集团和领域

我有这样一个JSON，我想它的标志值集团和领域

$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 
     } 
    ]

计算字段的总和，组和我的HTML是这样在这里我想要什么当用户把价值常驻现场应该找到它标志值，并计算常驻领域的总和与标志值，如果标志值是1个放总和wspStaffTotal.Admin_Perm_Total，如果标志值是2将总和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">

是我的尝试是

$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); 
      } 
    } 
}) 
}

但预计它无法正常工作。

运行在每此功能陈ge会花费你很多的表现... –

是啊我知道有没有其他方式？ – sanu

反跳才能解决您的性能问题... https://lodash.com/docs/4.16.4#debounce –

我希望这是你希望的东西...

app.js

var myApp = angular.module('test' , []); 
myApp.controller('test_ctrl' , function($scope){ 
    $scope.staffs = [ 

     { 
      "id": 1, 
      "name": "Management", 
      "Flag": 1 
     }, 
     { 
      "id": 2, 
      "name": "Revenue Collection/Ledger", 
      "Flag": 1 
     }, 
     { 
      "id": 3, 
      "name": "Office Assistance",

      "id": 6, 
      "name": "Operators at Networks", 
      "Flag": 2 
     } 
    ]; 

    $scope.updatePermanentTotal = function(){ 
     $scope.wspStaffTotal = { 
      Admin_Perm_Total: 0, 
      Technical_Perm_Total :0 
     } 

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

      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); 
       } 
      }else{ 
       console.log("value is NAN"); 
      } 

     }); 
     alert("result flag1:{" +$scope.wspStaffTotal.Admin_Perm_Total+"} flag2: {" +$scope.wspStaffTotal.Technical_Perm_Total +"}"); 
    }

什么是你的代码和我的不同？ – sanu

$ scope.wspStaffTotal = { Admin_Perm_Total：0， Technical_Perm_Total：0 } 使其工作你试试我的吗？ –

它正在工作。怎么样？ – sanu

首先使永久值在控制器的阵列

$scope.webStaffTbl.Permanent = [];

然后传递这些将值给该函数：

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

，并用它的标志的永久值传递给函数

然后在$ scope函数中这样做：

$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){ 

      } 
    } 
}) 
}
