在用 restangurlar 来跟后台 api 交互的时候，删除一条记录，但是直接显示在页面中。第三方异步的数据没办法立即同步，如果要看到删除的结果要重新刷新页面的话就太不 cool 了，google 了一把找到解决方法。

原始 js 代码如下：

.controller('HostCtrl', ['$scope','Restangular',function($scope,Restangular) {
    var baseHosts = Restangular.all('api/host');

    $scope.hosts=baseHosts.getList().$object;

    $scope.del=function(host,uuid){
        Restangular.one('api/host',uuid).remove()
        }
}])

html:

<tbody>
<tr ng-repeat="host in hosts|filter:searchText">
    <td><a href="#" ng-if="host.Uuid!=nil" ng-click="del(host,host.Uuid)">deletea> td>
    <td class="center">{{host.Hostname}}td>
    <td class="center">{{host.Ip}}td>
    <td><p ng-repeat="tcp_port in host.Tcp_list">{{tcp_port}}p>td>
    <td><p ng-repeat="udp_port in host.Udp_list">{{udp_port}}p>td>
tr>
tbody>

修改后的 js 代码如下：

.controller('HostCtrl', ['$scope','Restangular',function($scope,Restangular) {
    var baseHosts = Restangular.all('api/host');

    $scope.hosts=baseHosts.getList().$object;

    $scope.del=function(host,uuid){
        Restangular.one('api/host',uuid).remove().then(function(){
            var index=$scope.hosts.indexOf(host);
            if(index > -1) $scope.hosts.splice(index,1);
        })
        }
}])
