Question

我是Polymer的新手，我使用iron-form组件向数据库提交。我的问题是我如何能够将错误报告回铁形式和HTML？我尝试过使用php echo并通过json数组返回它。但它没有显示在网页上。我该怎么做呢？这是我的代码：

include('config.php');
//Require the db file
include('db.php');
$db = new db($dbhost, $dbuser, $dbpassword, $dbmaster);
include('function.php');
$secure = new secure();

//Get the string.
$email = $secure->clean($_GET["email"]);
if ($secure->verify_email($email) == 'false') {
    echo '    <paper-dialog id="error">
    <h2>Error Registering Your Account</h2>
    <div>
      Invalid Email!
    </div>
</paper-dialog> ';
}

我为电子邮件输入了错误的输入：asdff，因此它会故意抛出错误，但是当我提交它时，当我查看网络标签时，没有任何显示，我看到：

<paper-dialog id="error">
    <h2>Error Registering Your Account</h2>
    <div>
      Invalid Email!
    </div>
</paper-dialog>

我的实际表格代码是：

<form is="iron-form" id="formPost" method="post" action="core/register.php">
      <paper-input char-counter error-message="Invalid input!" label="Username" maxlength="25" required name="username"></paper-input>
      <paper-input char-counter error-message="Invalid input!" label="Display Name" maxlength="35" required name="displayname"></paper-input>
      <paper-input char-counter error-message="Invalid input!" label="Password" maxlength="25" required type="password" name="password"></paper-input>
      <paper-input char-counter error-message="Invalid input!" label="Confrim Password" maxlength="25" required type="password" name="cfmpassword"></paper-input>
      <paper-input char-counter error-message="Invalid input!" label="Email" maxlength="25" required type="" name="email"></paper-input>
      <paper-checkbox required>By checking this box, you agree that you're atleast the age of 13 or above.</paper-checkbox>
      <br />

      <br>
      <div>

        <paper-button raised
          onclick="submitForm()"><iron-icon icon="check" style="margin-right:5px;"></iron-icon>Register</paper-button>
      </div>
</form>
<script type="text/javascript">
    function submitForm() {
        document.getElementById('formPost').submit();
    }
</script>

使用iron-ajax时如何显示错误？对不起，如果我的问题不可理解，我真的不知道怎么说出我的问题。

我发现了如何，我只需要在我的js中添加监听器iron-form-error。
