Angular ng-bootstrap tabset 字段不工作

Question

    {
  "name": "ModalWindow",
  "version": "1.0.0",
  "repository": {
    "type": "git",
    "url": ""
  },
  "scripts": {

    "zone.js": "^0.8.26"
  },
  "devDependencies": {
    "@ng-bootstrap/ng-bootstrap": "^1.1.1",
    "@types/node": "^10.0.4",
    "angular2-template-loader": "^0.6.2",
    "css-loader": "^0.28.11",
    "html-webpack-plugin": "^3.2.0",
    "less": "^3.0.4",

    "webpack": "4.8.1",
    "webpack-cli": "^2.1.3",
    "webpack-dev-server": "3.1.4"
  }
}

这是我的 package.json，我不明白哪里出了问题，但 ng-bootstrap 中的标签集无法正常工作。

Answer 1

最新版本 4.0.0 和您在 package.json 中使用的版本(即 ^1.1.1)之间的主要区别在于，在最新版本中没有必要导入NgbModule作为NgbModule.forRoot() .例如-

此代码适用于版本 4.x.x

@NgModule({
  imports: [BrowserModule, FormsModule, ReactiveFormsModule, HttpClientModule, NgbModule],
  declarations: [....],
  bootstrap: [...]
})

但是如果你导入NgbModule如上所示，在您使用的 1.1.1 版本中，您将得到以下错误

ERROR Error: StaticInjectorError(AppModule)[NgbTabset -> NgbTabsetConfig]: StaticInjectorError(Platform: core)[NgbTabset -> NgbTabsetConfig]: NullInjectorError: No provider for NgbTabsetConfig!

那是因为低版本需要用.forRoot()在您的根模块中，以使其在您应用程序的所有其他模块和组件中可用。

因此对于您使用的版本 1.1.1，您需要在根模块中使用以下代码 app.module.ts

此代码适用于 1.1.1 版本

@NgModule({
  imports: [BrowserModule, FormsModule, ReactiveFormsModule, HttpClientModule, NgbModule.forRoot()],
  declarations: [AppComponent, NgbdTabsetBasic],
  bootstrap: [AppComponent]
})

这是 Angular 5 和您正在使用的 ng-bootstrap 版本 1.1.1 的完整示例 -

package.json(和你用的一样)

  "version": "1.0.0",
  "repository": {
    "type": "git",

  },

注意事项:

我们需要添加 Bootstrap 4.0 css 作为依赖。可以通过以下两种方式添加 css - 1.添加一个<link>在 index.html 中使用样式表标记页 2. 如果您使用的是 angular-cli，则可以将其添加到 styles 中节.angular-cli.json像

这样的文件

"styles": [
      "../node_modules/bootstrap/dist/css/bootstrap.min.css"
   ]

这是一个完整的工作演示 https://stackblitz.com/edit/angular-wfkcak

更新:通过您的 stackblitz 链接后，我发现您忘记添加 bootstrap 4 CSS 文件。我已将其添加到 index.html 中文件。

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

您也可以将其添加到 angular.json (对于 Angular 6 )或 .angular-cli.json (对于 Angular 5 )在 styles 下适用于您上面提到的数组。

这是更新的 stackblitz https://stackblitz.com/edit/angular-gmedf1
