jquery.validate remote 和 自定义验证方法

$(function(){

var validator = $("#enterRegForm").validate({
debug:false, //调试模式取消submit的默认提交功能
//errorClass: "error",//默认为错误的样式类为：error
//validClass: "check",//验证成功后的样式，默认字符串valid
focusInvalid: true,//表单提交时,焦点会指向第一个没有通过验证的域
//focusCleanup:true;//焦点指向错误域时，隐藏错误信息，不可与focusInvalid一起使用！
onkeyup: true,
errorElement: "div",
submitHandler: function(form){ //表单提交句柄,为一回调函数，带一个参数：form
form.submit(); //提交表单
},
