body {margin:0;font-family:'Microsoft YaHei','Lantinghei SC','Open Sans',Arial,'Hiragino Sans GB','STHeiti','WenQuanYi Micro Hei','SimSun',sans-serif;}
/* block */
.st-block,
.st-btn.st-block,

/* disabled */
.disabled, [disabled],
.st-btn.disabled, .st-btn[disabled],
.st-control.disabled, .st-control[disabled] {opacity:0.6;filter:alpha(opacity=60);cursor:not-allowed;}

.st-btn {line-height:20px;padding:5px 20px;box-sizing:border-box;display:inline-block;text-align:center;border-radius:3px;border:1px solid transparent;color:#333;cursor:pointer;}

	<h1 style="text-align:center;padding-bottom:30px;font-size:24px;">简单易用的jQuery表单验证插件validator.js</h1>

	<input type="text" placeholder="邮箱地址" class="st-control st-block" name="umail" value="admin@sucaihuo.com" />

页面的底部，需引入jQuery库和验证插件，并设置验证的容器和对应规则，代码如下：

<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/validator.js" charset="utf-8"></script>
<script>
var eles = {
	form : $('#upForm'),
	umail : $('[name="umail"]'),
	upwd : $('[name="upwd"]'),
	urepwd : $('[name="urepwd"]'),
	usex : $('[name="usex"]'),
	uhob : $('[name="uhob"]'),
	ucolor : $('[name="ucolor"]'),
	submit : $('#submit'),
	err1 : $('#err1'),
	err2 : $('#err2'),
	err3 : $('#err3'),
	err4 : $('#err4'),
	err5 : $('#err5'),
	err6 : $('#err6'),
	errTxt1 : '邮箱格式错误！',
	errTxt2 : '密码格式错误！',
	errTxt3 : '两此输入的密码不一致！',
	errTxt4 : '必须选择性别！',
	errTxt5 : '请选择爱好2-4项！',
	errTxt6 : '请选择喜欢的颜色！',
	norm_mail : /^([a-zA-Z0-9]+[-_.]?)*[a-zA-Z0-9]+@([a-zA-Z0-9]+[-_.]?)*[a-zA-Z0-9]+\.[a-zA-Z]{2,6}$/,
	norm_pwd : /^(?![a-zA-Z]+$)(?![A-Z0-9]+$)(?![A-Z\W_]+$)(?![a-z0-9]+$)(?![a-z\W_]+$)(?![0-9\W_]+$)[a-zA-Z0-9\W_]{8,18}$/,
	norm_sex : 1,
	norm_hob : '[2,4]',
	norm_color : /\S+/
};

//邮箱校验
eles.umail.on('change',function(){
	eles.umail.validator( eles.norm_mail, eles.err1, eles.errTxt1 );
});
//密码校验
eles.upwd.on('change',function(){
	eles.upwd.validator( eles.norm_pwd, eles.err2, eles.errTxt2 );
});
//确认密码校验
eles.urepwd.on('change',function(){
	eles.urepwd.validator( eles.upwd.val(), eles.err3, eles.errTxt3 );
});
//性别校验
eles.usex.on('change',function(){
	eles.usex.validator( eles.norm_sex, eles.err4, eles.errTxt4 );
});
//爱好校验
eles.uhob.on('change',function(){
	eles.uhob.validator( eles.norm_hob, eles.err5, eles.errTxt5 );
});
//颜色校验
eles.ucolor.on('change',function(){
	eles.ucolor.validator( eles.norm_color, eles.err6, eles.errTxt6 );
});

//提交
eles.submit.on('click',function(){
	if( 
		eles.umail.validator( eles.norm_mail, eles.err1, eles.errTxt1 ) &&
		eles.upwd.validator( eles.norm_pwd, eles.err2, eles.errTxt2 ) &&
		eles.urepwd.validator( eles.upwd.val(), eles.err3, eles.errTxt3 ) &&
		eles.usex.validator( eles.norm_sex, eles.err4, eles.errTxt4 ) &&
		eles.uhob.validator( eles.norm_hob, eles.err5, eles.errTxt5 ) &&
		eles.ucolor.validator( eles.norm_color, eles.err6, eles.errTxt6 )
	) {
		eles.form.submit();
	}
});
</script>
