Google reCAPTCHA example javascript

In this article, I will demonstrate how to implement Google reCAPTCHA  v2 on Client Side using JavaScript, jQuery in ASP.Net. The new reCAPTCHA is here. A significant number of your users can now attest they are human without having to solve a CAPTCHA. We’re calling it the No CAPTCHA reCAPTCHA experience.

Google reCAPTCHA validation asp.net

The Google reCAPTCHA version 2 ASP.Net allows validating the Captcha response on the client side using its Callback functions. In this example, the Google new reCAPTCHA will be validated using ASP.Net RequiredField Validator. Find the source code below:-

  1. I’ve been trying to make it harder for bots to spam a website and I needed it to be in asp.net and C#.

    I checked 100 different forums and 100 different strategies and ways of doing this and every single one eventually stopped working or had a really bad fail.

    You have actually given me the semi-perfect solution which I can maybe make it perfect by looking at another sample of code. Pretty much does everything i needed except showing an error when the recaptcha expires.

    Thank you so much for the help,
    Mário Ferreirinha
