循环输出多个标题:
<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 = [ "菜鸟学堂1", "菜鸟学堂2", "菜鸟学堂3", "菜鸟学堂4", ] }); </script> </body>尝试一下 »
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。
<element ng-repeat="expression"></element>
所有的 HTML 元素都支持该指令。
值 | 描述 |
---|---|
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 $id(x) |
使用数组循环输出一个表格:
<table ng-controller="myCtrl" border="1"> <tr ng-repeat="x in records"> <td>{{x.Name}}</td> <td>{{x.Country}}</td> </tr> </table> <script> var app = angular.module("myApp", []); app.controller("myCtrl", function($scope) { $scope.records = [ { "Name" : "Alfreds Futterkiste", "Country" : "Germany" },{ "Name" : "Berglunds snabbköp", "Country" : "Sweden" },{ "Name" : "Centro comercial Moctezuma", "Country" : "Mexico" },{ "Name" : "Ernst Handel", "Country" : "Austria" } ] }); </script>尝试一下 »
使用对象循环输出一个表格:
<table ng-controller="myCtrl" border="1"> <tr ng-repeat="(x, y) in myObj"> <td>{{x}}</td> <td>{{y}}</td> </tr> </table> <script> var app = angular.module("myApp", []); app.controller("myCtrl", function($scope) { $scope.myObj = { "Name" : "Alfreds Futterkiste", "Country" : "Germany", "City" : "Berlin" } }); </script>尝试一下 »
