Editing a BrowserField's History - blackberry

I have a BrowserField in my app, which works great. It intercept NavigationRequests to links on my website which go to external sites, and brings up a new windows to display those in the regular Browser, which also works great.
The problem I have is that if a user clicks a link to say "www.google.com", my app opens that up in a new browser, but also logs it into the BrowserHistory. So if they click back, away from google, they arrive back at my app, but then if they hit back again, the BrowserHistory would land them on the same page they were on (Because going back from Google doesn't move back in the history) I've tried to find a way to edit the BrowserField's BrowserHistory, but this doesn't seem possible. Short of creating my own class for logging the browsing history, is there anything I can do?
If I didn't do a good job explaining the problem, don't hesitate for clarification.
Thanks

One possible solution to this problem would be to keep track of the last inner URL visited before the current NavigationRequest URL. You could then check to see whether the link clicked is an outside link, as you already do, and if it is call this method:
updateHistory(String url, boolean isRedirect)
with the last URL before the outside link. Using your example this should overwrite "www.google.com" with the last inner URL before the outside link was clicked.
Here is some half pseudocode/half Java to illustrate my solution:
BrowserFieldHistory history = browserField.getHistory():
String lastInnerURL = "";
if navigationRequest is an outside link {
history.updateHistory(lastInnerURL, true);
// Handle loading of outer website
} else {
lastInnerURL = navigationRequest;
// Visit inner navigation request as normal
}
http://www.blackberry.com/developers/docs/5.0.0api/net/rim/device/api/browser/field2/BrowserFieldHistory.html#updateHistory(java.lang.String, boolean)

I had a similar but a little bit different issue. Special links in html content like device:smth are used to open barcode scanner, logout etc and I wanted them not to be saved in BrowserFieldHistory. I found in WebWork source code interesting workaround for that. All that you need is throw exception at the end like below:
public void handleNavigationRequest( BrowserFieldRequest request ) throws Exception {
if scheme equals to device {
// perform logout, open barcode scanner, etc
throw new Exception(); // this exception prevent saving history
} else {
// standard behavior
}
}

Javascript void(0)

I came across this piece of code in a website I was asked to help with.
`
<script>
function removeLinks(links) {
if (!arguments[0]) return;
var a = arguments[0];
$(".WaGadgetMenuHorizontal a:not(.wa-authenticateLoginLink), .WaGadgetMenuVertical a:not(.wa-authenticateLoginLink),.WaGadgetMobilePanel a:not(.wa-authenticateLoginLink)").each(function() {
var curhref=$(this).attr('href').split("/")[3];
if (
(typeof(a)=='string' && a==curhref)||
(typeof(a)=='object' && ($.inArray(curhref, a)>-1))
) {
$(this).attr("href", "javascript:void(0)").css("cursor","context-menu");
}
});
}
removeLinks("Philanthropy");
</script>`
This makes the Philanthropy link unclickable but there are 2 issues to be resolved.
Clicking the Philanthropy link shows the words Javascript:void(0) in the bottom left of the screen
Clicking the Philanthropy link takes you to whatever page you were on previously which is confusing to users, especially on the mobile version of the website where you simply jump from the click on the link to whatever previous page you were on. AT least on the PC you are still on the link with the previous page in the background so to speak.
Is there a way to remove the message that shows at the bottom left of the screen and to click on the link and stay on the link unless you click away to another link?
I tried to modify the code with different things that I found online but nothing seems to work

NetSuite/Suitescript/Workflow: How do I open a URL from a field after clicking button?

