Hi All,

I want to load an external JavaScript file and make sure it's not cached. When I update the external file, nuBuilder still loads the old file even when the user logs off and in again.
I thought I can work around that by adding the session_id to the javascript.

I've included an External JavaScript in the header :

Code: Select all

document.write('\x3Cscript type="text/javascript" src="https://apis.google.com/js/client.js?id=' + nuCurrentProperties().session_id + '">\x3C/script>');

but there's an error

Uncaught TypeError: Cannot read property 'session_id' of undefined

session_id is not defined when the header loads. Is there a better place to place it?

Try this (To be placed in Setup -> Header):

Code: Select all

$.getScript('https://apis.google.com/js/client.js', function() {});

By default, $.getScript() sets the cache setting to false. This appends a timestamped query parameter to the request URL to ensure that the browser downloads the script each time it is requested.
