About UI page processing scripts

[bonsai]

I want to run a server-side script using a client script on a UI page.

I know how to call a script include from a client script, but is it possible to call code written in a UI page's processing script from the UI page's client script?

Hi @bonsai ,

For using direct server side logic in UI page, ServiceNow allows us to write a code in jelly script as below. 

 <g:evaluate>
 var userRoles = new GlideRecord('sys_user_has_role');
    userRoles.addQuery('user','${jvar_user_id}');
    userRoles.query(); 
  </g:evaluate>

There are 2 versions of the jelly script in the platform. Please refer to existing UI pages for more details. 

My recommendation would be to avoid the jelly script if it is not much of worth.

@bonsai 

there are 2 ways

1) within client script of UI page use GlideAjax

OR

2) run server side script within processing script of UI page. remember for this to work you need to use <g:ui_form> and need to submit the form so that controls goes to UI page processing script

If my response helped please mark it correct and close the thread so that it benefits future readers.

Can scripts implemented in this way be run from a client script?
