我一直试图解决这个问题好几天。 我试图使用复选框过滤Json数据，例如当我选中多个ID时，它会显示其余的id数据 enter image description here
如果用户选中复选框（型号），将根据这些复选框选择
过滤模型
controller('compareModelsCtrl',['$scope','$http', '$state' ,'$location',
function($scope, $http, $state,$location, filterFilter) {
$http.get('js/data.json').success(function(data){
$scope.models = data;
$scope.whichmodel = $state.params.modelId;
$scope.order = {};
$scope.format=function(){
$scope.modifiedOrder=[];
angular.forEach($scope.order, function(value, key) {
if(value){
$scope.modifiedOrder.push(parseInt(key));
}
});
<ion-checkbox ng-repeat="model in models | filter:query" ng-model="order[model.id]" ng-change="format()">{{model.model_number}}</ion-checkbox>
</ion-item>
current order : {{modifiedOrder}}

你的问题中存在格式问题。
其次，您需要使用过滤功能。我创建了一个名为selectedObjects的过滤对象，并修改了format函数中的值，并在HTML中显示如下。
<ion-checkbox ng-repeat="model in models | filter:query" ng-model="order[model.id]" ng-change="format()">{{model.model_number}}</ion-checkbox>
<pre>
current order : {{modifiedOrder}} <br>
selected objects:{{selectedObjects}} </pre>
和JS
此实现假定id在JSON中是唯一的。
$scope.order = {};
$scope.format = function() {
$scope.modifiedOrder = [];
$scope.selectedObjects = [];
angular.forEach($scope.order, function(value, key) {
if (value) {
var filtered = $scope.models.filter(function(unit) {
return unit.id === key
});
$scope.selectedObjects.push({
"overall_length":filtered[0].overall_length,
"contour_length": filtered[0].contour_length
});
$scope.modifiedOrder.push(parseInt(key));
}
});
}
