Question

我有两个范围函数，并声明了一个全局范围变量。我在一个函数中对全局变量进行了更改，但它没有反映在angularjs中的其他函数中。

该场景就像我在表格中有一个复选框，并编写了一个函数，如果选中该复选框，则值将被推送到$scope.selection=[];。

我有另一个删除按钮，它正在调用删除功能，删除操作将使用存储在数组中的值执行。但是当我在console.log()内部给出$scope.selectionlist = []; $scope.selectitem = function(itemselected){ if(itemselected.isChecked === true) { $scope.selectionlist.push(itemselected.xyz); } } $scope.deletememo = function(){ console.log("selection inside deletememo",$scope.selectionlist.length); }时，我得到的是空数组而不是修改过的数组。删除功能。请告诉我你的建议。

试试此代码。运行代码段以查看结果。

// Code goes here

var app = angular.module('myApp',[]);

app.controller('mainCntrl',function($scope){
  
  $scope.selectionlist = [];
  
  $scope.memo = [{'name': 'denny'},
                 {'name': 'john'},
                 {'name': 'joe'},
                 {'name': 'snowden'}
                 ];

  $scope.selectedItem = function(data){
    if(data.checkbox){
      $scope.selectionlist.push(data);
      console.log($scope.selectionlist);
      }
  else{
      var index = $scope.selectionlist.indexOf(data);
      $scope.selectionlist.splice(index, 1); 
      console.log($scope.selectionlist);
      }
    };

  $scope.deleteMemo = function(){
     console.log($scope.selectionlist);
   };
  
  });
