Google Apps Script – search YouTube videos by location – part 013.

This is a simple example of how to search on YouTube by location. You need to use the same steps as in my previews tutorials. Use this source code of Google Apps Script to see result into menu: View Logs.

// Apps Script to remove parameters that don't have values before sending API request
function removeEmptyParams(params) {
  for (var p in params) {
    if (!params[p] || params[p] == 'undefined') {
      delete params[p];
    }
  }
  return params;
}

// Apps Script code for printing API response data

function printResults(response) {
  Logger.log(response);
}

function searchListByLocation(part, params) {
  params = removeEmptyParams(params); // See full sample for function

  var response = YouTube.Search.list(part,
      params);
  printResults(response);
}

function Main() {
  searchListByLocation('snippet', {'location': '47.4616,26.3015',
'locationRadius': '10mi',
'q': '',
'type': 'video'});
}

function removeEmptyParams(params) {

for (var p in params) {

if (!params[p] || params[p] == 'undefined') {

delete params[p];

}

return params;

}

// Apps Script code for printing API response data

function printResults(response) {

Logger.log(response);

}

function searchListByLocation(part, params) {

params = removeEmptyParams(params); // See full sample for function

var response = YouTube.Search.list(part,

params);

printResults(response);

}

function Main() {

searchListByLocation('snippet', {'location': '47.4616,26.3015',

'locationRadius': '10mi',
