Question

我正在努力将ng2-dragula绑定到AspNetCore SPA template。尝试了一切，但仍然得到：

Exception: Call to Node module failed with error: Error: Template parse errors:
Can't bind to 'dragula' since it isn't a known property of 'div'. ("
<div>
<div class='wrapper'>
<div class='container' [ERROR ->][dragula]='"first-bag"'>
<div>Drag/drop item 1</div>
</div>
"): ng:///AppModule/DragulaComponent.html@7:31
at syntaxError (C:\Users\...\ClientApp\dist\vendor.js:36125:34)

有没有人在AspDotnetCoreSpa中使用过ng2-dragula？

dragula.component.html

<div>
 <div class='wrapper'>
  <div class='container' [dragula]='"first-bag"'>
   <div>Drag/drop item 1</div>
  </div>
 </div>
</div>

dragula.component.ts

import { Component } from '@angular/core';
import { DragulaModule, DragulaService } from 'ng2-dragula'

@Component({
   selector: 'dragula',
   templateUrl: './dragula.component.html',
   styleUrls: ['../../../../node_modules/dragula/dist/dragula.min.css']
 })
 export class DragulaComponent {
}

app.module.client.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { DragulaModule } from 'ng2-dragula';
import { HttpModule } from '@angular/http';
import { sharedConfig } from './app.module.shared';

@NgModule({
    bootstrap: sharedConfig.bootstrap,
    declarations: sharedConfig.declarations,
    imports: [
        BrowserModule,
        FormsModule,
        DragulaModule,
        HttpModule,
        ...sharedConfig.imports
    ],
    providers: [
        { provide: 'ORIGIN_URL', useValue: location.origin }
    ]
})
export class AppModule {
}

app.module.shared.ts

import { NgModule } from '@angular/core';
import { RouterModule } from '@angular/router';

import { AppComponent } from './components/app/app.component'
import { NavMenuComponent } from './components/navmenu/navmenu.component';
import { HomeComponent } from './components/home/home.component';
import { FetchDataComponent } from './components/fetchdata/fetchdata.component';
import { CounterComponent } from './components/counter/counter.component';
import { DragulaComponent } from './components/dragula/dragula.component';

export const sharedConfig: NgModule = {
    bootstrap: [ AppComponent ],
    declarations: [
        AppComponent,
        NavMenuComponent,
        CounterComponent,
        FetchDataComponent,
        DragulaComponent,
        HomeComponent
    ],
    imports: [
        RouterModule.forRoot([
            { path: '', redirectTo: 'home', pathMatch: 'full' },
            { path: 'home', component: HomeComponent },
            { path: 'counter', component: CounterComponent },
            { path: 'fetch-data', component: FetchDataComponent },
            { path: 'dragula', component: DragulaComponent },
            { path: '**', redirectTo: 'home' }
        ])
    ]
};

Answer 1

尝试在您的app模块（顶级模块）中导入DragulaModule

Answer 2

我希望您使用的是模块基础结构（如下所示）：

Click : Project Structure

在这个应用程序中，有一些模块，如仪表板，拖拉机等。

在这种情况下，如果您想添加拖拽拖放（ng2-dragula），您需要做的是，在DragulaModule中添加app.module.ts import { DragulaModule } from '../../node_modules/ng2-dragula/ng2-dragula';

一旦你这样添加，如果你试图在[dragula]='"bag-something"'（html文件）中使用dragula.component.html，它仍然会给出错误Can't bind to 'dragula' since it isn't a known property of 'div'.

因此，解决方案是在模块的DragulaModule文件中添加xxx.module.ts。在这种情况下，您必须添加dragula模块的dragula.module.ts文件

注意：导入DragulaModule时，ng2-dragula/ng2-dragula的路径可能因项目结构而异。

Angular 4无法与'dragula＆＃39;因为它不是“div”的已知属性。
