AngularJS ng-repeat 指令

AngularJS 实例

循环输出多个标题:

<!DOCTYPE html><html><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body ng-app="myApp" ng-controller="myCtrl"><h1 ng-repeat="x in records">{{x}}</h1><script>var app = angular.module("myApp", []);app.controller("myCtrl", function($scope) { $scope.records = [ "菜鸟教程1", "菜鸟教程2", "菜鸟教程3", "菜鸟教程4", ]});</script></body></html>

定义和用法

ng-repeat 指令用于循环输出指定次数的 HTML 元素。

集合必须是数组或对象。

语法

<element ng-repeat="expression"></element>

所有的 HTML 元素都支持该指令。

参数值

expression 表达式定义了如何循环集合。

表达式实例规则:

x in records

(key, value) in myObj

x in records track by $id(x)

更多实例

AngularJS 实例

使用数组循环输出一个表格:

<!DOCTYPE html><html><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body ng-app="myApp"><table ng-controller="myCtrl" border="1"><tr ng-repeat="x in records"> <td>{{x.Name}}</td> <td>{{x.Country}}</td> </tr></table><script>var app = angular.module("myApp", []);app.controller("myCtrl", function($scope) { $scope.records = [ {  "Name" : "Alfreds Futterkiste",  "Country" : "Germany" }, {  "Name" : "Berglunds snabbk",  "Country" : "Sweden" }, {  "Name" : "Centro comercial Moctezuma",  "Country" : "Mexico" }, {  "Name" : "Ernst Handel",  "Country" : "Austria" } ]});</script></body></html>

运行结果:

Alfreds Futterkiste Germany
Berglunds snabbk Sweden
Centro comercial Moctezuma Mexico
Ernst Handel Austria

AngularJS 实例

使用对象循环输出一个表格:

<!DOCTYPE html><html><head><meta charset="utf-8"><script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script></head><body ng-app="myApp"><table ng-controller="myCtrl" border="1"><tr ng-repeat="(x, y) in myObj"> <td>{{x}}</td> <td>{{y}}</td> </tr></table><script>var app = angular.module("myApp", []);app.controller("myCtrl", function($scope) { $scope.myObj = { "Name" : "Alfreds Futterkiste", "Country" : "Germany", "City" : "Berlin" }});</script></body></html>
