Angular filtering between range

Question

I set a range slider that ranges from 0 to 2 hours, times are calculated in minutes and then converted to hh: mm, like this: 10min, 20min, 1hr 20min, 2hr.

But now I'm trying to filter out a bunch of elements inside ng-repeat using the range given by the range slider, and it's hard for me to handle it.

Here is what I did http://cdpn.io/LDusa

I am using http://danielcrisp.imtqy.com/angular-rangeslider/demo/ for the range slider.

And here is the code:

 var app = angular.module('myApp', ['ui-rangeSlider']); app.controller('myCtrl', function ($scope) { $scope.sliderConfig = { min: 0, max: 120, step: 10, userMin: 0, userMax: 30 }; $scope.times = [ {"time": "20"}, {"time": "50"}, {"time": "30"}, {"time": "10"}, {"time": "85"}, {"time": "75"}, {"time": "95"}, {"time": "100"}, {"time": "80"}, {"time": "200"}, {"time": "260"}, {"time": "120"}, {"time": "62"}, {"time": "68"}, {"time": "5"}, {"time": "116"} ]; }); app.filter('customFilter', function () { return function (value) { var h = parseInt(value / 60); var m = parseInt(value % 60); var hStr = (h > 0) ? h + 'hr' : ''; var mStr = (m > 0) ? m + 'min' : ''; var glue = (hStr && mStr) ? ' ' : ''; return hStr + glue + mStr; }; }); app.filter('range', function() { return function(input, min, max) { min = parseInt(min); max = parseInt(max); for (var i=min; i<=max; i++) input.push(i); return input; }; }); 

JADE (If you prefer HTML, you can convert it back to html using http://html2jade.org/ ):

 div(ng-app="myApp") div(ng-controller='myCtrl') div(range-slider='', pin-handle='min', attach-handle-values='', prevent-equal-min-max='', step='{{sliderConfig.step}}', min='sliderConfig.min', max='sliderConfig.max', model-min='sliderConfig.userMin', model-max='sliderConfig.userMax', filter='customFilter') div(range-slider, prevent-equal-min-max='', attach-handle-values='', min='sliderConfig.min', max='sliderConfig.max', model-min='sliderConfig.userMin', model-max='sliderConfig.userMax', filter='customFilter') div(ng-repeat="time in times | range:sliderConfig.userMin:sliderConfig.userMax") | {{ item.time | customFilter }} 

How can I get this work to display only those elements when time is within the range specified in the range slider?

Pass the Config slider to the filter to find the current min and max values ​​set on the range slider. Make sure your objects are in an array.

  <div range-slider="range-slider" min="sliderConfig.min" max="sliderConfig.max" model-min="sliderConfig.userMin" model-max="sliderConfig.userMax"> </div> ... // Pass the slider config into the filter <div ng-repeat="time in times | rangeFilter:sliderConfig"> {{ time.time | customFilter}} </div> ... $scope.times = [ {time: '20'}, {time: '50'}, ... ]; 

RangeFilter has a second rangeInfo parameter, which we can get from 2 values.

 app.filter('rangeFilter', function() { return function( items, rangeInfo ) { var filtered = []; var min = parseInt(rangeInfo.userMin); var max = parseInt(rangeInfo.userMax); // If time is with the range angular.forEach(items, function(item) { if( item.time >= min && item.time <= max ) { filtered.push(item); } }); return filtered; }; }); 

Hope this helps.
