JQuery验证在页面刷新后不起作用(Jquery Mobile)

我有一个 Jquery Mobile / asp.net mvc4应用程序.在第一页之后,Jquery移动使用Ajax请求调用后续页面.现在,我使用JQuery验证器插件在我的表单上执行验证,第一次验证工作正常(即使用ajax调用加载时),但是当页面刷新/重新加载时,验证不起作用.知道为什么会这样吗？由于这是一个移动Web应用程序,因此用户可能会刷新页面.

这是我用过的验证码：

<script type="text/javascript">    
// jquery form validation function
$(function () {
    $("#permissionrequestForm").validate({
        errorPlacement: function (error,element) {
            if (element.attr("name") === "fromTimeHH" || element.attr("name") === "toTimeHH" || element.attr("name") === "fromTimeMM" || element.attr("name") === "toTimeMM") {
                error.insertAfter($(element).parent());
            } else {
                error.insertAfter(element);
            }
        },//custom validation messages
        messages: {
            fromDate: "Choose From Date",toDate: " Choose To Date",fromTimeHH: "Choose From Time",fromTimeMM: "",toTimeHH: "Choose To Time",toTimeMM: "",permissionTypeOne: "SELEct Permission Type",permissionTypeTwo: "SELEct Permission Type",approverList: "SELEct Approver",reasonLeave: "Enter a Valid Reason"
        }
    });
});

$(document).ready(function() {    

});

$(function () {

});

$('#index').live('pageshow',function(e,data){    
    $.validator.addMethod("valueNotEquals",function(value,element,arg){
        return arg != value;
    },"");

    $("#form1").validate({
        rules: {
            SELEct_list : {valueNotEquals: "default"},},messages: {  
            SELEct_list : { valueNotEquals: "You must SELEct a value" }
        },submitHandler: function(form) {
            alert($('#form1').valid());
            form.submit();
        }
    });   
});
