Angularjs：如何拆分任何数组列表的一半

Question

我目前将 json 中的列表拆分为前 10 个，第二个是 11 到 20。但是，对于列表的任何长度，我想将其拆分为一半。我该怎么做？

这是我的代码

  function loadTop() {
    $webServicesFactory.get($marketProvider[$scope.currentMarket].topGetURL, {AnonymousToken: $marketProvider[$scope.currentMarket].token}).then(
      function success(response) {
        $scope.top = response.Stock.slice(0, 10);
        $scope.low = response.Stock.slice(10, 20);
        console.log($scope.top);
        loadStockCount();
        loadTop();
        loadLow();
        $ionicLoading.hide();
      },
      function error(error) {
        $ionicLoading.hide();
      }
    );
  }

Answer 1

var numStocks = response.Stock.length;
var halfStocks = Math.round(numStocks / 2);
$scope.top = response.Stock.slice(0, halfStocks);
$scope.low = response.Stock.slice(halfStocks, numStocks);
