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
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" style="margin: 0px;border:1px solid #ccc;width:800px;min-height:200px;">
<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：
