/*
$.jbecool.validator类
支持多个表单的校验。
内置$.jbecool._validator对象，包含大量校验方法，可独立使用。

需要校验的表单需要设置校验器的唯一名称：
<form validatorName="vn1">...</form>
接下来撰写代码：
var vd1=$.jbecool.validators.getValidator("vn1");   //得到校验器
vd1.validate(); //进行校验
vd1.isAllValid; //判断是否全部合法

每个错误的提示可单独设定对应的label以显示错误，特别适合一个元素需要同时满足多个条件的情况
可通过byCallBack来实现调用某个函数判断是否合法，例如判断用户名是否已存在
