reCAPTCHA - to appear after press submit

阅读更多关于 reCAPTCHA - to appear after press submit

问题 I wanna use reCAPTCHA for my form. The user must fill the form and then press "Submit". After this, under the "Submit"-Button, reCAPTCHA should appear. How I can do this? 回答1: If I were to want something like this, I would probably preload the reCAPTCHA into a jQuery dialog.

If not, can you recommand me an alternative for this reCaptcha that allows per default all the domains ? Thanks a lot in advance 回答1: For multiple domains you can use the Secure
