I have a table and using jquery ( sortable ), I’d like when you drag the line by modifying the html of the table, the order of the array change

Example:

CAMPO1

CAMPO2 /// DRAG THIS ONE DOWN

CAMPO3 /// SOON THIS ONE GOES UP

ARRAY ORIGINAL: [{id:1, campo:1},{id:2, campo:2},{id:3, campo:3}]

ARRAY DEPOIS : [{id:1, campo:1},{id:3, campo:3},{id:2, campo:3}]

Code example:

<html ng-app="listagemIndex" style="background-color: #FFF;" ng-cloak>
<met charset="UFT-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<head>
<title ng-bind="apps"></title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.1/angular.min.js"></script>
<script>
angular.module("listagemIndex", []);
angular.module("listagemIndex").controller("listagemIndexControl", function ($scope){

$scope.conjunto = [{id:1, nome:"ana1"},{id:2, nome:"ana2"},{id:3, nome:"ana3"},{id:4, nome:"ana4"}];

    $( "#sortable" ).sortable();
    $( "#sortable" ).disableSelection();
  } );
</script>
</head>

<body class="container-fluid" ng-controller="listagemIndexControl">




<table  class="table table-striped">
  <thead>
    <tr>
      <th>ID</th>
      <th>NOME</th>
    </tr>
  </thead>
  <tbody id="sortable">
    <tr ng-repeat="obj in conjunto | orderBy: obj.nome" >
    <td>{{obj.id}}</td>
      <td><input type="text" ng-model="obj.nome"></td>
    </tr>
  </tbody>
</table>

</body>

Use one more javascript the ui.sortable, is responsible for the changes in its collection including changing the indexation of the elements according to the new position.

Define the directive in your module ui.sortable, as an example:

angular.module("listagemIndex", ['ui.sortable'])

and in the tag tbody include these two settings:

<tbody ui-sortable="" ng-model="conjunto">

Minimal example:

angular.module("listagemIndex", ['ui.sortable'])
  .controller("listagemIndexControl",
    function($scope) {
      $scope.conjunto = [{
        id: 1,
        nome: "ana1"
      }, {
        id: 2,
        nome: "ana2"
      }, {
        id: 3,
        nome: "ana3"
      }, {
        id: 4,
        nome: "ana4"
      }];

    });

<div id="lista" ng-app="listagemIndex" ng-controller="listagemIndexControl">
  <table class="table table-striped">
    <thead>
      <tr>
        <th>Index</th>
        <th>ID</th>
        <th>NOME</th>
      </tr>
    </thead>
    <tbody ui-sortable="" ng-model="conjunto">
      <tr ng-repeat="obj in conjunto | orderBy: obj.nome">
        <td>{{$index}}</td>
        <td>{{obj.id}}</td>
        <td>
          <input type="text" ng-model="obj.nome">
        </td>
      </tr>
    </tbody>
  </table>
</div>

^{Observing: that way you don’t need to use more $("#sortable").sortable(); the angular be responsible.}
