前言:之前写个一个jQuery的分页显示插件,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)

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:;" rel="external nofollow" >{{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...    }  }});
