我想在嵌套的ng-repeat中过滤对象.

HTML:

<div ng-controller="MyController">
<input type="text" ng-model="selectedCityId" />
<ul>
    <li ng-repeat="shop in shops">
      <p ng-repeat = "locations in shop.locations | filter:search" style="display: block">
          City id: {{ locations.city_id }}
          <span style="padding-left: 20px; display: block;" ng-repeat="detail in locations.details | filter:item">Pin code: {{detail.pin}}</span>
      </p>    
    </li>
</ul>

控制器:

var myApp = angular.module('myApp', []);

myApp.controller('MyController', function ($scope) {

    $scope.search = function (location) {

        if ($scope.selectedCityId === undefined || $scope.selectedCityId.length === 0) {
            return true;
        }

           if (location.city_id === parseInt($scope.selectedCityId)) {
               return true;
            }
    };

    $scope.item …

当我尝试在本地保存文件时,响应对象返回null.我正在尝试捕获的页面需要大量的加载时间,我需要回调以在所有页面资源完全加载时通知我.我的方法是否正确？

如果不尝试在本地保存文件,则返回的响应对象不为null.

这是我的代码:

$client = Client::getInstance();
$client->getEngine()->setPath('path/to/phantomjs');
    $client->isLazy();

    $request  = $client->getMessageFactory()->createPdfRequest('http://google.com');
    $response = $client->getMessageFactory()->createResponse();

    $file = 'path/binfile.pdf';

    $request->setOutputFile($file);

    $client->send($request, $response);

如何实现并了解所有页面资源何时完全加载？

如何在 angular 4 项目中使用Videojs 插件？许多插件没有 typeScript 声明文件(*.d.ts)
