【问题描述】：
我有一个 Wordpress 页面，当有人单击复选框时，我正在运行一些 jQuery 来显示和隐藏 2 个输入字段。问题是这段代码在我的主页上完美运行，但是当我尝试在子页面上做同样的事情（使用完全相同的 html 结构和 jquery）时，它不再有效。并不是说文件没有被加载，因为 jQuery 文件的一部分在该页面上运行良好，我什至在文件末尾有一个 console.log 以显示文件已完全加载。
www.yogagids.nl 是主页，当您单击复选框“Evenementen”时，会显示 2 个日期选择器字段，取消选择它并隐藏它们。它应该是这样工作的。
www.yogagids.nl/listings 是这个不起作用的页面。同样的故事，单击“evenementen”复选框，2个日期选择器字段应该显示和隐藏。但是在这个页面上什么都没有发生。
我真的很茫然，任何和所有的帮助都将不胜感激。
这是此页面上运行的所有代码，实际文件较大但我无法发布那么多字符。

【问题讨论】：
-
这似乎是加载顺序问题。在第一次运行代码时未找到该复选框。如果在控制台中我手动运行 jQuery(".listingTypeSelect input[value=event]").change(function() {console.log('clicked');});点击处理程序附加到该复选框。我不知道页面是如何生成的，但是如果您可以访问右侧部分呈现的回调，您应该使用它来调用此脚本。要测试这个理论，请添加一个 console.log(jQuery(".listingTypeSelect input[value=event]")) 并查看它是否返回任何内容。