I have a workflow that adds a button "Open Link" and a field on the record called "URL" that contains a hyperlink to an attachment in NetSuite. I want to add a workflow action script that opens this url in a different page. I have added the script and the workflow action to the workflow. My script:
function openURL() {
var url = nlapiGetFieldValue('custbody_url');
window.open(url);
}
I get this script error after clicking the button: "TypeError: Cannot find function open in object [object Object].
How can I change my script so it opens the URL in the field?
(This function works when I try it in the console)
Thanks!
Do you want it to work when the record is being viewed or edited? They have slightly different scripts. I'm going to assume you want the button to work when the record is being viewed, but I'll write it so it works even when the document is being edited as well.
The hard part about the way Netsuite has set it up is that it requires two scripts, a user event script, and a client script. The way #michoel suggests may work too... I've never inserted the script by text before personally though.
I'll try that sometime today perhaps.
Here's a user event you could use (haven't tested it myself though, so you should run it through a test before deploying it to everyone).
function userEvent_beforeLoad(type, form, request)
{
/*
Add the specified client script to the document that is being shown
It looks it up by id, so you'll want to make sure the id is correct
*/
form.setScript("customscript_my_client_script");
/*
Add a button to the page which calls the openURL() method from a client script
*/
form.addButton("custpage_open_url", "Open URL", "openURL()");
}
Use this as the Suitescript file for a User Event script. Set the Before Load function in the Script Page to userEvent_beforeLoad. Make sure to deploy it to the record you want it to run on.
Here's the client script to go with it.
function openURL()
{
/*
nlapiGetFieldValue() gets the url client side in a changeable field, which nlapiLookupField (which looks it up server side) can't do
if your url is hidden/unchanging or you only care about view mode, you can just get rid of the below and use nlapiLookupField() instead
*/
var url = nlapiGetFieldValue('custbody_url');
/*
nlapiGetFieldValue() doesn't work in view mode (it returns null), so we need to use nlapiLookupField() instead
if you only care about edit mode, you don't need to use nlapiLookupField so you can ignore this
*/
if(url == null)
{
var myType = nlapiGetRecordType();
var myId = nlapiGetRecordId();
url = nlapiLookupField(myType, myId,'custbody_url');
}
//opening up the url
window.open(url);
}
Add it as a Client Script, but don't make any deployments (the User Event Script will attach it to the form for you). Make sure this script has the id customscript_my_client_script (or whatever script id you used in the user event script in form.setScript()) or else this won't work.
Another thing to keep in mind is that each record can only have one script appended to it using form.setScript() (I think?) so you may want to title the user event script and client script something related to the form you are deploying it on. Using form.setScript is equivalent to setting the script value when you are in the Customize Form menu.
If you can get #michoel's answer working, that may end up being better because you're keeping the logic all in one script which (from my point of view) makes it easier to manage your Suitescripts.
The problem you are running into is that Workflow Action Scripts execute on the server side, so you are not able to perform client side actions like opening up a new tab. I would suggest using a User Event Script which can "inject" client code into the button onclick function.
function beforeLoad(type, form) {
var script = "window.open(nlapiGetFieldValue('custbody_url'))";
form.addButton('custpage_custom_button', 'Open URL', script);
}

Caching visited page in Jquery Mobile

I work on Jquery Mobile/Phonegap app for android.
I´d like my app to "remember" that(if) the user has visited one of my pages. For example if he once visits "page1.html", this action should be cached in the phone memory, so that when the user opens the app again there should be possibility to navigate to this "page2.html" directly from "index.thml".
Please, if you have a code suggestion, tell me also how/where do I use it, because sometimes for starters like me it is realy hard to understand what to do with a little piece code.
Thank you very much!
You can use HTML5 local storage for this purpose.
Each time when a page is shown you can save/update the current page URL to a local storage variable, say 'lastVisit', as below:
$(document).on('pageshow', function (event, data) {
var currentPage = $('.ui-page-active').data('url');
localStorage.setItem("lastVisit", currentPage);
});
If you are not getting $('.ui-page-active').data('url'), then you can use $.mobile.activePage.attr('id') which will give you the current page id.
So next time, when the user opens the app again, you can check whether this local storage variable is set and can action accordingly.
The code will look like as below:
$(document).on('mobileinit', function(){
var lastVisit = '';
if(localStorage.getItem("lastVisit") != null){
lastVisit = localStorage.getItem("lastVisit");
}
if(lastVisit){
document.location.href = lastVisit;
}
});
You can use these codes in the header section scripts.

ie9: annoying pops-up while debugging: "Error: '__flash__removeCallback' is undefined"

