而不是顯示爲每個記錄錶行的刪除行，用NG-重複

<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>

而控制器內部直接你可以得到$ index

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

試試這個

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

和控制器

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

在ng-repeat指令中，特殊屬性公開本地作用域包括「$ index」，所以你不需要在remove函數中搜索indexOf項： – etiennecrb

如果在'ng-repeat'中使用過濾器，則不能使用'$ index'。 –

請繞道當前指數在功能

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

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

它會幫助你！

**您可以根據指數**

<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);}
