angular分页指令操作

目前的多个项目中都用到分页这个功能，为了提高可复用性，我特地分离出来写了个分页的指令。直接贴代码，详情如下：

index.html

rush:xhtml;">

index.js

rush:js;"> var app = angular.module("doSBill",[]);

app.controller("map_ctrl",function($scope,$http,$location,$timeout){
// 原始数据
$scope.dataList=[
{'time':1},{'time':2},{'time':3},{'time':4},{'time':5},{'time':6},{'time':7},{'time':8},{'time':9},{'time':10},{'time':11},{'time':12},{'time':13},{'time':14},{'time':15},{'time':16},{'time':17},{'time':18},{'time':19},{'time':20},{'time':21},{'time':22},{'time':23},{'time':24},{'time':25},{'time':26},{'time':27},{'time':28},{'time':29},{'time':30},{'time':31}
];
//$on：监听或接收数据；此处用于监听分页指令，修改的列表视图数据
$scope.$on("orderList",function(e,orderList){
$scope.orderList = orderList;
});

});

指令模板 page.html

rush:xhtml;">

总记录数：本页记录数：NowNums" ng-bind="page.NowNums"> NowPage" ng-bind="page.Now">/

指令定义page.js

rush:js;"> app.directive('rjDate',function(){ return { restrict: 'EA',replace: false,scope : {dataList:'=datalist'},//设置scope.dataList与指令属性“datalist”值绑定，详情看指令scop作用域 templateUrl: 'pageDirective/template/page.html',link: function(scope,elem,attr){
