这是我的代码:

JS

var app = angular.module('myapp', []);

app.controller('searchCtrl', ['$scope', '$http', function($scope, $http) {

您可以编写一个自定义filter函数,该函数可以根据范围过滤出项目。像这样:

$scope.searchSize = function(obj) {
  if($scope.size && obj.size) {
    var range = $scope.size.split("-");
    if(obj.size >= Number(range[0]) && obj.size <= Number(range[1])) {
      return true;
    }
    return false;
  } 
  return true;
}
