angular-pagination.js代码:

angular.module('myModule', []).directive('myPagination', function () {
    return {
        restrict: 'EA',
        replace: true,
        scope: {
            option: '=pageOption'
        },
        template: '<ul class="pagination">' +
        '<li ng-click="pageClick(p)" ng-repeat="p in page" class="{{option.curr==p?\'active\':\'\'}}">' +
        '<a href="javascript:;">{{p}}</a>' +
        '</li>' +
        '</ul>',
        link: function ($scope) {
            //容错处理
            if (!$scope.option.curr || isNaN($scope.option.curr) || $scope.option.curr < 1) $scope.option.curr = 1;

            //得到显示页数的数组
            $scope.page = getRange($scope.option.curr, $scope.option.all, $scope.option.count);

                    $scope.page = getRange($scope.option.curr, $scope.option.all, $scope.option.count);
                }
            };

            //返回页数范围(用来遍历)
            function getRange(curr, all, count) {
                //计算显示的页数
                curr = parseInt(curr);
                all = parseInt(all);
                count = parseInt(count);
                var from = curr - parseInt(count / 2);
                var to = curr + parseInt(count / 2) + (count % 2) - 1;
                //显示的页数容处理
                if (from <= 0) {
                    from = 1;
                    to = from + count - 1;
                    if (to > all) {
                        to = all;
                    }
                }
                if (to > all) {
                    to = all;
                    from = to - count + 1;

                }
                range.push('»');
                range.unshift('«');
                return range;
            }

        }
    }
});

index.html代码:

<!doctype html>
<html ng-app="app">
<head>
    <meta charset="UTF-8">
    <title>Angularjs分页控件</title>
    <script src="angular.min.js"></script>  <!-- 引入angularjs文件,而且是1.x版本的 -->
    <script src="angular-pagination.js"></script> <!-- 引入angularjs分页控件 -->
    <script src="app.js"></script> <!-- 引入app.js -->
</head>
<body>

<!-- 控制器 -->
<div ng-controller="myCtrl">

    <!-- 分页控件指令 ,可以是元素 或者 属性 -->
    <my-pagination page-option="option"></my-pagination>

</div>

</body>
</html>

app.js代码:

//引入 'myModele' 模块
var app = angular.module('app', ['myModule']);

app.contriller('myCtrl', function($scope){

    //设置分页的参数
    $scope.option = {
        curr: 1,  //当前页数
        all: 20,  //总页数
        count: 10,  //最多显示的页数,默认为10

        //点击页数的回调函数,参数page为点击的页数
        click: function (page) {
            console.log(page);
            //这里可以写跳转到某个页面等...
        }
    }
});
