angular2 中带有嵌套组件的 Bootstrap 表 [英] Bootstrap table with nested components in angular2

问题描述

我是 angular2 的初学者，我尝试使用嵌套组件构建引导表，子组件显示在单个单元格中.可能我在 ngFor 循环上做错了什么.这是我的子组件:

import { Component, OnInit, ViewEncapsulation, Input } from '@angular/core';从'../customer'导入{客户}；从'../customers.component'导入{客户组件}@成分({选择器:'单一客户'，封装:ViewEncapsulation.None，输入:['客户']，templateUrl: './single-customer.component.html',styleUrls: ['./single-customer.component.css']})导出类 SingleCustomerComponent 实现 OnInit {客户:客户；构造函数(){}ngOnInit() {}}

和模板:

{{客户.姓氏 |大写}}</td><td>{{顾客姓名}}</td><td>{{客户.电话}}</td><td>{{customer.mail}}</td><td>{{customer.comments}}</td><td><button type="button" class="btn btn-primary btn-xs" data-toggle="modal" data-target=".update-customer-modal" ng-click="setCustomerData(customer)">Edytuj</button></td><td><button type="button" class="btn btn-danger btn-xs" data-toggle="modal" data-target=".delete-customer-modal" ng-click="setCustomerData(customer)">Usuń</button></td><!-- </tr>-->

父组件:

import { Component, OnInit, Directive, ViewEncapsulation } from '@angular/core';从 '@angular/common' 导入 { NgFor };import { SingleCustomerComponent } from './single-customer/single-customer.component';从'./customer'导入{客户}；从'./customers.service'导入{客户服务}；@成分({选择器:'应用程序客户'，封装:ViewEncapsulation.None，templateUrl: './customers.component.html',styleUrls: ['./customers.component.css'],提供者:[CustomersService]，})导出类 CustomersComponent 实现 OnInit {客户:客户[]；客户长度:数量；构造函数(私有_customersService:CustomersService){}ngOnInit() {this.getCustomers();}获取客户(){this._customersService.getCustomers().then((res) => {this.customers = res;this.customersLength = this.customers.length;});}}

父模板:

<div class="table-responsive"><table class="table table-hover"><头><tr class="信息"><td>ID</td><td>纳兹维斯科</td><td>IMIĘ</td><td>TELEFON</td><td>邮件</td><td>URODZINY</td><td>UWAGI</td><td></td><td></td></tr></thead><tr *ngFor="让客户的客户"><single-customer [customer]="customer"></single-customer></tr></tbody>

和父母模块:

import { NgModule } from '@angular/core';从'@angular/common'导入{CommonModule}；从'./customers.component'导入{CustomersComponent}；import { SingleCustomerComponent } from './single-customer/single-customer.component'@NgModule({进口:[通用模块，],声明:[CustomersComponent, SingleCustomerComponent]})导出类客户模块 { }

我做错了什么?

解决方案

HTML 中的表格元素只允许 thead、tbody、tfoot 和tr 作为孩子.

您可以将子组件的选择器更改为:

@Component({选择器:'[单一客户]'，...})导出类 SingleCustomerComponent 实现 OnInit {...

并将您的父模板更改为:

<预><代码>...<tr *ngFor="让客户的客户"单一客户[客户]="客户"></tr></tbody>...

I'm the begginer with angular2, and i try to build bootstrap table with nested components, the child component is display in single cell. Probably I'm doing something wrong with ngFor loop. This is my child component:

import { Component, OnInit, ViewEncapsulation, Input } from '@angular/core';
import { Customer } from '../customer';
import { CustomersComponent } from '../customers.component'

@Component({
  selector: 'single-customer',
  encapsulation: ViewEncapsulation.None,
  inputs:['customer'],
  templateUrl: './single-customer.component.html',
  styleUrls: ['./single-customer.component.css']
})
export class SingleCustomerComponent implements OnInit {
    customer: Customer;

  constructor() { }

  ngOnInit() {
  }
}

and template:

<td>
        {{customer.surname | uppercase}}
    </td>
    <td>
        {{customer.name}}
    </td>
    <td>
        {{customer.phone}}
    </td>
    <td>
        {{customer.mail}}
    </td>
    <td>
        {{customer.comments}}
    </td>
    <td><button type="button" class="btn btn-primary btn-xs" data-toggle="modal" data-target=".update-customer-modal" ng-click="setCustomerData(customer)">Edytuj</button></td>
    <td><button type="button" class="btn btn-danger btn-xs" data-toggle="modal" data-target=".delete-customer-modal" ng-click="setCustomerData(customer)">Usuń</button></td>
<!-- </tr> -->

Parent component:

import { Component, OnInit, Directive, ViewEncapsulation } from '@angular/core';
import { NgFor } from '@angular/common';
import { SingleCustomerComponent } from './single-customer/single-customer.component';
import { Customer } from './customer';
import { CustomersService } from './customers.service';

@Component({
  selector: 'app-customers',
  encapsulation: ViewEncapsulation.None,
  templateUrl: './customers.component.html',
  styleUrls: ['./customers.component.css'],
  providers: [CustomersService], 
})

export class CustomersComponent implements OnInit {

    customers: Customer[];
    customersLength: number;

    constructor(private _customersService: CustomersService) {
     }

    ngOnInit() {
        this.getCustomers();
    }

    getCustomers(){
        this._customersService.getCustomers().then((res) => {
            this.customers = res;
            this.customersLength = this.customers.length;
    });
}
}

parent template:

<div class="col-md-12">
            <div class="table-responsive">
                <table class="table table-hover">
                    <thead>
                        <tr class="info">
                            <td>ID</td>
                            <td>NAZWISKO</td>
                            <td>IMIĘ</td>
                            <td>TELEFON</td>
                            <td>MAIL</td>
                            <td>URODZINY</td>
                            <td>UWAGI</td>
                            <td></td>
                            <td></td>
                        </tr>
                    </thead>
                    <tbody>
                        <tr *ngFor="let customer of customers">
                       <single-customer [customer]="customer"></single-customer>
                        </tr>

                    </tbody>
                </table>
            </div>
        </div>

and parents module:

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { CustomersComponent } from './customers.component';
import { SingleCustomerComponent } from './single-customer/single-customer.component'

@NgModule({
  imports: [
    CommonModule,
  ],
  declarations: [CustomersComponent, SingleCustomerComponent]
})
export class CustomersModule { }

What I'm doing wrong?

解决方案

Table element in HTML just allows thead, tbody, tfoot and tr as children.

You can change your children component's selector to:

@Component({
    selector: '[single-customer]',
    ...
})
export class SingleCustomerComponent implements OnInit {
    ...

And change your parent template to:

...    
<tbody>
    <tr *ngFor="let customer of customers"
        single-customer
        [customer]="customer">
    </tr>
</tbody>
...
