jQuery UI对话框+验证

Question

单击"保存"时,我无法使用Jquery Validate验证jQuery UI对话框.

这是我创建Jquery对话框的代码.它从目标href URL加载对话框:

$(document).ready(dialogForms);

function dialogForms() {
  $('a.dialog-form').click(function() {
    var a = $(this);
    $.get(a.attr('href'),function(resp){
      var dialog = $('<div>').attr('id','formDialog').html($(resp).find('form:first').parent('div').html());
      $('body').append(dialog);
      dialog.find(':submit').hide();
      dialog.find('#return').hide();
      dialog.dialog({
        title: a.attr('title') ? a.attr('title') : '',
        modal: true,
        buttons: {
          'Save': function() {submitFormWithAjax($(this).find('form'));},
          'Cancel': function() {$(this).dialog('close');}
        },
        close: function() {$(this).remove();},
        width: 'auto'
      });
    }, 'html');
    return false;
  });
}

function submitFormWithAjax(form) {
    form = $(form);
    $.ajax({
        beforeSend: function(data) {
            //alert("beforesend");
            form.validate();
        },
        url: form.attr('action'),
        data: form.serialize(),
        type: (form.attr('method')),
        dataType: 'text',
        error: function(data) {
            alert(data);
            $('#result').html(data);
        },
        success: function(data) {
            //alert("success");
            $('#result').html(data);
            setTimeout("reloadPage()", 500);
        }
    });
  return false;
}

将beforeSend被调用,但它似乎并没有调用validate方法,它位于从对话框称为父页面上.

        $(document).ready(function() {
            $("#event_form").validate({
                rules: {
                    Name: {
                        required: true
                    },
                    Category: {
                        required: true
                    }
                },
                messages: {
                    Name: "Please enter an event name",
                    Category: "Please choose a category"
                },
                submitHandler: function(form) {
                    alert("validated");
                    //                    $('#loading_1').show();
                    //                    $('#proceed_c').hide();
                    //                    $(form).ajaxSubmit();
                    //                    //form.submit();
                },
                errorPlacement: function(error, element) {
                    error.appendTo(element.next(".status"));
                }
            });

}

该问题是与beforeSend内submitFormWithAjax function,该位置$("#event_form").validate或submitHandler: function(form)内呢？任何帮助将不胜感激.

初始化jQueryUI对话框时,它会修改DOM,整个对话框从页面中的位置中取出并插入到</body>标记之前.你可以用Firebug看到这个.这会导致Validate出现问题,因为现在表单为空.要解决此问题,请在对话框的open事件中将其附加到表单.这听起来很古怪,但相信我,它的工作:)

dialog.dialog({
    title: a.attr('title') ? a.attr('title') : '',
    modal: true,
    buttons: {
      'Save': function() {submitFormWithAjax($(this).find('form'));},
      'Cancel': function() {$(this).dialog('close');}
    },
    close: function() {$(this).remove();},
    open: function(){
        $(this).parent().appendTo($('#event_form'));
    },
    width: 'auto'
  });

编辑:

<form id='event_form'>
  <div id="dialog" title="DialogTitle"> 
  </div>
</form>
