$scope.todos = [ {text:'learn',done:true},{text:'build',done:false},{text:'watch',{text:'destroy',{text:'rebuild',done:false}]; $scope.remaining = function() { var count = 0; angular.forEach($scope.todos,function(todo,i) { todo.text = 'want2learn'; todo.text[i+1] = todo.text; });
是否有可能ForEach函数访问/设置对象的上一个/下一个索引数组值,可能吗?
解决方法
是,
$scope.todos[i+1].text = todo.text;
你想要防止索引超过数组的末尾:
if(i < $scope.todos.length - 1) { $scope.todos[i+1].text = todo.text; }
