文件的导入以及其他导入到其他地方的其他地方...
答案 0 :(得分：1)
您在模板中调用了openFullDetailDialog(r.number)，但在组件中只有openFullDetailDialog()没有参数。
答案 1 :(得分：0)
由于您通过点击事件传递数据，您需要将MAT_DIALOG_DATA导入my-file.component.ts
答案 2 :(得分：0)
我发现我收到了控制台错误：
错误：找不到RaceDetailPopupComponent的组件工厂。你有没有把它添加到@ NgModule.entryComponents？
经过一段谷歌搜索后，我发现我需要将RaceDetailPopupComponent添加到entryComponents:[]部分下的'app.module.ts'文件中。
我的对话框现在可以正常打开。
NB。我不知道为什么会发生这种情况，因为我已经有两个从同一位置打开但具有不同输出的对话框...它们没有这个entryComponents导入。
