二、使用JQ完成下拉列表左右选择
<!DOCTYPE html>

/*2.单击全部去右边*/
$("#selectAllToRight").click(function(){
$("#left option").appendTo($("#right"));

/*3.选中双击去右边*/
$("#left option").dblclick(function(){

三、使用JQ完成表单校验
（1）validate入门案例：
<!DOCTYPE html>
<html>

<meta charset="UTF-8">
<title>validate入门案例</title>
<script type="text/javascript" src="../../js/jquery-1.8.3.js" ></script>
<!--validate.js是建立在jquery之上的，所以得先导入jquery的类库-->
<script type="text/javascript" src="../../js/jquery.validate.min.js" ></script>
<!--引入国际化js文件-->
<script type="text/javascript" src="../../js/messages_zh.js" ></script>
<script>
$(function(){
$("#checkForm").validate({
rules:{
username:{
required:true,
minlength:6
},
password:{

digits:"密码必须是整数!",
minlength:"密码不得少于6位!"
}
}
});
});
</script>
