angularjs实现的前端分页控件

前言：之前写个一个jQuery的分页显示插件，http://blog.csdn.net/peakchen_90/article/details/52187175，存在许多的bug，现在由于业务需要，学习的一点angularjs，重新用angularjs实现了这个分页插件

实现效果图：

（效果图是加上了bootstrap的css文件）

这里写图片描述

用法：

angular-pagination.js代码：

/** * angularjs分页控件 * Created by CHEN on 2016/11/1. */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) $scope.option.curr = 1;            if (!$scope.option.all || isNaN($scope.option.all) || $scope.option.all < 1) $scope.option.all = 1;            if ($scope.option.curr > $scope.option.all) $scope.option.curr = $scope.option.all;            if (!$scope.option.count || isNaN($scope.option.count) || $scope.option.count < 1) $scope.option.count = 10;            //得到显示页数的数组            $scope.page = getRange($scope.option.curr, $scope.option.all, $scope.option.count);            //绑定点击事件            $scope.pageClick = function (page) {                if (page == '«') {                    page = parseInt($scope.option.curr) - 1;                } else if (page == '»') {                    page = parseInt($scope.option.curr) + 1;                }                if (page < 1) page = 1;                else if (page > $scope.option.all) page = $scope.option.all;                //点击相同的页数 不执行点击事件                if (page == $scope.option.curr) return;                if ($scope.option.click && typeof $scope.option.click === 'function') {                    $scope.option.click(page);                    $scope.option.curr = page;                    $scope.page = getRange($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;                    if (from <= 0) {                        from = 1;                    }                }                var range = [];                for (var i = from; i <= to; i++) {                    range.push(i);                }                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...        }    }});
