3 个答案:

答案 0 :(得分:17)

将项目从Angular 5更新到6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;
}

答案 1 :(得分:7)

看起来IE使用非标准名称(source)实现matches函数。该链接包含一个polyfill,它将定义matches函数,以便可以在IE上使用。

答案 2 :(得分:5)

对于使用Angular 6和7(打字稿)的用户,您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(嗯,取消类型化,实际上)允许编译器分析未定义的方法。
