常用的Underscore取代for循环

1._.filer

// console.log(result)
// $scope.number = result.length;
var result = _.filter(event, function (num) {

2._.sotBy
// var temp;
// for (var i = result.length - 1; i > 0; --i) {

// result[j + 1] = temp;

// }
// $scope.lists = result;
var result = _.sortBy(result, function (num) {

3._.map
for (i = 0; i < list.length; i++) {
if (list[i].activity == (localStorage.getItem("nowActivity"))) {
new_list.push(list[i])
}
}
// var new_list = _.map(list,function(num){return num.activity == now_activity})
// console.log(list.length + JSON.stringify(new_list))
