angularjs - When old label does not match new label add row to table -


i'm looking angularjs code.

when {{notification.label}} changes 1 value (the content of table database) add new row. can't work , because don't know how done. preferably close table , create new 1 because loop in tr i'm guessing not possible.

looking direction , maybe example. experimented if directive wasn't able compare old label new label.

<div id=postmodule data-ng-app="postmodule" data-ng-controller="postcontroller" data-ng-init="init()"     <form novalidate name="notificationform">         <table class="table table-bordered table-hover table-striped">             <tr data-ng-repeat="notification in post.notification | orderby : 'label'">                 <td>                     {{notification.label}}                 </td>                 <td>                     {{notification.vendor}}                 </td>                  <td>                     {{notification.product}}                 </td>                    <td>                     {{notification.version}}                 </td>                                                <td>                     {{notification.cve}}                 </td>                 <td>                     {{notification.cvsscore}}"                 </td>             </tr>         </table>     </form> </div>

database:

notification.label || notification.vendor || notification.product expensive          || samsung             || galaxy expensive          || apple               || iphone budget             || huawai              || x budget             || huawai              || y

i see (table)

notification.label || notification.vendor || notification.product expensive          || samsung             || galaxy expensive          || apple               || iphone  notification.label || notification.vendor || notification.product budget             || huawai              || x budget             || huawai              || y

and better when 2 seperated tables

notification.label || notification.vendor || notification.product expensive          || samsung             || galaxy expensive          || apple               || iphone   notification.label || notification.vendor || notification.product budget             || huawai              || x budget             || huawai              || y

you can use groupby achieve this. 

// code goes here    angular.module('app',['angular.filter'])    .controller('maincontroller', function($scope) {             $scope.notifications = [{          label: 'expensive',          vendor: 'samsung             '      }, {          label: 'expensive',          vendor: 'sony'      }, {          label: 'expensive',          vendor: 'moto'      }, {          label: 'budget',          vendor: 'iphone'      }, {          label: 'budget',          vendor: 'x'      }];         });
.custom{  margin-bottom:0px !important;  }  .custom>tbody>tr>th  {     width: 50%;      float: left;      border: none !important;  }

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
