I want to redirect a new tab and to get focus of the new window when a button is clicked.. I can create a new window, but can't get its focus even thourh, I tried the following code
Window.focus(); How to do this?
My Code:
function new_window(url)
{
//Open a Window in New tab
var popupwin = null;
popupwin = window.open(url);
popupwin.focus();
self.focus();
//window.focus();
}
I think it would be better not to do this. These are browser preferences and don't try to override those. It may fail due to user settings.
Remove
self.focus();
You can use focus() method of a form element. This brings mostly the window to front. window.focus() might implemented different by different browsers.
Do you have html input elements on you popup win?
Try calling focus() on one of the html input elements. This will place the cursor into the element to assist the user start typing there.

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.
I have a number of anchors in a page. I want that when the user clicks on an anchor it would open a blank window. I have used target='_blank' and that works correctly. However, I want that if the user clicks on another link in the original page, I would like that it uses the same popup that was opened for the first window. What I do not want is that the user ends up with like 10 popups as this would be a bit messy for the user.
Is this achievable please?
Any assistance would be greately appreciated.
target is deprecated since HTML 4.01, you can however use JS like this:
test
<script>
var clicky = document.getElementById("clicky");
clicky.onclick = function(){
window.open(clicky.href, "test");
return false;
}
</script>
in the window.open, the first attribute is the URL the link should go to, the second is the name of the window, clicking any link setup like this will open in the same window.
there's better and easier ways to do this to multiple elements with jquery etc. but it all hinges on the window.open.
Instead of using _blank (which is a special value for a new window), use a name - any name would do.
target="mySpecialPopup"
When naming a window this way, every time you call it by name it uses the same instance.
Just name your target.
target='mywindow'
This should open a blank window the first click and repopulate it when other target='mywindow' links are clicked.
The jQuery UI dialog drives me up the walls. To the best of my understanding, here's how it works:
When you do $('#myDialog').dialog({...}), it copies the #myDialog element and moves it inside this bizarre widget thing at the bottom of your body tag. This is crazy! It will duplicate possibly unique DOM elements (with ids) when it does this.
So what I'm trying to do is make it behave in a predictable way when I refresh the HTML of the original element (#myDialog). If I do this dynamically, sometimes the dialog doesn't open any more:
http://jsfiddle.net/t67y7/3/
Or sometimes the dialog opens with the old HTML (because it's cached at the bottom of the page that way). What is up with this?
Since nobody seems to have any idea how to tame this beastly dialog, here's the best thing I've come up with to date. I'll accept any superior alternatives.
var original = $('#dialogId')[0];
var clone = $(original).clone().attr('id', 'dialogIdClone');
var saveHtml = $(original).html();
$(original).html('');
$(clone).dialog({
... // other options
open: function (){
// add any dynamic behavior you need to the dialog here
},
close: function(){
$(clone).remove();
$(original).html(saveHtml);
}
});
The purpose of this whole craziness is to keep the HTML of the original dialog unique on the page. I'm not really sure why this can't be the built-in behavior of the dialog... Actually, I don't understand why jQuery UI needs to clone the HTML to begin with.
I know this has been posted for a while, but a less extensive way to handle this issue would be:
$('#your-dialog').dialog({
... // other options
open: function (){
// add any dynamic behavior you need to the dialog here
},
close: function(){
}
});
$('#your-dialog').remove();
This is due to dialog widget wants to be able to control the display and will wrap the inner content of the original dialog then create a brand new one at the bottom of the body.
The draw back of this solution is that the dialogs have to be the first to be initialized to ensure all your 3rd party library widget will operate properly.
Why don't you just call $("#dialogId").dialog("destroy") on close function, like this:
$("#dialogId").dialog({
close: function() {
$(this).dialog("destroy");
// you may want empty content after close if you use AJAX request to get content for dialog
$(this).html('');
}
}
The destroy function will remove the decorated code, and your dialog element will not be duplicate next time you show the dialog.
I added a sample code to jsfiddle.net example.
You need to empty the dialog before opening it.
$("#dialogId").html('');
$("#dialogId").dialog({
close: function() {
$(this).dialog("destroy");
}
}
I would like to add custom right clicks to a number of spark list controls.
I have tried the following as an item renderer. (as per the flex 4 cook book).
Full Render code here http://pastebin.com/Kx8tJ1cY
When I right click on the Spark List I simply get the Adobe Default Context menu.
This is the same default behaviour I had before I added any code to this.
Could anyone tell me how to add right clicks to List Items in Flex 4.
Please and Thank you.
I found the problem/solution. You cant use context menus if there are Vboxes or Tab Navigators. Which is insane because it means I cant do relative layout properly or decent variable width design.
Quoted from: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/ui/ContextMenu.html
For example, if a DataGrid control is a child of a TabNavigator or VBox container, the DataGrid control cannot have its own context menu.
