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
1 <body id="sBill" ng-controller="map_ctrl"> 2 <table class="table table-striped" style="margin: 0px;border:1px solid #ccc;width:800px;min-height:200px;"> 3 <tbody> 4 <tr ng-repeat="l in orderList"> 5 <td><input type="radio" name="id" ng-click="select(l.id)" value="{{l.id}}" /></td> 6 <td>{{l.time}}</td> 7 </tr> 8 </tbody> 9 </table> 10 <!-- paging datalist属性值(dataList)为要分页的原始数据--> 11 <rj-date datalist="dataList"></rj-date> 12 13 </body>index.js
1 var app = angular.module("doSBill",[]); 2 3 app.controller("map_ctrl",function($scope,$http,$location,$timeout){ 4 // 原始数据 5 $scope.dataList=[ 6 {'time':1},{'time':2},{'time':3},{'time':4},{'time':5},{'time':6},{'time':7},{'time':8},{'time':9},{'time':10}, 7 {'time':11},{'time':12},{'time':13},{'time':14},{'time':15},{'time':16},{'time':17},{'time':18},{'time':19},{'time':20}, 8 {'time':21},{'time':22},{'time':23},{'time':24},{'time':25},{'time':26},{'time':27},{'time':28},{'time':29},{'time':30}, 9 {'time':31}10 ];11 //$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12 $scope.$on("orderList", function(e, orderList){13 $scope.orderList = orderList;14 });15 16 });
指令模板 page.html
1 <div> 2 <p> 3 <span> 4 总记录数：<span class="rjAllNums" ng-bind="page.nums"></span> 5 本页记录数：<span class="rjNowNums" ng-bind="page.nowNums"></span> 6 </span> 7 <button class="rjFirtPage" ng-click="jumpPage(1,dataList)">首页</button> 8 <button class="rjPrePage" ng-click="jumpPage(page.now-1,dataList)">上一页</button> 9 <span>10 <span class="rjNowPage" ng-bind="page.now"></span>/11 <span class="rjAllPage" ng-bind="page.pageCount"></span>12 </span>13 <button class="rjNextPage" ng-click="jumpPage(page.now+1,dataList)">下一页</button>14 <button class="rjLastPage" ng-click="jumpPage(page.pageCount,dataList)">尾页</button>15 到第 16 <input class="rjJumpInput" type="text" ng-model="page.jumpPage" name="rjPageName" value=""/>17 页18 <button class="rjJumpBtn" ng-click="jumpPage(page.jumpPage,dataList)">确定</button>19 </p>20 21 </div>
指令定义page.js
1 app.directive('rjDate',function(){ 2 return { 3 restrict: 'EA', 4 replace: false, 5 scope : {dataList:'=datalist'},//设置scope.dataList与指令属性“datalist”值绑定，详情看指令scop作用域 6 templateUrl: 'pageDirective/template/page.html', 7 link: function(scope,elem,attr){ 8 9 var page={};//分页对象10 scope.page=page;11 scope.page.onePageNums=10; //每页记录数12 scope.page.nums=0;13 scope.page.now=1;14 scope.page.nowNums=0;15 scope.page.pageCount=1;16 scope.getPage=getPage; //设置获取页面的ng-click17 scope.page.orderList=[];18 19 getPage(1,scope.dataList);//初始化获取第一页数据20 21 scope.jumpPage=function(page,dataList){ 22 if(!parseInt(page)){23 return null;24 }25 getPage(page,dataList);26 }27 function getPage(pageNow,dataList){//获取指定的页面 28 scope.page.nums=dataList.length; //设置总记录数29 scope.page.now=pageNow;//设置当前是第几页30 pagination();//设置当前有多少页面 生成一个页面数组31 scope.page.orderList=getOnePage(dataList);//获取一页的数据32 scope.$emit("orderList", scope.page.orderList);//$emit：子传父，传递event与data；此处用于给父controller传递数据orderList 33 }34 35 function getOnePage(arr){//获取一页的数据36 if(arr==null){ 37 return null;38 } 39 var newarr=new Array();40 if(scope.page.now<1){41 scope.page.now=1;42 }43 if(scope.page.now>scope.page.pageCount){44 scope.page.now=scope.page.pageCount;45 }46 scope.page.nowNums=scope.page.onePageNums;47 var pagenow=scope.page.now; 48 49 var begin=(pagenow-1)*scope.page.onePageNums; 50 var end=begin+scope.page.onePageNums;51 var lens=scope.page.nums;52 53 if(end>lens){54 end=lens;55 scope.page.nowNums=lens-begin;56 }57 58 for(begin;begin<end;begin++){59 newarr.push(arr[begin]);60 }61 return newarr;62 }63 function pagination(){//设置当前有多少页面 生成一个页面数组64 if(scope.page.nums<=scope.page.onePageNums){65 scope.page.pageCount=1;66 }else{67 if(scope.page.nums%scope.page.onePageNums==0){68 scope.page.pageCount=scope.page.nums/scope.page.onePageNums;69 }else{70 scope.page.pageCount=parseInt(scope.page.nums/scope.page.onePageNums)+1;71 }72 }73 }74 75 }76 }77 }); 效果如图所示：
