Save filtered data

[Matt Nodurfth]

New to AngularJS and loving it!  

I'm using ngRepeat to filter through JSON.  Is there a way to save the filtered items to another JSON?  I want to use the filtered results later on in my script.  

Cheers,
Matt

You can achieve this with the $filter service. Note that you need to use angular.toJson() on the filtered data because Angular adds $$hashKey key-value pairs to each JSON object.

Syntax:

    $filter('filter')(array, expression)

Example code: http://jsfiddle.net/razh/WQESz/

The code you want is on line 11, with $scope.save().

Thanks Raymond! Is there a way to do this without having a save button, ie, dynamically?

I'm working with leaflet.js and angular.  I'm filtering the imported json with angular and then want to have the map's markers built from that filtered json.

You ever figure this one out?

You could just set a watch on the input.  So that every time a character has been typed, it'll run the save().

This what you mean?

You can do this:

<li  ng-repeat="item in filtered = (myData | filter )">

this will set the result of the filtered MyData to a variable of filtered on the $scope. this is useful if you want to know when a filtered resultset is length=0 too - to show a 'no results' message for instance.

.. you can then watch the filtered value to save it back to json if you want
