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>
