Question

我想访问嵌套ng-repeat的范围。具体点击的项目。我该如何实现？

<div ng-repeat="item in list" ng-click="get(item)">
    <div ng-repeat="book in books" ng-click="get(book)">
        {{book.name}}
    </div>
</div>

和控制器

$scope.get = function(item){
       console.log(item);
};

我只能获得项目范围，如何获得书籍范围？如果我同时应用这两个功能，则会触发这两个功能，我只想要单击的项目。

示例

$scope.json = {
  "data": {
    "books": [
      {
        "id": "1",
        "name": "Tom",
        "pub": "Cruise",
        "photo": ".jpg",
        "topics": [
          {
            "id": "1",
            "pages": "31"
          },
          {
            "id": "2",
            "pages": "300"
          }
        ]
      },
      {
        "id": "2",
        "name": "Maria",
        "pub": "Sharapova",
        "photo": ".jpeg",
        "topics": [
          {
            "id": "1",
            "pages": "321"
          },
          {
            "id": "2",
            "pages": "500"
          }
          ...
        ]
      }
    ]
  }
}

它可以嵌套得更多。

<div ng-repeat="book in json.data.books" ng-click="get(book)">
    <div><bold>{{book.name}}</bold></div>
    <div ng-repeat="topic in book" ng-click="get(topic)">
        {{topic.pages}}
    </div>
</div>

它给我这样的结果，

Tom
31
300

Maria
321
500

现在，如果我单击31，则仅需要使用

主题对象

 function get(topic){
      console.log(topic);
   }

console:
    {
      "id": "1",
      "pages": "31"
    }

如果我单击“汤姆”，则需要本书的范围

 function get(book){
          console.log(book);
     }

结果应该像这样

{
        "id": "1",
        "name": "Tom",
        "pub": "Cruise",
        "photo": ".jpg",
        "topics": [
          {
            "id": "1",
            "pages": "31"
          },
          {
            "id": "2",
            "pages": "300"
          }
        ]
      }

Answer 1

将ng-click移动到内部元素：

<div ng-repeat="book in json.data.books">
    <div ng-click="get(book)"><b>{{book.name}}</b></div>
    <div ng-repeat="topic in book.topics">
        <div ng-click="get(topic)">{{topic.pages}}</div>
    </div>
</div>

正在运行的演示：demo

Answer 2

您可以创建如下函数：

function get(topic, refItem){
    console.log(topic);
    if (refItem) {
        console.log(refItem); 
        //or console.log(JSON.stringify(refItem);
    }
}

<div ng-repeat="book in json.data.books" ng-click="get(book)">
    <div><bold>{{book.name}}</bold></div>
    <div ng-repeat="topic in book" ng-click="get(topic, book)">
        {{topic.pages}}
    </div>
</div>

或者您可以创建2个或更多这样的函数：

function getBook(book){
    console.log(book);
}

function getTopic(topic, book){
    console.log(topic);
    console.log(book);
}

<div ng-repeat="book in json.data.books" ng-click="getBook(book)">
    <div><bold>{{book.name}}</bold></div>
    <div ng-repeat="topic in book" ng-click="getTopic(topic, book)">
        {{topic.pages}}
    </div>
</div>

如何从嵌套ng-repeat中访问项目？
