Saya memiliki formulir kontak sederhana di aspx. Saya ingin memvalidasi reCaptcha (sisi klien) sebelum mengirimkan formulir. Tolong bantu.
Kode sampel:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Test Form</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.2/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.2/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css">

<script>
$("#cmdSubmit").click(function () {
//need to validate the captcha
});
</script>
</head>
<body>
<form id="form1" runat="server">
<label class="clsLabe">First Name<sup>*</sup></label><br />
<input type="text" id="txtFName" name="txtFName" class="clsInput" /><br />
<div class="g-recaptcha" data-sitekey="my_key"></div>
<img id="cmdSubmit" src="SubmitBtn.png" alt="Submit Form" style="cursor:pointer;" />
</form>
</body>
</html>
Saya ingin memvalidasi captcha dengan cmdSubmit
