如何在Facebook分享按鈕中使用角度js傳遞URL

Question

這是html共享按鈕，點擊時共享data-href中給出的url。
問題：我想根據條件使用角度js傳遞URL。 我已經在$ scope.sd中存儲了url如何在data-href中使用它。

我試過把data-href =“sd”但是它沒有用。

<div id="fb" class="fb-share-button" data-href="http://sample-env.yqk6qkszsb.us-west-2.elasticbeanstalk.com/static/polls/img/icon.png" data-layout="button_count" data-size="large" data-mobile-iframe="true"><a class="fb-xfbml-parse-ignore" target="_blank" href="https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2Fplugins%2F&amp;src=sdkpreparse">Share</a></div>

app.js

var app = angular.module('myApp',[]);
   app.controller('ctrl',function($scope){
      $scope.wish=["Birthday","Makar Shankranti","Valentine Day","Holi","Friendship Day"];
      $scope.show=true;
      $scope.isVisible=false;
      $scope.sd='http://nishantsingh.tk'; // I want to pass this url

      $scope.create = function(name,choice){
            $scope.user=name;
            if(!$scope.user){return $scope.errmsg="Please enter your name";}
            if(!$scope.choice){return $scope.errmsg="Please choose your wish";}
            $scope.show=false;
            $scope.isVisible = true;
            $scope.day=choice;
            if(choice=='Birthday'){$scope.bg={background : 'url(../../static/polls/img/birthday.gif)'}}
            else if (choice=='Makar Shankranti'){$scope.bg={background : 'url(../../static/polls/img/makar.gif)'}}
            else if (choice=='Valentine Day'){$scope.bg={background : 'url(../../static/polls/img/valentine.gif)'}}
            else if (choice=='Friendship Day'){$scope.bg={background : 'url(../../static/polls/img/friendship.gif)'}}
            else if (choice=='Holi'){$scope.bg={background : 'url(../../static/polls/img/holi.gif)'}}
      };
      $scope.anCreate=function(anotherName,choice){
          if(!$scope.anotherName){return $scope.msg="Please enter your name";}
          $scope.user=anotherName;
      };
    });

您可以嘗試使用data-href="{{sd}}"

<div id="fb" class="fb-share-button" data-href="{{sd}}" data-layout="button_count" data-size="large" data-mobile-iframe="true"><a class="fb-xfbml-parse-ignore" target="_blank" href="https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2Fplugins%2F&amp;src=sdkpreparse">Share</a></div>
