JS文件出现在源代码中，但是Javascript没有执行？

Question

我在我的WordPress网站上添加了CSS响应式动画手风琴式组合。我的JS文件显示在源代码中，但效果仍然不起作用。出于某种原因，javascript没有执行。

这是我的JS（/inc/js/accordion.js）

＆＃13;

此处它位于codepen并且在那里工作正常，但是如果您运行上面的代码段，您会发现手风琴缺少codepen上的功能。

虽然我已经将codepen中的代码复制并粘贴到我的JS文件中，但效果并不适用于我的WordPress网站或上面的堆栈溢出代码段。由于JS文件显示在我的WordPress网站的源代码中，我无法弄清楚它为什么没有执行。

问题可能在于我的JS文件是如何落入DOM结构的？我不知道。

html标记和CSS一样（一些微小的变化）。

任何了解JS的人都可以帮助我吗？

Answer 1

您的javascript未运行，因为Wordpress与其加载的其他库存在兼容性问题。要解决此问题，您可以查看此link。

背后的想法是WordPress附带的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的全局$快捷方式不可用，因此您可以使用：

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

这只是替换jQuery的$。

如果您确实想要使用$，可以将其包含在下面的代码中。

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
});
