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 id="sBill" ng-controller="map_ctrl">
<table class="table table-striped" >
<tbody>
<tr ng-repeat="l in orderList">
<td><input type="radio" name="id" 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){
$scope.orderList = orderList;
});
});
指令模板 page.html
<div>
<p>
<span>
总记录数：<span class="rjAllNums" ng-bind="page.nums"></span>
本页记录数：<span class="rjNowNums" ng-bind="page.nowNums"></span>
</span>
<button class="rjFirtPage" ng-click="jumpPage(1,dataList)">首页</button>
<button class="rjPrePage" ng-click="jumpPage(page.now-1,dataList)">上一页</button>
<span>
<span class="rjNowPage" ng-bind="page.now"></span>/
<span class="rjAllPage" ng-bind="page.pageCount"></span>
</span>
<button class="rjNextPage" ng-click="jumpPage(page.now+1,dataList)">下一页</button>
<button class="rjLastPage" ng-click="jumpPage(page.pageCount,dataList)">尾页</button>
到第
<input class="rjJumpInput" type="text" ng-model="page.jumpPage" name="rjPageName" value=""/>
页
<button class="rjJumpBtn" ng-click="jumpPage(page.jumpPage,dataList)">确定</button>
</p>
</div>
指令定义page.js
app.directive('rjDate',function(){
return {
restrict: 'EA',
replace: false,
scope : {dataList:'=datalist'},//设置scope.dataList与指令属性“datalist”值绑定，详情看指令scop作用域
templateUrl: 'pageDirective/template/page.html',
link: function(scope,elem,attr){
var page={};//分页对象
scope.page=page;
scope.page.onePageNums=10; //每页记录数
scope.page.nums=0;
scope.page.now=1;
scope.page.nowNums=0;
scope.page.pageCount=1;
scope.getPage=getPage; //设置获取页面的ng-click
scope.page.orderList=[];
getPage(1,scope.dataList);//初始化获取第一页数据
scope.jumpPage=function(page,dataList){
if(!parseInt(page)){
return null;
}
getPage(page,dataList);
}
function getPage(pageNow,dataList){//获取指定的页面
scope.page.nums=dataList.length; //设置总记录数
scope.page.now=pageNow;//设置当前是第几页
pagination();//设置当前有多少页面 生成一个页面数组
scope.page.orderList=getOnePage(dataList);//获取一页的数据
scope.$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：