I am working on a asp.net mvc site that uses facebook social widgets. Whenever I launch the debugger (ie9 is the browser) I get many error popups with: Error: '__flash__removeCallback' is undefined.
To verify that my code was not responsible I just created a brand new asp.net mvc site and hit F5.
If you navigate to this url: http://developers.facebook.com/docs/guides/web/#plugins you will see the pop-ups appearing.
When using other browsers the pop-up does not appear.
I had been using the latest ie9 beta before updating to ie9 RTM yesterday and had not run into this issue.
As you can imagine it is extremely annoying...
How can I stop those popups?
Can someone else reproduce this?
Thank you!
I can't seem to solve this either, but I can at least hide it for my users:
$('#video iframe').attr('src', '').hide();
try {
$('#video').remove();
} catch(ex) {}
The first line prevents the issue from screwing up the page; the second eats the error when jquery removes it from the DOM explicitly. In my case I was replacing the HTML of a container several parents above this tag and exposing this exception to the user until this fix.
I'm answering this as this drove me up the wall today.
It's caused by flash, usually when you haven't put a unique id on your embed object so it selects the wrong element.
The quickest (and best) way to solve this is to just:
add a UNIQUE id to your embed/object
Now this doesn't always seem to solve it, I had one site where it just would not go away no matter what elements I set the id on (I suspect it was the video player I was asked to use by the client).
This javascript code (using jQuery's on document load, replace with your favourite alternative) will get rid of it. Now this obviously won't remove the callback on certain elements. They must want to remove it for a reason, perhaps it will lead to a gradual memory leak on your site in javascript, but it's probably trivial.
this is a secondary (and non-optimal) solution
$(function () {
setTimeout(function () {
if (typeof __flash__removeCallback != "undefined") {
__flash__removeCallback = __flash__removeCallback__replace;
} else {
setTimeout(arguments.callee, 50);
}
}, 50);
});
function __flash__removeCallback__replace(instance, name) {
if(instance != null)
instance[name] = null;
}
I got the solution.
try {
ytplayer.getIframe().src='';
} catch(ex) {
}
It's been over a months since I last needed to debug the project.
Facebook has now fixed this issue. The annoying pop-up no longer shows up.
I have not changed anything.

WatiN: Print Dialog

I have a screen that pops up on load with a print dialog using javascript.
I've just started using WatiN to test my application. This screen is the last step of the test.
What happens is sometimes WatiN closes IE before the dialog appears, sometimes it doesn't and the window hangs around. I have ie.Close() in the test TearDown but it still gets left open if the print dialog is showing.
What I'm trying to avoid is having the orphaned IE window. I want it to close all the time.
I looked up DialogHandlers and wrote this:
var printDialogHandler = new PrintDialogHandler(PrintDialogHandler.ButtonsEnum.Cancel);
ie.DialogWatcher.Add(printDialogHandler);
And placed it before the button click that links to the page, but nothing changed.
The examples I saw had code that would do something like:
someDialogHandler.WaitUntilExists() // I might have this function name wrong...
But PrintDialogHandler has no much member.
I initially wasn't trying to test that this dialog comes up (just that the page loads and checking some values on the page) but I guess it would be more complete to wait and test for the existence of the print dialog.
Not exactly sure about your situation, but we had a problem with a popup window that also displayed a print dialog box when loaded. Our main problem was that we forgot to create a new IE instance and attach it to the popup. Here is the working code:
btnCoverSheetPrint.Click(); //Clicking this button will open a new window and a print dialog
IE iePopup = IE.AttachToIE(Find.ByUrl(new Regex(".+_CoverPage.aspx"))); //Match url ending in "_CoverPage.aspx"
WatiN.Core.DialogHandlers.PrintDialogHandler pdhPopup = new WatiN.Core.DialogHandlers.PrintDialogHandler(WatiN.Core.DialogHandlers.PrintDialogHandler.ButtonsEnum.Cancel);
using (new WatiN.Core.DialogHandlers.UseDialogOnce(iePopup.DialogWatcher, pdhPopup)) //This will use the DialogHandler once and then remove it from the DialogWatcher
{
//At this point the popup window will be open, and the print dialog will be canceled
//Use the iePopup object to manage the new window in here.
}
iePopup.Close(); // Close the popup once we are done.
This worked for me:
private void Print_N_Email(Browser ie)
{
//Print and handle dialog.
ie.Div(Find.ById("ContentMenuLeft")).Link(Find.ByText(new Regex("Print.*"))).Click();//orig
Browser ie2 = Browser.AttachTo(typeof(IE), Find.ByUrl(new Regex(".*Print.*")));
System.Threading.Thread.Sleep(1000);
PrintDialogHandler pdh = new PrintDialogHandler(PrintDialogHandler.ButtonsEnum.Cancel);
new UseDialogOnce(ie2.DialogWatcher, pdh);
ie2.Close();
}
You still might want to check your browser AutoClose property ie.AutoClose
