onChange script error: ReferenceError: GlideDate is not defined function

how to resolve the error: [onChange script error: ReferenceError: GlideDate is not defined function]

Hello @Chenk 

GlideDate() is designed for server-side use only. If you need to perform date manipulation on the client side, you'll need to create a Script Include and then call it from the client script.

Hi @Chenk 

The GlideDateTime object and GlideDate are APIs used in Server side scripts. To use in client side scripts you have to use it Script include s and get it using GlideAjax call.

Hi @Chenk,

GlideDate is a server side method and API, hence the error.

If you simply want the current date time now with no real other thought or consideration, you can use the following syntax to obtain the date via a Client Script.

However, best practice would be to leverage this type of data using something called 'AJAX' or "GlideAjax" (A method used when you need to leverage server side code)

I've attached a link to a great community post with examples of to how to achieve this and use AJAX code from your client script.

var date = new Date();

Please use GlideAjax to make a server call and do the stuff in the script include.

There are ALOT of issues using Javascript Date()
An example:

Its far more reliant to use a GlideAjax call and then do GlideDate / GlideDateTime in the server script.
