I have posted this problem in the PHP section but someone suggested I take it here because the hangup is likely in the JS. I have tried removing the JS validator with varying results; sometimes the form still requires double-clicking and sometimes it works fine. Please see my original post below:

 

 

Hello all,

 

I am an absolute beginner when it comes to PHP and Javascript but wanted a simple contact form for my website. I used the PHP code from one source and the Javascript validator code from another source and all is working fine except for one very annoying bug: I have to press the Submit button twice in order for the form to send the email. I've found that if the validator is already triggered, however, I only need to press the button once for it to submit. I have scoured the internet for a solution to this problem but am realizing this must be a hangup in the particular code I'm using and I'm just not experienced enough to troubleshoot it.

 

A little help is greatly appreciated. Thank you for your time.

 

Here's the client side code (truncated to only show relevant parts):

<html>
<head>

<script src="js/gen_validatorv4.js" type="text/javascript"></script> 

</head>

 

<body>

<form method="post" action="contact.php" name="contactform">

    <div class="row collapse-at-2 half">

<div class="6u">

<input name="name" placeholder="Name" type="text" />

</div>

<div class="6u">

<input name="email" placeholder="Email" type="text" />

</div>

</div>

<div class="row half">

<div class="12u">

<textarea name="message" placeholder="Message"></textarea>

</div>

</div>

<div class="row half">

<div class="12u">

<ul class="actions">

<li><input type="submit" value="Send Message" /></li>

<li><input type="reset" value="Clear form" /></li>

</ul>

</div>

</div>

</form>

<script type="text/javascript">

var myformValidator = new Validator("contactform");

myformValidator.addValidation("name","req",

        "Please provide your name.");

myformValidator.addValidation("email","req",

        "Please provide your email.");

myformValidator.addValidation("message","req",

        "Please enter your message.");

myformValidator.addValidation("email","email",

        "Please enter a valid email address.");

</script>

</body>

I have tried removing the JS validator with varying results; sometimes the form still requires double-clicking and sometimes it works fine.

 

If you still have to double-click after the JavaScript is removed, the problem is most likely your browser or something else.  Pure HTML should not hang like that.

Thanks for your reply. I just tried using the form sans Javascript on a different computer and the form no longer needed to be double-clicked. I think it's safe to say that the main issue is with the JS, and perhaps testing the form in my browser is not helping. If there are any other suggestions, I'll be testing the form on the other computer just to be sure.
