重复
$index 当前索引
$first 是否为头元素
$middle 是否为非头非尾元素
$last 是否为尾元素
例子一:
<div ng-controller="TestCtrl">
<ul ng-repeat="member in obj_list">
<li>{{ member }}</li>
</ul>
</div>
angular.module('app', [], angular.noop)
.controller('TestCtrl', function($scope){
$scope.obj_list = [1,2,3,4];
});
angular.bootstrap(document.documentElement, ['app']);
例子二:
<div ng-controller="TestCtrl">
<ul ng-repeat="member in obj_list">
<li>{{ $index }}, {{ member.name }}</li>
</ul>
</div>
angular.module('app', [], angular.noop)
.controller('TestCtrl', function($scope){
$scope.obj_list = [{name: 'A'}, {name: 'B'}, {name: 'C'}];
});
angular.bootstrap(document.documentElement, ['app']);
奇偶
ng-class-even 和 ng-class-odd 是和 ng-repeat 配合使用的：
<ul ng-init="l=[1,2,3,4]">
<li ng-class-odd="'odd'" ng-class-even="'even'" ng-repeat="m in l">{{ m }}</li>
</ul>
赋值
<div ng-controller="TestCtrl" ng-init="a=[1,2,3,4];">
<ul ng-repeat="member in a">
<li>{{ member }}</li>
</ul>
</div>
