Jquery Validate does not validate data by Submit method __jquery

jquery.validate.js automatically validate data when a form (submit) is submitted

$.validator.setdefaults ({submithandler:function () {alert ("submitted!");

	}
	});

		$ (). Ready (function () {//Validate the comment form when it is submitted $ ("#commentForm"). Validate (); Validate signup form on KeyUp and submit $ ("#signupForm"). Validate ({rules: {firstname: "Required", LASTN AME: "Required", Username: {required:true, minlength:2}, Password: {required:true, M Inlength:5}, Confirm_password: {required:true, Minlength:5, Equalto: "#password"}, EM
				AIL: {required:true, email:true}, topic: {Required: "#newsletter: Checked", Minlength:2  }, agree: "Required"}, messages: {firstname: ' Please enter your FirstName ', LastName: ' Please enter Your LastName ", Username: {required:" Please enter a username ", minlength:" Your username must consist of At least 2 characters "}, Password: {required:" please provide a password ", minlength:" Your Password must is at least 5 characters long "}, Confirm_password: { Required: "Please provide a password", minlength: "Your password is at must 5 least long", characters o: "Please enter the same password as above"}, email: ' Please enter a valid email address ', agree: "Please AC

			). Val ();
			var LastName = $ ("#lastname"). Val ();
			if (FirstName && lastname &&!this.value) {this.value = FirstName + "." + LastName;

		}
		});
		Code to hide topic selection, disable for demo var newsletter = $ ("#newsletter");
		Newsletter topics are optional, hide at a-var inital = newsletter.is (": Checked"); var topics = $ ("#newsletter_topics") [inital?
		"Removeclass": "AddClass"] ("gray"); var topicinputs = topics.find ("input"). attr ("Disabled",!inital); Show as newsletter is checked Newsletter.click (function () {topics[this.checked?
			"Removeclass": "AddClass"] ("gray");
		Topicinputs.attr ("Disabled",!this.checked);
	}); });

Jquery.validate does not use the form submit method to carry on the data verification

function Jqvalidate ()
{return
	$ (' #formLogin '). Validate ({
		rules:{
			truename: ' Required ',
			Password: ' Required ',
			},
		messages:{
			truename: ' Please enter login username ',
			password: ' Password cannot be empty ',
			}

,} function submitbtn ()
{
	 if (jqvalidate ()) {  
		 $ (' #formLogin '). Submit ();

<form id= "Formlogin" class= "Formlo" autocomplete= "Off" accept-charset= "UTF-8" action= "" method= "POST" >
<div id= "RegForm" >
  <div class= "inputl name" >
	<label>
		<span> user name:</span>
		<input id= "username" class= "input Error" type= "text" value= "" Name= "Truename" placeholder= "" Please enter account ">
	</label>
  </div>
	<div class= "Btns" >
