在< tr>中嵌入角度指令 [英] Embedding an Angular Directive in <tr>

问题描述

我正在尝试获取在<tr>内部重复的角度指令.如果没有该指令，则代码为

I'm trying to get an angular directive to repeat inside a <tr>. Without the directive, the code is

<tr *ngFor='let cluster of clusters'>
    <td style='display: flex; flex-direction: column; width: 40%; min-width: 300px;'>
        <span>{{ cluster.Name }}</span>
        <span>{{ cluster.StatusMessage }}</span>
    </td>
    <td style='width: 100%;'>
        ...
    </td>
</tr>

看起来像

重构指令时，我丢失了<tr>格式.重构后的代码是

When I refactor the directive, I lose the <tr> formatting. The refactored code is

<tr *ngFor='let cluster of clusters'>
    <cluster-row [name]='cluster.Name' [statusMessage]='cluster.StatusMessage'></cluster-row>
</tr>

集群行组件代码为:

<td style='display: flex; flex-direction: column; width: 40%; min-width: 300px;'>
    <span>{{ name }}</span>
    <span>{{ statusMessage }}</span>
</td>
<td style='width: 100%;'>
    ...
</td>

它可以工作，但是<tr>格式消失了.

It works, but the <tr> formatting goes away.

开发人员工具显示了一个<tr>和一个嵌套的<cluster-row>嵌套的<tr>，正如我期望的那样.

The developer tools show a <tr> with a <cluster-row> nested in it, and two <td>s nested in that, as I would expect.

推荐答案

<tr>不能包含<cluster-row>元素.

您可以改为使用属性选择器，例如

You can use an attribute selector instead like

<tr *ngFor='let cluster of clusters'>
    <td cluster-row [name]='cluster.Name' [statusMessage]='cluster.StatusMessage'></cluster-row>
</tr>

使用

@Component({
//@Directive({
  selector: '[cluster-row]'

该组件或指令是<td> ，因此您不能在组件模板中重复它

The component or directive then is the <td>, therefore you can't repeat it inside the components template

style='display: flex; flex-direction: column; width: 40%; min-width: 300px;'

可以直接添加到

@Component({ 
  selector: '[cluster-row]',
  styles: [...],
