我设置了一个范围滑块,范围为0-2hr,时间以分钟为单位计算,然后像这样转换为hh:mm:10min,20min,1hr 20min,2hr。
但是现在我正在尝试ng-repeat使用范围滑块指定的范围来过滤一堆项目,而我很难做到这一点。
ng-repeat
这是我所做的http://cdpn.io/LDusa
我正在使用http://danielcrisp.github.io/angular- rangeslider/demo/作为范围滑块。
这是代码:
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(如果您更喜欢HTML,可以使用以下http://html2jade.org/将其转换回html ):
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 }}
我如何才能使其正常工作,以便仅time在范围滑块指定的范围内时才显示项目?
time
将sliderConfig传递到过滤器中,以找到在范围滑块上设置的当前最小值和最大值。确保您的对象位于数组中。
<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具有第二个参数“ rangeInfo”,我们可以从中获取2个值。
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; }; });
希望能帮助到你。
