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;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 $scope.orderList = orderList; 14 }); 15 16 });
指令模板 page.html
1 <div> 2 <p> 3 <span> 4 总记录数：<span class="rjAllNums" ng-bind="page.nums"></span> 5 本页记录数：<span class="rjNowNums" ng-bind="page.nowNums"></span> 6 </span> 7 <button class="rjFirtPage" ng-click="jumpPage(1,dataList)">首页</button> 8 <button class="rjPrePage" ng-click="jumpPage(page.now-1,dataList)">上一页</button> 9 <span> 10 <span class="rjNowPage" ng-bind="page.now"></span>/ 11 <span class="rjAllPage" ng-bind="page.pageCount"></span> 12 </span> 13 <button class="rjNextPage" ng-click="jumpPage(page.now+1,dataList)">下一页</button> 14 <button class="rjLastPage" ng-click="jumpPage(page.pageCount,dataList)">尾页</button> 15 到第 16 <input class="rjJumpInput" type="text" ng-model="page.jumpPage" name="rjPageName" value=""/> 17 页 18 <button class="rjJumpBtn" ng-click="jumpPage(page.jumpPage,dataList)">确定</button> 19 </p> 20 21 </div>
指令定义page.js
1 app.directive('rjDate',function(){ 2 return { 3 restrict: 'EA', 4 replace: false, 5 scope : {dataList:'=datalist'},//设置scope.dataList与指令属性“datalist”值绑定，详情看指令scop作用域 6 templateUrl: 'pageDirective/template/page.html', 7 link: function(scope,elem,attr){ 8 9 var page={};//分页对象 10 scope.page=page; 11 scope.page.onePageNums=10; //每页记录数 12 scope.page.nums=0; 13 scope.page.now=1; 14 scope.page.nowNums=0; 15 scope.page.pageCount=1; 16 scope.getPage=getPage; //设置获取页面的ng-click 17 scope.page.orderList=[]; 18 19 getPage(1,scope.dataList);//初始化获取第一页数据 20 21 scope.jumpPage=function(page,dataList){ 22 if(!parseInt(page)){ 23 return null; 24 } 25 getPage(page,dataList); 26 } 27 function getPage(pageNow,dataList){//获取指定的页面 28 scope.page.nums=dataList.length; //设置总记录数 29 scope.page.now=pageNow;//设置当前是第几页 30 pagination();//设置当前有多少页面 生成一个页面数组 31 scope.page.orderList=getOnePage(dataList);//获取一页的数据 32 scope.$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：
