我有一個（網格）組件巫婆多次使用。問題在於它很大，大約70％可以動態生成 - 我想，但有很多方法可以解決，這是最好的？angular 4減少html內容

正如你可以看到我只需要更改列名，搜索輸入的名稱，項目領域和DOM元素屬性（類，fxFlex） - 來響應。什麼是壓縮內容的最佳實踐（分離的組件，模板，指令），但保持容易使用？
（項目對象的數量字段不同）。
附加信息：
在ItemsComponent實現的基本方法，這樣一來，我可以覆蓋它們是必需的。
import { Component, OnInit, OnDestroy } from '@angular/core';
import { Router } from '@angular/router';
import {
FormGroup,
FormControl,
Validators,
FormBuilder,
FormArray
} from "@angular/forms";
import {
StorageService,
SystemService,
RequestService,
PopupService,
PaginatorService
} from '../_shared';
import {
ItemsComponent
} from '../_generals';
@Component({
selector: 'app-basic-characters',
templateUrl: './basic-characters.component.html',
styleUrls: ['./basic-characters.component.scss'],
providers: [PaginatorService]
})
export class BasicCharactersComponent extends ItemsComponent implements OnInit {
public item: string = "basicCharacters";
public class: string = 'BasicCharactersComponent';
constructor(
router: Router,
paginator: PaginatorService,
popup: PopupService,
storage: StorageService,
request: RequestService
) {
super(router, paginator, popup, storage, request);
}
public ngOnInit() {
super.ngOnInit();
// console.log('child init');
}
public newSearchForm(){
return new FormGroup({
'type': new FormControl(''),
'level': new FormControl(''),
'stats': new FormControl(''),
});
}
public newSimpleForm(){
return new FormGroup({
'simple': new FormControl('')
});
}
}
使它成爲一個組件，並使所有這些變量都是你剛剛命名的輸入。 – Ken
我不會失去功能的參考嗎？例如：onAdd（），onDelete（）？ – Twois
所有這些都應該在組件中定義。 – Ken
