由 南笙酒味 提交于 2019-12-06 08:19:48
I want to get the current captcha that is displayed on a website. An example of this would be http://top100arena.com/in.asp?id=58978 How would I get the image link of the captcha that is displayed other than right clicking - > open image in new page? You are looking for the div identified by "rechapta_image" : Then extract the src attribute of the img element inside this div. To do this, you can choose for an easy String-operation-based way or use a HTML parsing library like JSoup . Here is an example of such an extract URL: http://www.google.com/recaptcha/api/image?c=03AHJ

How do I correctly Re-render a Recaptcha in ASP.NET MVC 2 after an AJAX POST

由 空扰寡人 提交于 2019-12-06 06:22:26
问题 Ok... I've downloaded and implemented this Recaptcha implementation for MVC which uses the ModelState to confirm the validity of the captcha control. It works brilliantly... except when I start to use it in an AJAX Form. In a nutshell, when a div is re-rendered with AJAX, the ReCaptcha that it should contain does not appear, even though the relevant <scripts> are in the source after the partial render. Code Below. using (Ajax.BeginForm("CreateComment", "Blog", new AjaxOptions() { HttpMethod =

reCAPTCHA: why can't I check the same result twice?

由 北慕城南 提交于 2019-12-05 20:42:07
问题 I mean if I check first clients input and it is OK the second check of the same input is always false... Why is that?

I can't see any spaces within the language files - in fact I've redownloaded the entire EN package just to make sure..
