Answer 1

在我将项目从Angular 5更新到6之后,我遇到了同样的问题.我在Derek Brown的评论的帮助下找到了解决方案.解决方案是在polyfill.ts文件中添加以下内容:

if (!Element.prototype.matches) {
  Element.prototype.matches = Element.prototype.msMatchesSelector;
}

Answer 2

对于使用Angular 6和7（打字稿）的用户，应使用以下命令修改Sanjay Gupta的答案：

if (!Element.prototype.matches) {
  Element.prototype.matches = (<any>Element.prototype).msMatchesSelector ||
    Element.prototype.webkitMatchesSelector;
}

强制转换（实际上是取消类型化）允许编译器解析未定义的方法。

Answer 3

看起来IE matches使用非标准名称(源)实现该功能.该链接包括一个polyfill,它将定义该matches函数,以便可以在IE上使用.
