php，jquery问题：google chrome？

I am having a problem with Google Chrome.

I have a jQuery Registration form: http://www.topgamedb.com/register.php

When the form is filled out on Firefox, it works perfectly.

When the form is filled out on Chrome, it works perfectly - up until you submit (the page just refreshes).

I have tested my posts, and they work for other things, for example:

if (isset($_POST['login'])){
echo "hello";
}

works fine, although if I use the $_POST['register'] one, the page just refreshes.

What could be causing it not to post on Chrome - for this specific post variable? but able to post on Firefox?

The script basically looks like this:

if (isset($_POST['register'])){
    //do this
}else{
    //show form
}

Any help is greatly appreciated.

Have you try to put a value to your register button? (I guess it is submitted but is empty) Try something like

<button onclick="return registration.submitValidate();" class="btn" name="register" value="here_is_my_value" type="submit" style="opacity: 1;"><span>Register</span></button>

I hope it works this way

You need to give the button the id of register as well (is this still needed) as the name.
