Javascript Angularjs:-如何借助指令调用控制器动作

嗨，我是angularjs的新手

我想实现一个代码，当我点击一个按钮时，我应该能够进行api调用并在HTML中显示数据

现在我已经实现了一个指令并生成了HTML，但是当我单击favicon或reminder时，它不起作用

以下是在名为usercontrollerIt的控制器中实现的。它还有许多其他功能。但是我不太确定如何调用该控制器，仅针对favicon

以下是我写的指令：-

'use strict';
var pageno=1;

function MainCtrl($scope) {
    $scope.count = 0;
}

//Directive that returns an element which adds buttons on click which show an alert on click.Here we can put
woi.directive("yes",['userAPI','$rootScope', function(userAPI,$rootScope){

    return {
        restrict: "E",
        template: "<button ng-click='str()' addbuttons>please click for Top Rated</button>"



//Directive for adding buttons on click that show an alert on click
woi.directive("addbuttons",['$rootScope','userAPI','$compile','$filter', function($rootScope,userAPI,$compile,$filter,){
    return function(scope, element, attrs){
        element.bind("click", function(){
         //   var pageno=1;
            scope.count++;
            var pageno=1;
            pageno++;
            scope.pageNo=pageno;
            //var abc= scope.loadRated(pageno);
            userAPI.topRated({userid: $rootScope.getUser().userid,pageno:pageno}, function (r, $scope, div){
                if(!$rootScope.device.isMobile && !$rootScope.device.isTablet && !$rootScope.device.isTouch ) {
                    var topRatedList = r.gettopratedhomepage.topratedprogrammelist;
                    console.log(r)


                    var str='';
                    if(r !=null && r.gettopratedhomepage!=null && r.gettopratedhomepage.topratedprogrammelist!=null)
                        if(r.gettopratedhomepage.topratedprogrammelist.length>0){

                            for(var i=0;i<topRatedList.length;i++)
                            {
                                // str+="topRatedList[i].actualname";

                                var programNameEncode=$filter('encodeUrl')(topRatedList[i].programmename);  // | encodeUrl;    topRatedList[i].programmename;
                                var program=topRatedList[i].programmename;
                                var channelId=topRatedList[i].channelid;
                                var programId=topRatedList[i].programmeid;
                                var channel=topRatedList[i].channeldisplayname;
                                var channelNameEncode=$filter('encodeUrl')(topRatedList[i].channeldisplayname)       //| encodeUrl;
                                //   var startTime=topRatedList[i].starttime;
                                var favourite=topRatedList[i].isfavorite;
                                var reminder=topRatedList[i].isreminder;
                                var watchlist=topRatedList[i].iswatchlist;
                                var duration=topRatedList[i].duration;
                                var imageFile=topRatedList[i].imagefilepath;
                                var startTime = $filter('featuredVideoTime')(topRatedList[i].starttime) ;             // featured video time
                                var duration= topRatedList[i].duration;
                                var isReco=topRatedList[i].isrecommended;         // This is for reco

                                var genre=topRatedList[i].channelgenre;

                    angular.element(document.getElementById('space-for-buttons')).append($compile(str)(scope));



                    // The above code is required to append data into the division(loadrated)..

                }
            });

        });
    };
}]);

我已经创建了一个字符串，正在为要生成的程序创建HTML

有人能帮我一下吗？谢谢

如果您想在显示特定消息后单击按钮时从指令调用控制器的操作，您可以将操作和消息设置为指令中的参数。试试这个

'use strict';

angular.module('directives')
    .directive("MyButton", function(){
        return{
            restrict: "E",
            replace: true,
            link :function(scope, element, atts){
                    var buttonText = "<button class='btn btn-primary'>click</button>";
                    element.html(buttonText);
                    element.on("click", function(){
                        var result = confirm(atts.message);
                        if(result)
                        {
                            scope.$apply(atts.action);
                        }
                    });
            }
        }
    });

然后你可以这样设置指令中的参数

<my-button message="Are you sure?" action="delete"></my-button>

@safaa elgendi..谢谢你提供的信息..但是我想在参数的帮助下进行api调用，并在单击按钮时得到结果。我们可以实现这个吗
