Answer 1

您可以这样写：

<div ng-repeat="todo in todos">
    <input type="text" ng-model="todo.title" ng-readonly=!todo.editorEnabled" />
    <button ng-click="todo.editorEnabled = true">Disable me</button>
</div>

更新

您的HTML代码对您的问题是隐藏的，因为您没有正确格式化它。我为您提供一个基本示例：

<li href="#" class="list-group-item clearfix" ng-repeat="todo in todos">
    <div class="col-md-10">
        <div class="input-group">
            <span class="input-group-addon" id="basic-addon1">
                <input type="checkbox" ng-model="todo.done">
            </span>
            <input type="text" class="form-control" aria-describedby="basic-addon1"
                   ng-model="todo.title" ng-readonly="todo.disableEditor"/>
        </div>
    </div>
    <div class="text-right col-md-2">
        <label ng-click="todo.disableEditor = true" class="btn btn-info">Edit</label>
        <label ng-show="!todo.disableEditor">
            <label ng-click="save()" class="btn btn-success">Save</label>
            <label ng-click="disableEditor()" class="btn btn-warning">cancel</label>
        </label>
        <label class="btn btn-danger" ng-click="delete($index)">Delete</label>
    </div>
</li>

您修改后的plunkr：https://jsfiddle.net/oynrxkgv/搜索todo.edit的使用情况，您会看到那里发生了什么。

Answer 2

现在我得到了你的确切问题，

编辑按钮：

<label ng-click="first($index); editText=false;editorEnabled='true'" class="btn btn-info" ng-hide="editorEnabled" >Edit</label>

文本框：

<input type="text" class="form-control" aria-describedby="basic-addon1" ng-model="todo.title" ng-disabled="editText" />

对JS文件中的标志也进行了必要的更改。看看这把小提琴。我想这就是你想做的：
