表单的输入类型=“提交”似乎并没有触发onsubmit处理

Question

我试图通过的onsubmit触发JavaScript函数来验证我的形式。

我知道函数本身的作品，因为我可以在表单的标记后，立即script标签内调用它，我收到我的console.log消息，并创建在表单上出现的错误消息。

的PHP验证自己的作品，但我只能够通过实际放置在一个div JavaScript的.submit提交表单。显然，因为这绕过了任何客户端验证，所以我不能这样离开它，因此我用input type="submit"替换了我的div id="submit"。

我一直在寻找其他的例子，包括我自己编码的，我知道的工作，完全好像出答案的过去式。这可能非常容易，出于某种原因，我不能也不能在过去6个小时内看到它。 O_O

这里是我的窗体的标记：的onsubmit="return validateForm();" -with或没有分号

<form name="emailus" id="emailus" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" onsubmit="return validateForm();"> 
    <a href="mailto:example@email.com"> 
     <h3><i class="icon-envelope-alt icon-large"></i>Send us an email<span>: example@email.com</span></h3> 
    </a> 

    <div class="half"> 
     <fieldset class="name"> 
      <label for="cf_name"><h4>Name <span>*</span></h4></label> 
      <input type="text" name="cf_name" class="textualformfield" alt="Jane Doe" pattern="^[a-zA-Z'\s]+$"> 
     </fieldset> 
     <fieldset class="emailaddress"> 
      <label for="cf_email"><h4>E-mail <span>*</span></h4></label> 
      <input type="text" name="cf_email" class="textualformfield" alt="janedoe@email.com" pattern="{long string of regex}"> 
     </fieldset> 
     <fieldset class="phonenumber"> 
      <label for="cf_phonenumber"><h4>Phone</h4></label> 
      <input type="tel" name="cf_phonenumber" class="textualformfield" alt="555-555-5555"> 
     </fieldset> 
     <fieldset class="eventdate"> 
      <label for="cf_eventdate"><h4>Event Date</h4></label> 
      <input type="text" name="cf_eventdate" class="textualformfield" alt="May 25th, 2012"> 
     </fieldset> 
     <fieldset class="location"> 
      <label for="cf_location"><h4>Location</h4></label> 
      <input type="text" name="cf_location" class="textualformfield" alt="The Church"> 
     </fieldset> 
    </div> 

    <div class="half"> 
     <textarea name="cf_message" class="textualformfield" alt="Your Message"></textarea> 
    </div> 

    <input type="submit" for="emailus" name="submit" id="submit" value="Submit"> 
</form> 

我已经尝试几种不同的迭代，写它作为onSubmit或onsubmit ...我不知道。我根本看不出这有什么问题。任何人？

以下被称为onsubmit，validateForm功能。它位于另一个文件中，但该文件始终包含在表单中，并且我确信此函数不在$(document).ready之内，并且可以在全局范围内使用，因为我已经在表单后直接从脚本标记中调用它。

var validateForm = function() { 
    var valid = true; 

    jQuery('p.validationhelpers').remove(); 

    if (document.emailus.cf_email.value == "" || document.emailus.cf_email.value == "janedoe@email.com") { 
     jQuery('.emailaddress').append("<p class='validationhelpers'>Please enter an email address.</p>"); 
     jQuery('.emailaddress>input').focus(); 
     valid = false; 
    } 

    if (document.emailus.cf_name.value == "" || document.emailus.cf_name.value == "Jane Doe") { 
     jQuery('.name').append("<p class='validationhelpers'>Please enter your name.</p>"); 
     jQuery('.name>input').focus(); 
     valid = false; 
    } 
    console.log("I was triggered"); 

    return valid; 
} 

编辑2：增加PHP验证/邮编：

<?php if (!empty($_POST)) { 
    $field_name = $_POST['cf_name']; 
    $field_email = $_POST['cf_email']; 
    $field_phone = $_POST['cf_phonenumber']; 
    $field_eventdate = $_POST['cf_eventdate']; 
    $field_location = $_POST['cf_location']; 
    $field_message = $_POST['cf_message']; 

    $mail_to = 'example@email.com'; 

    //final attempt at validation or email submission preventation 
    if ($field_name == "Jane Doe" || empty($field_name) || $field_email == "janedoe@email.com" || empty($field_email)) { 
     return false; 
    } 


    if (!($field_eventdate == "May 25th, 2012") && !empty($field_eventdate) && !($field_name == "Jane Doe") && !empty($field_name)) { 
     $subject = 'Request for '.$field_date. ' from '.$field_name . 'via thiswebsite.com'; 
    } else { 
     $subject = $field_name . ' has contacted you via thiswebsite.com'; 
    } 

    if (!($field_name == "Jane Doe") && !empty($field_name)) { 
     $body_message = 'Client\'s Name: '.$field_name."\n\n"; 
    } 
    if (!($field_email == "janedoe@email.com") && !empty($field_email)) { 
     $body_message .= 'E-mail: '.$field_email."\n\n"; 
    } 
    if (!($field_phone == "555-555-5555") && !empty($field_phone)) { 
     $body_message .= 'Phone: '.$field_phone."\n\n"; 
    } 
    if (!($field_eventdate == "May 25th, 2012") && !empty($field_eventdate)) { 
     $body_message .= 'Event Date: '.$field_eventdate."\n\n"; 
    } 
    if (!($field_location == "The Church") && !empty($field_location)) { 
     $body_message .= 'Location: '.$field_location."\n\n"; 
    } 
    if (!($field_message == "Your Message") && !empty($field_message)) { 
     $body_message .= 'Message: '. "\n".$field_message; 
    } 

    $headers = 'From: '.$field_email."\r\n"; 
    $headers .= 'Reply-To: '.$field_email."\r\n"; 

    $mail_status = mail($mail_to, $subject, $body_message, $headers); 

    $body_message = stripslashes($body_message); 

    if ($mail_status) { ?> 
     <script language="javascript" type="text/javascript"> 
      jQuery(document).ready(function() { 
       jQuery('#contactus').before("<hr class='confirmationhelpers'><p class='confirmationhelpers'>Your e-mail has been sent!<br/>Thank you! We'll contact you shortly.</p><hr class='confirmationhelpers'>"); 
      }); 
     </script> 
    <?php 
    } 
    else { ?> 
     <script language="javascript" type="text/javascript"> 
      jQuery(document).ready(function() { 
       alert('It seems there\'s been an error. Please, send an email to example@email.com to request your appointment.'); 
      }); 
     </script> 
    <?php 
    } 
} 

?> 

只是要清楚，当我点击提交按钮，绝对没有任何反应。

Answer 1

你jQuery是阻止表单提交这里：

//this hides the contact form if the overlay is clicked. children is there to prevent the children from also having this effect. 
    $('.overlay_vertical_align').click(function() { 
     $('.grey_overlay').fadeOut('slow'); 
    }).children().click(function(e) { 
     return false; 
    }); 

我的意思是，当我调试您的网站，并按下提交按钮，我到达上面的return false;，在此之后，事件处理结束。 （），

的任何原因的情况是，您使用新的HTML5“模式”它试图正则表达式验证您输入它甚至达到你的验证功能之前的属性。删除模式属性并重试。
