Applying condition to Angular's limitTo filter

Using an AngularJS filter method on a repeated array of items and attempting to filter numbers with a limitTo filter.

Take a look at my JsFiddle code snippet.

The filter is functioning properly, but there is a condition ng-if="!o.IsFeaturedEvent" where the filter should only apply to event listings that are not considered IsFeaturedEvent. Currently, it is applying to all events.

How can I effectively use limitto with the ng-if condition?

If you have any suggestions or solutions, please provide them. Thank you!

Answer №1

If you want to filter out featured events in AngularJS, you can create a custom filter as shown below:

.filter('nonFeaturedEvent', function() {
  return events => events.filter(e => !e.IsFeaturedEvent);
})

Make sure to apply this custom filter before limiting the number of items displayed, like so:

<div ng-repeat="o in data | nonFeaturedEvent | limitTo:limit" ng-if="!o.IsFeaturedEvent">

This nonFeaturedEvent filter will exclude any featured events before applying the limitTo filter.

Check out this fiddle for a simplified demonstration of this concept.

Answer №2

Avoid using ng-if, opt for filter instead.

I conducted a test on your code using 

"o in data | filter: !o.IsFeaturedEvent | limitTo:limit "

The result was the display of the first event, which happened to be a featured event.

If you wish to showcase non-featured events, then utilize

"o in data | filter: o.IsFeaturedEvent | limitTo:limit "
