[英]How do I add Internet Explorer 10 support to a simple VueJs component?
我正在构建一个简单的 VueJs 组件,它在 IE 10 中根本不呈现。
背景:Vue 组件是公司事件的列表,支持基本的过滤和排序。 不幸的是,我必须支持IE10。 我没有使用 babel,但试图用它来解决这个问题 - 没有效果
我得到的错误是'city' is undefined
。 IE10 是唯一遇到此问题的浏览器。
这是仅相关代码的 CodePen 。 我添加了评论以澄清正在发生的事情。 这里只是 JS(有关完整代码和更好的上下文,请参阅 CodePen):
/* Server rendered data */
var events = [{

我尝试过的故障排除步骤:
我认为可能导致问题的原因:IE10 不喜欢像我正在做的那样为对象分配属性值。 不确定这一点。 这只是一个猜测,我想不出另一种方法来做到这一点。
IE 10 控制台错误和 CodePen 中渲染失败的屏幕截图,以防万一。
如果您有任何想法但没有测试方法:我可以测试任何更改并发送我所看到的记录和控制台(如果有错误)。
自己发布答案,因为其他人也可能会遇到这个问题,并且没有太多信息。
有两个问题。 我的 selectedCities 和 selectedStates 数组的末尾有一个逗号。 较新的浏览器不关心这一点,但 <=IE10 关心。
此外还有一个 VueJS 问题。 有人更新了 Vue JS 以使用 IE 10 及以下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。 我找到此信息的来源的说明:
