of-bootstrap 不显示工具提示

Question

我想显示工具提示。我去了 ng-bootstrap 并集成了该代码。获取控制台错误。

core.es5.js:1020 ERROR Error: Uncaught (in promise): Error: No provider for 
NgbTooltipConfig!
Error: No provider for NgbTooltipConfig!

at resolveDep (core.es5.js:11050)
at createClass (core.es5.js:10920)

在 app.module.ts

中添加了这些行

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';

@NgModule({
  imports: [    
    NgbModule
  ]
})

使用命令

安装了 ng-bootstrap

npm install --save @ng-bootstrap/ng-bootstrap

Answer 1

您应该导入 NgbModule.forRoot() 而不是 NgbModule。

The exact method will be slightly different for the root (top-level) module for which you should end up with the code similar to (notice NgbModule.forRoot()):
import {NgbModule} from '@ng-bootstrap/ng-bootstrap';

@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgbModule.forRoot(), ...],
  bootstrap: [AppComponent]
})
export class AppModule {
}
Other modules in your application can simply import NgbModule:
import {NgbModule} from '@ng-bootstrap/ng-bootstrap';

@NgModule({
  declarations: [OtherComponent, ...],
  imports: [NgbModule, ...]
})
export class OtherModule {
}

这是工具提示的工作示例：

请将您的代码与它进行比较。

将 NgbTooltipConfig 添加到提供程序

@NgModule({
  imports: [    
    NgbModule
  ],
  providers: [
     NgbTooltipConfig
  ]
})

并将此 css 添加到您的 style.css

.tooltip{
  opacity:1!important;
}
