ng-repeat与动态json数据作为参数接收

Question

我从javascript触发角度函数并尝试重复div。无法找到索引和从javascript返回的数据作为对象。

  var app = angular.module('game',[]);
  app.controller('myCtrl', function($scope) {

  var json = [];
  $scope.setlobbyData = function(obj){
      $scope.json = obj;
      $scope.lobbyData = json;
  };
  });

HTML

<div ng-controller="myCtrl">
<div ng-repeat="i in lobbyData">some data</div>
</div>

JS

var ssr = {
    "0": {
        "tradeSpread": 0,
        "minBuyIn": 10,
        "minPlayers": 2,

    },
    "1": {
        "tradeSpread": 0,
        "minBuyIn": 10,
        "minPlayers": 2,

    }
};
angular.element($("#foreignExchangeMain")).scope().setlobbyData(ssr);

Answer 1

尝试使用ng-if，这将反映在控制器中的集合更新时的视图：

<div ng-repeat="i in lobbyData" ng-if="lobbyData">some data</div>

Answer 2

我使用$ apply函数来更新anugular并且事情得到了更新

var scope = angular.element($("#foreignExchangeMain")).scope();
scope.$apply(function(){
    scope.json = ssr;
    scope.setlobbyData(ssr)

});
