Angular-Isotope Example track by

Use ng-repeat with "track by"

Angular Saves and Restores Isotope's Model

In the newer vesions of Angular, elements are reused if you use the "ng-repeat / track by" combination. If the original model reappears, Angular will assign the original DOM element back to it. Additionally, a new element added to the original array will be indicated as $last=true, which makes Angular-Isotope do an automatic refresh.

The original element is identified by the "track by" key name, such as "name" or "date". This is not a true, hashed-object comparison. If an object has the same key as an earlier object, the corresponding DOM element will be attached to it.

Using "track by" in ng-repeat

• {{x.name}}
  {{x.date | date}}
  {{x.number}}
