Demo:
$(".demoform").Validform({//$(".demoform")指明是哪一表单需要验证,名称需加在form表单上;
btnSubmit:"#btn_sub", //#btn_sub是该表单下要绑定点击提交表单事件的按钮;如果form内含有submit按钮该参数可省略;
btnReset:".btn_reset",//可选项 .btn_reset是该表单下要绑定点击重置表单事件的按钮;
tiptype:1, //可选项 1=>pop box,2=>side tip，默认为1，也可以传入一个function函数，自定义提示信息的显示方式（可以实现你想要的任何效果，具体参见demo页）;
ignoreHidden:false,//可选项 true | false 默认为false，当为true时对:hidden的表单元素将不做验证;
dragonfly:false,//可选项 true | false 默认false，当为true时，值为空时不做验证；
tipSweep:true,//可选项 true | false 默认为false，当true时提示信息将只会在表单提交时触发显示，各表单元素blur时不会被触发显示;
showAllError:false,//可选项 true | false，true：提交表单时所有错误提示信息都会显示，false：一碰到验证不通过的就停止检测后面的元素，只显示该元素的错误信息;
postonce:true, //可选项 是否开启网速慢时的二次提交防御，true开启，不填则默认关闭;
ajaxPost:true, //使用ajax方式提交表单数据，默认false，提交地址就是action指定地址;
datatype:{//传入自定义datatype类型，可以是正则，也可以是函数（函数内会传入一个参数）;
"*6-20": /^[^\s]{6,20}$/,
"z2-4" : /^[\u4E00-\u9FA5\uf900-\ufa2d]{2,4}$/,
"username":function(gets,obj,curform,regxp){
//参数gets是获取到的表单元素值，obj为当前表单元素，curform为当前验证的表单，regxp为内置的一些正则表达式的引用;
var reg1=/^[\w\.]{4,16}$/,
reg2=/^[\u4E00-\u9FA5\uf900-\ufa2d]{2,8}$/;
				
if(reg1.test(gets)){return true;}
if(reg2.test(gets)){return true;}
return false;
				
//注意return可以返回true 或 false 或 字符串文字，true表示验证通过，返回字符串表示验证失败，字符串作为错误提示显示，返回false则用errmsg或默认的错误提示;
},
"phone":function(){
// 5.0 版本之后，要实现二选一的验证效果，datatype 的名称 不 需要以 "option_" 开头;	
}
},
usePlugin:{
swfupload:{},
datepicker:{},
passwordstrength:{},
jqtransform:{
selector:"select,input"
}
},
beforeCheck:function(curform){
//在表单提交执行验证之前执行的函数，curform参数是当前表单对象。
//这里明确return false的话将不会继续执行验证操作;	
},
beforeSubmit:function(curform){
//在验证成功后，表单提交前执行的函数，curform参数是当前表单对象。
//这里明确return false的话表单将不会提交;	
},
callback:function(data){
//返回数据data是json格式，{"info":"demo info","status":"y"}
//info: 输出提示信息;
//status: 返回提交数据的状态,是否提交成功。如可以用"y"表示提交成功，"n"表示提交失败，在ajax_post.php文件返回数据里自定字符，主要用在callback函数里根据该值执行相应的回调操作;
//你也可以在ajax_post.php文件返回更多信息在这里获取，进行相应操作；
			
//这里执行回调操作;
//注意：如果不是ajax方式提交表单，传入callback，这时data参数是当前表单对象，回调函数会在表单验证全部通过后执行，然后判断是否提交表单，如果callback里明确return false，则表单不会提交，如果return true或没有return，则会提交表单。
}
});
	
Validform对象的方法和属性：
tipmsg：自定义提示信息，通过修改Validform对象的这个属性值来让同一个页面的不同表单使用不同的提示文字；
dataType：获取内置的一些正则；
eq(n)：获取Validform对象的第n个元素;
ajaxPost(flag,sync)：以ajax方式提交表单。flag为true时，跳过验证直接提交，sync为true时将以同步的方式进行ajax提交；
abort()：终止ajax的提交；
submitForm(flag)：以参数里设置的方式提交表单，flag为true时，跳过验证直接提交；
resetForm()：重置表单；
resetStatus()：重置表单的提交状态。传入了postonce参数的话，表单成功提交后状态会设置为"posted"，重置提交状态可以让表单继续可以提交；
getStatus()：获取表单的提交状态，normal：未提交，posting：正在提交，posted：已成功提交过；
setStatus(status)：设置表单的提交状态，可以设置normal，posting，posted三种状态，不传参则设置状态为posting，这个状态表单可以验证，但不能提交；
ignore(selector)：忽略对所选择对象的验证；
unignore(selector)：将ignore方法所忽略验证的对象重新获取验证效果；
addRule(rule)：可以通过Validform对象的这个方法来给表单元素绑定验证规则；
