Dil*_*eep 6 angularjs angularjs-directive angularjs-ng-repeat
我是角度js的新手,我有一个数组,我通过ng-repeat指令循环它,我已经编写了代码来复制,删除和编辑数组中的值.
如果我想删除或复制我可以做到,完成了吗？但是,如果我单击编辑,将出现一个弹出框,我想编辑那些更新值应该在数组中更新的值.
我怎么能完成它？

$scope.removeStudent=function($index){
$scope.items.splice($index,1);
}
$scope.copyrow=function($index){
$scope.len=$scope.items.length;
$scope.ids=$scope.items[$index].id;
$scope.pnames=$scope.items[$index].pname
$scope.items.push({
id:$scope.len+1,
pname:$scope.pnames

}
$scope.editrow=function($index){
$scope.istrue=true;

$scope.save=function($index){

$scope.s.name=$scope.editedname;
}
});
这是jsfiddle

最简单的方法是在单击编辑时使用angular.copy创建对象的克隆,然后单击"保存"时将数据复制到数组中的项目.
首先启动 $scope.editedItem
$scope.editedItem = {};
因为editrow我们将当前编辑的索引存储在$ index中,然后将数据克隆到$scope.editedItem.
$scope.editrow = function($index){
$scope.istrue = true;
$scope.$index = $index;
angular.copy($scope.items[$index], $scope.editedItem);
}
然后save我们将数据克隆回数组中的对象:
$scope.save = function(){
$scope.istrue = false;
angular.copy($scope.editedItem, $scope.items[$scope.$index])
}
需要更新视图而不是使用editedItem:
<div class="editpopup editpopup-{{istrue}} ">
<p>edit id:<input type="text" ng-model="editedItem.id"></p>
<p>edit pname:<input type="text" ng-model="editedItem.pname"></p>
<button ng-click="save()">save</button>
<button ng-click="closepopup()">cancel</button>
</div>
