在初始加载时,我得到了错误No Toaster Containers have been initialized to receive toasts.,这是一个问题,但不是这个问题的主题(除非修复它正好解决了其他问题,我很怀疑它会解决这些问题)。
主要的问题是,当我试图弹出祝酒词时,吐司文本会显示在我想要的淡入/退出动画中,但是没有我希望看到的造型。
我在component.html中有一个component.html,我在module.ts中导入ToasterModule和list ToasterService作为提供程序,并且在index.html中导入了toaster.css。这些都是我在其他类似文章中看到的潜在解决方案,虽然它们确实在我祝酒时出现了文本,但它们并没有改变当前的任何一个问题。
请告诉我,如果您在下面的angular2-toaster实现中看到了一个错误,我以前从未使用过它,所以很可能有什么东西就在我的眼皮底下,我只是没有看到它。我还将此代码与工作中正在执行的其他项目进行了比较,代码与我阅读过的代码匹配,但其他项目正确地显示了吐司样式。
我的代码如下:

你的问题有一些潜在的问题(和解决方案)。
首先,有一个新的5.0.0版本的angular2烤面包机,它将通过提供一个No Toaster Containers have been initialized to receive toasts实现来最终解决您的ToasterModule.forRoot()错误。
要使用此版本,只需升级到5.0.0并将angular2-toaster包含更改为:
@NgModule({
imports: [
BrowserModule,
HttpModule,
ToasterModule.forRoot(),
FormsModule,
AgGridModule.withComponents([]),
BrowserAnimationsModule //For the fade in/out animation
],
declarations: [
RollPlanComponent
],
providers: [], // note you no longer need to include ToasterService
bootstrap: [RollPlanComponent]
})这将确保单胎烤面包机服务与您的烤面包机容器包括在内。如果无法升级库的版本,则应该省略根提供程序中的ToasterService包含,而只将其包含在组件的提供程序中。
对于缺乏样式的问题,通常不能在html入口点直接引导node_modules css文件。
因此,您有两个选择:
@import 'node_modules/angular2-toaster/toaster'发布于 2019-07-15 04:01:01
当我将版本更新为"angular2-toaster": "^8.0.0"时,烤面包机的背景样式没有作用。
就像这样:

我使用Angular 7和bootstrap
一开始,我在toaster.min.css之前导入了bootstrap.min.css,所以背景色不起作用。
通过在toaster.min.css中导入bootstrap.min.css后的angular.json解决如下:
"styles": [
"src/styles.scss",
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"node_modules/angular2-toaster/toaster.min.css"
]发布于 2020-03-31 07:39:25
将其添加到angular.json后,请记住重新启动web进程,如果使用Visual,则需要关闭它,否则只需重新运行ng服务
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"node_modules/ngx-toastr/toastr.css",
"src/styles.css"
