Question

嗨，我有一个如下所示的数组

$scope.Selectedgroups =[183,184,24]

我需要转换为以下格式

 [{groupId:183},{groupId:184},{groupId:24}];

尝试使用for循环

进行转换

var groups=[]
        if($scope.Selectedgroups.length > 0){
            for(i=0; i< $scope.Selectedgroups.length; i++){
                groups.push({"groupId":$scope.Selectedgroups});
            }
        }

获取如下数组格式：

[{"groupId":[183,184,24]},{"groupId":[183,184,24]},{"groupId":[183,184,24]}]

任何解决方案

Answer 1

这一行存在问题：

 groups.push({"groupId":$scope.Selectedgroups});

请将此更改为：

 groups.push({"groupId":$scope.Selectedgroups[i]});

Answer 2

使用索引访问数组位置，例如$scope.Selectedgroups[i]

for(i=0; i< $scope.Selectedgroups.length; i++){
      groups.push({"groupId":$scope.Selectedgroups[i]});
}

Answer 3

您应该将特定的 index 值更改为

groups.push({"groupId":$scope.Selectedgroups[i]});

Answer 4

use --  $scope.Selectedgroups[i]     

         var groups=[]
            if($scope.Selectedgroups.length > 0){
                for(i=0; i< $scope.Selectedgroups.length; i++){
                    groups.push({"groupId":$scope.Selectedgroups[i]});
                }
            }

Mat inImg = imdecode(new Mat(imageData),IMREAD_UNCHANGED);
Mat outImg = Mat.zeros(inImg.size(), CV_8UC3).asMat();

UByteIndexer inIndexer = inImg.createIndexer();
UByteIndexer outIndexer = outImg.createIndexer();

for (int i = 0; i < inIndexer.rows(); i++) {
    for (int j = 0; j < inIndexer.cols(); i++) {
        int[] pixel = new int[4];
        try {
            inIndexer.get(i, j, pixel);
            if (pixel[3] == 0) { // transparency
                pixel[0] = pixel[1] = pixel[2] = 255;
            }
            outIndexer.put(i, j, pixel);
        } catch (IndexOutOfBoundsException e) {

        }
    }
}

var app = angular.module('testApp',[]);
app.controller('testCtrl',function($scope){
 $scope.Selectedgroups =[183,184,24];
  $scope.temp=[];
 $scope.Selectedgroups.forEach(function(e){
    $scope.temp.push({groupId:e});
 })
 $scope.Selectedgroups=$scope.temp;
 console.log($scope.Selectedgroups);
});

Answer 6

问题是，您应该将特定的值索引推送到groups数组。所有其他答案都解释得很好。

但我有另一个答案，您可以使用map()函数来减少loop语句和几行代码。

  var app = angular.module('testApp',[]);
    app.controller('testCtrl',function($scope){
     $scope.Selectedgroups =[183,184,24];
     var groups=[]
      if($scope.Selectedgroups.length > 0){          
      groups = $scope.Selectedgroups.map(function(elem){    
         return {"groupId":elem};
      });
     }
     console.log(groups);
    });

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
    <body ng-app="testApp" ng-controller="testCtrl">

    </body>

		var items = [183,184,24];
		for(i=0; i< items.length; i++){
