未应用烤面包机样式
Toaster styling not being applied
在初始加载时,我得到错误 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(除非修复它恰好解决了其他问题,我暗暗怀疑它会) .
主要问题出现在我尝试弹出吐司时,吐司文本与我想要的淡入淡出 in/out 动画一起显示,但是 none of the styling I expect to see
我在 component.html
中有一个 toaster-container
,我导入 ToasterModule
并将 ToasterService
列为 module.ts
中的提供商,我有 toaster.css
在 index.html
中导入。这些是我在其他类似文章中看到的潜在解决方案,虽然它们确实让我在吐司时出现文本,但它们并没有改变这些当前问题中的任何一个。
如果您在下面的 angular2-toaster
实现中看到错误,请告诉我,我以前从未使用过它,所以很可能某些东西就在我眼皮底下,只是我没有看到它.我还将这段代码与工作中完成的其他项目进行了比较,代码与我阅读过的需要匹配的地方相匹配,但其他项目正确显示了 toast 样式。
我的代码如下:
rollPlan.module.ts:
import {NgModule} from '@angular/core';
import {BrowserModule} from '@angular/platform-browser';
import {Http, HttpModule} from '@angular/http';
import {FormsModule} from '@angular/forms';

export class RollPlanComponent implements OnInit {
// Below are for toaster alerts
toasterconfig: ToasterConfig = new ToasterConfig({
animation: 'fade',
positionClass: 'toast-top-right'
});
constructor(private httpService: HTTPRollPlanService,
private toasterService: ToasterService) {
}
popToast(typ: string, titl: string, bod: string) {
var toast: Toast = {
type: typ,
title: titl,
body: bod
};
this.toasterService.pop(toast);
}
/* There is more code here to implement ag-grid normally, but for this error
I chose to exclude it to provide the minimal/complete/verifiable example */
}
rollPlan.component.html:

您的问题有一些潜在问题(和解决方案)。
首先,有一个新的 5.0.0 版本的 angular2-toaster 可用,它将通过提供 ToasterModule.forRoot()
实现来最终解决您的 No Toaster Containers have been initialized to receive toasts
错误。
要使用此版本,只需升级到 5.0.0 并将您的 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]
})
这将确保单例烤面包机服务与包含的烤面包机容器相结合。如果你不能升级你的库版本,你应该省略根提供者中的 ToasterService 包含,只将它包含在你的组件的提供者中。
对于您的问题,缺少样式,您通常不能在 html 入口点直接 bootstrap node_modules css 文件。
因此,您有两个选择:
- 从CDN加载文件:https://npmcdn.com/angular2-toaster@5.0.0/toaster.min.css
- 通过您正在使用的 css 预处理器将文件加载到您的 style.css 或其他根 css/scss 文件中。
@import 'node_modules/angular2-toaster/toaster'
当我将版本更新到 "angular2-toaster": "^8.0.0"
时,烤面包机背景样式不起作用。
像这样:
我用Angular 7
和bootstrap
一开始我在bootstrap.min.css
之前导入了toaster.min.css
,所以背景色没有效果
通过在 angular.json
中的 bootstrap.min.css
之后导入 toaster.min.css
来解决,例如:
"styles": [
"src/styles.scss",
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"node_modules/angular2-toaster/toaster.min.css"
]
您可以像
一样加载style.css
中的文件
@import "~angular2-toaster/toaster.min.css";
添加到angular.json后记得重启web进程,如果使用Visual Studio需要关闭,否则重新运行ng serve
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"node_modules/ngx-toastr/toastr.css",
"src/styles.css"
],
在初始加载时,我得到错误 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(除非修复它恰好解决了其他问题,我暗暗怀疑它会) .
