jQuery模式确认对话框后如何提交表单？

Question

该脚本将打开一个jQuery对话框/模式，以在提交表单之前请求验证，但是当用户单击模式窗口中的“提交”按钮时，将不会发生任何事情。 Firebug揭示问题出在包含“ document.leaveReq.submit（）;”的行中 我对jQuery和javascript很陌生，并且已经为此苦苦挣扎了几天。 非常感谢您的任何帮助。

$(document).ready(function() {

    // jQuery UI Dialog    
    $('#dialog').dialog({
        autoOpen: false,
        width: 400,
        modal: true,
        resizable: false,
        buttons: {
            "Submit": function() {
                document.leaveReq.submit();
                return true;
            },
            "Cancel": function() {
                $(this).dialog("close");
                return false;
            }
        }
    });
    $('#formerror').dialog({
        autoOpen: false,
        modal: true,
        resizable: false,
        buttons: {
            "Back": function() {
                $(this).dialog("close");
                return false;
            }
        }
    });

    $('#verify').click(function(e){
        e.preventDefault();
        if( !$("input#from").val() || !$("input#to").val()){
            $("span#error-message").html('Provide a starting and ending date.');
            $('#formerror').dialog('open');
        } else if( $("input#amount").val() == 0 ){
            $('#formerror').dialog('open');
            $("span#error-message").html('Provide the number of units that you will use.');
        } else if( !$("textarea#description").val() ){
            $("span#error-message").html('Provide the reason for this leave request.');
            $('#formerror').dialog('open');
        } else {
                $("span#leavedescriptionidentification").html(document.getElementById('leave_description_identification').options[document.getElementById('leave_description_identification').selectedIndex].value);

在对话框的Submit函数中，尝试：

"Submit": function() {
    $('form#leaveReq').submit();
    return true;
},
