validator验证控件使用代码_表单特效

function validator(obj,option){//验证对象
var self = this;
if(!(self instanceof validator))
return new validator(obj,option);
self.source={'mobile':'^(13|14|15|18)[0-9]{9}$','postcode':'^\\d{6}$','integer':'^-?\\d*$','email':'^\\w+((-\\w+)|(\\.\\w+))*\\@[A-Za-z0-9]+((\\.|-)[A-Za-z0-9]+)*\\.[A-Za-z0-9]+$','url':'^http[s]?:\\/\\/([\\w-]+\\.)+[\\w-]+([\\w-./?%&=]*)?$'};

self.type=self.source[i];
}
self.tag=2;

self.init(obj);
}
validator.prototype.init=function(o){
