angular 搜索记录保留

  #方法1：   点击后退到home后，再点击搜索， locationChangeStart 事件会多次触发。
  # $scope.keyword =  $location.search().search
  # $scope.search = ()->
  #   return if $scope.isSearching
  #   return unless $scope.sitetype and $scope.keyword
  #   $location.search({search: $scope.keyword})

  #   if $scope.sitetype == 'site'
  #     $scope.doSearch()
  #   else
  #     $scope.connectSocket($scope.doSearch)

  # #有关键词的时候，执行搜索任务
  # if $scope.keyword
  #   $scope.search()

  # $rootScope.$on '$locationChangeStart', (e, next, current)->
  #   console.log 'locationChangeStart...'
  #   $scope.keyword =  $location.search().search
  #   $scope.search()

     # 方法2    路由：  url: '/search/*path'
  $scope.keyword = $location.path().slice(8)
  $scope.setPath = (keyword)->
    if !keyword
      keyword = $scope.keyword
    $location.path('/search/'+keyword)
　　　#搜索
 　　 if $scope.keyword
