While embedding the gadget in the google site, getting error as "TypeError:
google.visualization.GadgetHelper is not a constructor". Incidentally it
was working till recently but stopped working since few days back.
var queryString = prefs.getString("_table_query_url");
var gadgetHelper;
// Register our on-load handler for this gadget.
gadgets.util.registerOnLoadHandler(init);
// Entry point for our gadget.
function init() {
loadVisualizationAPI();
}
// Load the API we are using and kickoff a query.
function loadVisualizationAPI() {
google.load('visualization', '1', {'packages': ['table']});
google.setOnLoadCallback(sendQuery);
}
// Send and handle a query.
function sendQuery() {
gadgetHelper = new google.visualization.GadgetHelper();
var query = gadgetHelper.createQueryFromPrefs(prefs);
query.setQuery('select *');
query.send(handleQueryResponse);
}
