank you for your help.
I am having the same issue.
I am able to workaround this by providing rel="external" on the link in my navigation menu. This however reloads the entire page, and the ajax effect is gone.
<li>Some Text</li>
I will be spending some time on it this weekend to get it working through ajax, will let you know if I find a solution.
I have a BrowserField in my application displaying a webpage.
Is there a way to detect browser navigation when user clicking on one link in the webpage and move to another webpage?

Not sure if this will trigger it however if you look at the api you can see all your options.
Let me know if you find it.
