在Oracle数据库中,存在这样的参数“活动” ,其数据类型为“ VARCHAR2(1字节)” 。此处使用 Y 和 N 的值。 如果要启用 Y ,我要使复选框处于活动状态,而 N 则不处于活动状态。
我想这样做,但是到处都是复选框:
<table class="table table-hover">
<thead>
<tr>
<th [class.active]="key === 'name'" (click)="setOrder('name')"><b>Name <span [hidden]="reverse">▼</span><span [hidden]="!reverse">▲</span></b></th>
<th style="text-align: center;" [class.active]="key === 'active'" (click)="setOrder('active')"><b>File <span [hidden]="reverse">▼</span><span [hidden]="!reverse">▲</span> </b></th>
</tr>
</thead>
<tbody>
<tr *ngFor="let project of projects | orderBy: key:reverse | let projectIndex = index" >
<td >{{project.name}}</td>
<td style="text-align: center">
<input type="checkbox" [checked]="project.active == 'Y'" class="material_checkbox" [(ngModel)]="project.active" name="active_{{projectIndex}}" disabled />
</td>
</tr>
</tbody>
</table>
如何设置条件,以便如果存在 Y ,则复选框处于活动状态,而如果 N ,则处于非活动状态?>

我检查了一下,因为您的[ngModel]不是布尔值,所以应该将其删除。只需使用以下解决方案即可:-
[[ClassName.methodName]]

我认为这是您的基本项目类型:
interface Project {
name: string,
active: string;
// additional properties.
}
如果是,则:
projectList: Project[];
constructor() {
this.populateProjectList();
}
populateProjectList(): void {
this.projectList = [];
this.projectList.push({name: 'project1', active: 'Y'});
this.projectList.push({name: 'project2', active: 'N'});
this.projectList.push({name: 'project3', active: 'Y'});
this.projectList.push({name: 'project4', active: 'N'});
}
// In your HTML
<p *ngFor="let project of projectList">
<label for="">{{project.name}}</label>
<input type="checkbox" [checked]="project.active == 'Y'">
</p>
