Answer 1

不要显示每条记录的表格行，而是使用ng-repeat

<tr ng-repeat="emp in emplist">
  <td>{{emp.name}}</td>
  <td>{{emp.name}}</td>
  <td>{{emp.name}}</td>
  <td><button ng-click="remItem($index)">Remove</button></td>

在控制器内直接你可以得到$ index

$scope.remItem = function(itemIndex){
  $scope.emplist.splice(itemIndex,1);
}

Answer 2

请在您的功能中传递当前索引

$html .= '<option value=""></option>';

它会帮助你!!!

Answer 3

试试这个

<button ng-click="remItem(x);" > Remove</button>

并在控制器中

  $scope.remItem = function(item){
    var index = $scope.emplist.indexOf(item);
    $scope.emplist.splice(index,1);
  }

Answer 4

**您可以根据索引**

删除该行

 <button title="Remove" ng-click="removeFile($index)"></button>


$scope.removeFile = function (index) {
    if (!confirm("Are you sure you want to remove?")) {
        return;
    }
    $scope.emplist.splice(index, 1);}