Christopher Huyler posted something similar (source code available here). From the article:
Start out by grabbing the Javascript code from Google's code repository.
Step 1 – Setup custom context menu code
Create a new Flex project in Flex Builder. Copy rightclick.js and swfobject.js into the html-template folder of your project. From here, I had to make several changes…
I modified the RightClick.init() function to accept an object and container value as input. This allows me to pass in the name of the application as the object instead of having it be called the same thing every time.
I included rightclick.js and swfobject.js in the header of index.template.html.
I added a new div to the body called “flashcontent”.
I added an onload handler to the body tag to initialize RightClick
I replaced AC_FL_RunContent(…) with new SWFObject(…) making sure to maintain all template variables.
After making these changes, I verified that no right-click context menu appears in my application.
Step 2 – Listen for the rightClick event
Next I added a few lines to the main mxml file of my application to listen for the ExternalInterface event that will be dispatched when I right-click my appliction.
private function handleCreationComplete():void
{
ExternalInterface.addCallback("rightClick", handleRightClick);
}
private function handleRightClick():void
{
Alert.show("Right Click Success!");
}
Step 3 – Dispatch an event to the correct object
Getting the event to the main application is easy, but we actually want the appropriate child object to be notified when the right-click event occurs. Since I am not using any double-click events in my application I decided I would treat every right-click event like a double-click event. Users without a two button mouse (aka Mac users) can simply double-click to get the same menu while users with a two button mouse just have to right-click. Here is how I make sure the event is dispatched to the appropriate object.
private function handleRightClick():void
{
var objects:Array = systemManager.getObjectsUnderPoint(
new Point(mouseX,mouseY));
if (objects.length>0)
{
var object:Object = objects[objects.length-1];
var relatedObject:InteractiveObject;
if (object is InteractiveObject)
relatedObject = object as InteractiveObject;
else if (object.parent && object.parent is InteractiveObject)
relatedObject = object.parent;
var event:MouseEvent = new MouseEvent(
MouseEvent.DOUBLE_CLICK,true,false,mouseX,mouseY,
relatedObject);
object.dispatchEvent(event);
}
}
I hope this helps!
I'm trying to duplicate the behaviour of the "Share on Facebook" button from Youtube. Basically, inside a Flex app I'll have a button and when I click it I want a popup that enables me to post something on the wall.
While it is possible to make a call to javascript to open the pop-up I want to be able to set the images and the text of my posting.
Do you know how I could set the images or text as a paramter to the sharer window?
Thank you!
This is fairly straightforward to do. Youtube uses the Facebook API which pops up a new window (Info on Facebook sharer API).
To do this in flex,
Create a button that onClick will call a javascript method, ExternalInterface.call("fbLink", "www.yahoo.com");
In your HTML file (most likely index.template.html) add the JavaScript method, fbLink which does the following:
function fbLink(url) {
window.popup("http://www.facebook.com/sharer.php?u=" + url, {height:440, width:620, scrollbars:true})
}
Now when a user clicks on the button they will be sharing the link "yahoo.com" with facebook account.
as I understood you asking for some help in accessing js popup in html page of facebook share button, so you should use ExternalInterface in this casa and access needed DOM node using getElementById function in your js interface.
In other case I want propose you to read another one way http://www.riaxe.com/blog/flex/publish-into-facebook-wall-from-flex/
It seems that you want to have a button on the flash application and once clicked it opens the facebook page that shares the video/image that pertains to the clicked button. What you want to do is simply create a button that on click opens a new website to facebook using their share api which has the following format:
var facebookShare:String = "http://www.facebook.com/share.php?u=' + encodedVideoLink + '&t='+ encodedVideoText";
Where the u parameter stands for the link that you wish to share, and the t parameter stands for the title of the piece that you want to share, whether it be a picture or video.
You want to add an event listener on MouseEvent.CLICK that has as its callback function a method that handles the opening of the facebook page passing the facebookShare variable as shown above. To open another page on your browser you can use this AS3 Class called URLNavigator: http://www.danishmetal.dk/project/source/com/zorked/URLNavigator.as
To sum it up, something along these lines would do:
var facebookShare:String = "http://www.facebook.com/share.php?u=' + encodedVideoLink + '&t='+ encodedVideoText";
facebookButton.addEventListener(MouseEvent.CLICK, this._goToUrl(facebookShare));
private function _goToUrl(link:String):Function {
var window:String = "_blank",
feats = "",
thisOverlay:Object = this; // to not lose scope when returning a func
return function (e:MouseEvent):void {
trace("Opening link to:"+link);
try { URLNavigator.ChangePage(link, window, feats); }
catch (e:Error) { trace("error launching "+link+" in "+window+" with feature set "+feats); }
}
}
I hope that helps. If you have questions regarding the code please let me know.
