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

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。
