Question

我的HTML和JavaScript代码使用fieldset来改变步骤形式。我希望在每个fieldset都有自己的表单标签，所以当我在1st fieldset中提交时它会改为第2个fieldset

这是我的HTML代码

<div class="formhandler">
<fieldset>
    1

    <form>
        <input type="text">
        <?php 
            echo form_button('previous', 'Kembali', array('class'=>'previous action-button'));
            echo form_submit('submit', 'Next', array('class'=>'next action-button')); 
        ?>
    </form>
</fieldset>

<fieldset>
    2

    <form>
        <input type="text">
        <?php 
            echo form_button('previous', 'Kembali', array('class'=>'previous action-button'));
            echo form_submit('submit', 'Next', array('class'=>'next action-button')); 
        ?>
    </form>
</fieldset>

请帮我解决这个问题

Answer 1

您可以为每个字段集执行javascript调用自定义ajax请求，具体取决于步骤，在客户端验证此字段。

因为如果您不使用ajax，页面将会刷新，您将失去该步骤。
