[英]AngularJs controller doesn't wait for $http request
I'm new to Angular and a little confused with promises. 我是Angular的新手,对Promise有点困惑。 I've created a custom directive that should show the information coming from a remote web service.
我创建了一个自定义指令,该指令应显示来自远程Web服务的信息。
Here's a factory responsible for data retrieval : 这是一家负责数据检索的工厂:
myAppModule.factory('Data', function ($http)
{
var PID = 7499;
return $http({method: "GET", url: "http://localhost:7001/Nama/services/helloworld/bookingInit", params: {pid: PID}});
});
This is the directive that should show the information coming from this service : 这是应该显示来自此服务的信息的指令:
myAppModule.directive("timePeriods", function ()
{
return {
restrict: 'E',
templateUrl: 'timePeriods.html',
controllerAs: 'periodsCtrl',
controller: ['Data', function (Data)
{
Data.success(function (res)
{
this.periods = res.appointments;
});
}]
}
});
finally here's the template for the directive : 最后是指令的模板:
<table class="table table-bordered" ng-class="'noselect'">
<td colspan="2">
<h4>TIMESLOTS</h4>
</td>
<tr ng-repeat="period in periodsCtrl.periods">
<td>
<div>{{period.start | date : 'hh:mm'}} - {{period.end | date : 'hh:mm'}}</div>
</td>
</tr>
</table>
So I expect the information from the service to be displayed in a table, but when the page is rendered this table is empty.. 因此,我希望来自服务的信息显示在一个表中,但是在呈现页面时,该表为空。
You need to use scope.$apply for the changes to take effect. 您需要使用scope。$ apply才能使更改生效。 AngularJS and scope.$apply
AngularJS和scope。$ apply
