angular 学习笔记，3 ng-repeat遍历json并且给样式

视图：

<div ng-app="myapp" ng-controller="myctrl">
<ul>

        <li ng-repeat="(k,v) in data" color: red':''}}">  <!--给偶素行添加样式-->
          {{k}}
          名称:{{v.name}}
          网址:{{v.url}}
        </li>
<li ng-repeat="(k,v) in data">
<span ng-if="$first" color:red':''}}">
{{v.name}} {{v.url}}
</span><!--第一个元素添加红色-->

<span ng-if="$middle" color:blue':''}}"></span><!--中间元素添加蓝色-->

{{v.name}} {{v.url}}

<span ng-if="$last" color:black':''}}"></span><!--最后一个元素添加黑色-->

{{v.name}} {{v.url}}

</li>
</ul>

</div>

控制器：

var app = angular.module('myApp',[]);
        app.controller('myCtrl',function($scope){
                 $scope.data = [
            {name:'成都人',url:'chengduren.com'},
            {name:'成都网',url:'chengduwang.com'},
            {name:'成都云',url:'chengduyun.com'},
            {name:'hdphp',url:'hdphp.com'},
            {name:'hdcms',url:'hdcms.com'},
        ];
        });
