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
<body ng-controller="map_ctrl"> <table> <tbody> <tr ng-repeat="l in orderList"> <td><input type="radio" ng-click="select(l.id)" value="{{l.id}}" /></td> <td>{{l.time}}</td> </tr> </tbody> </table> <!-- paging datalist属性值(dataList)为要分页的原始数据--> <rj-date datalist="dataList"></rj-date> </body>
index.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){ $scope.orderList = orderList; }); });
指令模板 page.html
<div> <p> <span> 总记录数：<span ng-bind="page.nums"></span> 本页记录数：<span ng-bind="page.nowNums"></span> </span> <button ng-click="jumpPage(1,dataList)">首页</button> <button ng-click="jumpPage(page.now-1,dataList)">上一页</button> <span> <span ng-bind="page.now"></span>/ <span ng-bind="page.pageCount"></span> </span> <button ng-click="jumpPage(page.now+1,dataList)">下一页</button> <button ng-click="jumpPage(page.pageCount,dataList)">尾页</button> 到第 <input type="text" ng-model="page.jumpPage" value=""/> 页 <button ng-click="jumpPage(page.jumpPage,dataList)">确定</button> </p> </div>
指令定义page.js
app.directive('rjDate',function(){ return { restrict: 'EA', replace: false, scope : {dataList:'=datalist'},//设置scope.dataList与指令属性“datalist”值绑定，详情看指令scop作用域 templateUrl: 'pageDirective/template/page.html', link: function(scope,elem,attr){ var page={};//分页对象 scope.page=page; scope.page.onePageNums=10; //每页记录数 scope.page.nums=0; scope.page.now=1; scope.page.nowNums=0; scope.page.pageCount=1; scope.getPage=getPage; //设置获取页面的ng-click scope.page.orderList=[]; getPage(1,scope.dataList);//初始化获取第一页数据 scope.jumpPage=function(page,dataList){ if(!parseInt(page)){ return null; } getPage(page,dataList); } function getPage(pageNow,dataList){//获取指定的页面 scope.page.nums=dataList.length; //设置总记录数 scope.page.now=pageNow;//设置当前是第几页 pagination();//设置当前有多少页面 生成一个页面数组 scope.page.orderList=getOnePage(dataList);//获取一页的数据 scope.$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 } function getOnePage(arr){//获取一页的数据 if(arr==null){ return null; } var newarr=new Array(); if(scope.page.now<1){ scope.page.now=1; } if(scope.page.now>scope.page.pageCount){ scope.page.now=scope.page.pageCount; } scope.page.nowNums=scope.page.onePageNums; var pagenow=scope.page.now; var begin=(pagenow-1)*scope.page.onePageNums; var end=begin+scope.page.onePageNums; var lens=scope.page.nums; if(end>lens){ end=lens; scope.page.nowNums=lens-begin; } for(begin;begin<end;begin++){ newarr.push(arr[begin]); } return newarr; } function pagination(){//设置当前有多少页面 生成一个页面数组 if(scope.page.nums<=scope.page.onePageNums){ scope.page.pageCount=1; }else{ if(scope.page.nums%scope.page.onePageNums==0){ scope.page.pageCount=scope.page.nums/scope.page.onePageNums; }else{ scope.page.pageCount=parseInt(scope.page.nums/scope.page.onePageNums)+1; } } } } } });
效果如图所示：
