Question

我有一个这样的json，我想计算字段的总和，按标志值分组

$scope.staffs =  [

        {
            "id": 1,
            "name": "Management",
            "Flag": 1
        },
        {
            "id": 2,
            "name": "Revenue Collection/Ledger",
            "Flag": 1
        },
        {
            "id": 3,
            "name": "Office Assistance",
            "Flag": 1
        },
        {
            "id": 4,
            "name": "Operators (Source)",
            "Flag": 2
        },
        {
            "id": 5,
            "name": "Operators (WTP)",
            "Flag": 2
        },
        {
            "id": 6,
            "name": "Operators at Networks",
            "Flag": 2
        }
    ]

我的html就像这样我想要的是当用户将值放到Permanent字段时它应该找到它的Flag值并计算具有该Flag值的Permanent字段的总和，如果Flag值为1则将sum加入 wspStaffTotal.Admin_Perm_Total ，如果标记值为2则将总和加到 wspStaffTotal.Technical_Perm_Total

<div ng-repeat="wspStaffTbl in staffs">
{{ wspStaffTbl.name }}
<input type="text" ng-model="wspStaffTbl.Permanent" ng-change="updatePermanentTotal()">
</div>

<input type="text" ng-model="wspStaffTotal.Admin_Perm_Total">
<input type="text" ng-model="wspStaffTotal.Technical_Perm_Total">

我试过的是

$scope.updatePermanentTotal = function(){
  $scope.wspStaffTotal.Admin_Perm_Total = 0;
  $scope.wspStaffTotal.Technical_Perm_Total = 0;

  angular.forEach($scope.staffs, function(value, key){

    if(!isNaN(parseInt(value.Permanent))){
       if(value.Flag==1){
            $scope.wspStaffTotal.Admin_Perm_Total = $scope.wspStaffTotal.Admin_Perm_Total + parseInt(value.Permanent);
          }
    if(value.Flag==2){
            $scope.wspStaffTotal.Technical_Perm_Total = $scope.wspStaffTotal.Technical_Perm_Total + parseInt(value.Permanent);  
          }
    }
 })
}

但它没有按预期工作。

Answer 2

首先使永久值成为控制器中的数组

$scope.webStaffTbl.Permanent = [];

然后将这些传递给函数的值：

<input type="text" ng-model="wspStaffTbl.Permanent[$index]" ng-change="updatePermanentTotal(wspStaffTbl.Permanent[$index],wspStaffTbl.flag)">

并将带有标志的永久值传递给函数

然后在$ scope函数中执行以下操作：

$scope.updatePermanentTotal = function(permanentValue,flag){


$scope.wspStaffTotal.Admin_Perm_Total = 0;
  $scope.wspStaffTotal.Technical_Perm_Total = 0;

  angular.forEach($scope.staffs, function(value, key){

    if(!isNaN(parseInt(permanentValue))){
       if(flag==1){

            $scope.wspStaffTotal.Admin_Perm_Total = $scope.wspStaffTotal.Admin_Perm_Total + parseInt(permanentValue);
          }
    if(flag==2){

          }
    }
 })
}

ng-repeat中的分组和求和字段
