如何在表格行中显示对象数组

Question

下面是员工详细信息数组，其中包含对象我想在表格行中显示员工详细信息：

this.employeedetails = [
{ id: 1, firstname: 'AM', lastname:'CM', age:3 },
  { id: 1, firstname: 'AM', lastname: 'DIM', age:4 },
  { id: 1, firstname: 'AM', lastname: 'FM', age:5 },
  { id: 1, firstname: 'AM', lastname: 'HM', age:6 }, ];

这就是我试图在 html 文件中打印我的数组的方式

{{员工详情}}

Answer 1

更正您的变量名称，例如：

this.employeeDetails = [
{ id: 1, firstName: 'AM', lastName:'CM', age:3 },
  { id: 1, firstName: 'AM', lastName: 'DIM', age:4 },
  { id: 1, firstName: 'AM', lastName: 'FM', age:5 },
  { id: 1, firstName: 'AM', lastName: 'HM', age:6 } ];

那么对于表：

<table >
      <thead>
        <tr>
          <th scope="col">Id</th>
          <th scope="col">First Name</th>
          <th scope="col">Last Name</th>
          <th scope="col">Age</th>      
        </tr>
      </thead>
      <tbody>
        <tr *ngFor="let employee of employeeDetails ">
          <th scope="row">{{ employee.id}}</th>
          <td>{{ employee.firstName}}</td>
          <td>{{ employee.lastName}}</td>
          <td>{{ employee.age}}</td>
        </tr>
      </tbody>
    </table>

Answer 2

首先你的json应该是无效的

employeeDetails = [
{ id: 1, firstName: 'AM', lastName:'CM', age:3 },
  { id: 1, firstName: 'AM', lastName: 'DIM', age:4 },
  { id: 1, firstName: 'AM', lastName: 'FM', age:5 },
  { id: 1, firstName: 'AM', lastName: 'HM', age:6 }, ];

然后用户*ngFor在html中喜欢

<table>
<tr>
<td>First name</td>
<td>Last name</td>
</tr>
<tr *ngFor="let item of employeeDetails">
<td>{{item.firstName}}</td>
<td>{{item.lastName}}</td>
</tr></table>

Answer 3

首先去掉数组名之间的空格 它可以是employee_details 你可以这样做

<table>
 <thead>
    <tr> 
      <th> First Name </th>
      <th> Lats Name </th>
      <th> Age </th>
    </tr> 
 </thead>
 <tbody> 
   <tr *ngFor= let array of employee_details> 
       <td> {{array.first}} </td>
       <td> {{array.last_name}} </td>
       <td> {{array.age}} </td>
   </tr>
 </tbody>
</table>
