if else statement in AngularJS templates

manpreet Best Answer 2 years ago

I want to do a condition in an AngularJS template. I fetch a video list from the Youtube API. Some of the videos are in 16:9 ratio and some are in 4:3 ratio.

I want to make a condition like this:

if video.yt$aspectRatio equals widescreen then 
    element's attr height="270px"
else
    element's attr height="360px"

I'm iterating the videos using ng-repeat. Have no idea what should I do for this condition:

• Add a function in the scope?
• Do it in template?

In the latest version of Angular (as of 1.1.5), they have included a conditional directive called ngIf. It is different from ngShow and ngHide in that the elements aren't hidden, but not included in the DOM at all. They are very useful for components which are costly to create but aren't used:

<div ng-if="video == video.large">
    
div>
<div ng-if="video != video.large">
