AngularJS 表格
AngularJS ng-repeat 指令可以完美的显示表格
数据准备
假设我们有一个存储了客户信息的 JSON 文件 customer.json 内容如下
{ "records":[ {"Name":"Alfreds Futterkiste","City":"Berlin","Country":"Germany"}, {"Name":"Ana Trujillo Emparedados y helados","City":"México D.F.","Country":"Mexico"}, {"Name":"Antonio Moreno Taquería","City":"México D.F.","Country":"Mexico"}, {"Name":"Around the Horn","City":"London","Country":"UK"}, {"Name":"B's Beverages","City":"London","Country":"UK"}, {"Name":"Berglunds snabbköp","City":"Luleå","Country":"Sweden"}, {"Name":"Blauer See Delikatessen","City":"Mannheim","Country":"Germany"}, {"Name":"Blondel père et fils","City":"Strasbourg","Country":"France"}, {"Name":"Bólido Comidas preparadas","City":"Madrid","Country":"Spain"}, {"Name":"Bon app'","City":"Marseille","Country":"France"}, {"Name":"Bottom-Dollar Marketse","City":"Tsawassen","Country":"Canada"}, {"Name":"Cactus Comidas para llevar","City":"Buenos Aires","Country":"Argentina"}, {"Name":"Centro comercial Moctezuma","City":"México D.F.","Country":"Mexico"}, {"Name":"Chop-suey Chinese","City":"Bern","Country":"Switzerland"}, {"Name":"Comércio Mineiro","City":"São Paulo","Country":"Brazil"} ] }
在表格中显示数据
下面是对 ng-repeat 的简单使用
<!DOCTYPE html> <meta charset="utf-8"> <link href="/static/next/css/tryit.css?v=2017082407" rel="stylesheet"/> <script src="https://cdn.staticfile.org/angular.js/1.6.3/angular.min.js"></script> <div ng-app="myApp" ng-controller="customersCtrl"> <table> <tr ng-repeat="x in names"> <td>{{ x.Name }}</td> <td>{{ x.Country }}</td> </tr> </table> </div> <footer>简单教程，简单编程<br/>Copyright © 简单教程 www.twle.cn</footer> <script> var app = angular.module('myApp', []); app.controller('customersCtrl', function($scope, $http) { $http.get("/static/tiy/html/angularjs/customer.json") .then(function (result) { $scope.names = result.data.records; }); }); </script>
废弃声明 (v1.5)
v1.5 中
$http的success和error方法已废弃,请使用then方法替代
如果你使用的是 v1.5 以下版本，可以使用以下代码
<script> var app = angular.module('myApp', []); app.controller('customersCtrl', function($scope, $http) { $http.get("/static/tiy/html/angularjs/customer.json") .success(function (response) {$scope.names = response.records;}); }); </script>
添加 CSS 样式
为了让页面更加美观，我们可以在页面中使用 CSS
<style> table, th , td { border: 1px solid #ddd; border-collapse: collapse; padding: 5px; } table tr:nth-child(odd) { background-color: #eee; } table tr:nth-child(even) { background-color: #ffffff; } </style>
使用 orderBy 过滤器排序
<table> <tr ng-repeat="x in names | orderBy : 'Country'"> <td>{{ x.Name }}</td> <td>{{ x.Country }}</td> </tr> </table>
使用 uppercase 过滤器将国家转换为大写
<table> <tr ng-repeat="x in names"> <td>{{ x.Name }}</td> <td>{{ x.Country | uppercase }}</td> </tr> </table>
显示序号 ( $index )
<table> <tr ng-repeat="x in names"> <td>{{ $index + 1 }}</td> <td>{{ x.Name }}</td> <td>{{ x.Country }}</td> </tr> </table>
使用 $even 和 $odd 奇偶行
<table> <tr ng-repeat="x in names"> <td ng-if="$odd" style="background-color:#eee">{{ x.Name }}</td> <td ng-if="$even">{{ x.Name }}</td> <td ng-if="$odd" style="background-color:#eee">{{ x.Country }}</td> <td ng-if="$even">{{ x.Country }}</td> </tr> </table>
