JS Validate - valid input & loagin bar while remote

JS Validate - valid input & loagin bar while remote

I'm making a simple javascript form with validation. I've already planned
my sintax and everything but I need help with two things:
I've templating my JS to output the error, but how can I change the
inputbox color to "green" for example if the input is OK by validation?
My templating error until now:
$.validator.setDefaults(
{
showErrors: function(map, list)
{
this.currentElements.parents('label:first,
.controls:first').find('.error').remove();
this.currentElements.parents('.control-group:first').removeClass('error');
$.each(list, function(index, error)
{
var ee = $(error.element);
var eep = ee.parents('label:first').length ?
ee.parents('label:first') : ee.parents('.controls:first');
ee.parents('.control-group:first').addClass('error');
eep.find('.error').remove();
eep.append('<p class="error help-block"><span class="help-block
error">' + error.message + '</span></p>');
});
//refreshScrollers();
}
});
Can you help me inserting the function to change the color if it's OK? I
just can't figure it out.
Other thing is about showing a "loading" image while javascript is remotly
checking if the user / email exists. I have everything ready and work, but
I can't and don't know how to show a loading image while it checks (
before give error result ), neither tells the result is OK ( only in those
fields ). My remote function:
$(function()
{
// validate signup form on keyup and submit
$("#registerform").validate({
rules: {
firstname: "required",
lastname: "required",
username: {
required: true,
minlength: 3,
remote:{
url: "inc/core/check_user.php",
type: "post",
data: {
username: function(){
return $( "#username" ).val();
}
}
}
},
password: {
required: true,
minlength: 5
},
confpassword: {
required: true,
minlength: 5,
equalTo: "#password"
},
scode: {
required: true,
minlength: 4,
maxlength: 6,
digits: true
},
scodeconf: {
required: true,
minlength: 4,
maxlength: 6,
digits: true,
equalTo: "#scode"
},
email: {
required: true,
email: true,
remote:{
url: "inc/core/check_email.php",
type: "post",
data: {
email: function(){
return $( "#email" ).val();
}
}
}
},

minlength: 2
},
agree: "required",

zipcode: "required",

maxlenght: $lang['register_jquery_codigoseguranca_max'],

},

equalTo: $lang['register_jquery_codigoseguranca_equalto']
},
}
});
});
Could someone help me with those two things? Thanks in advance!
