使用 $index 和 $parent.$index 在 ng-repeat 和 child ng-repeat 中动态创建 ng-model?

create ng-model dynamically in ng-repeat and child ng-repeat using $index and $parent.$index?

当我单击“保存”并添加另一个项目按钮时,我有带有一些输入字段和复选框的表单控制器我正在一次复制(克隆)整个表单控制器。可以做n次。我正在创建一个数组,当我单击按钮时推送表单元素

 <div class="row category-description-block" ng-repeat="values in categoryval.CategoryValuesArray track by $index">

在表单控制器中,当我单击复选框时,我有一个复选框,有一个 form-input 字段称为数量并添加另一个项目 button.You 可以使用它来创建 n 个 quantity.I 我正在使用一个 ng-repeat 将值推入另一个数组。

 $scope.addJewelryDetails = newJewelryDetails;
$scope.globalAppend = newGlobalDiv;


$scope.IsVisible = [];
$scope.categoryval = {
    jewelrymoreDetailschecked: false
};

$scope.jewelrymoreDetailsChange = function(index) {
    $scope.IsVisible[index] = $scope.categoryval.jewelrymoreDetailschecked[index];

};


$scope.categoryContinue = function(categoryvalues) {
    console.log(categoryvalues);
};



       $scope.categoryval = {};
     // $scope.categoryval.jewelryCollection = {};
    $scope.categoryval.images = [];
     $scope.categoryval.CategoryValuesArray = [];
      $scope.categoryval.moreJewelryDetailsArray = [];
      $scope.categoryval.quantity = [];

function init() {

    newJewelryDetails();
    newGlobalDiv();
}

function newGlobalDiv() {

    $scope.categoryval.CategoryValuesArray.push({});
}

function newJewelryDetails(parentindex) {

    $scope.categoryval.moreJewelryDetailsArray.push({});
    $scope.quantity = '';

}
$scope.removeItem = function(parentindex,index) {
    console.log(JSON.stringify(parentindex));

   $log.log("parent Index:::" + parentindex + "index::::" +  index);


  //var quantity =       $scope.categoryval.moreJewelryDetailsArray[index].quantity;     
   $scope.categoryval.moreJewelryDetailsArray.splice(index,1);

};  


init();

但我对数量字段的添加和删除有疑问。例如 Parent1 有 3 个数量字段,parent2 有 3 个数量。每个 parent 都有独立的数量。当我从 parent2 中删除第二个数量时,它也会从 parent1 中删除。我只想单独删除 parent 2 和 parent1 并添加数量字段。我的完整工作 fiddle 在这里 codepen。任何人为我提供解决方案提前感谢

不要为这种逻辑使用多维数组。 Javascript/Json 适合这份工作。

您应该有一个包含项目列表的珠宝数组:

[
  {
    items: [{name: "", description: ""}, {name: "", description: ""}]
  },
  {
    items: [{name: "", description: ""}, {name: "", description: ""}]
  }
]

您以相同的方式删除项目:

$scope.removeItem = function(parentindex,index) {
   $scope.jewelryArray[parentIndex].items.splice(index,1);
};
