javascript - 将 html 表转换为 mat 表( Angular )

Question

我当前有一个 HTML 表，它是使用 for 循环从本地存储中逐行填充的。我想知道是否有人能够帮助我将其作为 Angular Material 表工作。我已经尝试了人们在论坛上推荐的所有建议和代码，但没有成功。

在我的示例中，该组件唯一使用的页面是添加和列表组件。

Here is a link to my stackblitz project.

Answer 1

我假设您已经在项目中安装了 Angular Material 。

第 1 步:- 为您的数据创建接口(interface)。

export interface PeriodicElement {
  name: string;
  position: number;
  weight: number;
  symbol: string;
}

第 2 步:- 然后在您的组件中您必须添加此内容。

displayedColumns: string[] = ['position', 'name', 'weight', 'symbol'];
dataSource: PeriodicElement[] = [];

displayedColumns 表示列名称。 步骤 3:- 然后在 oninit 方法中，您可以将数据分配给 dataSource 变量。

this.dataSource = [
    {position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H'},
    {position: 2, name: 'Helium', weight: 4.0026, symbol: 'He'},
    {position: 3, name: 'Lithium', weight: 6.941, symbol: 'Li'},
    {position: 4, name: 'Beryllium', weight: 9.0122, symbol: 'Be'},
    {position: 5, name: 'Boron', weight: 10.811, symbol: 'B'},
    {position: 6, name: 'Carbon', weight: 12.0107, symbol: 'C'},
    {position: 7, name: 'Nitrogen', weight: 14.0067, symbol: 'N'},
    {position: 8, name: 'Oxygen', weight: 15.9994, symbol: 'O'},
    {position: 9, name: 'Fluorine', weight: 18.9984, symbol: 'F'},
    {position: 10, name: 'Neon', weight: 20.1797, symbol: 'Ne'},
];

stpe 4 :- 在 html 中你可以这样显示它。

<table mat-table [dataSource]="dataSource" class="mat-elevation-z8">

  <!--- Note that these columns can be defined in any order.
        The actual rendered columns are set as a property on the row definition" -->

  <!-- Position Column -->
  <ng-container matColumnDef="position">
    <th mat-header-cell *matHeaderCellDef> No. </th>
    <td mat-cell *matCellDef="let element"> {{element.position}} </td>
  </ng-container>

  <!-- Name Column -->
  <ng-container matColumnDef="name">
    <th mat-header-cell *matHeaderCellDef> Name </th>
    <td mat-cell *matCellDef="let element"> {{element.name}} </td>
  </ng-container>

  <!-- Weight Column -->
  <ng-container matColumnDef="weight">
    <th mat-header-cell *matHeaderCellDef> Weight </th>
    <td mat-cell *matCellDef="let element"> {{element.weight}} </td>
  </ng-container>

  <!-- Symbol Column -->
  <ng-container matColumnDef="symbol">
    <th mat-header-cell *matHeaderCellDef> Symbol </th>
    <td mat-cell *matCellDef="let element"> {{element.symbol}} </td>
  </ng-container>

  <tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
  <tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
</table>

如果您仍有疑问，请告诉我。

更新代码

在list.component.ts中

添加这两个变量。

displayedColumns: string[] = ['ID', 'Product Name', 'Manufacturer', 'Audit Interval', 'Action Buttons'];
dataSource = [];

然后在 ngOnInit 中添加这个。

this.dataSource = this.people;

然后在list.component.html

<table mat-table [dataSource]="dataSource" class="mat-elevation-z8">

  <!--- Note that these columns can be defined in any order.
        The actual rendered columns are set as a property on the row definition" -->

  <!-- ID Column -->
  <ng-container matColumnDef="ID">
    <th mat-header-cell *matHeaderCellDef> ID </th>
    <td mat-cell *matCellDef="let element"> 1 </td>
  </ng-container>

  <!-- Product Name Column -->
  <ng-container matColumnDef="Product Name">
    <th mat-header-cell *matHeaderCellDef> Product Name </th>
    <td mat-cell *matCellDef="let element"> {{element.fName}} </td>
  </ng-container>

  <!-- Manufacturer Column -->
  <ng-container matColumnDef="Manufacturer">
    <th mat-header-cell *matHeaderCellDef> Manufacturer </th>
    <td mat-cell *matCellDef="let element"> {{element.lName}} </td>
  </ng-container>

  <!-- Audit Interval Column-->
  <ng-container matColumnDef="Audit Interval">
    <th mat-header-cell *matHeaderCellDef> Audit Interval </th>
    <td mat-cell *matCellDef="let element"> {{element.aDays}} </td>
  </ng-container>

  <!-- Action Column-->
  <ng-container matColumnDef="Action Buttons">
    <th mat-header-cell *matHeaderCellDef> Action Buttons </th>
    <td mat-cell *matCellDef="let element">
      <button mat-button mat-raised-button color="accent" [routerLink]="['/edit', i]">edit  </button> 
     <button mat-button mat-raised-button color="warn"  (click) = openDialog(i) > delete  </button>
    </td>
  </ng-container>

  <tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
  <tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
</table>

代码更新后，我可以渲染表格，请检查随附的屏幕截图。

目前您的数据中没有ID，您可以使用当前索引作为ID。 希望这会有所帮助。
