如何将Internet Explorer 10支持添加到简单的VueJs组件?

标签: javascript internet-explorer vue.js internet-explorer-10

我正在构建一个简单的VueJs组件,该组件根本无法在IE 10中呈现。

背景:vue组件是公司事件的列表,它支持基本的筛选和排序。不幸的是,我必须支持IE10。我没有使用babel,但尝试将其用于解决此问题-无效

我遇到的错误是'city' is undefined。 IE10是唯一遇到此问题的浏览器。

这里是仅相关代码的代码笔。我添加了评论以澄清正在发生的事情。 https://codepen.io/thewebtech/pen/zJbeVy

这里只是JS(有关完整代码和更好的上下文,请参见codepen):

我尝试过的故障排除步骤:

  • 使用了babel,尽管我的代码本来不是这样写的。
  • 我使用了babel-polyfill-似乎没有效果。
  • 我试图将主体中script标记中的js放入主JS文件中,以查看由于某种原因在html中的代码之前加载js文件是否存在问题。没有效果。

认为的原因可能是该问题:

  • IE10不喜欢像我一样将属性值分配给对象。不确定。只是一个猜测,我想不出另一种方式来做。

IE 10控制台错误和Codepen渲染失败(如果有帮助的话)的屏幕截图。

如果您有任何想法但又没有测试的方法我可以测试任何更改,然后将我看到的内容和控制台的记录发回记录,如果有错误。

如果需要,我愿意以其他方式对此进行编码。 我真的很感谢任何人愿意提供的帮助。我不认为自己是JavaScript专家,也不是Vue专家。如果您看到我正在做的事情很容易引起问题,请指出来,只是建设性。 “那样做糟透了!”除了YouTube评论垃圾邮件已泄漏到stackoverflow之外,它什么也没教给我。

谢谢!

答案 0 :(得分:1)

我自己发布答案,其他人也可能会遇到此问题,并且那里没有太多信息。

有两个问题。我的selectedCities和selectedStates数组最后有一个逗号。较新的浏览器不在乎,但是<= IE10会。

此外,还有VueJS问题。有人更新了Vue JS,以使用IE 10及更低版本不理解的新正则表达式字符串。解决方法是使用旧版本的VueJS或替换正则表达式。我在哪里找到此信息的说明:

感谢所有提供帮助的人。

特别感谢Pete Emerson和Kevin Leonard(他们通过HubSpot Dev Slack帮助我,发现了根本问题)!
