Angular 4: Table 动态数据
Angular 4: Table with dynamic data
我正在尝试使用 angular 4 创建一个动态 table,但不允许我将 *ngFor 与 tr 一起使用?知道如何解决这个问题吗?
<table class="table table-bordered table-sm m-0">
<thead class="">
<tr>
<th>FirstName</th>
<th>Name</th>
<th>Registration Date</th>
<th>Phone</th>
<th>E-mail address</th>
<th>Role</th>
</tr>
</thead>
<tbody >
<tr *ngFor="user in users">
<td>{{user.firstName}}</td>
<td>{{user.lastName}}</td>
<td>{{user.registrationDate}}</td>
<td>{{user.phoneNumber}}</td>
<td>{{user.email}}</td>
<td>{{user.userRole}}</td>
</tr>
</tbody>
</table>
准确的错误是:
compiler.es5.js:1690 Uncaught Error: Template parse errors: Can't bind
to 'ngFor' since it isn't a known property of 'tr'. ("
]*ngFor="user in users">
{{user.firstName}}
{{user.lastName}} "): ng:///AppModule/UserListComponent.html@15:10 Can't bind to 'ngForIn'
since it isn't a known property of 'tr'. ("
你 ngFor
是错误的,因为 ngForIn
已被弃用 (refer docs)
<tr *ngFor="let user of users">
<td>{{user.first_name}}</td>
<td>{{user.last_name}}</td>
</tr>
在angular的新语法中,您需要为结构指令声明局部变量。
所以使用,
<tr *ngFor="let user of users">
<td>{{user.firstName}}</td>
<td>{{user.lastName}}</td>
<td>{{user.registrationDate}}</td>
<td>{{user.phoneNumber}}</td>
<td>{{user.email}}</td>
<td>{{user.userRole}}</td>
</tr>
let 关键字声明您在模板中引用的模板输入变量。
