Is there a good place to develop client-side scripts?

[bonsai]

There are places to try out server-side scripts, such as script backgrounds and repair scripts, but
is there a suitable place to develop client-side scripts?
It would be great if there was a viable development environment within the instance.
If not, I'll have to use an external product...

Client side code can be tried in console.

1. Right click on any page, click on inspect.

2. Under console tab, if you write the client side script that should work.

3. Alternatively, press Ctrl + Alt + Shift + J  on any form, in your windows machine, it will open javascript executor, you can write client side code there.

Hi @bonsai ,

If you've ever run into trouble creating any client side scripts in your ServiceNow instance (Client Scripts/UI Policies etc.) you may find the following tool very useful. It's known as the Javascript Executor. 

Opening the Javascript executor on your ServiceNow instance:

1. Open an Incident form

2. Press "Alt+Ctrl+Shift+j" to open the Javascript Executor

You can run your client side code here (quite similar to background script for Server Side). If you want to practice it is best but if you want your code to be saved for later use then Type client script in filter naviagtor and write your code in client script.

If my answer helped you, please mark it- solution accepted.

@bonsai ,

There’s no special “background scripts” style editor for client scripts in ServiceNow.

• For server-side you have Background/Fix Scripts.

• For client-side the only way is:

  1. Write them in the Client Script / UI Script record inside the instance.

  2. Test them directly on a form/page in your PDI (or sub-prod instance).

  3. For quick experiments, you can run snippets in the browser console while on a form (good for testing g_form calls).
     Note -  In short: yes — you need to use a PDI/dev instance to test client-side code. There’s no separate built-in diff editor for that.
     
     Hope it helps!

@bonsai 

on any form you can use the javascript executor
