Question

使用ng-repeat时，哪种方式可以编辑内容？

在我理想的情况下，添加生日将是一个超链接，当点击它时，它将显示一个编辑表单 - 与当前添加表单和更新按钮相同。

    <div id="wrap">

      <!-- Begin page content -->
      <div class="container">
        <div class="page-header">
          <h1>Birthday Reminders</h1>
        </div>
            <ul ng-repeat="bday in bdays">
                <li>{{bday.name}} | {{bday.date}}</li>
            </ul>

           <form ng-show="visible" ng-submit="newBirthday()">
            <label>Name:</label>
            <input type="text" ng-model="bdayname" placeholder="Name" ng-required/>
            <label>Date:</label>
            <input type="date" ng-model="bdaydate" placeholder="Date" ng-required/>
            <br/>
            <button class="btn" type="submit">Save</button>
        </form>
      </div>

      <div id="push"></div>
    </div>

    <div id="footer">
      <div class="container">
        <a class="btn" ng-click="visible = true"><i class="icon-plus"></i>Add</a>
      </div>
    </div>
    </body>

App.js：

var app = angular.module('birthdayToDo', []);

app.controller('main', function($scope){ 

    // Start as not visible but when button is tapped it will show as true 

        $scope.visible = false;

    // Create the array to hold the list of Birthdays

        $scope.bdays = [];

    // Create the function to push the data into the "bdays" array

    $scope.newBirthday = function(){

        $scope.bdays.push({name:$scope.bdayname, date:$scope.bdaydate});

        $scope.bdayname = '';
        $scope.bdaydate = '';

    };
});

您应该将表单放在每个节点中，并分别使用ng-show和ng-hide启用和禁用编辑。像这样：

<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：

我已将控件ng-model更改为本地范围
将ng-show添加到form，以便我们在编辑时显示
添加了span ng-hide以隐藏编辑内容时的内容
添加ng-click，可以在任何其他元素中，将editing切换为true
将ng-submit更改为切换editing至false

这是您的updated Plunker。

我一直在寻找一个内联编辑解决方案，我找到了一个看起来很有前途的傻瓜，但它并不适合我开箱即用。经过一些修改代码后，我得到了它的工作。感谢最初努力编写这篇文章的人。

此处提供了示例http://plnkr.co/edit/EsW7mV?p=preview

以下是代码：

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>

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：

Answer 3

我修改了你的plunker，让它通过angular-xeditable：

运行

http://plnkr.co/edit/xUDrOS?p=preview

这是内联编辑的常用解决方案 - 您使用editable-text指令创建超链接切换到<input type="text">标记：

<a href="#" editable-text="bday.name" ng-click="myform.$show()" e-placeholder="Name">
    {{bday.name || 'empty'}}
</a>

对于约会，我使用editable-date指令切换到html5 <input type="date">。

Answer 4

由于这是一个常见的功能，因此为此编写指令是个好主意。事实上，有人已经这样做并开源了。我在editablespan中使用了one of my projects库，它非常有效，强烈推荐。
