angularjs实现的前端分页控件示例

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...

}

}

});
