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...
}
}
});
