Is this possible? I have an action triggered off as JS, which i respond to appropriately, but sometimes, the request fails at which point I'd like to change to respond_to format to html so that I can redirect to a thank you page. So far I've tried:
redirect_to(thank_you_path, format: 'html') and return if #next_question.nil?
but this still tries to redirect it as a js response, which of course fails......is there anyway I can convert a JS request to an HTML response?
That wouldn't work because it would try to evaluate the html. You would need to return js to redirect the page

Is there a way to check an URL before loading it? Reason why is because I have a URL that is changed dynamically and after multiple changes, the URL returns null and sometimes error on JSON.
Is this possible?
Thanks
I'm using Apache Wicket and I have following problem:
Inside a onSubmit() method I am sending a POST request to external web address with Apache httpClient. As a response I get html (inside my response object).
How can I get Wicket to render this html in browser?
So basically what I'm trying to do here, is simply what would normally happen if I submitted a html form to this web address. However for security reasons I don't want to give user pages containing forms that contain this data I'm trying to send.
You can get the response via getResponse() in any component. (I assume the onSubmit() is on a form).
How about something like:
getResponse().reset();
getResponse().write(htmlPage);
htmlPage should be a CharSequence containing the html page to be rendered.

yield FormRequest('http://addons.prestashop.com/en/modules/featureproduct/ajax-homefeatured.php',
formdata={'type':'new','ajax':'1'},
callback=self.your_callback_method)
bellow are the urls that you can easily catch using fiddler or firebug
this is for featured tab http://addons.prestashop.com/en/modules/featureproduct/ajax-homefeatured.php?ajax=1&type=random
this is for new tab http://addons.prestashop.com/en/modules/featureproduct/ajax-homefeatured.php?ajax=1&type=new
you can request on these url directly to get results you required, although website is using POST request to get data for these url, but i tried with parameter GET request is also working properly
I need to check some database values with a periodically_call_remote function.
I want to redirect if some values have already a certain state.
How to do this? redirect_to in the function does not seem to work.
Do you need to do a refresh on the entire page? You could use javascript to update your content.
The following javascript may work as well.
window.location = "http://www.address.com/"
redirect_to in the return function does not work because it redirects the ajax request to the new page, it doesn't tell the browser to redirect the entire page. You will need to either render back some javascript in the controller that causes the page to redirect, or better: add a callback to the periodically_call_remote call that checks the return value and runs the javascript that Ben suggested.
Check this thread:
Rails 3 equivalent for periodically_call_remote
The first answer to use javascript setInterval worked perfectly.
I have a use case where I am setting the page focus to a particular element (having an anchor before it). When a user is not signed in, there is a redirect to the login page and after signing in, the user is redirected to the page in question, with the URL encoded.
I see that a URL of the form link#target works as expected (focusing on the element) while the url encoded link link%23target doesn't. Is this expected behavior?
Edit: If this is the expected behavior, is there a work around to focus on the target? As in, a way around url encode?
Edit adding more info:
Assuming that there is a code
page1.html
... html before the anchor ...
<a name="test">Some code</a>
... html after the anchor ...
I am accessing the page as page1.html%23test. This doesn't work the same way as page1.html#test. Is there a jQuery method to implement this? Would location.hash contain test even after it has been url encoded? I have no control on changing the url encoding.
Edit:
As I knew which named anchor I wanted to go to after page is redirected, I did a
window.location.hash = namedAnchor
to solve the issue. This JS line is output only if a customer is successfully signed in. Solved my issue, though not the generic answer I was looking for. I was looking for a way to avoid escaping of # in url encode.
Yes. Encoding the # as %23 effectively says "I just mean a plain old "#" character, not a URL fragment". The same is true of other reserved characters: escaping them stops them from having special meaning in the URL.
In your case you do want to encode the URL when passing it to your login page as a parameter, but your login page should decode the URL before performing the redirect.
You can both parse this string with PHP or other script language, or with JavaScript using the encodeURIComponent. I wrote an article for that, you can check on http://www.stoimen.com/blog/2009/05/25/javascript-encode-cyrillic-symbols-with-encodeuricomponent/
Hope that can help you. However despite the default behavior you must check with either method.
