无法在 table -AngularJS 中显示正确的数据

Question

下面是我的 plunker，我试图在其中显示每个 category.But 数据未按预期打印的数据。示例：-rom 值 12345 应该直接位于面包下。我不确定我的代码哪里做错了：

  $scope.allProducts = [];
  angular.forEach($scope.data,function(item, index){
    angular.forEach(item.products, function(item2, index){
      if($scope.allProducts.indexOf(item2.consummable) == -1){
        $scope.allProducts.push(item2.consummable);
      }
    })
  })

Creating a table matrix

Answer 1

请检查结构：

 <table style="border : 1px solid">
<tr>
  <td></td>
  <td ng-repeat="product in allProducts">
    {{product.consummable}}
  </td>
</tr>
<tr ng-repeat="test in data">

  <td>{{test.resource}}</td>
  <td ng-repeat="pro in allProducts">{{pro.rom}}</td>
</tr>

并且只需在 allProducts 中推送 item2 而不是仅在 consummable 字段中推送 :

 angular.forEach($scope.data,function(item, index){
angular.forEach(item.products, function(item2, index){
  if($scope.allProducts.indexOf(item2.consummable) == -1){
    $scope.allProducts.push(item2); // Here I have pushed item2 instead of item2.consummable
  }
})

})

Answer 2

另一个变体 ng-repeat 表达式。由于您在第一行重复了 allProducts，因此您需要重复它并在其他行中重复，并为所选值过滤数据。请参阅下面的代码片段

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';
  $scope.data =[
    {
        "resource": "100",
        products: [
            {
                "consummable": "milk",
                 "rom": 1
            },
         
        ]
    },
    {
        "resource": "200",
        products: [
        
            {
                "consummable": "bread",
                 "rom": 12345
            },
           
        ]
    },
    {
        "resource": "300",
        products: [
      
            {
                "consummable": "butter",
                 "rom": 123456789
            }
        ]
    }
];

  $scope.allProducts = [];
  angular.forEach($scope.data,function(item, index){
    angular.forEach(item.products, function(item2, index){
      if($scope.allProducts.indexOf(item2.consummable) == -1){
        $scope.allProducts.push(item2.consummable);
      }
    })
  })

});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.17/angular.min.js"></script>
<div ng-app="plunker" ng-controller="MainCtrl">
  <p>Hello {{name}}!</p>

  <table style="border:1px solid red;">
    <tr>
      <td>
      </td>
      <td ng-repeat="itemProd in allProducts" style="border:1px solid red;">
        {{itemProd}}
      </td>
    </tr>
    <tr ng-repeat="item in data">
      <td>
        {{item.resource}}
      </td>
      <td ng-repeat="item2 in allProducts" style="border:1px solid red;" ng-init="product=(item.products | filter: {consummable:item2})[0]">
        <a>{{product.rom}}</a>
      </td>
    </tr>
  </table>
  {{allProducts}}
  {{data}}
  
</div>

Answer 3

您需要的解决方案如下：

1) 保持 allProducts 生成如下：

  $scope.allProducts = [];
  angular.forEach($scope.data,function(item, index){
    angular.forEach(item.products, function(item2, index){
      if($scope.allProducts.indexOf(item2.consummable) == -1){
        $scope.allProducts.push(item2.consummable);
      }
    })
  })

2) 在您的控制器中添加：

$scope.getColumnValue = function(item,item2, index) {
   var returnVal;
    angular.forEach(item.products, function(val, index){
     if(item2 == val.consummable){
       returnVal = val.rom;
     }
   })
   return returnVal;
 }

3) table 代将是：

<table style="border:1px solid red;">
   <tr>
     <td>
     </td>
     <td ng-repeat="itemProd in allProducts" style="border:1px solid red;">
       {{itemProd}}
     </td>
   </tr>
   <tr ng-repeat="item in data">
     <td>
       {{item.resource}}
     </td> 
     <td ng-repeat="item2 in allProducts" style="border:1px solid red;">
       <a>{{getColumnValue(item, item2)}}</a>
      </td>
   </tr>
 </table>
