It is possible to add multiple reCAPTCHAS in one form? I tried doing so, even giving the multiple reCAPTCHAS different IDs, but when I load the page in the browser, only one of them is shown.
Is this by design? I need the two reCAPTCHAS because one is for Login, and the other one is for the Register form, which will be shown on the same page.
Thanks!

Only one Cpatcha is supported in a page at any time. What you can do is use AJAX and lod captcha after the form is loaded.
This might of some help.
After a quick google search, it appears that it's not currently possible. One suggestion I saw was to pop up a modal recaptcha just as the user submits the form. ondemandcaptcha for Ruby.
I was initially lead by this thread to believe there is no simple answer, but after digging through the Recaptcha ajax library I can tell you this isn't true! TLDR, working jsfiddle: http://jsfiddle.net/Vanit/Qu6kn/
It's possible to overwrite the Recaptcha callbacks to do whatever you want with the challenge. You don't even need a proxy div because with the overwrites the DOM code won't execute. Call Recaptcha.reload() whenever you want to trigger the callbacks again.
function doSomething(challenge){
$(':input[name=recaptcha_challenge_field]').val(challenge);
$('img.recaptcha').attr('src', '//www.google.com/recaptcha/api/image?c='+challenge);
}
//Called on Recaptcha.reload()
Recaptcha.finish_reload = function(challenge,b,c){
doSomething(challenge);
}
//Called on page load
Recaptcha.challenge_callback = function(){
doSomething(RecaptchaState.challenge)
}
Recaptcha.create("YOUR_PUBLIC_KEY");
It is now possible to do this easily with explicit recaptcha creation. See my answer here:
How do I show multiple recaptchas on a single page?
It's not too difficult to load each Recaptcha only when needed using the Recaptcha AJAX API, see my post here:
How do I show multiple recaptchas on a single page?
the captcha has an img element #recaptcha_challenge_image element , so after you set the recaptcha in one div say "regCaptch",get that img src attr
,set your other captcha div html to the old one html and then set the #recaptcha_challenge_image src to the src you get , here is a working example
var reCaptcha_src = $('#recaptcha_challenge_image').attr('src');
$('#texo').html($('#regCaptch').html());
$('#recaptcha_challenge_image').attr('src',reCaptcha_src);

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 an webapp and i need to onclick change css style, but i need to save this change in the webapp instaled into the phone of my user, and only in his phone. The javascript for onclick change css style it's working but i don't have no idea to how to save this css changes.
Can somebody help me with this?
Since now thanks
In general CSS styles can't be directly saved on an HTML client.
What you can do is make an Ajax call back to your server and save the information there. The next time the user asks for the page send HTML with the appropriate style class already on the element you wish to style based on the saved information.
There are several hackish client side possibilities involving JavaScript & cookies or local storage but I would avoid that sort of solution if at all possible since it's very likely to lead to an annoying flicker as the page loads and renders styled one way and then the JavaScript finally runs and corrects the style.
To elaborate on my comment:
el1.addEventListener('click', function() {
el2.style.color = 'red';
localStorage['color'] = el2.style.color;
})
And then on startup:
window.addEventListener('load', function() {
if (localStorage['color']) {
el2.style.color = localStorage['color'];
}
}
Of course, you may want to add error checking and fallbacks as appropriate.
I don't have so much experience using AJAX in a MVC application, in fact is my first facing. Please check the below image and note the rectangles.
The image is just an example that I took from internet.
The biggest rectangle is a partial view in my application and I have to render it when the user press Continue or Continuar button. The application should replace the current view for another without refresh the page.
This is the code which I'm testing, note first that I'm passing the first element of a list, but when the user press the button, render the view with the next element index = 2.
public ActionResult DoTest()
{
if (!Request.IsAjaxRequest())
{ }
List<Worksheet> worksheets = new List<Worksheet>()
{
new Worksheet("Hoja 1", ...),
new Worksheet("Hoja 2", ...)
};
return View(worksheets[0]);
}
Can orient me a little bit to know how to implement this feature? I just know that I need to use Ajax.
Have a look through the tutorials and examples here. There's plenty of other material around on the web with information on this subject.
There are many different ways you can achieve this. One way would be to write a custom paging Helper (HtmlHelper) that accepts new content upon the post event. You can view all about Helpers here : Custom HTML Helpers
Another way could be to use partial page rendering to achieve the partial page update upon post event.
If I was you I would combine a partial view with a jquery function to update the content. You can view some help on that here: Change dive content with Jquery
I have a web page that contains a "div" element. On the page, there is javascript to reference the div: document.getElementById('divId'). This was working fine until another developer redesigned the page to use an ASP master page.
Now, document.getElementById('divId') returns null. It appears that ASP.net prepends some characters to the names of elements within contents forms when you use a master page. How can I know what the id of the div is when the page loads?
