Javascript angular js：过滤列表中不需要的项

代码是用js编写的。我可以从json中的链接获取列表，但我需要过滤列表中不需要的项目

如果id超过4位，则删除全名、名称、短名称和id。例如：如果id:123456，则需要将其过滤掉

app.js

  kls: {
      name: "Momo",
      value: "kls",
      long: "KLSE",
      searchRef: KLSE_SEARCH_REF,
      searchRefURL: "http://www.bursamalaysia.com/searchbox_data.json",

    },

  $ionicLoading.show();
  if($scope.currentMarket == "kls") {
    $webServicesFactory.getNotParsed($marketProvider[$scope.currentMarket].searchRefURL).then(
      function success(response) {
        response = JSON.parse(response);
        for(var i=0; i<response[0].length; i+=1){
          $scope.searchRef.push(
            {
              name: response[0][i].name || response[0][i].full_name,
              symbol: response[0][i].short_name,
              code: response[0][i].id,
              market: $marketProvider[$scope.currentMarket].long
            }
          );
        }
        console.info($scope.searchRef);
        $ionicLoading.hide();
      }
    );
  }

details.js

  kls: {
      name: "Momo",
      value: "kls",
      long: "KLSE",
      searchRef: KLSE_SEARCH_REF,
      searchRefURL: "http://www.bursamalaysia.com/searchbox_data.json",

    },

  $ionicLoading.show();
  if($scope.currentMarket == "kls") {
    $webServicesFactory.getNotParsed($marketProvider[$scope.currentMarket].searchRefURL).then(
      function success(response) {
        response = JSON.parse(response);
        for(var i=0; i<response[0].length; i+=1){
          $scope.searchRef.push(
            {
              name: response[0][i].name || response[0][i].full_name,
              symbol: response[0][i].short_name,
              code: response[0][i].id,
              market: $marketProvider[$scope.currentMarket].long
            }
          );
        }
        console.info($scope.searchRef);
        $ionicLoading.hide();
      }
    );
  }

$ionicLoading.show（）；
如果（$scope.currentMarket==“kls”）{
$webServicesFactory.getNotParsed（$marketProvider[$scope.currentMarket].searchRefURL）。然后(
功能成功（响应）{
response=JSON.parse（response）；
对于（var i=0；i尝试构建自定义筛选函数，如：

function filterData(data) {
    return data.filter(function (val) {
        return String(val.id).length <= 4;
    });
}

函数过滤器数据（数据）{
返回数据。过滤器（函数（val）{
返回字符串（val.id）。id的长度在哪里？@Phil edited.missed掉了一行
