$scope.allNum = $scope.listData.length;
$scope.allPage = Math.ceil($scope.allNum / 10);
console.log($scope.listData);

//分页
$scope.defaultPage = 1;
$scope.nowArr = [];
for(var i=0; i<($scope.allNum < 10?$scope.allNum:10);i++){
$scope.nowArr.push($scope.listData[i]);
}

//下一页
$scope.pageDown = function(){
$scope.nowArr = [];
if($scope.defaultPage<$scope.allPage){
$scope.defaultPage++;
}
for(var i=($scope.defaultPage-1)*10;i<($scope.defaultPage*10);i++){
if(i<=$scope.allNum-1){
$scope.nowArr.push($scope.listData[i]);

//上一页
$scope.pageUp = function(){
$scope.nowArr = [];
if($scope.defaultPage>1){
$scope.defaultPage--;