Update Allow me to give a specific example to clarify the question: My page had a div with ID divNotice. After changing my page to use a master page, I see when I print the source to the page that renders that the div ID is ctl00_ContentPlaceHolder1_divNotice. My question is, how am I supposed to know what the div ID is going to be when the framework is done with it?
I think that this is what you looking for.
document.getElementById('<%=divNotice.ClientID%>')
to get the ID of your element as appears on the html page use .ClientID
Hope this help.
Dynamically create the javascript using Control.ClientID to determine the calculated ID of div.
document.getElementById('<%= DivControl.ClientID %>')
Or search for the element on the client side using the base ID as a search pattern. See here: A generic way to find ASP.NET ClientIDs with jQuery
I prefer the server side calculation, but if you don't do it often and/or your current design prohibits it, the client side way is a reasonable workaround.
you can check i the element exists by checking if it returns not null
if (document.getElementById('divId') != null) { /* do your stuff*/ }
in other words:
if (document.getElementById('divId')) { /* do your stuff*/ }
now you have edited you orginal question i got it.. i would do something like this:
var arrDivs = document.getElementsByTagName('div'),
strDivName = "divId";
for (i=0;i<=arrDivs.length;i++){
if( arrDivs[i].id.indexOf(strDivName) != -1) {
alert("this is it")
}
}
you can see a demo here:
http://jsfiddle.net/pnHSw/2/
i think you could do it better with a regex.
But this is a pure JS way i don't know ASP.net
edit: i think Aristos solution is much cleaner :P
maybe you can use a descendent selector un css
<div id="wrapperControler">
<controler id="controler"></controler>
</div>
wrapperControler controler{
dosomething;
}
I am writing an intranet application and am considering the use of a pop up window. I am not worried about accessibility since it's an intranet app.
The scenario is such as I need to be able to have the same code be used in a server page as well as in the middle of a process; which is why I decided when using it in the middle of the process, it's best to have it as a pop up window to running out of the real estate on the screen.
Any thoughts on this? I am hesitant to use a pop up window in such a manner as I usually only use it for error messages.
I don't completely understand what you're trying to do, but I think a popup window might be somewhat of an issue if the user's browser automatically blocks popup windows. Plus, if you were trying to run a process in the popup window, the user could close it and no longer have a way to check on the process.
Would it be possible to use Ajax to call back to a web service that gives the page information about the process? You could give the user a way to make the Ajax call to check on the status of the process or just have it continually polling in the background.
Edit:
You said you weren't too familiar with Ajax. For the most part, there are libraries to handle all the of hard details. I'll recommend jQuery because that's what I've been using for a while now.
If you go the Ajax route you'll be able to contain everything on one page and make the updates you need to make when the Ajax call is successful. Depending on how you write the code, it should be pretty reusable if you do it right. It really depends on how specific the your needs on each page.
Take a look at the jQuery documentation though. It may have what you need already built into it. Otherwise, someone else might be able to suggest some reasons why their favorite JavaScript library works better for what you're trying to do.
I think you might want to do something like this:
Inside of the parent page:
<input id="btnShowModal" runat="server" type="button" value='Show Modal' onclick="ShowModal()" />
function ShowModal()
{
var retVal = window.showModalDialog("MyPopup.aspx?param1=value","","center=yes;dialogWidth=200px;dialogHeight=200px;status:0;help:0")
if(retVal != "" && retVal != undefined)
{
//This code will be executed when the modal popup is closed, retVal will contain the value assigned to window.returnValue
}
}
Inside of the modal popup:
<input id="btnSave" runat="server" type="button" value='Save' onclick="Save()" />
function Save()
{
window.returnValue = "Whatever you want returned to the parent here"
window.close()
}
The usual argument against popup windows is that they are unreliable. The user may have disabled script initiated popups, I know I have.
In a controlled environment, such as an inranet, you may be able to be guaranteed that this is not the case, but even so, why risk it, there is an alternative.
Instead of popping up a new window just insert a new, absolutely positioned <div> into the document and insert your content into that using ajax or even an <iframe>. There are lots of examples/libraries on the web.
Thickbox for jQuery for example. There are of course scripts that don't require libraries.
I generally use a div with a z-index and absolute positioning; the .show() can be written and called on demand, it would have a button to .close(), and AJAX can make it seem modal so it must be clicked to close if you so desire. Then again, I hate messageboxes.
I was trying to avoid AJAX, simply because I have never used and don't have the time frame to learn it now. However, I am not totally opposed to it.
In short what I need to do is for the pop up window interact back with the page. Imagine that on the page I am building the links of the chain. Each link has unique properties. When user clicks on "ADD LINK" button, I was thinking have a pop up window with the little form and a Save button. The only issue with this is that a pop up needs to interact with the page; we need to know when something has been saved or not saved.
A div on the same page is one way. A pop up is yet another way. Another catch is that this code (adding new link) needs to be reusable, because I am also going to have a page that just creates new links.
