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.

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 page with an iFrame on it.
On the page in the frame I have a button.
What I want is that if the user clicks on the button, another page is opened in it's own new window or tab. This functionality is to show the user a print friendly page.
How can I do this?
This is how I now try it:
Dim sb2 As New StringBuilder
sb2.Append("window.open('")
sb2.Append(sb.ToString)
sb2.Append("','NewPFWindow','menubar=1,toolbar=1,scrollbars=1,resizable=1,sandbox=""allow-same-origin allow-forms""')")
ClientScript.RegisterClientScriptBlock(Me.GetType, "si2", sb2.ToString, True)
sb holds the page like "mypage.aspx"
Another option is to resize the iFrame so the whole page will fit. Is that possible from code-behind?

Just provide a target that has not been named on your site yet, most people will use _blank for that
I.e.
link text
or if you want to tie that to another click-event somewhere else:
window.open('desiredLocationUrl....', "_blank");
Btw. it does not matter if that link is inside an iframe ;)
found it.
Apparently Chrome uses an undocumented feature.
The frame that is trying to put the new page in it's own window or tab, needs an extra option in the sandbox property called "Allow-popup'.
This is not documented on the w3schools.com website.
So by adding this to the sandbox property, you allow the browser to create new window/tab.
I have an iframe that gets loaded when i click on a tab on a page. When i use Firebug to look at the iframe on IE8, all i see is:
iframe id=tabContextFrame class=contextFrame contentEditable=inherit src=/xyz.dt?forward=show&layouttype=NoHeader&runid=1234 name=tabContextFrame url=/xyz.dt?forward=show&layouttype=NoHeader&runid=1234 scrolling=auto
and that's it.The hierarchy below the iframe can't be seen. I want to click on a link within the iframe. To find the elements within the iframe, I did a selenium.click("on the tab that loads the iframe") and then selenium.getHtmlSource(). From this source, I can at least locate my link of interest. I did a selenium.click("//span[text()='Link']") but it doesn't seem to do anything. Any ideas please?
Here is the code:
selenium.click("//span[text()='tab that loads iframe']");
Thread.sleep(5000);
selenium.selectFrame("tabContextFrame");
selenium.mouseOver("//span[text()='Link']");
selenium.mouseDown("//span[text()='Link']");
selenium.mouseUp("//span[text()='Link']");
Thread.sleep(5000);
selenium.selectFrame("null");
I'm guessing you are using Selenium 1.0. Have you looked at Selenium 2.0 and WebDriver. I found the following and it worked for me:
Q: How do I type into a contentEditable iframe? A: Assuming that the
iframe is named "foo":
driver.switchTo().frame("foo");
WebElement editable = driver.switchTo().activeElement();
editable.sendKeys("Your text here");
Sometimes this doesn't work, and this is because the iframe
doesn't have any content. On Firefox you can execute the following
before "sendKeys":
((JavascriptExecutor) driver).executeScript("document.body.innerHTML = '<br>'");
This is needed because the iframe has no content by default:
there's nothing to send keyboard input to. This method call inserts an
empty tag, which sets everything up nicely.
Remember to switch out of the frame once you're done (as all further
interactions will be with this specific frame):
driver.switchTo().defaultContent();
I found this on http://code.google.com/p/selenium/wiki/FrequentlyAskedQuestions
Use driver.switchTo().defaultContent(); first then do your operation
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.
I've implemented a menu for my asp.net page containing some hyperlinks and loading different contents on their clicks, it's using jquery on behind for it's style mostly and it is working fine. But the problem is, what if a refer to this menu from the outside, i can refer to each of the menu items, i pass parameters on querystring, now i can find which item is clicked but how can i force that hyperlink menu item to be clicked on page load. I'm specifing just their navigation urls, how can i specify that if something is passed in querystring than that specific menu item should be forced clicked on pageload.
Any ideas? Thanks in advance.
The real question lies can you cuase a hyperlink click event?
Now I'm using
Page.ClientScript.RegisterStartupScript(typeof(Page),"test1", "<script>document.getElementById('linkButtonId').click();</script>"); but still nothing desirable happens, seems that this row has no effect at all.
Whether the functionality being executed is client side or server side, it might be a good idea to create a function that will accept the id or something of the menu item being clicked and then handle it appropriately.
Thus all the menu items will call the same function. And since you have the parameters in the query string just pass them through to the function which will handle it accordingly and display the correct content?
You need a bit of separation...
Whatever your click does can be moved into a function, then you can call the function on the click of the menu - but you can also call the function at other times as well.
Before:
<a ... onclick="alert('hello');">Click Me</a>
After:
<a ... onclick="fnSayHello();">Click Me</a>
...
var fnSayHello = function() { alert('hello'); };
fnSayHello();
