我正在开发一个Vue组件,它将通过CMS系统放置在多个网站上.我遇到的问题是即使我的js脚本加载顺序是正确的,有时我会收到此错误:

Uncaught ReferenceError: Vue is not defined
    at HTMLDocument.<anonymous>

Vue通过cdn加载,它位于组件代码之上.

所有的Vue代码都是这样运行的:

document.addEventListener("DOMContentLoaded", () => {
  // here is the Vue code
});

我甚至在DOMContentLoaded事件中添加了一个setTimeout(),但仍然没有做到这一点. window.onload = function()在所有情况下都不起作用.我还是经常遇到这个错误.脚本加载到正文中.

你知道它可以是另一种方法吗？我想确保在激活Vue代码的那一刻,Vue已加载并准备在页面上初始化.谢谢!

我有一个Meteor内置的应用程序.我在本地运行它,它也部署在服务器上.我刚刚发现Chrome上的应用程序不再运行了.我不确定,但可能唯一的区别是我的Chrome今天得到了更新.该应用程序在Firefox和IE Edge以及较旧的IE上运行良好.我查看了控制台,我有这些错误:

Exception in callback of async function: Error: Handler with name 'hookWithOptions' already exists.

上面的错误是针对localhost上的应用程序.

部署在服务器上的那个是2,3次提交后面有这些错误:

Exception in callback of async function: Error: Handler with name 'u' already exists.
