JS文件在源代码中显示，但JavaScript未执行？

Question

我正在为我的WordPress网站添加一个CSS响应式动画手风琴式组合。我的JS文件出现在源代码中，但效果仍然不起作用。出于某种原因，JavaScript未执行。

这里是我的JS（/inc/js/accordion.js）

/*! 
 
* classie - class helper functions 
 
* from bonzo https://github.com/ded/bonzo 
 
* 
 
* classie.has(elem, 'my-class') -> true/false 
 
* classie.add(elem, 'my-new-class') 
 
* classie.remove(elem, 'my-unwanted-class') 
 
* classie.toggle(elem, 'my-class')

这是codepen，它工作正常那里，但如果你运行上面的代码中你”会发现手风琴缺少codepen上的功能。

这些效果不适用于我的WordPress站点或上述堆栈溢出片段，尽管我已将代码从codepen复制并粘贴到我的JS文件中。由于JS文件显示在我的WordPress网站的源代码中，我无法弄清楚为什么它没有执行。

难道问题在于我的JS文件如何落入DOM结构？我不知道。

html标记是一样的，因为是CSS（几个微小的变化）。

任何人都知道他们与JS的方式帮助我在这里？

Answer 1

您的JavaScript未运行，因为WordPress的与它加载其他库的兼容性问题。要解决它，你可以看看这个link。

它背后的想法是WordPress中包含的jQuery库设置为noConflict（）模式。这是为了防止WordPress可以链接的其他JavaScript库的兼容性问题（我直接引用它们）。

在noConflict（）模式下，jQuery的全球$快捷方式不可用，那么你可以使用：

jQuery(document).ready(function(){ 
    jQuery(#somefunction) ... 
}); 

这只是一个替代$的jQuery的问题。

如果你确实想要使用你的$，你可以将它包装在下面的代码中。

jQuery(document).ready(function($) { 
    // Inside of this function, $() will work as an alias for jQuery() 
    // and other libraries also using $ will not be accessible under this shortcut 
});
