我想知道如何使用DirectiveResolver
对象来改变给定的Component
。
依赖关系(如今,ng2移动如此之快,事情很快就会过时)
"@angular/common": "~2.4.3",
"@angular/compiler": "~2.4.3",
"@angular/core": "~2.4.3",
我试过这个:
import { Component } from '@wwwalkerrun/nativescript-ngx-magic';
import { OnInit, Directive, Type } from '@angular/core';
import { DirectiveResolver } from '@angular/compiler';
class myViewResolver extends DirectiveResolver {
resolve(type: Type<any>, throwIfNotFound?: boolean): Directive {
var view = super.resolve(type, throwIfNotFound);
console.log(type);
console.log(view);
return view;
}
}
@Component({
selector: 'app-root',
templateUrl: 'views/app/app.component.html',
styleUrls: ['views/app/app.component.css'],
providers: [myViewResolver]
})
export class AppComponent {
title = 'app works!';
}
但是我没有得到日志所以我怀疑解析器没有被执行。
有什么想法吗?
ps:官方angular.io api文档中没有条目...
答案 0 :(得分:3)
您需要通过bootstrapping应用程序传递额外的提供程序来覆盖默认的编译器提供程序。
所以我认为这应该有效:
platformBrowserDynamic().bootstrapModule(AppModule, {
providers: [
{ provide: DirectiveResolver, useClass: myViewResolver }
]
});
