jQuery.ajax() با jQuery plugin validation

[binboy]

سلام
چگونه می توان از jQuery.ajax() (http://api.jquery.com/jQuery.ajax/) در jQuery plugin validation (http://bassistance.de/jquery-plugins/jquery-plugin-validation/)استفاده کرد؟

بطور مثال چگونه می شود کد زیر را به کد بعدی اضافه کرد؟

این کد:

$(document).ready(function(){

$('#submit').click(function() {

$('#waiting').show(500);
$('#demoForm').hide(0);
$('#message').hide(0);

$.ajax({
type : 'POST',
url : 'post.php',
dataType : 'json',
data: {
email : $('#email').val(),
url : $('#url').val(),
name : $('#name').val()
},
success : function(data){
$('#waiting').hide(500);
$('#message').removeClass().addClass((data.error === true) ? 'error' : 'success')
.text(data.msg).show(500);
if (data.error === true)
$('#demoForm').show(500);
},
error : function(XMLHttpRequest, textStatus, errorThrown) {
$('#waiting').hide(500);
$('#message').removeClass().addClass('error')
.text('There was an error.').show(500);
$('#demoForm').show(500);
}
});

return false;
});
});

در این کد اضافه کرد:

<script type="text/javascript">
$(document).ready(function() {
// validate signup form on keyup and submit
var validator = $("#signupform").validate({
rules: {
firstname: "required",
lastname: "required",
username: "required",
password: {
required: true,
minlength: 5
},
password_confirm: {
required: true,
minlength: 5,
equalTo: "#password"
},
email: {
required: true,
email: true,
},
dateformat: "required",
terms: "required"
},
messages: {
firstname: "Enter your firstname",
lastname: "Enter your lastname",
username: {
required: "Enter a username",
minlength: jQuery.format("Enter at least {0} characters"),
remote: jQuery.format("{0} is already in use")
},
password: {
required: "Provide a password",
rangelength: jQuery.format("Enter at least {0} characters")
},
password_confirm: {
required: "Repeat your password",
minlength: jQuery.format("Enter at least {0} characters"),
equalTo: "Enter the same password as above"
},
email: {
required: "Please enter a valid email address",
minlength: "Please enter a valid email address",
remote: jQuery.format("{0} is already in use")
},
dateformat: "Choose your preferred dateformat",
terms: " "
},
// the errorPlacement has to take the table layout into account
errorPlacement: function(error, element) {
if ( element.is(":radio") )
error.appendTo( element.parent().next().next() );
else if ( element.is(":checkbox") )
error.appendTo ( element.next() );
else
error.appendTo( element.parent().next() );
},
// specifying a submitHandler prevents the default submit, good for the demo
submitHandler: function() {
$('#waiting').hide(500);
$('#message').removeClass().addClass((data.error === true) ? 'error' : 'success')
.text(data.msg).show(500);
if (data.error === true)
$('#demoForm').show(500);
},
// set this class to error-labels to indicate valid fields
success: function(label) {
// set &nbsp; as text for IE
label.html("&nbsp;").addClass("checked");
}
});

// propose username by combining first- and lastname
$("#username").focus(function() {
var firstname = $("#firstname").val();
var lastname = $("#lastname").val();
if(firstname && lastname && !this.value) {
this.value = firstname + "." + lastname;
}
});

});
</script>
