I have an ASP page (I did not write it and cannot change it) that calls an ASPX page written in VB.NET (I can change it)
Here is code from the ASP page:
<A style="CURSOR: pointer" title="View document" onclick="javascript:window.open('https://MYSERVER/MYPAGE.aspx?param=0123456789', 'popup');">View </A>
So, it pops the page with a parameter, but in order to do something, MYPAGE must know what URL the request came from. Now the problem is Request.UrlReferrer is NULL.
how do I find out which URL the request came from?
Thank you
EDIT: Just making sure everyone understands - I CANNOT change the ASP page. It remains the same opening a new window calling the 2nd page with onclick="javascript:window.open('https://MYSERVER/MYPAGE.aspx?param=0123456789'. The ONLY page I can change is the 2nd page, the one that got called.
You cannot rely on UrlReferrer since it is obtained from a header field that the browser should send, but does not in a number of cases.
The safest and best option is to get the ASP page to provide a param in the URL to identify the requestor.
If you cannot do this, another potential option is to leave the current page in place for the ASP page and create a new page for all other requests that route to the old page with an appropriate parameter to identify the source of the traffic (or vice versa).

I got an ASP NET Core RazorPage having a button which asynchronously replaces a part of the given HTML using an AJAX request.
Besides some text content it renders another button which is intended to post back the side when clicked. It is surrounded by a form element.
However, clicking the button I receive an HTTP 400 with the information "This page isn't working" (Chrome). Other browsers like Firefox return an HTTP 400 as well.
The relevant HTML with the button which has been created by the AJAX call is the one below:
<form method="post">
<button class="btnIcon" title="Todos" id="btnTodos" formaction="PersonManagement/Parts/MyPageName?handler=PerformTodos">Execute action</button>
</form>
As the url exists (I doublechecked it using the browser with a simple GET) I wonder whether the issue could be due to some security settings along with the browser or is there anything I am perhaps missing out here?
Thank you for any hint
Two things here first add this attribute to your form asp-antiforgery="true", then send it's value to the server in your AJAX post request.
jQuery magic starts here :)
token: $('[name=__RequestVerificationToken]').val(),
Antiforgery is ON by default since .net core 2.0 (as far as I remember), so if you do AJAX post you need to send the antiforgery token with each request.
Let us know if it helps. Spread knowledge don't hide it just for yourself :P
Finally I came across a very interesting article from Matthew Jones at https://exceptionnotfound.net/using-anti-forgery-tokens-in-asp-net-core-razor-pages/ about Anti-Forgery Tokens in Razor pages. Worth reading, indeed.
However, independently from that article what solved my issue was simply not to add the <form .. element at the client-side, but already at the server-side. As there is no need for me to explicitly adding it at the client-side, but only the button itself, this is a solution for me which works properly.
A brief summary of my scenario now:
There is a Razor Page containing usual cshtml content along with a <form method="post"..
Some anchor elements also are included, one is triggering a JQuery AJAX call to the server
The JQuery call comes back from the server with some additional HTML including the post button which which I add to the existing HTML.
The button is being rendered inside the now already existing
Clicking the button causes the page to post back in the wanted manner and executes the handler as intended.
Thanks again Stoyan for your input and help with that.
a class="linkEffect" href="javascript:void(0)"
Note : I can get reference link by findelements property but somehow when I click on it than on redirect page I loss base as well I am not able get HTTP response like 200 - 404 - 500.
Please let me know if you have any perfect solution for it.
With below code I just get Main link which is not href="javascript:void(0)" also I get only for One Page i.e. which I mention URL. I want to find throughout website. Below is general code which is not working properly as per my requirement
I have an HTML web resource in an opportunity that produces a css tab control containing all children opportunity to the current record.
I do this through Ajax and javascript and everything works fine, a new tab is made for each child and it shows an opportunity record inside; the only issue is that it will only show the current record inside of this tab - effectively creating an endless loop.
If I paste the URL from the IFrame into the browser it shows the proper record using the right form that I specify(one that doesn't contain another web resource).
Does anyone know why it wouldn't show the same form as it navigates to? If I try google.com it works, just not for this URL:
http://server/CRM/main.aspx?etn=opportunity&pagetype=entityrecord&navbar=off&id=%7B"+val.OpportunityId+"%7D&extraqs=formid%3DC1EC704C-D29B-4786-806F-195D0A80CF07%0D%0A#255409204
Try constructing the URL with this format:
http://server/CRM/main.aspx?etc=3&extraqs=formid%3dC1EC704C-D29B-4786-806F-195D0A80CF07%7d&id=%7b<EnterOppIdHere>%7d&pagetype=entityrecord
Use the Entity Type Code (etc parameter) instead of the Name (etn) and note that everything after that should be part of the extraqs parameter.
I've tried to find an answer to this (both in the dev docs and here), but with no luck.
