我有兴趣在用户打勾并验证google recaptcha后立即隐藏resultcaptcha消息.只有第一部分(v.length == 0)有效.否则如果不起作用.你可以在这里查看表格:https://csandreas1.herokuapp.com
if(grecaptcha.getResponse() == 0) // this works
{
$('#resultcaptcha').show();
$('#resultcaptcha').html('<i class="fa fa-exclamation-circle w3-text-red fa-3x" aria-hidden="true"></i> <span class="w3-text-white w3-bold" style="font-size:16px"> Please verify that you are a human</span>');
}
else if(grecaptcha.getResponse() == 1)//this doesn't work
{
$('#resultcaptcha').hide();
$('#resultcaptcha').html('');
}
else{//submit the form}
