Angular js：如何將數據附加到HTML

Question

嗨，我正在用angularjs實現一個網站。

我面臨一個問題。 我有一個小部件，一次顯示10條記錄，當我單擊“查看更多”按鈕時，它會根據頁碼獲取下10條記錄。

我已經實現了一個按鈕

`<button ng-click="loadYourRecs(true)">click here for Recs</button>

現在單擊按鈕，我正在調用控制器並獲取數據，如下所示：-

 $scope.loadRated = function(flag){

        if(flag==true)
        {
            $rootScope.TopPge +=1;
        }
        // call api
        var $ratedSpinner = $('.rated-spin');
        loading('show',{element: $ratedSpinner});
        userAPI.topRated({userid: $rootScope.getUser().userid, pageno:$rootScope.TopPge}, function(r){

            var loading = $filter('loading');
            loading('hide', { element: $('#loadIndicator2') });

            $scope.ratedLoaded = true;

            loading('hide',{element: $ratedSpinner});
            $scope.programs.rated = r.gettopratedhomepage.topratedprogrammelist;

            var _gaq = _gaq || [];
            _gaq.push(['_setAccount', 'UA-398742-8']);
            _gaq.push(['_trackEvent','WOITopRated','TopRated','Load']);

            for(i=0; i<$scope.programs.rated.length; i++){
                //abbreviates the month
                $scope.programs.rated[i].timestring = abbrMonth($scope.programs.rated[i].timestring) ;
            }
            // called with timeout for dom creation
            setTimeout(function(){
                if(openTabIndex === 3) {
                    showTab(openTabIndex);
                }
                showMoreOnTab(3);
            }, 5);
        });
    };

`我正在通過api調用獲取數據。

HTML代碼如下：

<div class='channel-tabs hidden-phone' ng-controller='Home_ProgramsTabController' ng-init='init()'>
<div class='tab clearfix' ng-show="currentActiveTab == 'rated'">

          <div class='item' ng-repeat='p in programs.rated' home-tab-item watchable="p" ></div>

        <div id="space-for-buttons">
          <div class = 'rated-spin' ng-show = 'programs.rated == 0 && ratedLoaded == false'> </div>
          <div ng-show="programs.rated == 0  && ratedLoaded == true" class="noResultsBlock">No Results for Rated.</div>
          <div class='clearfix'></div>
        </div>

          <div ng-controller="Home_ProgramsTabController" ng-app="woi">

            <button ng-click="loadRated(true)">click here for Rated</button>

          </div>

        </div>

現在我面臨的問題是，獲取的數據將替換目標div中的舊內容。 我要附加它。

Answer 1

您需要將數據追加到數組。

        loading('hide',{element: $ratedSpinner});
        var newRated = r.gettopratedhomepage.topratedprogrammelist;

        var _gaq = _gaq || [];
        _gaq.push(['_setAccount', 'UA-398742-8']);
        _gaq.push(['_trackEvent','WOITopRated','TopRated','Load']);

        for(i=0; i<newRated.length; i++){
            //abbreviates the month
            newRated[i].timestring = abbrMonth(newRated.timestring) ;
        }

        //append
        $scope.programs.rated = ($scope.programs.rated||[]).concat(newRated);

要么

$scope.programs.rated.push.apply($scope.programs.rated, newRated); 

Answer 2

userAPI.topRated({userid: $rootScope.getUser().userid, pageno:$rootScope.TopPge}, function(r){

        var loading = $filter('loading');
        loading('hide', { element: $('#loadIndicator2') });

        $scope.ratedLoaded = true;

        loading('hide',{element: $ratedSpinner});

        var _gaq = _gaq || [];
        _gaq.push(['_setAccount', 'UA-398742-8']);
        _gaq.push(['_trackEvent','WOITopRated','TopRated','Load']);

        for(i=0; i<r.gettopratedhomepage.topratedprogrammelist; i++){
            //abbreviates the month
            var el = r.gettopratedhomepage.topratedprogrammelist[i];
            el.timestring = abbrMonth(el.timestring) ;
           $scope.programs.rated.push(el);
        }
        // called with timeout for dom creation
        setTimeout(function(){
            if(openTabIndex === 3) {
                showTab(openTabIndex);
            }
            showMoreOnTab(3);
        }, 5);
    });