The "+1 button" works fine on normal pages (where there's just the single +1). But I have a page with multiple entities (to use the terms of Drupal: A View displaying multiple nodes) where I'd like to add "share buttons". So far I've added Twitter and Facebook.
Twitter is the simplest as it just takes the string you give it..
Facebook takes an url, but you can specify your own url.
When I try to specify my own url for +1 I get this Error:
Unsafe JavaScript attempt to access frame with URL http://one80.seasites.se/whats-up from frame with URL https://plusone.google.com/_/+1/hover?hl=sv&url=http%3A%2F%2Fone80.seasites.se%2Fwhats-up%2Fl%25C3%25B6rdag&t=1342724634133&source=widget&isSet=false&referer=http%3A%2F%2Fone80.seasites.se%2Fwhats-up&jsh=m%3B%2F_%2Fapps-static%2F_%2Fjs%2Fgapi%2F__features__%2Frt%3Dj%2Fver%3Dr4LFRxx-_oY.sv.%2Fsv%3D1%2Fam%3D!ZCfx2q5v6YmYvWjcTQ%2Fd%3D1%2Frs%3DAItRSTNI50TT3SY8R9klRLc_1sBJ5_Rp3g#id=I3_1342724634541&parent=http%3A%2F%2Fone80.seasites.se&rpctoken=619983104&_methods=mouseEvent%2CtrackingEvent%2ConVisibilityChanged%2C_onopen%2C_ready%2C_onclose%2CcloseOrHideThisBubble%2C_close%2C_open%2C_resizeMe%2C_renderstart.

To explain why I want to use separate URL:
every node is something like an event, every node has it's own url (which contains an image and text/info). So when you click Like (for FB) it gets the title, info & image and includes it in the post (So it says "What's up - Gathering", instead of a generic "What's up" and no/the same image).
I'd like to accomplish the same with G+.
Is there a way to accomplish this for G+?? Have I missed something??
I guess one way to do this is by using an iframe for each of the nodes and pull in a special version of the "node page" with just the g+-button. But that's a pretty nasty hack (and not that fun to set up).
Any ideas are welcome!
The error you're seeing is actually due to an issue in Chrome. The +1 button should automatically recover.
You can explicitly specify target pages by using the href attribute. Your markup will look like this in practice:
<g:plusone href="http://example.com/targeturl"></g:plusone>
Or like this with HTML5 syntax:
<div class="g-plusone" data-href="http://example.com/targeturl"></div>
If these don't work, can you share a link to a page where you're seeing it not work? I can take a look :)
Situation: I needed to add form with POST method to CMS page. I created custom hook and a module displaying the form successfully. Then I need to react to user input errors eg. when user doesn't enter email address I need to detect it, display the whole page again together with the form and with "errors" in user input clearly stated.
Problem: The problem is to display the WHOLE page again with connected information (eg. about errors etc.). In the module PHP file when I add this kind of code,
return $this->display(__FILE__, 'modulename.tpl');
it (naturally) displays ONLY the form, not the whole CMS page with the form.
In case of this code,
Tools::redirectLink('cms.php?id_cms=7');
I can't get to transfer any information by GET neither POST method.
$_POST['test'] = 1;
Tools::redirectLink('cms.php?id_cms=7&test');
I tried to assign to smarty variables too
$smarty->assign('test', '1');
(I need to use it in .tpl file where the form itself is created) but no way to get it work.
{if isset($test)}...,
{if isset($smarty.post.test)}...,
{if isset($_POST['test'])}... {* neither of these conditionals end up as true *}
Even assigning a GET parameter to url has no impact, because there is link rewriting to some kind of friendly url I guess, no matter I included other argument or not. ([SHOPNAME]/cms.php?id_cms=7&test -> [SHOPNAME]/content/7-cmspage-name)
My question is: is there a way to "redirect" or "reload" current page (or possibly any page generally) in prestashop together with my own data included?
I kind of explained the whole case so I'm open to hear a better overall solution than my (maybe I'm thinking about the case in a wrong way at all). This would be other possible answer.
The simplest method would be to use javascript to validate the form - you can use jQuery to highlight the fields that are in error; providing visual feedback on how the submission failed. In effect you don't allow the user to submit the form (and thus leave the page) until you're happy that the action will succeed. I assume that you will then redirect to another page once a successful submission has been received.
There's lots of articles and how-tos available for using javascript, and indeed jQuery for form validation. If you want to keep the site lean and mean, then you can provide an override for the CMS controller and only enqueue the script for the specific page(s) you want to use form validation on.
If the validation is complex, then you might be best using AJAX and just reloading the form section of your page via a call to your module. Hooks aren't great for this kind of thing, so you might want to consider using an alternative mnethod to inject your code onto the cms page. I've written a few articles on this alternative approach which can be found on my prestashop blog
