angularjs实现的前端分页控件示例

2017-02-17 15:07:39 AngularJS

本篇文章主要介绍了angularjs实现的前端分页控件示例，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
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

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...
    }
  }
});
