Show ng-repeat item only when value to display is not null
提问by trainoasis
I just stared learning AngularJS few days ago. I have a ng-repeat on an element, but I want to use ng-show with it somehow as well. This is my code now:
几天前我刚开始学习 AngularJS。我在一个元素上有一个 ng-repeat，但我也想以某种方式使用 ng-show。这是我现在的代码：
<p ng-repeat="(parameter,value) in object">{{parameter}}: {{value}}</p>
Which works well where object is structured as
在对象结构为
{"MobilePhone":null,"Email":"[email protected]","HomePhone":null}
I want to show only elements that don't have null as a value. Something like:
我只想显示没有 null 作为值的元素。就像是：
<p ng-repeat="(parameter,value) in object" ng-show={{value}}>{{parameter}}: {{value}}</p>
But I don't see why value would be available there for ng-show already? How can I do an "If" check for value before showing
但我不明白为什么 ng-show 已经可以使用价值了？如何在显示之前对值进行“如果”检查
?
?
Thanks for any help. If I was unclear, please ask for more info.
谢谢你的帮助。如果我不清楚，请询问更多信息。

This will work, and only if valueis a truly value it will be shown:
这将起作用，并且仅当value它是真正的值时才会显示：
<p ng-repeat="(parameter,value) in obj" ng-show="value">{{parameter}}: {{value}}</p>
(You can also use ngIfinstead)
（您也可以使用ngIf）
