submitHandler: 通過驗證后運行的函數,里面要加上表單提交的函 數,否則表單不會提交$(".selector").validate({ submitHandler:function(form) { $(form).ajaxSubmit(); //用Jquery Form的函數 } })Jquery Validate error 錯誤提示dom.errorPlacement：Callback Default: 把錯誤信息放在驗證的元素后面指明錯誤放置的位置，默認情況是：error.appendTo(element.parent());即把錯誤信息放在驗證的元素后面errorPlacement: function(error, element) {error.appendTo(element.parent());}
