如何从AngularFire中的对象数组中获取关键名称 [英] How to pull key name from array of objects in AngularFire
问题描述
总之,如何获得2015-02-27T20:24:11-06:00?我可以拉出item.count,item.handle,item.img_url,但{{item。$ id}}不起作用。
obj。$ asArray();
obj。$ asObject();
$ asArray(png) )并将它保存在 $ scope.data
上,你应该简单地得到 $ id
< div ng-repeat =item in data>
< p> id:{{item。$ id}}< / p>
< / div>
但是,我不禁注意到你的套在 $ Id
是错误的。
Can someone help me pull the unique object name from contents ($Id). I'm able to loop over $scope.data in my template with ng-repeat but I can't get the name of that array. Need this to build a URL reference.
In short, how do I get "2015-02-27T20:24:11-06:00"? I can pull out item.count, item.handle, item.img_url, but {{item.$id}} doesn't work.
obj.$asArray();
obj.$asObject();
If you fetch the data $asArray()
and save it on $scope.data
you should simply be able to get the $id
as you describe.
<div ng-repeat="item in data">
<p>id: {{item.$id}}</p>
</div>
However, I can't help but notice that your casing in $Id
is wrong.
