javascript - angularJS filter expression in ng-repeat -


i know elegant , simple way implement this. need add filter expression ng-repeat filter 2 conditions 1 property.

in example http://plnkr.co/edit/omqxxvsjtuudmrge4ez8?p=preview

  • if enter a, display checkbox a,
  • enter b - display checkbox b.

but want display specified checkboxes plus empty condition. there no condition c, so:

  • if enter a, want display both , c checkboxes,
  • enter b, want display both b , c checkboxes.

i create custom filter like:

app.filter('myfilter', function() {    return function( items, condition) {     var filtered = [];      if(condition === undefined || condition === ''){       return items;     }      angular.foreach(items, function(item) {                  if(condition === item.condition ||  item.condition === ''){          filtered.push(item);        }     });      return filtered;   }; });

and usage:

<span ng-repeat="charge in charges  |  myfilter:level.condition">

see demo in plunker

it looks pretty elegant , clear.

hope
