【问题描述】:
我一直在尝试使用 plunker http://plnkr.co/edit/?p=preview 实现 ng-bootstrap 下拉。
它不工作,我找不到问题
system.config.js 代码下方,
/**
* System configuration for Angular samples
* Adjust as necessary for your application needs.
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles
'@angular/core': 'npm:@angular/core/bundles/core.umd.js',
'@angular/common': 'npm:@angular/common/bundles/common.umd.js',
'@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
'@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
'@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
'@angular/http': 'npm:@angular/http/bundles/http.umd.js',
'@angular/router': 'npm:@angular/router/bundles/router.umd.js',
'@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
'@ng-bootstrap/ng-bootstrap': 'node_modules/@ng-bootstrap/ng-bootstrap/bundles/ng-bootstrap.js',
// other libraries
'rxjs': 'npm:rxjs',
'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js'
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
}
});
})(this);
app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { NgbdDropdownConfig } from 'app/dropdown-config';
import { AppComponent } from './app.component';
@NgModule({
imports: [ BrowserModule, ],
declarations: [ AppComponent,NgbdDropdownConfig ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
app.component.ts 代码
import { Component } from '@angular/core';
import { NgbModule } from '@ng-bootstrap/ng-bootstrap';
import { NgbdDropdownConfig } from 'app/dropdown-config';
@Component({
selector: 'my-app',
template: ` <div class="container-fluid">
<ngbd-dropdown-config></ngbd-dropdown-config>
</div>`,
})
export class AppComponent { }
dropdown-config.ts 代码
import {Component} from '@angular/core';
import {NgbDropdownConfig} from '@ng-bootstrap/ng-bootstrap';
@Component({
selector: 'ngbd-dropdown-config',
templateUrl: 'app/dropdown-config.html',
providers: [NgbDropdownConfig] // add NgbDropdownConfig to the component providers
})
export class NgbdDropdownConfig {
constructor(config: NgbDropdownConfig) {
// customize default values of dropdowns used by this component tree
config.up = true;
config.autoClose = false;
}
}
下拉配置.html
<p>This dropdown uses customized default values.</p>
<div ngbDropdown>
<button class="btn btn-outline-primary" id="dropdownMenu3" ngbDropdownToggle>Toggle</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenu3">
<button class="dropdown-item">Action - 1</button>
<button class="dropdown-item">Another Action</button>
<button class="dropdown-item">Something else is here</button>
</div>
</div>
由于没有错误信息,我无法找到问题。任何人都可以找出问题所在。谢谢。
【问题讨论】:
-
请正确链接到 plunker
-
究竟是什么问题?
-
对不起,这是链接,在最后一个中,我实现了“下拉菜单的全局配置”ng-bootstrap.github.io/#/components/dropdown
-
切换的下拉不能同时工作,它没有显示任何错误。
-
您提供了工作示例的链接!要解决您的问题,我们应该从遇到此问题的 plunker 开始。比先做工作重现你的问题然后解决它更有效
