javascript - JS 文件显示在源代码中，但 Javascript 没有执行？

Question

我正在向我的 WordPress 网站添加 CSS 响应式动画 Accordion 式作品集。我的JS文件在源码中显示出来了，但是效果还是不行。由于某种原因，JavaScript 没有执行。

这是我的 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' )

这里是codepen它在那里工作得很好，但是如果你运行上面的代码片段，你会发现 Accordion 缺少 codepen 上的功能。

尽管我已将 codepen 中的代码复制并粘贴到我的 JS 文件中，但这些效果在我的 WordPress 网站或上面的堆栈溢出片段中不起作用。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。

问题可能出在我的 JS 文件如何落入 DOM 结构中吗？我不知道。

html 标记是相同的，CSS 也是如此(几个微小的变化)。

任何知道 JS 方法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。要解决这个问题，你可以看看这个link .

其背后的想法是将 WordPress 附带的 jQuery 库设置为 noConflict() 模式。这是为了防止与 WordPress 可以链接的其他 JavaScript 库出现兼容性问题(我直接引用它们)。

在noConflict()模式下，jQuery的全局$快捷方式不可用，因此可以使用:

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

这只是替换 jQuery 的 $ 的问题。

如果您真的非常想使用 $，您可以将其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
});
