第一次发帖。我提前感谢任何帮助。我真的很感激。
我目前正在使用wordpress主题搜索世界各地的别墅，我希望添加一个重置按钮，清除字段，下拉菜单和自定义字段应用填充的复选框。正常的重置按钮不起作用，因为我正在教我自己的PHP我不知所措。这是该页面的链接，我将粘贴一些代码，以便您了解我正在查看的内容。
我非常感谢任何帮助，因为主题作者一直在吹我。

答案 0 :(得分：0)
需要修改一行代码
<a href="javascript:document.getElementById('form_[form_key]').reset();" autocomplete="off">Reset Form</a>
该元素不存在，表单有一个名为property-search-form的类，您可以将其用作选择器。
所以用
之类的东西替换这一行<a href="javascript:document.getElementsByClassName('property-search-form').reset();" autocomplete="off">Reset Form</a>
