$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[i+1] = todo.text;
});
ForEach 函数是否可以访问/设置对象的上一个/下一个索引数组值,可能吗?
