I am looking for a code compatible with ReCaptcha to reload it using JavaScript. javascript recaptcha share|improve this question asked Jul 30 '10 at 12:21 ahmet alp balkan 10.7k1762118 1 Don't bother. Why change the CAPTCHA if the username is taken? –SLaks Jul 30 '10 at 12:25 13 @SLaks: probably because he first checks captcha and then checks the user - and once captcha is used, it is no longer valid. Doing this the other grecaptcha.reset() not working way around the malicious user can easily flaw the server and get the list of all users using brute force without being bothered with captcha. –Tomasz Nurkiewicz Oct 11 '11 at 9:50 add a comment| 6 Answers 6 active oldest votes up vote 199 down vote accepted I think I can answer my own question now. It is Recaptcha.reload(); in JavaScript if there is an already loaded Recaptcha on the window.

Join them; it only takes a minute: Sign up Can't refresh reCaptcha on JQuery Ajax return up vote 4 down vote favorite I'm having a devil of http://stackoverflow.com/questions/3371314/how-to-reload-recaptcha-using-javascript a time trying to get Ajax to automatically refresh on a JQuery AJAX callback. I have a comment box with the messages being refreshed posted immediately upon validation of reCaptcha and it would be nice if the reCaptcha could refresh automatically in case someone wants to add another comment immediately afterward. Here's my return function: $.post(url, formData, function(data) { if (returnString.match(/^Error:/)) { $("#interactionResults").html(data).show().fadeOut(6000); } else if (postNumber == 0) { $('#newCommentDisplay').html(returnString).show(); $.post("http://www.google.com/recaptcha/api", "Recaptcha:reload()"); http://stackoverflow.com/questions/10002961/cant-refresh-recaptcha-on-jquery-ajax-return } When I use: $.post("http://www.google.com/recaptcha/api", "Recaptcha:reload()"); I get an error: XMLHttpRequest cannot load http://www.google.com/recaptcha/api. Origin http://localhost:8888 is not allowed by Access-Control-Allow-Origin. Fair enough, so I try to change that line with this one: $('#recaptcha_reload_btn').trigger('click'); and still nothing is happening. Does anyone know what's going on? javascript ajax jquery recaptcha share|improve this question edited Apr 5 '12 at 4:30 asked Apr 3 '12 at 23:31 John Bowlinger 3761413 ah, by "nothing is happening" do literally mean nothing, or do you still talk of a Google error? –marue Apr 4 '12 at 8:09 Yeah, I literally mean nothing. Sorry I didn't make that clearer. –John Bowlinger Apr 4 '12 at 13:11 Then you need to show your click-handler. Has to be some problem there. –marue Apr 4 '12 at 14:02 @marue It's in an Iframe which is what I think may be tripping me up. I think I may need to send a JSON object back to Google. Here's the iframe:
–John Bowlinger Apr 5 '12 at 4:18 Hm, it's not so easy to catch events from an iframe, i'm not even sure if it is possible. If you have outside that iframe, you could use the answer in this post stackoverflow.com/
