【问题描述】:
我有一个 6 列的垫子表。在第 5 列中,它显示作业的状态,即已完成、正在运行或待处理。 我创建了两个按钮,即停止和重新运行。 我想编写功能,如果作业完成,则应禁用停止按钮并应启用重新运行,这意味着用户应该能够重新运行已完成的作业以及作业是否正在执行或挂起(等待执行)然后应该启用停止按钮并禁用重新运行,这意味着用户应该能够停止正在运行的作业。 有人可以帮我吗?
我创建了一个示例stackblitz here.
HTML 代码:
<div class="main-content">

<button
mat-icon-button
(click)="stop_exec_job()"
matTooltip="Stop Executing the Job"
>
<!-- Edit icon for row -->
<i class="material-icons" style="color:red"> stop </i>
</button>
</mat-toolbar>
<div class="card">
<div class="card-header">
<h5 class="title">Job Execution Stats</h5>

<mat-table [dataSource]="jobExecutionStat">

出于某种原因,停止和缓存是图标,在我的视觉工作室中我可以看到图标,但在 stackblitz 中我无法将它们转换为图标。 仅供参考,红色停止是停止,绿色缓存是重新运行
【问题讨论】:
-
您的问题到底是什么?图标不显示或按钮不工作或状态不持久?
-
按钮不起作用。我创建了一个函数 stop_exec_job 但我不知道如何编写一个函数,如果状态为 Completed 则应启用重新运行按钮。不显示图标是为了让 SOF 用户在查看 stackblitz 时不要感到困惑
