I have a very simple form as follows. I want to make it so that the Submit button is disabled, and only enabled after the user has successfully completed the ReCaptcha.
I'm assuming I'm going to need some Javascript / jQuery to do this.
Google's documentation on ReCaptcha 2.0 seems really sparse and dense (to me, anyway). I'd appreciate some pointers:
<form action="something.php" method="post">
Name: <input type="text" size="40" name="name"><br><br>
<div class="g-recaptcha" data-sitekey="############-#####"></div>
<input type="submit" value="Submit" >
</form>
i did the same thing on my test site. however, i used a button instead of submit, so here:
you must add the property data-callback="enableBtn" data-callback property executes the function specified after accomplishment of recaptcha.
<div class="g-recaptcha" data-sitekey="############-#####" data-callback="enableBtn"></div>
and set the id of the button to whatever id you want to and set it to disabled:
<input type="button" value="Submit" id="button1" disabled="disabled">
then on javascript make a function to enable the button
function enableBtn(){
document.getElementById("button1").disabled = false;
}
hope it helps.
