javascript - AngularJS - Apply directive instantly, formating currency -


ok have following directive on various input elements. of elements on modals current method doesn't work how want, should apply right before modal opens.

crtpromodir.directive('ngformatcurr', ['$filter', function($filter) {     function link(scope, element, attrs)     {         element.blur(function()         {             element.val($filter('currency')((element.val() || 0), '', 2));         });     };      return {         link: link     }; }]);

so how can apply filter instantly , every time changes?

solution mccainz:

crtpromodir.directive('ngformatcurr', ['$timeout', '$filter', function($timeout, $filter) {     return {         link: function(scope, element, attrs)         {             $timeout(function()             {                 element.val($filter('currency')((element.val() || 0), '', 2));             });              element.blur(function()             {                 element.val($filter('currency')((element.val() || 0), '', 2));             });         }     }; }]);

to initialize filter change code such filter runs in link function. not try modify value filter on every keypress/change though frustrate user.

updated initialize on $timeout filter applied after angular compilation. added keypress handler , code such filter apply after 2 seconds of keypress. don't recommned addresses issue of having value filter user types, giving 2 second delay after users keypress before filter apply.
