Question

我遇到了与

类似的问题

The $scope variable is undefined unless I forced it to retrieve from service again

当我试图从服务中调用某个功能时，我从角度js得到以下错误

TypeError: $scope.watchlist.addStock is not a function

这是我的控制器

angular.module('stockDogApp')
  .controller('WatchlistCtrl', function ($scope,$routeParams,$modal,WatchlistService,CompanyService) {
    $scope.companies = CompanyService.query();
    $scope.watchlist = WatchlistService.query($routeParams.listId);
    console.log($scope.watchlist);
    $scope.stocks = $scope.watchlist.stocks;
    $scope.newStock = {};
    var addStockModal = $modal({
      scope : $scope,
      templateUrl : 'views/templates/addstock-modal.html',
      show: false
    });

    $scope.showStockModal = function(){
      addStockModal.$promise.then(addStockModal.show);
    };

    $scope.addStock = function(){
      $scope.watchlist.addStock({
        listId : $routeParams.listId,
        company: $scope.newStock.company,
        shares: $scope.newStock.shares
      });
      addStockModal.hide();
      $scope.newStock = {};
    };

当我记录$ scope.watchlist时 - 该对象确实存在于对象

中

Object {name: "Saklep", description: "Saklep", id: 0, stocks: Array[0]}
addStock: function(stock)
arguments: (...)
caller: (...)
length: 1
name: ""

这是模态窗口的html

<div class="modal" tabindex="-1" role="dialog">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" ng-click="$hide()">&times;</button>
        <h4 class="modal-title">Add New Stock</h4>
      </div>

      <form role="form" id="add-stock" name="stockForm">
        <div class="modal-body">
          <div class="form-group">

            <input type="text"
              class="form-control"
              id="stock-symbol"
              placeholder="Stock Symbol"
              ng-model="newStock.company"
              bs-options="company as company.label for company in companies"
              bs-typeahead
              required>
          </div>
          <div class="form-group">
            <label for="stock-shares">Shares Owned</label>
            <input type="number"
              class="form-control"
              id="stock-shares"
              placeholder="# Shares Owned"
              ng-model="newStock.shares"
              required>
          </div>
        </div>
        <div class="modal-footer">
          <button type="submit"
            class="btn btn-success"
            ng-click="addStock()"
            ng-disabled="!stockForm.$valid">Add</button>
          <button type="button"
            class="btn btn-danger"
            ng-click="$hide()">Cancel</button>
        </div>
      </form>
    </div>
  </div>
</div>

编辑：添加关注列表服务

angular.module('stockDogApp')
  .service('WatchlistService', function () {
    var loadModel = function(){
      var model = {
      watchlists : localStorage['StockDog.watchlists'] ? JSON.parse(localStorage['StockDog.watchlists']) : [],
      nextId : localStorage['StockDog.nextId'] ? parseInt(localStorage['StockDog.nextId']) : 0
    };
    _.each(model.watchlists,function(watchlist){
      _.extend(watchlist,WatchlistModel);
      _.each(watchlist.stocks,function(stock){
        _.extend(stock,StockModel);
      });
    });
    return model;
  };

  var StockModel = {
    save: function(){
      var watchlist = findById(this.listId);
      watchlist.recalculate();
      saveModel;
    }
  };

  var WatchlistModel = {
    addStock: function(stock){
      var existingStock = _.find(this.stocks,function(s){
        return s.company.symbol === stock.company.symbol;
      });
      if (existingStock){
        existingStock.shares += stock.shares;
      }else{
        _.extend(stock,StockModel);
        this.stocks.push(stock);
      }
      this.recalculate();
      saveModel();
    },

原来Angular-Yeoman在app.js中自动生成一个控制器功能及其冲突的原因

  .when('/watchlist/:listId', {
    templateUrl: 'views/watchlist.html',
    controller: 'WatchlistCtrl',
    // controllerAs: 'watchlist'
  })

评论出控制器做了诀窍

AngularJS无法识别功能
