$scope.todos = [
{text:'learn', done:true},
{text:'build', done:false},
{text:'watch', done:false},
{text:'destroy', done:false},
{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?

是,
$scope.todos[i+1].text = todo.text;
你想要防止索引超过数组末尾:
if(i < $scope.todos.length - 1) {
$scope.todos[i+1].text = todo.text;
}
