Question

我在模式中有一个表单，我想在表单提交给ajax db等之前验证。

我正在尝试验证格式$（“＃new_request_form”）。validate（{在保存按钮上。如果验证然后提交表单。

有人能告诉我我错过了什么吗？

提前致谢！

$(document).ready(dialogForms);
function dialogForms() {    
 $('a.menubutton').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.dialog({
        title: a.attr('title') ? a.attr('title') : '',

        buttons: {

编辑 - 它的作用

如果单击“保存”时没有执行任何操作，则模式会保持不变，即使填写表单，它也不会执行任何操作：

  'Save': function() {
            $("#new_request_form").validate({
             submitHandler: function(form) {
                 submitFormWithAjax($(this).find('form'));
                $(this).dialog('close');
             }
            });

        },

使用以下表单提交表单并按预期工作，只是没有验证：

 'Save': function() {
                 submitFormWithAjax($(this).find('form'));
                $(this).dialog('close');

            },

Answer 1

我想在调用submitHandler函数时，你传递了错误的选择器。 $（this）表示表单本身，因此不需要在其中找到表单。

所以替换此代码

submitFormWithAjax($(this).find('form'));

用

submitFormWithAjax($(this));

或者替代

submitFormWithAjax($("#new_request_form"));

这将解决您的问题。

使用模式form与ajax submitHandler进行jquery验证
