我有一些任务表，在那个表中每一行都有一个任务。 在每一行中都有一个状态，它是一个按钮的 Controller 。每个任务的初始状态将显示为进行中，按钮的文本显示为标记完成，但是当单击按钮时，任务的状态将更改为< strong>Done 并将按钮的文本更改为 Mark In Progress。如果将来如果我们想更改“完成”任务的状态，那么我们可以通过“标记进行中”按钮更改状态。
在这个现场演示中，

最佳答案
尝试使用 ng-show 和 ng-hide 指令。
这是 Plunkr .
例如
<table class="table table-striped">
<tbody>
<tr>
<td style="width: 1px;"></td>
<td>
<b>Task</b>
</td>
<td>
<b>Options</b>
</td>
</tr>
<tr ng-repeat="task in tasks">
<td>
<span ng-show="done" class="label label-success">Done</span>
<span ng-hide="done" class="label label-important">In Progress</span>
</td>
<td>{{task.title}}</td>
<td>{{task.description}}</td>
<td>
<a class="btn" data-toggle="modal" data-target="#modal" ng-click="editTask(task)">Edit</a>
</td>
<td>
<a class="btn" data-toggle="modal" data-ng-click="removeRow(task)">Delete</a>
</td>
<td ng-show="done">
<span>
<button ng-click="done = !done" class="btn">Mark In Progress</button>
</span>
</td>
<td ng-hide="done">
<span>
<button ng-click="done = !done" class="btn">Mark Done</button>
</span>
</td>
</tr>
</tbody>
