Angular.js+Bootstrap实现表格分页

最近一直学习Angular.js,在学习过程中也练习了很多的Demo,这里先贴一下表格+分页。

先上图看看最终结果:

Angular.js+Bootstrap实现表格分页

不得不说Angular.js代码风格很受人欢迎,几十行代码清晰简洁的实现了上面的功能。

首先表格的数据源来自于,Server.js 点击下载。通过get取数后分页显示。

1.表格是通过ng-repeat来展示的,代码如下:

<table class="table table-bordered">
<tr>
<th>index</th>
<th ng-repeat="(x,y) in items[0]">{{ x }}</th>
</tr>
<tr ng-repeat="x in items">
<td>{{ $index + 1 }}</td>
<td ng-bind="x.Name"></td>
<td ng-bind="x.City"></td>
<td ng-bind="x.Country"></td>
</tr>
</table>

$index是repeat的默认参数。表格的列头是通过数据源(json)的第一行循环取的key值。当然要是Bootstrap要指定table的Class是table table-bordered。

2.分页是也是用ng-repeat,不得不说ng-repeat是常用指令。分页代码如下:

<nav>
<ul class="pagination">
<li>
<a ng-click="Previous()">
<span>上一页</span>
</a>
</li>
<li ng-repeat="page in pageList" ng-class="{active: isActivePage(page)}" >
<a ng-click="selectPage(page)" >{{ page }}</a>
</li>
<li>
<a ng-click="Next()">
<span>下一页</span>
</a>
</li>
</ul>
</nav>

这里用了ng-click事件指令。还用到ng-class指令

ng-class="{active: isActivePage(page)}"

上面的代码是为了分页选中的样式。

这个表格加分页是假分页,从后端取一次数据,通过不同的分页显示json的筛选数据。

具体代码+注释:

<!-- 新 Bootstrap 核心 CSS 文件 -->
<link rel="stylesheet" href="http://apps.bdimg.com/libs/bootstrap/3.3.4/css/bootstrap.min.css">
<style>
#divMain {
width: 500px;
margin: 0 auto;
margin-top: 100px;
}
nav {
position: relative;
width:100%;
height: 50px;
}
.pagination {
right: 0px;
position: absolute;
top: -30px;
}
nav li {
cursor: pointer;
}
</style>
<div id="divMain" ng-app="myApp" ng-controller="myCtrl">
<table class="table table-bordered">
<tr>
<th>index</th>
<th ng-repeat="(x,y) in items[0]">{{ x }}</th>
</tr>
<tr ng-repeat="x in items">
<td>{{ $index + 1 }}</td>
<td ng-bind="x.Name"></td>
<td ng-bind="x.City"></td>
<td ng-bind="x.Country"></td>
</tr>
</table>
<nav>
<ul class="pagination">
<li>
<a ng-click="Previous()">
<span>上一页</span>
</a>
</li>
<li ng-repeat="page in pageList" ng-class="{active: isActivePage(page)}" >
<a ng-click="selectPage(page)" >{{ page }}</a>
</li>
<li>
<a ng-click="Next()">
<span>下一页</span>
</a>
</li>
</ul>
</nav>
</div>
<script src="http://apps.bdimg.com/libs/angular.js/1.5.0-beta.0/angular.js"></script>
<script type="text/javascript">
var app = angular.module("myApp", []);
app.controller("myCtrl", function ($scope, $http) {
$http.get("Service.js").then(function (response) {
//数据源
$scope.data = response.data.records;
//分页总数
$scope.pageSize = 5;
$scope.pages = Math.ceil($scope.data.length / $scope.pageSize); //分页数
$scope.newPages = $scope.pages > 5 ? 5 : $scope.pages;
$scope.pageList = [];
$scope.selPage = 1;
//设置表格数据源(分页)
$scope.setData = function () {
$scope.items = $scope.data.slice(($scope.pageSize * ($scope.selPage - 1)), ($scope.selPage * $scope.pageSize));//通过当前页数筛选出表格当前显示数据
}
$scope.items = $scope.data.slice(0, $scope.pageSize);
//分页要repeat的数组
for (var i = 0; i < $scope.newPages; i++) {
$scope.pageList.push(i + 1);
}
//打印当前选中页索引
$scope.selectPage = function (page) {
//不能小于1大于最大
if (page < 1 || page > $scope.pages) return;
//最多显示分页数5
if (page > 2) {
//因为只显示5个页数,大于2页开始分页转换
var newpageList = [];
for (var i = (page - 3) ; i < ((page + 2) > $scope.pages ? $scope.pages : (page + 2)) ; i++) {
newpageList.push(i + 1);
}
$scope.pageList = newpageList;
}
$scope.selPage = page;
$scope.setData();
$scope.isActivePage(page);
console.log("选择的页:" + page);
};
//设置当前选中页样式
$scope.isActivePage = function (page) {
return $scope.selPage == page;
};
//上一页
$scope.Previous = function () {
$scope.selectPage($scope.selPage - 1);
}
//下一页
$scope.Next = function () {
$scope.selectPage($scope.selPage + 1);
};
});
})
</script>
