问题描述
目前，我有以下代码来填充表格.
Currently I have the following code to populate a table.
在component.ts中:
import { HttpClient } from "@angular/common/http";
import { Component, OnInit } from "@angular/core";
import { FormBuilder, FormGroup, Validators } from "@angular/forms";
import { ActivatedRoute, Router } from "@angular/router";
import { MatTableDataSource } from "@angular/material/table";
@Component({
styleUrls: ["./styles.scss"],
templateUrl: "./template.html"
})
export class MyRouteData {
employeeInfoTable: object;
constructor(private http: HttpClient) {}
ngOnInit() {
this.http
.get("http://localhost:5000/MyRoute/GetEmployeeInfo")
.subscribe(response => {
this.employeeInfoTable = response;
});
}
}
我的template.html文件如下:
<mat-card style="height: 98%">
<div style="height: 95%; overflow: auto;">
<table class="MyNiceStyle">
<thead>
<tr>
<td>Name</td>
<td>Age</td>
<td>Date Of Birth</td>
<td>Address</td>
<td>Postcode</td>
<td>Gender</td>
<td>Salary</td>
<td>Job Title</td>
</tr>
</thead>
<tr *ngFor="let data of employeeInfoTable">
<td>{{data.Name}}</td>
<td>{{data.Age}}</td>
<td>{{data.DateOfBirth}}</td>
<td>{{data.Address}}</td>
<td>{{data.Postcode}}</td>
<td>{{data.Gender}}</td>
<td>{{data.Salary}}</td>
<td>{{data.JobTitle}}</td>
</table>
</div>
</mat-card>
可以工作，但说实话，它看起来很糟糕.我想做的就是使用垫子表格: https://material.angular.io/components/table/examples
which works but honestly, it looks terrible. What I would like to do is to usea mat-table: https://material.angular.io/components/table/examples
我已将template.html更新为:
I've updated the template.html to:
<mat-card style="height: 98%">
<table mat-table [dataSource]="employeeInfoTable" class="mat-elevation-z8">
<ng-container matColumnDef="Name">
<th mat-header-cell *matHeaderCellDef>Name </th>
<td mat-cell *matCellDef="let element"> {{element.Name}} </td>
</ng-container>
<ng-container matColumnDef="DateOfBirth">
<th mat-header-cell *matHeaderCellDef> DateOfBirth </th>
<td mat-cell *matCellDef="let element"> {{element.DateOfBirth}} </td>
</ng-container>
<ng-container matColumnDef="Address">
<th mat-header-cell *matHeaderCellDef> Address </th>
<td mat-cell *matCellDef="let element"> {{element.Address}} </td>
</ng-container>
<ng-container matColumnDef="Postcode">
<th mat-header-cell *matHeaderCellDef> Postcode </th>
<td mat-cell *matCellDef="let element"> {{element.Postcode}} </td>
<ng-container matColumnDef="Gender">
<th mat-header-cell *matHeaderCellDef> Gender </th>
<td mat-cell *matCellDef="let element"> {{element.Gender}} </td>
</ng-container>
<ng-container matColumnDef="Salary">
<th mat-header-cell *matHeaderCellDef> Salary </th>
<td mat-cell *matCellDef="let element"> {{element.Salary}} </td>
</ng-container>
<ng-container matColumnDef="JobTitle">
<th mat-header-cell *matHeaderCellDef> JobTitle </th>
<td mat-cell *matCellDef="let element"> {{element.JobTitle}} </td>
</ng-container>
<tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
<tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
</table>
</mat-card>
当我运行它时，我只看到一个空白屏幕.没有控制台错误或类似的东西.我需要对template.html和/或component.ts进行哪些更改才能显示数据?
and when I run this I just see a blank screen. There are no console errors or anything like that. What changes do I need to make to template.html and/or component.ts to get the data to show?
推荐答案
您需要进行这些更改.
在component.ts中:
In component.ts:
import { HttpClient } from "@angular/common/http";
import { Component, OnInit } from "@angular/core";
import { FormBuilder, FormGroup, Validators } from "@angular/forms";
import { ActivatedRoute, Router } from "@angular/router";
import { MatTableDataSource } from "@angular/material";
import { Object} from "../object.model";
@Component({
styleUrls: ["./styles.scss"],
templateUrl: "./template.html"
})
export class MyRouteData implements OnInit {
employeeInfoTable : Object[] = [];
employeeInfoTableDataSource = new MatTableDataSource(this.employeeInfoTable);
displayedColumns: string[] = [
"Name",
"DateOfBirth",
"Address",
"Postcode",
"Gender",
"Salary"
"JobTitle"
];
constructor(private http: HttpClient) {}
ngOnInit() {
this.http.get("http://localhost:5000/MyRoute/GetEmployeeInfo")
.subscribe(response => {
this.employeeInfoTable = response;
this.employeeInfoTableDataSource.data = this.employeeInfoTable;
});
}
}
在object.model.ts
In object.model.ts
export interface Object{
id: number;
Name: string;
DateOfBirth: Date;
Address: string;
Postcode: string;
Gender: string;
Salary : number;
JobTitle : string;
}
在您的.html
<mat-card style="height: 98%">
<table mat-table [dataSource]="employeeInfoTableDataSource" class="mat-elevation-z8">
<ng-container matColumnDef="Name">
<th mat-header-cell *matHeaderCellDef>Name </th>
<td mat-cell *matCellDef="let element"> {{element.Name}} </td>
</ng-container>
<ng-container matColumnDef="DateOfBirth">
<th mat-header-cell *matHeaderCellDef> DateOfBirth </th>
<td mat-cell *matCellDef="let element"> {{element.DateOfBirth}} </td>
</ng-container>
<ng-container matColumnDef="Address">
<th mat-header-cell *matHeaderCellDef> Address </th>
<td mat-cell *matCellDef="let element"> {{element.Address}} </td>
</ng-container>
<ng-container matColumnDef="Postcode">
<th mat-header-cell *matHeaderCellDef> Postcode </th>
<td mat-cell *matCellDef="let element"> {{element.Postcode}} </td>
<ng-container matColumnDef="Gender">
<th mat-header-cell *matHeaderCellDef> Gender </th>
<td mat-cell *matCellDef="let element"> {{element.Gender}} </td>
</ng-container>
<ng-container matColumnDef="Salary">
<th mat-header-cell *matHeaderCellDef> Salary </th>
<td mat-cell *matCellDef="let element"> {{element.Salary}} </td>
</ng-container>
<ng-container matColumnDef="JobTitle">
<th mat-header-cell *matHeaderCellDef> JobTitle </th>
<td mat-cell *matCellDef="let element"> {{element.JobTitle}} </td>
</ng-container>
<tr mat-header-row *matHeaderRowDef="displayedColumns"></tr>
<tr mat-row *matRowDef="let row; columns: displayedColumns;"></tr>
</table>
</mat-card>
