Help with XMLHttpRequest

[Sharanya Braja Patnaik]

Hi,

I am trying to POST some data from one web page to a another web page using  a simple XMLHttpRequest. But, I am getting the below error in the browser console:

Access to XMLHttpRequest at 'https://script.google.com/macros/.../exec?page=xhrPOST' from origin 'https://n-vyagdopnmsgy6gudvqtfoymdagns4u7h2hhal4q-0lu-script.googleusercontent.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

In some forums, I saw that one can change the CORS settings in the server if one uses google cloud. But I am using a free google account, so unable to change any settings on server side.

Is there anyway to overcome this?

Regards

Braja

Are you attempting to send a message from one Google apps script webpage to another google apps script webpage? If so, you can cache the data and long poll the cache.

Yes, I am posting data from one  Google apps script webpage to another google apps script webpage.

Thank you for your suggestion. Will try out the cache solution!
