Toggle class and text in angular.js

angularjs, javascript

Solution

Just use one `li`, and set the class with `ng:class`:

HTML:

<li>
  <a ng:click="toggleLock(selectedUser)">
    <i class="icon" ng:class="{ 'icon-lock': selectedUser.enabled, 'icon-unlock': ! selectedUser.enabled }"></i>
    {{ selectedUser.enabled && 'Lock' || 'Unlock' }}
  </a>
</li>

Javascript:

$scope.toggleLock = function (user) {
     user.enabled ? user.$lock() : user.$unlock();
}

Update: Angular 1.1.5 added support for ternary operators, so the above can be re-written as:

{{ selectedUser.enabled ? 'Lock' : 'Unlock' }}

Problem

There is a lock and unlock functionality, which in html is represented by ``` <li><a ng:click="lock(selectedUser)"><i class="icon-lock icon"></i>Lock</a></li> ``` and ``` <li><a ng:click="unlock(selectedUser)"><i class="icon-unlock icon"></i>UnLock</a></li> ``` Unlock/Lock is acutally a REST API call ``` $scope.unlock = function(user){ user.$unlock(); } $scope.lock = function(user){ user.$lock(); } ``` How can I toggle between the two states in angular.js? I mean when a lock is performed and is successfull the first option should be hidden while the unlock button should get visible. ``` selectedUser.enabled ``` returns `1` for unlocked and `0` for locked.
