要求用户在提交表单之前单击Google的新Recaptcha [英] Require User to click google's new recaptcha before form submission

问题描述

我在表单(HTML5)中使用了Google的新Recaptcha: https://www.google.com/recaptcha

I am using google's new recaptcha inside my form (HTML5): https://www.google.com/recaptcha

在提交表单之前，是否可以根据需要检查并标记recaptcha? 我想在客户端而不是服务器端对此进行验证.这样，我不必返回表格并警告用户不要为验证码输入任何内容.

Is there a way to check and mark recaptcha as required before form submission? I want to validate this on client side instead of server side. That way, I don't have to go back to the form and warn user about not entering anything for the captcha.

我可以用来检查用户是否在Recaptcha中输入了任何JavaScript吗?

Any javascript that I can use to check whether user enter anything in recaptcha?

推荐答案

您可以检查ID为g-recaptcha-response的textarea字段.您可以执行以下操作:

You can check the textarea field with id g-recaptcha-response. You can do as following:

$("form").submit(function(event) {

   var recaptcha = $("#g-recaptcha-response").val();
   if (recaptcha === "") {
      event.preventDefault();
      alert("Please check the recaptcha");
   }
});

希望这对您有所帮助.
