用户提交他们的电子邮件地址，检查电子邮件是否有效且不在数据库中。
我遇到的问题是，一旦表单提交成功，我就无法隐藏表单并显示感谢 div。目前，它用“谢谢!”替换了电子邮件文本框。我不想要的文本。
必须更改或添加哪些内容才能隐藏表单(在通过错误/验证检查后)并显示感谢 div？
谢谢!!
Index.php
<?php
require "includes/connect.php";
$msg = '';
if($_POST['email']){
// Requested with AJAX:
$ajax = ($_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest');
try{
if(!filter_input(INPUT_POST,'email',FILTER_VALIDATE_EMAIL)){
throw new Exception('Invalid Email!');
}
$mysqli->query("INSERT INTO coming_soon_emails
SET email='".$mysqli->real_escape_string($_POST['email'])."'");
if($mysqli->affected_rows != 1){
throw new Exception('You are already on the notification list.');
}
if($ajax){
die('{"status":1}');
}
$msg = "Thank you!";
}
catch (Exception $e){
if($ajax){
die(json_encode(array('error'=>$e->getMessage())));
}
$msg = $e->getMessage();
}
}
?>

$.post("./index.php",{email:$('#email').val()},function(r){

$('#email').val(r.error);
}
else $('#email').val('Thank you!');
working = false;
},'json');
return false;
});
});
// A custom jQuery method for placeholder text:
$.fn.defaultText = function(value){
var element = this.eq(0);
element.data('defaultText',value);
element.focus(function(){
if(element.val() == value){
element.val('').removeClass('defaultText');
}
}).blur(function(){
if(element.val() == '' || element.val() == value){
element.addClass('defaultText').val(value);
}
});
return element.blur();
}
最佳答案
如果您不想用感谢文本替换输入，为什么要这样做？
else $('#email').val('Thank you!');
相反，
其他{
$("#form").hide();
$("#thankyou").show();
}
