copied!<p>Unfortunately, you cannot save names of directives in string variables and access them in the HTML. You can, however, save a string in a variable in <code>$scope</code> and <a href="http://docs.angularjs.org/api/ng.directive%3angSwitch" rel="nofollow">use <code>ng-switch</code></a> to <em>select</em> the correct directive:</p> <pre class="lang-html prettyprint-override"><code><div ng-switch="dirName"> <div ng-switch-when="ng-user"> <div ng-user></div> </div> <div ng-switch-when="..."> ... </div> </div> </code></pre> <p>However, now it might be better to use something more descriptive than <code>ng-user</code> to <em>switch</em> over.</p> <p><strong>Sidenote:</strong> Do not use <em>ng-</em> prefix in your own directives. Angular uses that prefix so that it does not collide with other namespaces. You should use your own prefix for your directives.</p> <hr> <p><strong>Update</strong>: For the updated question as to why <code><div class="{{dirName}}"></div></code> does not work, it happens because angular <a href="http://docs.angularjs.org/api/ng.%24compile" rel="nofollow"><code>$compile</code>s the directive</a> only once. If you first <a href="http://docs.angularjs.org/api/ng.%24interpolate" rel="nofollow"><code>$interpolate</code></a> the content of the template (which will replace <code>{{dirName}}</code> with <code>ng-user</code>) and then explicitly <code>$compile</code> it before entering it in the HTML, it should work.</p>
