jQuery 不会在开发站点上运行，但可以在在线代码编辑器上运行。找不到冲突

Question

我在使用 jQuery 时遇到问题，我可以让它在不同的测试环境中工作，但不能在我的开发站点上工作。我似乎无法找到冲突或导致冲突的原因。

它应该如何工作:当您将鼠标悬停在图标上时，它会更改上面的可见 div。我在这里工作:http://codepen.io/redbranchmedia/pen/dkiCB在这里:http://jsfiddle.net/nXzFX/

JavaScript:

    <script type="text/javascript">
$('.iconcontainer .icon').on(
{
    mouseenter: function()
    {
        $('.outercontainer .slidecontainer').addClass('hiddenslide');
        var show_slide = $(this).attr('data-slide');
        $('.' + show_slide).removeClass('hiddenslide');
    }
});
</script>

我无法让它在我的开发网站上工作(我想要的地方):http://talemetry.redbranchmedia.com/

我还在测试页上设置了它，因为我认为 slider 可能会干扰:http://talemetry.redbranchmedia.com/testing-page/

不幸的是，它在开发站点上的任何地方都不起作用，但它在 JSFiddle 和 CodePen 站点上运行。

我尝试过很多事情，包括: 从 Google Developer Libraries 调用不同版本的 jQuery 在网站内部调用 jQuery 将脚本中的“$”替换为“jQuery”(主题作者似乎已经这样做了)还有很多很多。

我不知道是什么导致了冲突并阻止了它的运行。我很感激任何帮助。

JSFiddle 和 CodePen 通常都会等待 dom 就绪事件来运行代码。

如果您的代码可以在这些网站上运行，我建议将您的代码包装在 $(document).ready() block 中，即:

$(document).ready(function(){
  $('.iconcontainer .icon').on(
  {
    mouseenter: function()
    {
        $('.outercontainer .slidecontainer').addClass('hiddenslide');
        var show_slide = $(this).attr('data-slide');
        $('.' + show_slide).removeClass('hiddenslide');
    }
  });
});
