问题描述
我正在使用Angular 2的ES5版本. 而且我遇到了这个错误:
I'm using ES5 flavor of Angular 2. And I've encountered this error:
Unhandled Promise rejection: Template parse errors:
More than one component matched on this element.
Make sure that only one component's selector can match a given element.
Conflicting components: class2,class6 ("
</tbody>
</table>
[ERROR ->]<paging [data]="data" (changed)="loadCountries($event)" unit="country"></paging>
<md-spinner class="lis"): class18@30:0 ; Zone: <root> ; Task: Promise.then ; Value:
它表示class2
和class6
.我找不到这些类的原始名称.
It says class2
and class6
. I can't find out the original names of the classes.
这是我的模块定义:
var module = ng.core.NgModule({
imports: [
ng.platformBrowser.BrowserModule,
ng.router.RouterModule.forRoot([].concat([...])),
ng.material.MaterialModule,
ng.http.HttpModule,
ng.common.CommonModule,
ng.forms.FormsModule],
declarations: [
app.CoalAddWorldCoalSupply,
app.FilterValuesDialog,
app.CoalFlows,
app.ImportWorldCoalSupplies,
app.CoalProducts,
app.CoalReports,
app.CoalUpsertFlow,
app.CoalUpsertProduct,
app.CoalWorldCoalSupplies,
app.CountryList,
app.CountryUpsert,
app.Dashboard,
app.ElectricityHeatGenerations,
...
],
entryComponents: [app.FilterValuesDialog, confirmDialog],
bootstrap: [app.Layout],
providers: [globalService]
})
.Class({
constructor: function () { }
});
document.addEventListener('DOMContentLoaded', function () {
ng.platformBrowserDynamic
.platformBrowserDynamic()
.bootstrapModule(module);
});
用...
指定的零件意味着更多相同的东西.
Parts specified with ...
means more of the same things.

推荐答案
假设我们有以下应用程序:
Let's say we have the following app:
app.component.js
app.AppComponent = Component({
selector: 'my-app',
template:
'<h1>(es5) angular2 4.1.3</h1><comp1></comp1>'
})
.Class({
constructor: function AppComponent() {}
});
component1.js
app.Component1 = Component({
selector: 'comp1',
template:
'component1'
})
.Class({
constructor: function Component1() {}
});
component2.js
app.Component2 = Component({
selector: 'comp1',
template:
'component2'
})
.Class({
constructor: function Component2() {}
});
