srcmini第一次发布。非常感谢你提前提供的帮助。我真的很感激。
我目前正在使用wordpress主题来搜索世界各地的别墅, 并且我想添加一个重置按钮, 以清除由自定义字段应用填充的字段, 下拉列表和复选框。正常的重置按钮不起作用, 由于我正在自己动手自学PHP, 所以我很茫然。这是指向页面的链接, 我将粘贴一些代码, 以便你了解我正在查看的内容。
我非常感谢任何帮助, 因为主题作者一直让我失望。

有一行代码需要修改
<a href="javascript:document.getElementById('form_[form_key]').reset();" autocomplete="off">Reset Form</a>
该元素不存在, 该表单具有一个名为property-search-form的类, 你可以将其用作选择器。
所以用类似
<a href="javascript:document.getElementsByClassName('property-search-form').reset();" autocomplete="off">Reset Form</a>
