Edit In Place Content Editing
HtmlAngularjsEditHtml Problem Overview
When using ng-repeat what is the best way to be able to edit content?
In my ideal situation the added birthday would be a hyperlink, when this is tapped it will show an edit form - just the same as the current add form with an update button.
HTML:

<body ng-app="birthdayToDo" ng-controller="main">
<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 = '';
$scope.bdaydate = '';
};
});
Html Solutions
Solution 1 - Html
You should put the form inside each node and use ng-show and ng-hide to enable and disable editing, respectively. Something like this:
<li>
<span ng-hide="editing" ng-click="editing = true">{{bday.name}} | {{bday.date}}</span>
<form ng-show="editing" ng-submit="editing = false">
<label>Name:</label>
<input type="text" ng-model="bday.name" placeholder="Name" ng-required/>
<label>Date:</label>
<input type="date" ng-model="bday.date" placeholder="Date" ng-required/>
<br/>
<button class="btn" type="submit">Save</button>
</form>
</li>
The key points here are:
- I've changed controls
ng-modelto the local scope - Added
ng-showtoformso we can show it while editing - Added a
spanwith ang-hideto hide the content while editing - Added a
ng-click, that could be in any other element, that toggleseditingtotrue - Changed
ng-submitto toggleeditingtofalse
Here is your updated Plunker.
Solution 2 - Html
I was looking for a inline editing solution and I found a plunker that seemed promising, but it didn't work for me out of the box. After some tinkering with the code I got it working. Kudos to the person who made the initial effort to code this piece.
The example is available here http://plnkr.co/edit/EsW7mV?p=preview
Here goes the code:
app.controller('MainCtrl', function($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;
$timeout(function() {
elm.find('input')[0].focus();
}, 0, false);
};
scope.save = function() {
scope.editMode = false;
scope.handleSave({value: scope.model});
};
scope.cancel = function() {
scope.editMode = false;
scope.model = previousValue;
scope.handleCancel({value: scope.model});
};
},
templateUrl: 'inline-edit.html'
};
});
Directive template:
<div>
<input type="text" on-enter="save()" on-esc="cancel()" ng-model="model" ng-show="editMode">
<button ng-click="cancel()" ng-show="editMode">cancel</button>
<button ng-click="save()" ng-show="editMode">save</button>
<span ng-mouseenter="showEdit = true" ng-mouseleave="showEdit = false">
<span ng-hide="editMode" ng-click="edit()">{{model}}</span>
<a ng-show="showEdit" ng-click="edit()">edit</a>
</span>
</div>
To use it just add water:
<div ng-repeat="todo in todos"
inline-edit="todo.title"
on-save="updateTodo($index)"
on-cancel="cancelEdit(todo.title)"></div>
UPDATE:
Another option is to use the readymade Xeditable for AngularJS:
Solution 3 - Html
I've modified your plunker to get it working via angular-xeditable:
http://plnkr.co/edit/xUDrOS?p=preview
It is common solution for inline editing - you creale hyperlinks with editable-text directive
that toggles into <input type="text"> tag:
<a href="#" editable-text="bday.name" ng-click="myform.$show()" e-placeholder="Name">
{{bday.name || 'empty'}}
</a>
For date I used editable-date directive that toggles into html5 <input type="date">.
Solution 4 - Html
Since this is a common piece of functionality it's a good idea to write a directive for this. In fact, someone already did that and open sourced it. I used editablespan library in one of my projects and it worked perfectly, highly recommended.
