使用自动创建的名称保存范围变量并附加到范围

Question

在多步骤表单中，我有一个前一个，下一个指令，它获取当前步骤并将其保存在会话存储变量中。用户填写的步骤1模板上的所有信息都存储在$ scope.section1对象中。我想继续保存＆＃34; section2＆＃34;，＆＃34; section3＆＃34;在每个步骤上单击下一步。如何动态生成$ scope.section1，$ scope.section2？我想保留符号＆＃34; section1＆＃34;，＆＃34; section2＆＃34;等

控制器：

$sessionStorage[currindex] = $scope.section1;  

指令：

$scope.nextPage = function(){
           var currindex = $scope.getIndex();
          var nextindex = ++currindex;
         //storing in session    
        $sessionStorage[currindex] = $scope.section1;   
    }

Answer 1

使用[]代替.之类的内容

$scope.nextPage = function(){
       var currindex = $scope.getIndex();
      var nextindex = ++currindex;
     //storing in session    
    $sessionStorage[currindex] = $scope['section' + currindex];   
}

这就是你要找的东西吗？
