submitHandler: 通过验证后运行的函数,里面要加上表单提交的函 数,否则表单不会提交$(".selector").validate({ submitHandler:function(form) { $(form).ajaxSubmit(); //用Jquery Form的函数 } })Jquery Validate error 错误提示dom.errorPlacement：Callback Default: 把错误信息放在验证的元素后面指明错误放置的位置，默认情况是：error.appendTo(element.parent());即把错误信息放在验证的元素后面errorPlacement: function(error, element) {error.appendTo(element.parent());}
