页面HTML代码:
<!-- paging --> <ul class="pagination" style="margin: 0px;" > <li ng-class="{true:'disabled'}[p_current==1]"><a href="javascript:void(0);" ng-click="p_index()">首页</a></li> <li ng-repeat="page in pages" ng-class="{true:'active'}[p_current==page]"><a href="javascript:void(0);" ng-click="load_page(page)">{{ page }}</a></li> <li ng-class="{true:'disabled'}[p_current==p_all_page]"><a href="javascript:void(0);" ng-click="p_last()">尾页</a></li> </ul>
<span style="vertical-align: 12px;"> 共:{{count}} 条</span>
Js代码:
var app = angular.module("myApp",[]);
app.controller("map_ctrl",function($scope,$http,$location){ //配置 $scope.count = 0; $scope.p_pernum = 10; //变量 $scope.p_current = 1; $scope.p_all_page =0; $scope.pages = []; //初始化第一页 _get($scope.p_current,$scope.p_pernum,function(){ alert("我是第一次加载"); }); //获取数据 var _get = function(page,size,callback){ $http.get("xxx.html?status=0&page="+page+"&size="+size).success(function(res){ if(res&&res.status==1){ $scope.count=res.count; $scope.list=res.list; $scope.p_current = page; $scope.p_all_page =Math.ceil($scope.count/$scope.p_pernum); reloadPno(); callback(); }else{ alert("加载失败"); } }); } //单选按钮选中 $scope.select= function(id){ alert(id); } //首页 $scope.p_index = function(){ $scope.load_page(1); } //尾页 $scope.p_last = function(){ $scope.load_page($scope.p_all_page); } //加载某一页 $scope.load_page = function(page){ _get(page,$scope.p_pernum,function(){ }); }; //初始化页码 var reloadPno = function(){ $scope.pages=calculateIndexes($scope.p_current,$scope.p_all_page,8); }; //分页算法 var calculateIndexes = function (current, length, displayLength) { var indexes = []; var start = Math.round(current - displayLength / 2); var end = Math.round(current + displayLength / 2); if (start <= 1) { start = 1; end = start + displayLength - 1; if (end >= length - 1) { end = length - 1; } } if (end >= length - 1) { end = length; start = end - displayLength + 1; if (start <= 1) { start = 1; } } for (var i = start; i <= end; i++) { indexes.push(i); } return indexes; };
});
分页算法:
current :当前页码,length:总页码,displayLength:显示长度 @return array[1,2,3,4,5,6,7,8]
var calculateIndexes = function (current, length, displayLength) { var indexes = []; var start = Math.round(current - displayLength / 2); var end = Math.round(current + displayLength / 2); if (start <= 1) { start = 1; end = start + displayLength - 1; if (end >= length - 1) { end = length - 1; } } if (end >= length - 1) { end = length ; start = end - displayLength + 1; if (start <= 1) { start = 1; } } for (var i = start; i <= end; i++) { indexes.push(i); } return indexes; };
