jquery - 如何在不提交的情况下验证表单并使用 jquery mobile 和 Jquery 验证转到其他页面？

Question

因此，我正在尝试验证一个 JQM 表单，该表单有 4 个部分并分为不同的页面，因此在验证第一部分后，如果表单有效，我想转到第二部分。我正在尝试使用 JQuery.validate 插件进行验证，但它不会以任何方式响应表单。

PS:必须带有 JQuery.validation 插件

 <div data-role="page" id="page2" data-add-back-btn="true">

阶梯形式有多种方法。

当我创建多步骤表单时，我使用一组独特的 <form>每个部分的标签。然后我使用 the .valid() method在进入下一个部分之前测试该部分。 (不要忘记首先初始化插件；在 DOM 上的所有表单上调用 .validate() 。)

然后在最后一部分，我使用 .serialize()在每个表单上并将它们连接成要提交的数据查询字符串。

类似这样的事情...

$(document).on('pageinit', function() { // dom ready handler for jQuery Mobile

    $('#form1').validate({ // initialize form 1
        // rules
    });

    $('#gotoStep2').on('click', function() { // go to step 2
        if ($('#form1').valid()) {
            // code to reveal step 2 and hide step 1
        }
    });

    $('#form2').validate({ // initialize form 2
        // rules
    });

    $('#gotoStep3').on('click', function() { // go to step 3
        if ($('#form2').valid()) {
            // code to reveal step 3 and hide step 2
        }
    });

    $('#form3').validate({ initialize form 3
        // rules,
        submitHandler: function (form) {
           // serialize and join data for all forms
           var data = $('#form1').serialize() + '&' + $('#form2').serialize() + '&' + $(form).serialize()
           // ajax submit
           return false; // block regular form submit action
        }
    });

    // there is no third click handler since the plugin takes care of this 
    // with the built-in submitHandler callback function on the last form.

});

重要的是要记住我的 click上面的处理程序没有使用 type="submit"纽扣。这些是常规按钮，位于form外部标签或 type="button" .

只有最后一个表单上的按钮是常规按钮 type="submit"按钮。那是因为我正在利用插件的内置 submitHandler仅在最后一个表单上使用回调函数。

顺便说一句，请注意我如何替换您过时的 .bind()与更现代的.on()方法。
