javascript - 隐藏数组的最后一个元素

Question

如何隐藏数组的最后一个索引，因为我想隐藏标签并在用户单击添加按钮时显示输入。找不到帮助。这是我的代码:-

<tr ng-repeat="personalDetail in personalDetails">
    <td> 
        <label ng-show="lab[$index]=true" for="settings" > {{personalDetail.Sname}}</label>
        <input ng-show="lab[$index]=false" type="text" ng-model="personalDetail.Sname" />
    </td>
    <input type="button" class="btn btn-primary addnew pull-right btn-space" ng-click="addNew($index)" value=" Add New">

还有我的 Angular 代码:

$scope.addNew = function(val) {
   $scope.personalDetails.push({
      'Sname': "",
      'Settings': "",
   });
   var ind = $scope.personalDetails.length - 1;
   $("label[data-val='" + ind + "']").hide();
   $("input[data-val='" + ind + "']").show();
   $scope.PD = {};
};

试试这个

<tr ng-repeat="personalDetail in personalDetails">
<td> 
<label ng-hide="$last" for="settings" > {{personalDetail.Sname}}</label>
<input ng-show="$last"  type="text" ng-model="personalDetail.Sname" />
</td>
<tr>
