使用ng-repeat时，能够编辑内容的最佳方式是什么？
在我的理想情况下，添加的生日将是一个超链接，当点击它时，它将显示一个编辑表单-就像当前带有更新按钮的添加表单一样。

您应该将表单放在每个节点中，并使用ng-show和ng-hide分别启用和禁用编辑。如下所示：
<li>
<span ng-hide="editing" ng-click="editing = true">{{bday.name}} | {{bday.date}}</span>
<form ng-show="editing" ng-submit="editing = false">
<label>Name:</label>
<input type="text" ng-model="bday.name" placeholder="Name" ng-required/>
<label>Date:</label>
<input type="date" ng-model="bday.date" placeholder="Date" ng-required/>
<br/>
<button class="btn" type="submit">Save</button>
</form>
</li>这里的关键点是：
当editing
- Added a<>d16>(可以在任何其他元素中)时，我已经将
ng-model -
ng-show更改为本地作用域，并将form添加到span，这样我们就可以在显示它的同时使用ng-hide隐藏内容，这会将editing切换为true - Changed
ng-submit以将editing切换为false
这是您的updated Plunker。

我正在寻找一种内联编辑解决方案，我发现了一个似乎很有前途的柱塞，但它不适合我的开箱即用。在对代码进行了一些修补之后，我让它正常工作了。向最初为编写这部分代码而努力的人致敬。
该示例可在此处http://plnkr.co/edit/EsW7mV?p=preview获得
代码如下：
app.controller('MainCtrl', function($scope) {
$scope.updateTodo = function(indx) {
console.log(indx);
};
$scope.cancelEdit = function(value) {
console.log('Canceled editing', value);
};
$scope.todos = [
{id:123, title: 'Lord of the things'},
{id:321, title: 'Hoovering heights'},
{id:231, title: 'Watership brown'}
];
});
// On esc event
app.directive('onEsc', function() {
return function(scope, elm, attr) {
elm.bind('keydown', function(e) {
if (e.keyCode === 27) {
scope.$apply(attr.onEsc);
}
});
};
});
// On enter event
app.directive('onEnter', function() {
return function(scope, elm, attr) {
elm.bind('keypress', function(e) {
if (e.keyCode === 13) {
scope.$apply(attr.onEnter);
}
});
};
});
// Inline edit directive
app.directive('inlineEdit', function($timeout) {
return {
scope: {
model: '=inlineEdit',
handleSave: '&onSave',
handleCancel: '&onCancel'
},
link: function(scope, elm, attr) {
var previousValue;
scope.edit = function() {
scope.editMode = true;
previousValue = scope.model;
$timeout(function() {
elm.find('input')[0].focus();
}, 0, false);
};
scope.save = function() {
scope.editMode = false;
scope.handleSave({value: scope.model});
};
scope.cancel = function() {
scope.editMode = false;
scope.model = previousValue;
scope.handleCancel({value: scope.model});
};
},
templateUrl: 'inline-edit.html'
};
});指令模板：
<div>
<input type="text" on-enter="save()" on-esc="cancel()" ng-model="model" ng-show="editMode">
<button ng-click="cancel()" ng-show="editMode">cancel</button>
<button ng-click="save()" ng-show="editMode">save</button>
<span ng-mouseenter="showEdit = true" ng-mouseleave="showEdit = false">
<span ng-hide="editMode" ng-click="edit()">{{model}}</span>
<a ng-show="showEdit" ng-click="edit()">edit</a>
</span>
</div>要使用它，只需加水：
<div ng-repeat="todo in todos"
inline-edit="todo.title"
on-save="updateTodo($index)"
on-cancel="cancelEdit(todo.title)"></div>更新：
另一种选择是使用现成的Xeditable for AngularJS：

我已经修改了你的柱塞让它通过angular-xeditable工作
http://plnkr.co/edit/xUDrOS?p=preview
这是内联编辑常见解决方案-您可以使用切换到<input type="text">标记的editable-text指令创建超链接：
<a href="#" editable-text="bday.name" ng-click="myform.$show()" e-placeholder="Name">
{{bday.name || 'empty'}}
</a>对于date，我使用了切换到html5 <input type="date">的editable-date指令。
