I'm using API JavaScript Client with Calendar, but I have an error!
Perhaps somebody knows what is happening.

Thanks a lot.

This is the error:

Uncaught TypeError: Cannot read property 'events' of undefined

And this is my code:

<!DOCTYPE html>
<html>
  <head>
    <meta charset='utf-8' />       


        var apiKey = 'xxxxxxx';
   

        function makeRequest(){
            console.log('Google Calendar API loaded.');

            gapi.client.calendar.events.list({'calendarId' : 'xxxxxxxx'}).then(function(resp){ //This line throws the error
                console.log(resp.result.item);
            }, function(reason){
                console.log('Error '+reason.result.error.message)
;
            });
  
        }
   
   
        function init(){
            gapi.client.setApiKey(apiKey);
            gapi.client.load('Calendar API', 'v3').then(
                makeRequest()
            );
        }
 
    </script>

    <script type="text/javascript" src="https://apis.google.com/js/client.js?onload=init"></script> 

  </head>
 
  <body>
   
   
  </body>
</html>

Looks like gapi.calendar is undefined. Maybe you don't have the library losses on the page? Do a console.log on that our a debugger; so you can see if you have access to it. Any other console errors?

https://developers.google.com/api-client-library/javascript/start/start-js will, most likely be helpful to you.

This is the other error in console:


I thought that it wasn`t important, but now, I don't know...

I learned to use this client in this page:
https://developers.google.com/api-client-library/javascript/start/start-js and in this other:
https://developers.google.com/api-client-library/javascript/dev/dev_jscript?hl=es

Thank a lot for your help!

You are asking for the api incorrectly:

gapi.client.load('calendar', 'v3', function() {

is the correct "name"

This blog post may help you as well (unaffiliated with myself)

I also tried defining the callback function of gapi.client.load instead of a promise, in this case, the first error is eliminated, but the second error continue:

Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('file://') does not match the recipient window's origin ('null').

I think that this error isn't in the code.

This error perhaps is saying me this:

The JavaScript client library does not support local pages and the file:// protocol.
