    <p>I have a list of three inputs, each of them can be deleted by the user by pressing a red cross placed at the left side of them. When the user delete one input, the next one is focused and the selected checkbox is deleted. Until there so far so good. After deleting the element the ng-repeat loop iterates over the updated model and I lose the element focus. Is there any way to prevent this?</p> <p>Thanks so much,</p> <p>Guillermo</p> <p>PD: Including the directive code just in case.</p> <pre><code>directive('checkEmptyInput', function ($timeout,$q) { return { restrict: 'A', require: '?ngModel', link: function (scope, element, attrs, ngModel) { if(!ngModel) return; //do nothing if no ng-model var idx = scope.$index, array = [], fieldIsValid = false; element.on('keyup', function () { switch (attrs.checkEmptyInput) { case "method": array = scope.album.tracks; fieldIsValid = scope.ngAlbumForm.track.$valid; break; } if(array[idx].name &amp;&amp; array[idx].name != "" &amp;&amp; fieldIsValid) { array[idx].active = true; } else { array[idx].active = false; if(scope.elementHasId(array[idx])){ scope.deleteKeyFromCombinationsCodes(array[idx].id); } }; if (array[idx].name == "") { //Previous to delete focus the next element $timeout(function () { var nextElem = element.parent().next().find('input')[0]; if(nextElem !== undefined) { if(!scope.$last) { //Delete the element console.log("Deleting from inside the directive..."); nextElem.focus(); scope.$emit("deleteArrayElement", [idx]); } } }); } }); } } }) </code></pre> <p>HTML:</p> <pre><code> &lt;div ng-repeat="track in album.tracks"&gt; &lt;input check-empty-input="track" type="text" ng-change="addInputText($index,$last,track.name,album.tracks;" ng-minlength="3" class="album_tracks" ng-model="track.name" ng-unique="track"/&gt;&lt;button type="button"/&gt; &lt;i class="remove-icon"&gt;&lt;/i&gt; &lt;/button&gt; &lt;/div&gt; </code></pre> <p>Plunker: <a href="http://plnkr.co/edit/BRN9csBcxHp5QU96NKq9?p=info" rel="nofollow">http://plnkr.co/edit/BRN9csBcxHp5QU96NKq9?p=info</a></p>

    1. COlooks like you misunderstood angular directives : "element.on('keyup', " should be inside directive template as ngkeyup (http://docs.angularjs.org/api/ng.directive:ngKeyup) and every interaction as separate function. Can you provide jsfiddle so we can see html also?

    2. CODaniel: Thanks so much, the code works as expected, but the undesired behavior is that I lose the focus on the element once the ng-repeat renders again the updated model after deleting the selected option. I've added the html snippet

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.
