我正在尝试根据范围过滤元素。我正在使用两个控制器和$rootScope
广播方法来检索滑块的最小-最大范围并与另一个控制器共享它。
HTML-
<body ng-app="myApp">
<div ng-controller="RangeController as vm">
<rzslider rz-slider-model="vm.slider.minValue" rz-slider-high="vm.slider.maxValue" rz-slider-options="vm.slider.options"></rzslider>
</div>
<div ng-controller="SampleController">
<div ng-repeat="x in elements | inRange:min:max">
{{x}}
</div>
</div>
</body>
AngularJS-
var app = angular.module('myApp', ['rzModule']);
app.controller('SampleController', function($scope,$rootScope) {
$scope.min = 1500;
$scope.max = 5500;
$scope.elements = [1530,2100,2780,3323,3420,4680,5020,5300,5402];
$scope.$on('MIN_PRICE', function(response) {
$scope.min = minPrice;
})
$scope.$on('MAX_PRICE', function(response) {
$scope.max = maxPrice;
})
});
app.value('minPrice',1500);
app.value('maxPrice',5500);
app.controller('RangeController', RangeController);
function RangeController($scope,$rootScope) {
var vm = this;
vm.changeListener = function() {
minPrice = vm.slider.minValue;
maxPrice = vm.slider.maxValue;
console.log(minPrice + " " +maxPrice);
$rootScope.$broadcast('MIN_PRICE', minPrice);
$rootScope.$broadcast('MAX_PRICE', maxPrice);
};
vm.slider = {
minValue: 1500,
maxValue: 5500,
options: {
floor: 1500,
ceil: 5500,
step: 500,
translate: function(value) {
return '₹' + value;
},
onChange:vm.changeListener
}
}
}
app.filter('inRange', function() {
return function(array, min, max) {
array = array.filter(function(element) {
return (element >= min && element <= max);
});
console.log(array);
};
});
我尝试调试,过滤器工作正常,但它不会反映在模板中。
