Javascript function like php POST - php

Question

I have an input form builded with Bootstrap. The check of correct data is handled by javascript, and it's set that on click of button "remind me" it pop ups a notification that says that everything is correct. This last part of pop up notification is handled by php POST method, and I want the same pop up to be shown but with javascript instead of php.
The HTML is:
<form class="form-horizontal" id="registerHere" method='post' action=''>
<fieldset>
<div class="control-group">
<div class="controls">
<input type="text" class="span3" id="user_name" name="user_name" rel="popover" data-content="Enter your first and last name." data-original-title="Full Name" placeholder="First name Last name">
</div>
</div>
<div class="control-group">
<div class="controls">
<input type="text" class="span3" id="user_email" name="user_email" rel="popover" data-content="What’s your email address?" data-original-title="Email" placeholder="me#somewhere.com">
</div>
</div>
<div class="control-group">
<div class="controls controls-row">
<input type="text" class="span1" id="inputPLZ" name="inputPLZ" placeholder="Postal" data-content="Insert your area postal code.">
<input type="text" class="span2" id="inputOrt" name="inputOrt" placeholder="Place" data-content="Where are you from?">
</div>
</div>
<div class="control-group">
<label class="control-label" for="input01"></label>
<div class="controls">
<button type="submit" class="btn btn-success" rel="tooltip" title="first tooltip">Remind me</button>
</div>
</div>
</fieldset>
</form>
and the Javascript is
<script type="text/javascript">
$(document).ready(function(){
$('#registerHere input').hover(
function(){
$(this).popover('show')
},
function(){
$(this).popover('hide')
}
);
$("#registerHere").validate({
rules:{
user_name:"required",
user_email:{
required:true,
email: true
},
},
messages:{
user_name:"Enter your first and last name",
user_email:{
required:"Enter your email address",
email:"Enter valid email address"
},
},
errorClass: "help-inline",
errorElement: "span",
highlight:function(element, errorClass, validClass) {
$(element).parents('.control-group').addClass('error');
},
unhighlight: function(element, errorClass, validClass) {
$(element).parents('.control-group').removeClass('error');
$(element).parents('.control-group').addClass('success');
}
});
});
</script>
this is PHP part that I wanna replace with Javascript:
<?php if($_POST) { ?>
<div class="alert alert-success">
Thanks, we have your info, and expect our contact really soon!
</div>
<?php } ?>

The logic you are talking about is not correct. The ear of your server-side is PHP. It is not possible to know that the form posted and the data are delivered to the server without PHP.
