未找到组件工厂。你把它添加到@NgModule.entryComponents了吗?
No component factory found. Did you add it to @NgModule.entryComponents?
在将 ag-grid 与 angular4 一起使用时,我遇到了以下错误消息。
我试图在通过 HTTP json 获取后显示行数据。
this.gridOptions.api.setRowData(this.gridOptions.rowData);
但是我的代码出现了以下错误信息。
ERROR Error: No component factory found for RedComponentComponent. Did
you add it to @NgModule.entryComponents?
这是我的应用模块代码。我已经设置为 entryComponents.
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AgGridModule} from "ag-grid-angular/main";
import { AppComponent } from './app.component';
import { MyGridApplicationComponent } from './my-grid-application/my-grid-application.component';
import { RedComponentComponent } from './red-component/red-component.component';
@NgModule({
imports: [
BrowserModule,
AgGridModule.withComponents(
[RedComponentComponent]
),
FormsModule,
HttpModule
],
declarations: [
AppComponent,
MyGridApplicationComponent,
RedComponentComponent
],
entryComponents: [
RedComponentComponent
],
providers: [],
bootstrap: [AppComponent]
})

我的问题。为什么此代码无法解析此组件。
从服务器加载数据时,您正在将 string
传递给 `ComponentFactoryResolver,但它应该是组件类型。
header.json
{
"headerName": "DetailCode",
"field": "detailCode",
"cellRendererFramework": "RedComponentComponent", // string
"width":100
},
为了解决这个问题,我会创建入口组件映射,例如:
条目-components.ts
import { RedComponentComponent } from './red-component/red-component.component';
export const entryComponentsMap = {
'RedComponentComponent': RedComponentComponent
};
然后从 json 字符串映射加载到组件 class
comm-code-grid-option.service.ts
private fetchColumnDefs() {
console.log("fetchColumnDefs()");
this.http.get(this.API_URI + "resident/header.json").subscribe(
r => {
this.gridOptions.columnDefs = r.json();
this.gridOptions.columnDefs.forEach((x: any) => {
if (x.cellRendererFramework) {
x.cellRendererFramework = entryComponentsMap[x.cellRendererFramework];
}
});
