如何将 jsonp 与 angular-ui 日历一起使用 [英] How do I use jsonp with angular-ui calendar

问题描述

我正在使用 angular-ui 日历来尝试从我的 API 中提取事件.API 位于单独的域中，因此我必须使用 jsonp.

我尝试了各种方法来实现这一目标，但无法将活动添加到我的日历中.

我构建了一个调用 API 的服务

angular.module('myapp.services', ['ngResource']).factory('SurgerySource', ['$resource', function($resource){返回$资源('http://api.mydomain.com/calendar.json?callback=JSON_CALLBACK&start=:start&end=:end',{开始:'@start'，结束:'@end'}，{ jsonp_query: { 方法: 'JSONP', isArray: true } });}]);

在我的日历控制器中，我可以直接调用它并获取日历上的事件

angular.module('myapp.schedule', ['ui.calendar', 'ui.bootstrap', 'myapp.services']).controller('ScheduleCtrl', function ScheduleCtrl( $scope, SurgerySource ) {$scope.surgeries = SurgerySource.jsonp_query({开始:1396162800，结束:1399791600});$scope.uiConfig = { ... };$scope.eventSources = [$scope.surgeries];});

这会使用硬编码的日期范围填充日历.我无法找到一种方法来从日历视图中获取开始和结束范围以供使用，因此我尝试使用调用函数的事件源(根据此处的文档 http://angular-ui.github.io/ui-calendar/) 这从视图中获取日期范围，但是我无法将返回的 json 放回到 $scope 中.

 $scope.eventSource = 函数(开始、结束、回调){s = 新日期(开始).getTime()/1000;e = 新日期(结束).getTime()/1000;var eventPromise = SurgerySource.jsonp_query({开始: s，结束:e});回调(事件承诺)；};

如果我检查 eventPromise，我会发现它是一个带有数据的对象(作为数组?)，旁边还有一个 $promise 对象和 $resolved:

<预><代码>[0 ->资源1 ->资源2 ->资源$promise ->目的$已解决 ->真的]

回调不会做任何事情，事件也不会被放到日历上.

我也试过把这个函数放到配置中的 viewRender 中.

$scope.uiConfig = {日历:{高度:450，可真实，标题:{左:'标题'，中央: ''，右:'今天上一个，下一个'},事件点击:$scope.alertOnEventClick，视图渲染:函数(视图，元素){$scope.surgeries = SurgerySource.jsonp_query({开始:view.visStart.getTime()/1000,结束:view.visEnd.getTime()/1000});控制台日志($scope.surgeries)；}}};$scope.surgeries = [];$scope.eventSources = [$scope.surgeries];

我看到日历打开时记录的数据，但事件未填充到日历中.

所以我要么需要弄清楚如何从日历视图中获取日期范围，这样我就可以使用我的硬编码方法.或者我需要弄清楚如何从 promise(?) 对象中获取资源数据并将其发送到 $scope.eventSources

解决方案

我通过切换到 $http 而不是构建服务来解决这个问题.我的新 eventSource 函数看起来像这样

$scope.eventSource = 函数(开始、结束、回调){var startDate = start.getTime()/1000;var endDate = end.getTime()/1000;var url = 'http://api.mydomain.com/app_dev.php/calendar.json?callback=JSON_CALLBACK&start='+startDate+'&end='+endDate;$http.jsonp(url).then(功能(响应){回调(响应数据)；});};

我还必须确保我的消息来源发送的是我的时间戳而不是日期字符串.

I'm using angular-ui calendar to try and pull events from my API. The API is on a separate domain so I have to use jsonp.

I've tried various ways to get this working but can't get the events onto my calendar.

I built a service to call the API

angular.module('myapp.services', ['ngResource'])
.factory( 'SurgerySource', ['$resource', function($resource){
    return $resource(
        'http://api.mydomain.com/calendar.json?callback=JSON_CALLBACK&start=:start&end=:end',
        {start:'@start', end:'@end'},
        { jsonp_query: { method: 'JSONP', isArray: true } }
    );
}]);

In the controller for my calendar I can call it directly and get events on the calendar

angular.module('myapp.schedule', ['ui.calendar', 'ui.bootstrap', 'myapp.services'])
.controller('ScheduleCtrl', function ScheduleCtrl( $scope, SurgerySource ) {
    $scope.surgeries = SurgerySource.jsonp_query({
        start: 1396162800,
        end: 1399791600
    });
    $scope.uiConfig = { ... };
    $scope.eventSources = [$scope.surgeries];
});

This populates the calendar with the hardcoded date range. I couldn't figure a way to get the start and end range out of the calendar view to use though, so I tried to use an event source that calls a function (as per the documentation here http://angular-ui.github.io/ui-calendar/) This gets the date range from the view, but I can't get the returned json back into the $scope.

 $scope.eventSource = function (start, end, callback) {
     s = new Date(start).getTime() / 1000;
     e = new Date(end).getTime() / 1000;
     var eventPromise = SurgerySource.jsonp_query({
         start: s,
         end: e
     });
     callback(eventPromise);
 };

If I inspect eventPromise, I see it is an abject with the data in there (as an array?) along side a $promise object and $resolved:

[
  0 -> Resource
  1 -> Resource
  2 -> Resource
  $promise -> Object
  $resolved -> true
]

The callback doesn't do anything though and the events are not put onto the calendar.

I also tried to put this function into viewRender in the config.

$scope.uiConfig = {
    calendar:{
        height: 450,
        editable: true,
        header:{
            left: 'title',
            center: '',
            right: 'today prev,next'
        },
        eventClick: $scope.alertOnEventClick,
        viewRender: function(view,element) {
            $scope.surgeries = SurgerySource.jsonp_query({
                start: view.visStart.getTime()/1000,
                end: view.visEnd.getTime()/1000
            });
            console.log($scope.surgeries);
        }
    }
};
$scope.surgeries = [];
$scope.eventSources = [$scope.surgeries];

I see the data logged when the calendar opens, but the events are not populated to the calendar.

So I either need to work out how to get the date range out of the calendar view, so I can use my hard coded method. Or I need to work out how to get the resource data out of the the promise(?) object and send it to $scope.eventSources

解决方案

I got this working by switching to $http instead of building a service. My new eventSource function looks like this

$scope.eventSource = function (start, end, callback) {
    var startDate = start.getTime()/1000;
    var endDate = end.getTime()/1000;
    var url = 'http://api.mydomain.com/app_dev.php/calendar.json?callback=JSON_CALLBACK&start='+startDate+'&end='+endDate;

    $http.jsonp(url)
        .then(function(response){
            callback(response.data);
        });
};

I also had to make sure my source was sending my timestamps rather than date strings.
