Angular：DOM中的条件元素？ [英] Angular: Conditional element in DOM?

问题描述

在AngularJS中，

只有当一个范围变量为真时，我才能使HTML存在？

我知道有 ng-show 指令，但这对我来说不起作用，因为它只会使 display：none ，但我需要的实际是该元素只在DOM中存在，当评估某事时。

类似这样的东西对我来说很有用：< div ng-exists =myvar == myothervar>< / div>

解决方案

您可以使用Angular的 ng-if 指令（请参阅

 < div ng-if =myvar == myothervar >< / DIV> 
  

In AngularJS,

how would I make a HTML exist only if a scope variable is true?

I know there is the ng-show directive but this will not work for me as it will only make it invisible with display: none, but what I need is actually that the element only exists in the DOM when something evaluates.

Something like this would work for me: <div ng-exists="myvar==myothervar"></div>

解决方案

You can use Angular's ng-if directive (see the docs):

<div ng-if="myvar==myothervar"></div>
