    <p>I created a directive for selecting users using bootstrap's drop-down element. as follows.</p> <p><strong>Javascript</strong></p> <pre><code>app.directive('usersDropdown', function(ConfigService,$http) { return { templateUrl: 'app/views/users_dropdown.html', link: function($scope, element, attrs) { }); }; }); </code></pre> <p><strong>users_dropdown.html</strong></p> <pre><code>&lt;div class="btn-group pull-right" &gt; &lt;a class="btn dropdown-toggle" data-toggle="dropdown" href=""&gt; Select User &lt;span class="caret"&gt;&lt;/span&gt; &lt;/a&gt; &lt;ul class="dropdown-menu pull-right align-left" role="menu" aria-labelledby="dropdownMenu"&gt; &lt;li ng-repeat = "userList in userLists"&gt;&lt;a ng-click="getUserDetails('{{userList.SessionId}}')" style="cursor:pointer"&gt;{{userList.UserPartyName}}&lt;/a&gt;&lt;/li&gt; &lt;li ng-hide="userLists" style="cursor:pointer"&gt;&lt;a&gt;No Users&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; </code></pre> <p>I need to create a function <code>getUserDetails</code>, which should be called while clicking on a user from the list. My question is how to define this function inside the directive itself? I wrote it in the controller. But the problem is I am having several controllers. It's not a good practice to write the same function in all controllers. If I can wrote the function common for all controller, that is inside the directive, it will be good. If you have a good solution, let me know that.</p> <hr> <h3>Modification</h3> <p>I modified my directive's js as follows</p> <pre><code>app.directive('usersDropdown', function(ConfigService,$http) { return { templateUrl: 'app/views/users_dropdown.html', link: function($scope, element, attrs) { $scope.getUserDetails = function(user_id){ console.log(user_id); } } }; }); </code></pre> <p>For this I am getting the result in the console as <code>{{userList.SessionId}}</code>. Not the value for that. But when I Inspected the function is passing expected value. <img src="https://i.stack.imgur.com/JYKLl.png" alt="enter image description here"></p> <p>Then why the expected value is not getting inside of that function?</p> <hr> <h3>Solved</h3> <p>I solved the issue by changing my directives html tamplate. I removed <code>'</code> and <code>{{</code> from it as follows.</p> <pre><code>ng-click="getUserDetails(userList.SessionId)" </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
