如何添加嵌套数组的属性

我的逻辑在这里没什么问题。

我有手风琴，我拍了一张照片

enter image description here

标题LIVE BETTING，MLB，MLB道具和NBA都在HTML中（实际上是近25项的体育列表）

  <accordion>
    <accordion-group ng-repeat="sport in sports">
      <accordion-heading>
        <div ng-click="addSportToLines(sport);">
          <span>{{sport.name}}</span>
          <span class="badge">{{sport.leagues.length}}</span>
        </div>
      </accordion-heading>

      <div>
        <a ng-repeat="league in sport.leagues"
           ng-click="addLeagueToLines(league)">
           <span>{{league.name}}</span>
           <span class="badge">{{league.offeringsAvailable}}</span>
        </a>
      </div>
    </accordion-group>
  </accordion>

我需要删除包含<span class=badge>的第一个{{sport.leagues.length}}，并将{{league.offeringsAvailable}}的总和放在那里。 {{league.offeringsAvailable}}是灰色badge中的数字，正如您在MLB中看到的那样：72,30,30,8,30

所以在黄色徽章中，而不是sport.leagues.length我需要league.offeringsAvailable

的总和

这是sports

的控制器 
SportsFactory.getSportsWithLeagues().then(function(sports) {
  $scope.sports = sports;
  console.log(angular.toJson($scope.sports, 'pretty'));
});

这个console.log(angular.toJson($scope.sports, 'pretty'));我得到了这个json

如你所见，标题，例如：LIVE BETTING是第一个，包含一个数组leagues，其中有一个名为offeringsAvailable的道具，所以我需要采用每一个offeringsAvailable }让我们说LIVE BETTING，并将总金额放在$scope变量中，以便在DOM中显示它。

我正在使用LODASH来迭代数组。但我不知道如何完成这项任务

修改

不要混淆，因为我在上面提到了LIVE BETTING，我的意思是，我希望阵列中的每项运动都能发生同样的情况。

尝试：

FuncTest2 <- function(pp) {
    EnvTest$Orig <- ifelse(R[,pp]==0|mat[,pp]!=0,EnvTest$Orig,EnvTest$Orig-(P[,pp]-EnvTest$Orig*R[,pp]/1200));
    return(EnvTest$Orig);
};
EnvTest$Orig <- 548453.5;
Test2 <- rbind(EnvTest$Orig,do.call(rbind,lapply(1:9,FuncTest2)));
x2 <- t(Test2);
x2;

答案 1 :(得分：0)

建议您在收到数据时循环播放每项运动并添加包含总和的offerings属性

sports.forEach(function(sport){ 
    sport.offerings=sport.leagues.reduce(function(prev,curr){     
        return prev + (curr.offeringsAvailable||0);
    },0);
});

然后在标题中使用{{sport.offerings}}
