ngb-alert 仅适用于 type="success" 或无类型

Question

我有以下有效的代码。

<ngb-alert *ngIf="alertError" class="fade animate-show animate-hide"  (close)="alertError = false"><strong>{{ message }}</strong></ngb-alert>
<ngb-alert *ngIf="alertSuccess" class="animate-show animate-hide" type="success" (close)="alertSuccess = false"><strong>{{ message }}</strong></ngb-alert>

但是，如果我更改为以下内容，则不会

<ngb-alert *ngIf="alertError" class="fade animate-show animate-hide" type="danger" (close)="alertError = false"><strong>{{ message }}</strong></ngb-alert>
<ngb-alert *ngIf="alertSuccess" class="animate-show animate-hide" type="primary" (close)="alertSuccess = false"><strong>{{ message }}</strong></ngb-alert>

我的 package.json 是这样的。

 "dependencies": {
    "@angular/animations": "^4.3.4",
    "@angular/cdk": "^2.0.0-beta.8",
    "@angular/common": "^4.3.4",
    "@angular/core": "^4.3.4",

  },

    "ts-node": "^3.3.0",
    "tslint": "^5.5.0",
    "typescript": "^2.4.2"
  }

那么，请有专家告诉我这里有什么问题吗？为什么输入主要或危险将不起作用。

Answer 1

我遇到了类似的问题。我的问题是 Angular 认为我正在传递一个变量，从中读取类型。显然没有变量 titledprimary所以它失败了。改变事情以[type]="'primary'"完全解决问题。

<ngb-alert *ngIf="alertSuccess" class="animate-show animate-hide" [type]="'primary'" (close)="alertSuccess = false"><strong>{{ message }}</strong></ngb-alert>

Answer 2

我认为你只是不被允许使用这里的fade课程。

class="fade animate-show animate-hide"

如果我运行你的代码，它只会告诉我成功。但如果我删除该类fade，它会显示两条消息。

编辑

我将你的依赖项列表与我的进行了比较。

您是否尝试过更新您的库？
您可以从命令行运行它：

npm update -D && npm update -S

你有但我没有的依赖关系：

"angular-loader": "^1.6.5",
"font-awesome": "^4.7.0",
"primeng": "^4.1.3",
"screenshot-desktop": "^1.1.0",
"underscore": "^1.8.3"

我特别想知道第一个angular-loader。你知道它是用来做什么的吗？根据其文档，它是 Angular JS依赖项。
