从代码中的其他地方调用JQuery事件作为函数...?

好的,非常直接的JQuery问题,我正在努力寻找答案:

我有一个在按钮点击时调用的JQuery事件:

$(document).ready(function(){
        resetForms('reservation');
        $('#form-reservation').submit(function(event){ 
            event.preventDefault();  //the page will no longer refresh on form submit.
            var resCheck = $(this).find('input[class="reservationid"]').val(); //now we have the reservation ID, let's perform our check.
            document.cancel_res.cancel_agree.checked = false;
            //document.cancel_res.cancel_agree.disabled = false;
            document.cancel_res.cancel_button.disabled=true;
            document.form_reservation.search_button.value="Searching...";
            document.form_reservation.search_button.disabled=true;
            $.ajax({ 
                url: 'inc/searchres.php', 
                type: 'POST',
                data: 'resid='+resCheck, 
                success: function(data){  //data is all the info being returned from the php file 
                    resetForms('reservation');  //clear forms
                    document.form_reservation.search_button.value="Search Reservation";
                    document.form_reservation.search_button.disabled=false;
                    $('#reservation-id').val(resCheck);  //add read ID back into text box
                    var jsonData = $.parseJSON(data);
                    //BLAH BLAH BLAH BLAH
                }
            });
        });
    });

该功能完美无缺......但是,无论如何在不使用提交事件的情况下调用此函数?我尝试在$('#form-reservation').submit(function(event){调用后取出所有内容并将其放在一个单独的函数中,然后从submit事件中调用该函数。然而,无论出于何种原因,这都失败了。

基本上,我希望提交事件仍然触发此功能,但我也希望能够在其他情况下调用整个函数。提前谢谢!

实际上非常简单:

var MyFunc = function(event){ 
            typeof event !== 'undefined' ? event.preventDefault() : false;  //the page will no longer refresh on form submit.
            var resCheck = $(this).find('input[class="reservationid"]').val(); //now we have the reservation ID, let's perform our check.
            document.cancel_res.cancel_agree.checked = false;
            //document.cancel_res.cancel_agree.disabled = false;
            document.cancel_res.cancel_button.disabled=true;
            document.form_reservation.search_button.value="Searching...";
            document.form_reservation.search_button.disabled=true;
            $.ajax({ 
                url: 'inc/searchres.php', 
                type: 'POST',
                data: 'resid='+resCheck, 
                success: function(data){  //data is all the info being returned from the php file 
                    resetForms('reservation');  //clear forms
                    document.form_reservation.search_button.value="Search Reservation";
                    document.form_reservation.search_button.disabled=false;
                    $('#reservation-id').val(resCheck);  //add read ID back into text box
                    var jsonData = $.parseJSON(data);
                    //BLAH BLAH BLAH BLAH
                }
            }

$(document).ready(function(){
        resetForms('reservation');
        $('#form-reservation').submit(MyFunc); //this calls on submit
    });

//this calls without need of a submit
MyFunc();

我只是触发处理程序。

$("#form-reservation").triggerHandler("submit");

http://api.jquery.com/triggerHandler/

根据api文档,这不会导致表单提交,它只是运行绑定到该事件的处理程序。
