jqueryのvalidateフォーム検証フレームワーク

本文はjqueryの公式の実例に基づいて相応の修正をして、この実例の目的は後でプロジェクトの中でフォームの検証に出会った時に本文の書いた実例に基づいて相応の修正をすることができて、本文はもし何か不当なところがあれば、批判して指摘してください、ありがとうございます!
1.フォームを含める必要があるテストページを作成します.
適切なリソースファイルをインポートするには、次の手順に従います.

<link rel="stylesheet" type="text/css" media="screen" href="css/screen.css" />
<script type="text/javascript" src="js/jquery-1.5.1.js"></script>
<script type="text/javascript" src="js/jquery.validate.js"></script>

2.新規ルールおよび設定スタイル:

<script type="text/javascript">
$.validator.setDefaults({
	submitHandler: function() { alert("submitted!"); }
});

$().ready(function() {
	//       ，      
	$("#testForm").validate();
	$("#signupForm").validate({
		rules: {
			firstname : "required",
			lastname  : "required",
			username  : {
				required : true,
				minlength: 5,
				maxlength: 10
			},
			email: {
				required: true,
				email: true
			},
			password  : {
				required : true,
				minlength: 5
			},
			confirm_password : {
				required : true,
				minlength: 5,
				equalTo  : "#password"
			},
			topic: {
				required: "#newsletter:checked",
				minlength: 2
			},
			agree : "required"

		},
		
		messages: {
			firstname : {
				required : "     ！",
			},
			lastname : {
				required : "     ！"
			},
			username : {
				required : "       ，    5 10     !",
				minlength: "      5   ",
				maxlength: "       10   "
			},
			password : {
				required  : "       ",
				minlength : "     5     !"
			},
			confirm_password : {
				required : "        !",
				minlength: "        5     !",
				equalTo  : "          ！"
			},
			email : "           ！",
			agree : "    /   "
		}
	});
	
	//      ，         
	var newsletter = $("#newsletter");
	//          
	var inital = newsletter.is(":checked");
	var topics = $("#newsletter_topics")[inital ? "removeClass" : "addClass"]("gray");
	var topicInputs = topics.find("input").attr("disabled", !inital);
	//       ，       
	newsletter.click(function() {
		topics[this.checked ? "removeClass" : "addClass"]("gray");
		topicInputs.attr("disabled", !this.checked);
	});
});
</script>

<style type="text/css">
	#testForm { width: 500px; }
	#testForm label { width: 250px; }
	#testForm label.error, #testForm input.submit { margin-left: 253px; }
	#signupForm { width: 670px; }
	#signupForm label.error {
		margin-left: 10px;
		width: auto;
		display: inline;
	}
	#newsletter_topics label.error {
		display: none;
		margin-left: 103px;
	}
	</style>

3.2つのフォームを作成します.

	<form class="cmxform" id="testForm" method="post" action="">
		<fieldset>
			<legend>Please provide your name, email address (won't be published) and a comment</legend>
			<p>
				<label for="cname">   (*)</label>
				<input id="cname" name="name" class="required" minlength="2" />
			<p>
				<label for="cemail">  (*)</label>
				<input id="cemail" name="email" class="required email" />
			</p>
			<p>
				<label for="ccomment">  (*)</label>
				<textarea id="ccomment" name="comment" class="required"></textarea>
			</p>
			<p>
				<input class="submit" type="submit" value="Submit"/>
			</p>
		</fieldset>
	</form>
	
	<form class="cmxform" id="signupForm" method="get" action="">
		<fieldset>
			<legend>Validating a complete form</legend>

			</p>
		</fieldset>
	</form>
